Description

Space-saving sound diffusion device for water sports

The present invention relates to the field of electronic accessories for water sports.

The present invention relates more particularly to a sound diffusion device for swimmers which can be fixed on a fastening strap, in particular a fastening strap of a pair of swimming goggles, of a helmet or of a headband of said swimmer, in a stable way and not disturbing the practice of water sports.

By sound diffusion device within the meaning of the present, is meant throughout the following description an electronic device allowing the generation of a sound wave according to a variety of listening systems, in particular by loudspeakers, by intra-auricular listening or by bone conduction. The sound wave can be generated from information recorded in the internal memory or from information received by reception means. Such a device can be used to communicate instructions from a trainer or to play music for comfort or synchronization.

The present invention will thus find many advantageous applications in the field of water sports, in particular in learning and training in swimming, kitesurfing or even canyoning.

State of the art

The Applicant observes that the development of information and communication technologies leads to the proliferation of electronic devices, in particular connected devices allowing information to be exchanged using a variety of communication channels.

This technological development brings in parallel a miniaturization of electronic devices facilitating the use of mobile solutions that can be directly worn by the user.

However, the field of swimming and water sports presents particular constraints that have so far slowed down innovation. Any electronic device associated with such a field must not only respect strict sealing criteria but also have a minimal bulk so as not to interfere with the practice of a sporting discipline and a robust attachment.

To meet such criteria, several swimming goggles incorporate electronic devices arranged at the level of their frame. However, such a solution remains limited by the maximum comfortable size of the glasses and therefore only allows a limited variety of services to be provided. Since electronic devices are also integrated into the eyeglass frame, they are difficult to exchange from one pair of glasses to another and are generally sized for a specific pair of glasses.

Other solutions propose attaching a miniaturized electronic device, in particular a device of the mp3 player type, using an accessory of the clip type allowing attachment to a pair of glasses. However, such a binding lacks robustness with respect to sports practice and cannot be adapted to all models of glasses.

The design of "universal" electronic devices capable of being adapted to a variety of swimming goggles is all the more limited by the structural differences from one model of swimming goggles to another and which may have any shape of frame and/or or tether strap. Extending this adaptability beyond swimming goggles, for example to a sports helmet, further increases the forms of attachment strap to be considered.

The Applicant therefore submits that to date there is no satisfactory alternative solution for attaching an electronic device for swimmers, in particular a sound diffusion device, to a strap for attaching a pair of swimming goggles interchangeably between a plurality of eyewear models.

The present invention aims to improve the current situation described above.

The present invention aims more particularly to remedy the above drawbacks by proposing a sound diffusion device for water sports capable of being attached to a pair of swimming goggles or a helmet having a fastening strap, in a removable and adaptable manner. to the tether strap.

To this end, the object of the present invention relates in a first aspect to a space-saving sound diffusion device for water sports comprising a waterproof casing integrating a miniaturized electronic diffusion module, the device comprising removable fixing means configured to fix the case removably on a fastening strap, in particular a fastening strap for a pair of swimming goggles or a helmet, of a water sports practitioner.

In other words, the device is designed so as to attach in a removable manner to a fastening strap of a pair of swimming goggles or a helmet in order to be held on the side or the back of the head. of the practitioner when the latter is wearing the glasses or the helmet, the main body of the device corresponding to the waterproof casing.

It is understood here that the electronic module comprises a variety of electronic components dedicated to the generation of a sound wave as described above, the electronic components being housed inside the waterproof casing for their protection. The device may also include an audio output external to the box, in particular in-ear headphones connected to said box.

Advantageously, the fastening means are configured to adapt to a plurality of geometric shapes of a cross section of the fastening strap.

It is understood here that the fixing means can correspond to a universal fixing adaptable to a variety of cross-sections, to a plurality of fixing elements associated respectively with one or more specific cross-sections, or even to fixing means comprising interchangeable fasteners depending on the cross-section of the fastening strap.

It is further understood that the tether strap can be associated with any accessory worn on the head of the practitioner, depending on the water sport practiced or the preferences of the practitioner. These can be swimming or diving goggles, a sports or swimming headband or a helmet, for example a canyoning helmet.

The fixing means can additionally be dedicated to a specific portion of the fastening strap, the cross section of which has a shape suitable for fixing a sound diffusion device.

Thanks to the present invention, the sound diffusion device can be attached to a variety of swimming goggles, headphones or other temporarily and can be dissociated at will for recharging, repair or even for a change of the device and / or goggles or helmet.

In an advantageous embodiment of the invention, the case has two internal and external faces opposite each other, the internal face having a flat surface and being intended to rest in contact with the practitioner's head, the face external comprising the fastening means.

It is understood here and throughout the description below that the notions of internal and external face will be taken into consideration of the normal position of the box fixed on the strap when the practitioner wears the swimming goggles or the helmet, the internal face (or proximal) being the closest to the practitioner, the outer (or distal) face being opposite the practitioner.

This design makes it possible to hold the case in position by means of the strap, in particular by means of an elastic strap, the latter applying pressure on the case via its external face in the direction of the practitioner, the flat internal face ensuring comfortable wearing of the casing on the side or back of the practitioner's head.

It is also possible to conceive of other arrangements of the fastening means on the housing, in particular a plurality of fastening means arranged on the external face and the lateral faces of the housing, each fastening means being intended for the fastening of a cross section specific.

In a particular embodiment, the fixing means are configured to adapt to a rectangular or circular shape of the cross section.

These cross-sectional shapes correspond to the majority of straps and allow the device to be adapted to a wide range of swimming goggles and helmets without overly complicating the fastening means used.

In a specific embodiment, the fixing means comprise two branches extending from the casing, curved towards one face of the casing and the free ends of which face each other to form a first passage slot opening onto a first housing for receiving the fastening strap formed by the face of the casing and the internal face of said branches.

It is understood here that the face of the housing towards which the branches extend corresponds to the face of the housing comprising the fixing means, for example the external face of the housing. The branches can extend from this same face of the housing, for example from two opposite ends of this face, or even from faces adjacent to the face comprising the fastening means.

Preferably, the first slot is dimensioned for the passage of the fastening strap in order to accommodate the latter in the first receiving housing.

In other words, the first passage slot allows the insertion of the fastening strap into the first receiving housing. This first receiving housing can be specifically dedicated to adapt to a rectangular cross-sectional shape, in particular a rectangular shape of width less than the width of the first passage slot and of length greater than the width of the first passage slot to facilitate manual removable attachment of the tether strap and prevent accidental dissociation of the case and the strap when practicing water sports. The first receiving housing can of course receive attachment straps having a variety of cross-sections provided that the first passage slot is dimensioned for their insertion.

In an embodiment that can be combined with the previous mode, the branches have an elastic structure.

It is understood here that the branches can deform substantially relative to their rest position. This design facilitates the insertion of a tether strap whose cross section has dimensions greater than the width of the first slot while further limiting the risk of disengagement of the tether strap.

According to a particular design where the internal face of the case includes the fixing means, the elastic structure of the branches additionally makes it possible to deform them by pressing against the practitioner's head, so that the free ends of the branches come into contact and exert a pressure on the tether strap to prevent any movement of the case relative to the tether strap.

In one mode of implementation, the fixing means comprise a closing bar closing off the first passage slot.

It is understood here that the closing strip makes it possible to avoid accidental dissociation of the fastening strap and the housing by preventing the fastening strap from crossing the first passage slot when the closing strip is put in place. This closure can be performed on a portion of the first passage slot or on its entire length depending on the design of the closure strip, without changing its function.

This design allows the case to be adapted to a wider variety of cross-sections by providing stable attachment of the case without imposing a minimum dimension on the cross-section of the tether strap.

Preferably, the closure strip has an H-shaped cross-section forming two grooves in opposition to one another and capable of receiving the free ends of the branches.

In other words, the closure bar has two grooves, each groove being capable of receiving the free end of a branch, so as to ensure physical continuity between the two branches. The grooves and the free ends may additionally comprise means of engagement, for example a snap-fastening system facilitating the positioning of the closure strip between the two branches.

In an additional mode of implementation, the fastening means comprise a gutter associated with the closure bar and having two arms whose free ends face each other to form a second passage slot opening onto a second reception accommodation.

It is understood here that the gutter can be associated with the shutter bar so that the gutter is held in position vis-à-vis the housing by means of the shutter bar.

Depending on the design, the two arms are associated with the internal (towards the housing) or external (opposite to the housing) face of the H cross-section, so that the gutter is contained in the first housing or not.

Preferably, the gutter and the closure strip form a single piece element, the two arms having the H-shaped cross-section, the H-shaped cross-section having the second passage slot.

It is understood here that the cross-section in H is formed by the continuity of the two arms, the second passage slot being contained in the first passage slot.

In another mode of implementation, the gutter and the closure bar form two distinct elements, the two arms having two grooves engaging on complementary tabs of the closure bar.

It is understood here that the gutter is able to engage on the closing bar so that the closing bar closes the second passage slot. The complementary lugs of the closure strip correspond, for example, to the ends of the H-shape of the closure strip or even to additional elements to this H-shape and intended to receive the free ends of the gutter. It is also possible to design two additional grooves included in the H-shape of the closing bar suitable for receiving the free ends of the arms

Preferably, the gutter has an internal section of circular or oval shape.

It is understood here that the shape of the second reception housing is defined by the internal section of the gutter. This shape preferably corresponds to that of the cross-section of the fastening strap and is sized so that the second housing is adjusted on the fastening strap to prevent any displacement of the housing on the fastening strap.

It is additionally understood that it is possible to provide a variety of gutters that can be adapted to the same closure strip or closure strips provided with gutters, each gutter being adapted for the reception in the second housing of a cross section of the attachment strap, so as to calibrate the gutter in relation to the attachment strap.

In one mode of implementation that can be combined with the previous mode, the arms of the gutter have an elastic structure.

In a similar way to the elastic structure described above, the arms can be deformed substantially with respect to their position of rest, with the aim of temporarily widening the second passage slot for the insertion of a fastening strap on which the splint is fitted.

In yet another mode of implementation, the closure bar comprises means for locking in translation.

It is understood here that the locking means make it possible to block the movement of the closure strip relative to the housing and/or the movement of the gutter relative to the closure strip, in the case where these form two elements distinct.

Preferably, the locking means comprise a stop fixed to a first end of the shutter bar and a latch fixed to a second end of the shutter bar and configured to pass from an open position where the latch is positioned in extending the shutter bar to a closed position where the latch is raised to block movement of the shutter bar.

It is understood here that the shutter strip can be engaged on the branches of the housing and/or receive the arms of the gutter by its second end when the latch is in the open position until the branches and/or the arms enter in contact with the stopper. The latch can then be raised and serve as a second stop to prevent any dissociation of the elements.

Of course, other locking means can be designed, in particular a system for snapping the gutter onto the closing bar.

Thus, by the various functional and structural technical characteristics above, the Applicant proposes a sound diffusion device allowing attachment to a strap for attaching a pair of swimming goggles or a helmet for a swimmer. a water sport so as not to encumber the practice of the sport and able to be adapted on a variety of models of straps and swimming goggles, helmet or other associated.

detailed description

The present invention will now be described in the following with reference in conjunction to Figures 1 to 8 appended to the description.

As indicated in the preamble to the description, current solutions for fixing an electronic device for water sports are limited to integrating an electronic module into a given model of swimming goggles.

One of the objectives of the present invention consists in allowing the adaptation of such a device to a fastening strap of a pair of spectacles, taking into account the variability of the geometric shapes of the cross section of the fastening strap.

This is made possible in the example described below, which considers use of the device by at least one swimmer wearing a pair of swimming goggles, the swimmer corresponding to the practitioner of the water sport mentioned above.

It will be understood here that this example is not limiting and that the invention will find other applications for fixing accessories on a tether strap under other conditions, for example in the practice of other water sports.

According to the example of FIG. 8, a plurality of devices 1000a, 1000b and 1000c developed within the framework of the present invention are worn by a plurality of swimmers in an aquatic environment 11000, for example a closed aquatic environment of the swimming pool type or an environment open aquatic of the sea type. Devices 1000a, 1000b and 1000c can be designed specifically to be worn over swimmers' swimming goggles and have a structure similar to device 1000 as illustrated in Figure 1.

This device 1000 comprises a hollow and sealed casing 1100, for example a hollow body of rectangular section having an internal face 1110 and an external face 1120 opposite one another. As illustrated in Figures 1 to 4, the inner face 1110 has a flat and smooth surface and is intended to rest in contact with the swimmer's head when the latter is wearing swimming goggles, while the outer face 1120 comprises means removable fixing 1300 of the device 1000 on a fastening strap of a pair of swimming goggles.

In this example, the fixing means 1300 comprise two branches 1310a and 1310b extending from the casing 1100, for example from two opposite side edges of the external face 1120, and curved towards this same external face 1120 so that the two branches 1310a and 1310b and the outer face 1120 form between them a first housing 1330 for receiving the fastening strap.

According to the example of FIG. 4, the free ends 1311a and 1311b of the two branches 1310a and 1310b are arranged facing each other and separated from each other so as to form a first passage slot 1320 opening onto the first reception accommodation 1330.

Optionally, the two branches 1310a and 1310b have an elastic structure arising from their thickness and/or from the selected material allowing them to be deformed slightly and to widen and/or narrow the first passage slot 1320 or even to bring the branches 1310a and 1310b closer together. of the outer face 1120, for example to hold the strap sandwiched between the branches 1310a and 1310b and the outer face 1120.

Preferably, the free ends 1311a and 1311b are separated by a width substantially equal to 3 mm when the two branches 1310a and 1310b are in the rest position, so that a fastening strap of flat or rectangular cross section can be inserted into the first housing 1330 along its width but cannot pass through the first passage slot 1320 along its length. It is also possible to design two branches 1310a and 1310b positioned relative to the outer face 1120 at a maximum distance of approximately 3 mm also so as to prevent any accidental rotation of the strap relative to the device 1000 and to minimize the size associated with the fixing means 1300.

In keeping with the underlying concept of adapting the attachment means 1300 to a plurality of tether strap cross-sections, the first passage slot 1320 can accommodate a closure strip 1340 as illustrated in Figures 1-3 , 5 and 6. Depending on the design, this may partially or punctually obstruct the first passage slot 1320 or extend over its entire length (FIG. 2) in order to prevent the passage of the fastening strap through the first passage slot 1320 independently of their respective dimensions.

According to the example of FIG. 5, the closure strip 1340 has an H-shaped cross-section forming two grooves 1341a and 1341b, each groove 1341a and 1341b being sized to receive a free end 1311a and 1311b of the branches 1310a and 1310b. This design constrains the shutter bar and the device 1000 according to five degrees of freedom, makes it possible to associate and dissociate the shutter bar 1340 from the device 1000 by translation of the shutter bar 1340 along the first slot of passage 1320 and can of course be supplemented by a variety of means making it possible to facilitate or solidify the assembly, for example the inclusion in the grooves 1341a and 1341b and/or on the free ends 1311a and 1311b of the branches 1310a and 1310b d a click system.

In this same example, the closure bar 1340 is provided with a gutter 1350 having two arms 1351a and 1351b whose free ends form a second passage slot 1360 opening onto a second receiving housing 1370. In one design, the gutter 1350 and the closure bar 1340 form a single piece element and the free ends of the two arms 1351a and 1351b have the H-shaped cross section comprising the grooves 1341a and 1341b, which is traversed by the second passage slot 1360. The shape of the second housing 1370 being defined by the shape of the cross section of gutter 1350, it is possible to adapt device 1000 to any form of fastening strap by providing a suitable gutter 1350 without modifying housing 1100. Preferably, gutter 1350 has a circular or oval internal cross-section and the arms 1351a and 1351b have an elastic structure allowing to widen the second fe passage slot 1360 before inserting the blanking strip 1340 fitted with the gutter 1350 in the first passage slot 1320

It is also possible to design a gutter 1350 separate from the closure bar 1340, which is provided with means for receiving the free ends of the arms 1351a and 1351b to facilitate the replacement and exchange of the gutter 1350. In such a design , the cross-section in H is full, which also facilitates its realization.

Optionally, the shutter bar 1340 is provided with locking means in translation, for example locking means forming a one-piece element with a shutter bar 1340 alone or even removable locking means associated with a shutter bar 1340 fitted with a 1350 gutter.

According to the example of Figures 5 and 6, the locking means comprise a locking element 1342 of rectangular section designed to be inserted into two grooves 1352a and 1352b provided on the arms 1351a and 1351b of the gutter 1350 and comprising hand a stop 1342a (Figure 6) preventing any translation, on the other hand a latch 1342b capable of moving from an open position in which the latch 1342b is arranged in the extension of the grooves 1352a and 1352b to a closed position where the latch is arranged substantially perpendicular to the grooves 1352a and 1352b, so as to block the movement of the closure strip 1340, the gutter 1350 and the housing 1100.

The swimmer can thus pass the strap for attaching the swimming goggles into the first receiving housing 1330 or the second receiving housing 1370, insert the closing strip 1340 into the first passage slot 1320 so as to close it or to associate the gutter 1350 with the device 1000 according to the selected reception housing and activate the locking means to ensure the integrity of the device 1000 and its retention on the fastening strap.

Additionally, the hollow box 1100 integrates an electronic module 1200 configured for sound diffusion, for example the electronic module 1200 illustrated in FIG. 7 and comprising a plurality of elements. The elements of the electronic module 1200, for example the elements 1210, 1220, 1230, 1240, 1250 and 1260, individually or in combination, can be integrated into a single electronic circuit, into several integrated circuits and/or into discrete electronic components. The elements of the electronic module 1200 are also selected and arranged relative to each other so as to form a miniaturized electronic module 1200 which can be housed in a waterproof case 1100 with a volume of less than 55cm ³ to ensure minimal bulk for the swimmer .

Thus, the electronic module 1200 comprises first reception means 1210 configured to receive at least one signal containing audio information, for example information coming directly or indirectly from a communication terminal 2000, according to a first wireless communication mode. The electronic module 1200 integrates for example a radio module comprising the first reception means 1210, here a radio receiver, and allowing the reception of a signal according to one or more given radio frequencies.

In this same example, the electronic module 1200 also incorporates a selection circuit 1230 of the first reception means 1210 configured to select the radio frequency on which the first reception means 1210 receive the signal. The selection circuit 1230 is for example configured to scan a specific radio frequency interval and pick up any signal emitted on this radio frequency interval to allow multi-channel listening, the radio frequency interval then corresponding to a first range of communication channels of the first mode of wireless communication.

It is obviously possible to design first reception means 1210 and a selection circuit 1230 suitable for any other wireless communication mode and operating on the same principle. The first wireless communication mode is selected by those skilled in the art taking into account the simplicity of implementation of the first reception means 1210 and of the selection circuit 1230 inside a miniaturized electronic module 1200, of the availability of communication channels associated with the first wireless communication mode and also the communication range.

This same range can also be improved if necessary by arranging a communication antenna on the device 1000. Such a communication antenna is for example fixed on a side face of the housing 1100 so as not to hinder the movements or the swimmer's vision and makes it possible to increase the range of the first means of communication 1210 in a manner adapted to the spatial constraints of the aquatic environment 11000. In the context of radiofrequency communication, the addition of a communication antenna thus makes it possible to reach an effective range of 15 km facilitating communication in an open aquatic environment, for example for swimming in open water.

In addition to the first reception means 1210 allowing the reception of a signal containing audio information, the electronic module 1200 comprises means 1220 for generating an audio transcription of the signal for its broadcast to the swimmer. In the example described above, the generation means 1220 are for example incorporated in the radio module and can comprise additional means configured to filter the noise, adapt the output volume or even select a sound diffusion system. Depending on the design of device 1000, the sound delivery system can be pre-selected to match the means built into device 1000 or adaptable from among a plurality of sound delivery systems according to the swimmer's preferences.

Similarly, the electronic module 1200 can include at least one sound diffusion system incorporated in the generation means 1220 or even comprise a connection port 1240 of an audio amplification system 3000 of the sound diffusion system. Such an audio amplification system 3000 corresponds for example to a pair of in-ear headphones or to a bone diffusion headset connected to a connection port 1240, for example according to a wireless connection or according to a wired connection via an element physical interface elements 1240a, 1240b or 1240c as shown in Figures 1 and 3. Obviously, the physical interface elements 1240a, 1240b and 1240c are designed to allow the connection of the audio amplification system 3000 to the electronic module 1200 ensuring the tightness of each part. It is also possible to design physical interface elements 1240a, 1240b and 1240c designed for the connection of other external elements allowing reloading and/or parameterization of elements 1210, 1220, 1230, 1240, 1250 and/or 1260.

In particular, the electronic module 1200 described in FIG. 7 incorporates a battery 1260 designed to provide sufficient autonomy to the device 1000 for the practice of sports activities, for example autonomy of several hours, while ensuring minimal bulk. Such a battery can for example incorporate a magnetic charging system, for example a “Qi” type wireless charging system and/or be connected to at least one of the physical interface elements 1240a, 1240b and 1240c depending on the compactness of the selected solution, its ease of implementation or its average lifespan.

Optionally, the electronic module 1200 can include other elements that fulfill auxiliary functions facilitating the operation of the first receiving means 1210, the generating means 1220 and/or the control circuit 1230. The electronic module 1200 can thus include second reception means 1250 configured to receive at least one item of information representative of a setting. The information representative of a setting corresponds to any information or command that can impact the operation of the constituent elements of the electronic module 1200. Such a design makes it possible to limit the number of physical interface elements 1240a, 1240b and 1240c necessary while allowing a plurality of device settings including:

- starting, stopping or placing the device on standby; and or

- a change of the communication channel or of the first range of communication channels of the first wireless communication mode; and or

- a change in sound system or sound system volume,
the second receiving means 1250 being configured to control the first receiving means 1210, the generating means 1220 and/or the control circuit 1230 according to the information representative of a setting.

Obviously, the second reception means 1250 are not constrained to the same criteria as the first reception means 1210. If it is therefore possible to design a device 1000 in which the first reception means 1210 and the second reception means 1250 are confused, for example by the transmission of information representative of settings via radio frequency communication, a short-range communication module is provided here suitable for receiving information once the swimmer wearing the device 1000 has left the aquatic environment 11000 , for example before the practice of swimming for a startup and a setting of the device 1000 according to the preferences of the swimmer. This design then makes it possible to avoid any range constraint and to select a second communication mode associated with the second reception means 1250 making it possible in a simple manner to transmit commands, for example a wireless communication mode of the “Bluetooth” type.

According to FIG. 7, provision is made for the signal containing audio information and the at least one representative parameter information both to come from a communication terminal 2000. It is of course possible to provide, in a variant, a plurality of communication terminals 2000 , each being capable of transmitting information to the device 1000 according to a given mode of communication. It is also possible to design a single communication mode allowing both transmissions, as stated above.

As illustrated in FIG. 8, a communication system 10000 is designed here, for example between the swimmers evolving in the aquatic environment 11000 and a trainer aiming to communicate instructions to said swimmers, in which a remote electronic entity 4000 is configured to receive the signal containing audio information according to a third mode of communication and transmitting it according to the first mode of communication. According to this design, the second and third modes of communication can be confused and the communication terminal 2000 can then transmit the signal containing audio information and occasionally the at least one piece of information representative of parameter setting according to the second communication mode only. The selection of a second mode of communication commonly used in the public, in particular a short-range wireless communication mode of the “Bluetooth” type or any other appropriate present or future wireless communication mode, thus makes it possible to access the system 10000 communication device using a personal electronic device such as a smart phone or computer serving as a 2000 communication terminal via a dedicated application or program and facilitating the trainer's interaction with the 10000 communication system.

In this example, the remote electronic entity 4000 includes reception means according to the third communication mode and transmission means according to the first communication mode. In accordance with the communication modes selected in the example above, the remote electronic entity 4000 comprises an electronic module integrating a “Bluetooth” type module in wired communication with a radio module comprising transmission means and therefore allows the conversion of the first signal transmitted at short range by the communication terminal into a second signal received at medium or long range by the sound diffusion devices 1000a, 1000b and 1000c.

In addition to the action of the selection circuit 1230 described above, the communication terminal 2000 can transmit at least one piece of information representative of the command intended for the remote electronic entity 4000 impacting its operation. The electronic entity 4000 can for example transmit the signal containing audio information according to a communication channel selected according to the representative command information and corresponding or not to a communication channel associated with the devices 1000a, 1000b and/or 1000c according to their respective settings. This design then makes it possible to select from the communication terminal 2000 the device(s) 1000a, 1000b and 1000c with which to communicate. It is also possible to design a variety of additional commands transmitted by the communication terminal 2000 to the remote electronic entity 4000 according to their design, in particular start-up, shutdown or standby commands as set out above with regard to second reception means 1250.

Thus, it will be understood that the present invention provides a sound diffusion device capable of being fixed on a fastening strap of a pair of swimming goggles providing stable fastening for a variety of cross-sections of fastening strap and adaptable according to the specific characteristics of the cross-section considered. The sound diffusion device further comprises a miniaturized electronic module capable of being housed in a 55cm ³ sealed box forming the main body of the device to ensure minimal bulk for the practice of swimming while allowing the continuous reception of a signal containing audio information. This device can be included in a communication system comprising several devices in communication with a communication terminal associated with a trainer via a remote electronic entity serving as a gateway.
