Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, an embodiment of the present invention provides an electronic device, which may include:

a first speaker 001 arranged such that a sound emitting direction is a first direction;

a second speaker 002 arranged so that the sound emitting direction is a second direction;

wherein the axes of the first speaker 001 and the second speaker 002 coincide, and the first direction is directed to a fixing surface of the electronic device or the opposite direction of the first direction is directed to the fixing surface of the electronic device, so that the sound of the first speaker 001 is transmitted to a plurality of directions perpendicular to the first direction; the second direction is the same as or opposite to the first direction so that the sound of the second speaker 002 is propagated to a plurality of directions perpendicular to the second direction.

The plurality of directions perpendicular to the second direction may be 360 degrees perpendicular to the second direction, and similarly, the plurality of directions perpendicular to the first direction may be 360 degrees perpendicular to the first direction.

Specifically, the fixing surface of the electronic device may be a surface of the electronic device for fixing itself, and preferably, the fixing surface of the electronic device is a top surface, a bottom surface, or a side surface of the electronic device, for example: the electronic equipment is placed on the ground or a desktop, and the bottom surface of the electronic equipment is a fixed surface of the electronic equipment; the electronic equipment is hung on the roof through the fixing line, and the top surface of the electronic equipment connected with the fixing line is a fixing surface of the electronic equipment; the electronic equipment is installed on the wall through the side, and then this side of electronic equipment is the stationary plane of electronic equipment. For convenience, fig. 1 illustrates the fixing surface as an example of the bottom surface of the electronic device.

When the first direction is directed to the fixed surface of the electronic device, part of the sound output by the first speaker 001 is transmitted to the fixed surface, and the sound is reflected by the fixed surface to the direction opposite to the first direction and the directions perpendicular to the first direction for propagation, and the sound propagated in the directions perpendicular to the first direction is the same, so that the user can obtain the same listening effect in all directions perpendicular to the first direction. When the second direction is directed to the fixed surface of the electronic device, the sound propagation process of the second speaker 002 is the same as that of the first speaker 001, and is not described in detail.

Since the sound emitting direction is directed to the fixing surface of the electronic device, a plurality of directions perpendicular to the sound emitting direction will be parallel to the fixing surface of the electronic device and will not be blocked by the fixing surface any more.

The verticality, the axis coincidence, the same direction, the opposite direction and the like in the embodiment of the invention are not limited to the absolute verticality, the absolute axis coincidence, the same absolute direction, the opposite absolute direction and the like in the mathematical sense. It will be appreciated that due to factors such as process levels, environmental factors, manufacturing requirements, etc., absolute verticality in a mathematical sense, absolute axis coincidence, the same absolute orientation, opposite absolute orientation, etc. may not be achievable. Specifically, the directions of the directions perpendicular to each other, the axes coincident with each other, the directions identical to each other, and the directions opposite to each other according to the embodiments of the present invention may be approximately perpendicular to each other, approximately axes coincident with each other, approximately the same direction, and approximately the directions opposite to each other.

In practical applications, the specific determination criteria for the above "approximation" may be different, such as: and when the included angle between the axis of the first loudspeaker and the axis of the second loudspeaker is smaller than or equal to 15 degrees, determining that the axis of the first loudspeaker is coincident with the axis of the second loudspeaker. Of course, it may also be determined that the axis of the first speaker coincides with the axis of the second speaker when the distance between the axis of the first speaker and the axis of the second speaker is 5 mm or less or 10% or less of the speaker diameter.

When the first direction is opposite to the fixed surface of the electronic device, part of the sound output by the first loudspeaker 001 is transmitted to the opposite surface of the fixed surface, and the sound is reflected to the first direction and a plurality of directions perpendicular to the first direction through the reflection action of the opposite surface to be transmitted, and the sound transmitted in the plurality of directions perpendicular to the first direction is the same, so that the user can obtain the same listening effect in all directions perpendicular to the first direction. Wherein, on the bottom surface of the electronic device, the fixed surface may be the top surface of the electronic device; correspondingly, when the fixed surface is the top surface of the electronic device, the opposite surface can be the bottom surface of the electronic device; when the fixing surface is a side surface of the electronic device, the opposing surface may be another side surface opposing the side surface. When the second direction is opposite to the fixed surface of the electronic device, the sound propagation process of the second speaker 002 is the same as that of the first speaker 001, and the description thereof is omitted.

The axes of the first speaker and the second speaker are coincident, so that the first speaker 001 and the second speaker 002 are arranged in the same direction when the first direction is the same as the second direction, as shown in fig. 2; when the first direction is opposite to the second direction, the first speaker 001 and the second speaker 002 are arranged in opposite directions, as shown in fig. 3. The arrows in fig. 2 and 3 indicate the sound emitting direction. Of course, in other embodiments of the present invention, the positions of the second speaker 002 and the first speaker 001 shown in fig. 2 and 3 may be exchanged, and the present invention is not limited herein.

Since the first speaker 001 and the second speaker 002 are coaxial, the vertical distance from any point around the first speaker 001 and the second speaker 002 to the straight line corresponding to the sound emitting direction of the first speaker 001 and the second speaker 002 is the same, and the sound transmission balance can be further improved. As for any points, the user can obtain the same sound at any of the points as long as the vertical distances of the points from the straight lines corresponding to the sound emitting directions of the first speaker 001 and the second speaker 002 are the same.

Alternatively, the frequency range of the first speaker 001 may be a first range, and the frequency range of the second speaker 002 may be a second range, and the upper frequency limit in the first range is smaller than the upper frequency limit in the second range.

Such as: when a sound having a frequency in the range of (0Hz, 500 Hz) is called a bass sound, a sound having a frequency in the range of (500Hz, 5000 Hz) is called a treble sound, and a sound having a frequency in the range of (5000Hz, 20000 Hz) is called a treble sound, the first range may be (0Hz, 500 Hz), the second range may be (500Hz, 5000 Hz) or (5000Hz, 20000 Hz), and similarly, the first range may be (500Hz, 5000 Hz), and the second range may be (5000Hz, 20000 Hz).

Further, the first speaker 001 may be a low frequency speaker, and the second speaker 002 may be a high frequency speaker.

In other embodiments of the present invention, the first speaker 001 and the second speaker 002 may be disposed above each other, and specifically, the first speaker 001 may be located above the second speaker 002, or the second speaker 002 may be located above the first speaker 001.

As shown in fig. 1, in another embodiment of the present invention, a first cavity 003 may be disposed between the first speaker 001 and the second speaker 002.

It can be understood that the sound emitted by the speaker can be transmitted to the outside of the electronic device through the cavity, and meanwhile, the sound wave phenomenon such as interference is generated by the sound in the cavity through reflection, so that the sound effect of the sound transmitted to the outside of the electronic device can be improved.

Of course, the first cavity 003 may be the entire space or a part of the space of all the spaces between the first speaker 001 and the second speaker 002.

When the first direction is opposite to the second direction, the first speaker 001 and the second speaker 002 are disposed opposite to each other, and the first speaker 001 and the second speaker 002 may share the first cavity 003. Of course, in other embodiments of the present invention, the first cavity 003 may be divided into two sub-cavities, and one of the sub-cavities is used for the first speaker 001 and the second speaker 002.

If the first direction is the same as the second direction, if the speaker relatively close to the fixing surface of the electronic device is referred to as the second speaker 002 and the speaker relatively far from the fixing surface of the electronic device is referred to as the first speaker 001, the sound of the first speaker 001 will be transmitted in the first cavity 003 because the first speaker 001 and the second speaker 002 are arranged in the same direction and the axes of the first speaker and the second speaker are overlapped with each other, and thus the sound emitting direction of the first speaker 001 faces the second speaker 002. Optionally, a second cavity 004 may be disposed between the second speaker 002 and the fixing surface of the electronic device. In this way, sound from the second speaker 002 will be transmitted within the second cavity 004. Of course, if the sound emitting direction of the second speaker 002 is directed towards the first speaker 001, the sound of the second speaker 002 will be transmitted in the first cavity 003. Optionally, a second cavity 004 may be disposed between the first speaker 001 and the fixing surface of the electronic device. Thus, sound from the first speaker 001 will be transmitted within the second cavity 004.

Of course, the second cavity 004 may be all or part of the space between the second speaker 002 and the fixing surface of the electronic device.

Specifically, the heights of the first cavity 003 and the second cavity 004 may be the same or different, and preferably, the height of the first cavity 003 may be greater than the height of the second cavity 004, or the height of the second cavity 004 may be greater than the height of the first cavity 003.

When the upper frequency limit of the frequency range of the first speaker 001 is smaller than the upper frequency limit of the frequency range of the second speaker 002, the height of the cavity used for the first speaker 001 may be larger than the height of the cavity used for the second speaker 002. Namely: when the first speaker 001 is disposed above the second speaker 002, the height of the first cavity 003 is greater than the height of the second cavity 004 between the second speaker 002 and the fixing surface of the electronic device.

It will be appreciated that low frequency sound will produce better bass resonance in the higher cavity, while high frequency sound will be attenuated more with transmission path than low frequency sound, so that the lower cavity will reduce attenuation of high frequency sound.

In other embodiments of the present invention, as shown in fig. 1, a first protrusion 005 may be disposed in the first cavity 003, and a second protrusion 006 may be disposed in the second cavity 004.

The protruding direction of the protrusion is opposite to the sound emitting direction of the loudspeaker using the cavity where the protrusion is located, so that sound output by the loudspeaker can be dispersed by the protrusion, and can be easily dispersed to a plurality of directions vertical to the sound emitting direction of the loudspeaker, and the sound effect is improved.

Specifically, when the first speaker 001 uses the first cavity 003 and the second speaker 002 uses the second cavity 004, the first protrusion 005 may cause the sound of the first speaker 001 to be radiated to a plurality of directions perpendicular to the first direction through the first protrusion 005; the second protrusion 006 may make the sound of the second speaker 002 disperse through the second protrusion 006 in a plurality of directions perpendicular to the second direction.

Alternatively, the first protrusion 005 and the second protrusion 006 may have a circular cross section parallel to the fixing surface, so that the intensity of sound dispersed in a plurality of directions perpendicular to the sound emitting direction of the speaker is uniform, and sound can be more effectively dispersed in a plurality of directions perpendicular to the sound emitting direction of the speaker by the protrusions. Of course, in other embodiments of the present invention, the sound may be transmitted to a plurality of directions perpendicular to the sound emitting direction of the speaker without the above-mentioned protrusion, and the present invention is not limited herein.

Further, when the upper frequency limit of the frequency range of the first speaker 001 is smaller than the upper frequency limit of the frequency range of the second speaker 002, and the first speaker 001 uses the first cavity 003 and the second speaker 002 uses the second cavity 004, the ratio of the bottom sectional diameter to the protrusion height of the second protrusion 006 may be smaller than the ratio of the bottom sectional diameter to the protrusion height of the first protrusion 005.

When the ratio of the bottom cross-sectional diameter to the protrusion height of the second protrusion 006 may be smaller than the ratio of the bottom cross-sectional diameter to the protrusion height of the first protrusion 005, it means that the second protrusion 006 is more "arched" with respect to the first protrusion 005. In this case, the relatively high frequency sound signal will contact the second protrusion 006 within a shorter distance and be reflected to the outside of the electronic device, further reducing the attenuation of the relatively high frequency sound signal.

Wherein, the second protrusion 006 may be disposed at the bottom or the top of the electronic device.

Preferably, as shown in fig. 1, the first protrusion 005 may be a spherical protrusion, and the second protrusion 006 may be a conical protrusion. It will be appreciated that the conical projections facilitate more dispersion of sound and therefore allow better diffusion of relatively high frequency sound in directions perpendicular to the direction of sound output. Since the directivity requirements of relatively low frequency sounds are low, a spherical protrusion may be used.

According to the electronic equipment provided by the embodiment of the invention, the sound emitting direction of the loudspeaker or the reverse direction of the sound emitting direction points to the fixed surface of the electronic equipment, so that the sound of the loudspeaker is uniformly transmitted in a plurality of directions vertical to the sound emitting direction, and the uniformity of sound transmission is improved. Meanwhile, the sound emitting directions of the two loudspeakers in the electronic equipment provided by the embodiment of the invention are coaxial, so that the uniformity of sound transmission can be further improved.

Further, as shown in fig. 1, an electronic device provided in an embodiment of the present invention may further include: the third cavity 007, the third cavity 007 may be in communication with the outside air through a duct 008.

Alternatively, the third cavity 007 may be disposed above the first speaker 001.

Of course, the third cavity 007 may be all or part of the space between the first speaker 001 and the top surface of the electronic device.

Wherein the first opening of the duct 008 faces the first speaker 001, the second opening of the duct 008 communicates with the outside air, and the direction of the first opening is perpendicular to the direction of the second opening.

When the vibrating diaphragm of the loudspeaker works, the vibrating diaphragm can continuously move back and forth to push air, so that vibration is transmitted to ears of a person, and the person can hear sound. Both the front and the rear of the loudspeaker vibrate, and if the vibration of the loudspeaker in the rear direction is also utilized, sound waves are strengthened, and the sound effect is improved.

Wherein the first opening may be higher than the second opening, as shown in fig. 1.

Preferably, the electronic device may further include: the first shell 008 is provided with a first recess 009 on a side wall of the first shell 008, and a bottom of the first recess 009 is connected with the pipe 008 to form an opening, namely a second opening. Alternatively, as shown in fig. 1, the radian of the upper side wall 010 of the first recess 009 is larger than that of the lower side wall 011 of the first recess 009. Through the arrangement, the first recess 009 has the functions of reducing wind noise and improving sound purity. When the first opening is higher than the second opening, the transmission angle of the sound transmitted to the outside of the electronic device through the duct 008 is an angle inclined downward, and since the radian of the upper sidewall 010 of the first recess 009 is larger than the radian of the lower sidewall 011 of the first recess 009, when the sound wave obliquely comes out downward from the second opening, the sound wave is less disturbed by the sidewall of the first recess 009, so that wind noise can be reduced, and the sound purity can be improved.

In the present invention, the first speaker 001 is operated to vibrate the air in the third cavity 007 accordingly. Since the first opening of the duct 008 faces the first speaker 001, part of the sound in the third cavity 007 may be transmitted into the duct 008 to be transmitted to the outside of the electronic device through the duct 008.

Specifically, the duct 008 may be an inverter tube for changing a phase of sound.

Since the phase of the sound wave in the third cavity 007 above the first speaker 001 is opposite to the phase of the sound wave in the first cavity 003 below the first speaker 001, the phase of the sound wave in the third cavity 007 can be changed through the inverter tube, so that the phase of the sound wave in the third cavity 007 when being transmitted to the outside of the electronic device through the inverter tube is close to or the same as the phase of the sound wave in the first cavity 003 below the first speaker 001, thereby avoiding the generation of destructive interference and improving the radiation efficiency of the speaker. When the first speaker 001 is a low frequency speaker, the inverter tube also has a bass compensation function.

Optionally, as shown in fig. 4, another electronic device provided in an embodiment of the present invention may further include: a second case 012, the second case 012 may be provided with a plurality of first type sound transmitting holes 013 at the first cavity 003, and the second case 004 may be provided with a plurality of second type sound transmitting holes 014. Optionally, the area of the second type sound transmitting hole 014 is larger than the area of the first type sound transmitting hole 013. The second housing 012 may be disposed outside the first housing 008.

By providing the sound transmitting holes in the second housing 012, the sound in the cavity can be transmitted to the outside of the electronic device through the sound transmitting holes. Since the relatively high-frequency sound has a weak penetrating power, the area of the sound transmission hole for transmitting the relatively high-frequency sound can be large.

The second case 012 may be provided with a plurality of third type sound transmitting holes 015 at the first recess 009 such that the sound transmitted in the duct 008 is transmitted to the outside of the electronic device through the third type sound transmitting holes 015.

As shown in fig. 5, another electronic device provided in the embodiment of the present invention may further include: a first microphone set 016 and a second microphone set 017, and the microphones in the dotted circle shown in fig. 5 are the microphones in the first microphone set 016; the microphone within the smaller dashed circle shown in fig. 5 is the microphone within the second group 017 of microphones.

The first group of microphones 016 includes at least three microphones, the second group of microphones 017 includes at least one microphone,

the microphones in the first microphone set 016 are arranged on the circumference of a circle at equal intervals, and the microphones in the second microphone set 017 are symmetrically distributed relative to the circle center corresponding to the circumference of the first microphone set 016.

It can be understood that the sound signals in all directions can be better collected through the two microphone groups.

Optionally, the number of microphones in the second microphone group 017 is not less than 2.

The microphones of the second microphone set 017 may be arranged at equal intervals linearly at two sides of the center of a circle, and further, the microphones of the second microphone set 017 may be arranged on the diameters corresponding to the circumferences where the microphones of the first microphone set 016 are located.

Specifically, as shown in fig. 5, two microphones in the first microphone set 016 may be disposed on a straight line formed by the microphones in the second microphone set 017.

Optionally, the first microphone set 016 includes six microphones, and the second microphone set 017 includes two microphones.

Specifically, the first microphone set 016 and the second microphone set 017 may be both disposed on the upper portion of the electronic device, and a plane where the first microphone set 016 and the second microphone set 017 are located is parallel to a top plane of the electronic device.

As shown in fig. 1, in the electronic device according to the embodiment of the present invention, the first speaker 001 and the second speaker 002 are disposed at the lower portion of the electronic device, and the first microphone group and the second microphone group are disposed at the upper portion of the electronic device, so that a larger distance is provided between the speakers and the microphones, and the influence of the speakers on the microphone is reduced.

Meanwhile, the loudspeaker is arranged at the lower part of the electronic equipment, so that the gravity center of the electronic equipment is lower, and the stability is improved. Further, the present invention further lowers the center of gravity of the electronic apparatus by providing the third cavity above the first speaker 001.

Specifically, a first sound insulation layer may be disposed above the first microphone set 016 and the second microphone set 017, a second sound insulation layer may be disposed below the first microphone set 016 and the second microphone set 017, and the first sound insulation layer is provided with a plurality of sound transmission holes corresponding to respective microphones of the first microphone set 016 and the second microphone set 017. Specifically, the first and second soundproof layers may be soundproof cotton.

The second soundproof layer can make the first speaker group 016 and the second speaker group 017 less likely to collect the lower sound (such as the sound emitted from the first speaker 001 and the second speaker 002). The first soundproof layer having the sound through hole allows the above sound to be transmitted to the first microphone set 016 and the second microphone set 017 through the sound through hole, reducing noise interference.

As shown in fig. 1, another electronic device provided in an embodiment of the present invention may further include: an annular lamp 018 is provided in an upper portion of the electronic apparatus.

The annular lamp 018 may be an LED lamp, and specifically, the annular lamp 018 may be formed by a plurality of LED lamps, for example, 12.

As shown in fig. 1 and fig. 4, a light-permeable ring 019 may be disposed above the annular lamp 018, and the lamp tubes of the annular lamp 018 may transmit light through the light-permeable ring 019, so as to improve the light effect of the annular lamp 018.

Optionally, the outer edge of the circular ring 019 may be tilted upward, so that the outer edge of the circular ring 019 generates a light gathering effect, and a high visual sensation is brought to a user.

As shown in fig. 1 and fig. 4, another electronic device provided in an embodiment of the present invention may further include: the cone-shaped input device 020 is arranged on the top of the electronic equipment, and the area of the upper surface of the input device 020 is larger than that of the lower surface of the input device 020.

The cone-shaped input device 020 is arranged on the top of the electronic equipment, and the small end of the input device is downward, and the large end of the input device is upward, so that the input device 020 has a floating effect.

Specifically, the input device 020 may include: a key, a rotary ring, the first microphone set 016 and the second microphone set 017.

Wherein, the button can be 1 and be located input device top surface center, and it is simple to control. Specifically, the key can be operated in two modes of clicking and long-time pressing.

The electronic device provided by the embodiment of the invention also comprises: a processor which can perform various processes according to the operation of the key. For example: when a user presses the key for two seconds, the processor controls the electronic equipment to enter a mute mode, and the loudspeaker does not make sound any more; in the mute mode, if the user presses the key, the processor controls the electronic equipment to push out the mute mode, and the loudspeaker can make a sound normally.

Of course, the user can also control the electronic device to be powered on and off through the key. Such as: when the electronic equipment is in a power-off state, the electronic equipment is powered on when a user clicks a key. When the electronic equipment is in a power-on state, if a user presses the key for more than four seconds, the electronic equipment is powered off. Of course, the user can also control the electronic device to enter or leave the sleep mode through the key.

The swivel in the present embodiment of the invention may surround the outside of the upper surface of the input device 020 and may rotate around the upper surface of the input device 020. The swivel can be used to control the volume of the speaker, e.g., the volume of the speaker increases when the swivel is rotated to one side and decreases when the swivel is rotated to the other side.

Specifically, the first microphone set 016 and the second microphone set 017 in the present invention can be disposed below the upper surface of the input device 020 and attached to the upper surface of the input device 020, so as to facilitate sound collection.

The electronic device provided by the embodiment of the invention can further comprise: and the digital multi-stage frequency dividing circuit is electrically connected with the first loudspeaker 001 and the second loudspeaker 002, and is used for dividing the frequency of the sound signals with different frequencies and sending the sound signals to different loudspeakers for output. The digital multi-order frequency division circuit can better realize frequency division, avoids the phenomena of instantaneous sound breaking and the like, and has the advantage of keeping the volume controllable when the volume is large.

Of course, in other embodiments of the invention, the ring shaped light 018 may be arranged below said input means 020. A light permeable ring 019 may also be arranged below the input means 020.
