With the development of science and technology, the use habits of people on digital products change and the consumption level of entertainment culture improves, and the dependence of people on the in-ear wireless listening devices is higher and higher. In order to meet the various functional requirements of in-ear wireless listening devices, wireless listening devices are correspondingly integrated with a large number of electronic components. Particularly, in the in-ear wireless listening device integrating the communication noise reduction function, the noise reduction function can be realized by adopting a double-microphone noise reduction algorithm. Here, many electronic components, including the two microphones, need to be arranged in the area of the wireless listening device on the side remote from the ear canal of the user.

However, according to the principle of the two-microphone noise reduction algorithm, it is necessary to pick up a noise signal with one of the two microphones and pick up a noise signal and a voice signal with the other, and the two microphones arranged separately can receive sounds having different frequencies and intensity distributions, whereby noise suppression or cancellation can be performed with a difference in such signals. In this case, if the two microphones are spaced too close, the frequency and intensity distributions of the sounds they receive are highly similar, thereby filtering or attenuating the user's voice, resulting in poor speech quality. This leads to a wireless listening device having a large volume, especially at the outer end, if the two microphones are arranged at a large distance.

The structure of the single body for wearing in the left ear of the user in a wireless listening device is only schematically shown in the following figures, however it will be appreciated by the skilled person that a wireless listening device can comprise two single bodies used in pairs worn in the left and right ear of the user, respectively, which are substantially symmetrically configured in structure and not connected to each other by conventional physical wires. For simplicity of description, only the structure of a single wireless listening device will be described with reference to the drawings.

In some embodiments, the wireless listening device includes an acoustic module 100 for implementing a variety of acoustic functions. The acoustic module 100 can be accommodated in the accommodation space formed by the case assembly, and the acoustic module 100 is thereby protected and supported.

In some embodiments, referring to fig. 1, the acoustic module 100 of the wireless listening device includes a control device 130, a charging device 140, a first microphone 181, a second microphone 182, an antenna 160, a battery (not shown), a speaker 190, and a main board 120 integrated with a chip electrically connected to the above components. In these embodiments, the components of the control device 130, the charging device 140, the first microphone 181, the second microphone 182, the antenna 160, etc., which are required to interact with the outside world or which are required to be connected to the outside world (the components on the upper side in the direction shown in fig. 1) are arranged at the outer end of the wireless listening device, i.e., at the end which is remote from the ear canal of the user when the user wears the wireless listening device.

In some embodiments, the motherboard 120 can support one or at least two of the components in the acoustic module 100. In some embodiments, referring to FIG. 1, the motherboard 120 is a rigid motherboard. In some embodiments, the main board is configured as a folding type circuit board or a flexible circuit board. In some embodiments, the Central Processing Unit (CPU) of the wireless listening device is integrated at the motherboard 120. In some embodiments, the motherboard 120 is electrically connected to the components of the acoustic module 100 by printed wires, leads, flying leads, ball-shaped pins, and the like.

The manipulation device 130 has a substantially flat plate shape. In some embodiments, the control device 130 has a planar section parallel to the main board 120. In some embodiments, referring to fig. 1, the control device 130 is configured as a touch pad, so that compared with a mechanical key switch, the user can feel better experience and science and technology, and discomfort caused by pressing the key with force is reduced. In some embodiments, the touch pad may be a device for implementing touch control by changing parameters such as resistance or capacitance of a touch unit on the touch pad through a body part such as a finger, and is different from mechanical control devices such as a mechanical knob or a mechanical switch in that the touch pad does not usually generate visible mechanical motion to implement the operation of the touch pad. In addition to using techniques that vary the parameters of resistance or capacitance, other touch technologies may be used in some embodiments, as long as they enable operation of the touch pad from outside the wireless listening device in the presence of the housing assembly, and in particular, the top cover.

The charging device 140 includes a charging pin 141, and the charging pin 141 can penetrate through a housing assembly of the wireless listening device, so that the wireless listening device can be charged through an end portion of the charging pin 141 exposed to an outer surface of the housing assembly. In the case of a wireless listening device having a top cover, the end of the charging pin 141 exposed to the outer surface of the casing assembly may be higher than, flush with or slightly lower than the top cover upper surface, where the top cover upper surface refers to the surface of the top cover facing away from the acoustic module 100. In some embodiments, referring to fig. 1, the charging pin 141 may be configured as a cylinder having a circular cross-section. In other embodiments, the charging pin may be configured as a cylinder having a non-circular cross-section, wherein the cross-section of the cylinder may be a variety of shapes as a whole, such as a straight line segment, an arc segment, a broken line segment, a curved line segment, and the like. In some embodiments, referring to fig. 1, the charging pin 141 extends in a straight line in its longitudinal direction, here perpendicular to the direction of the handling device 130. In some further embodiments, the charging pin can extend in its longitudinal direction in an arc and/or a fold. In some embodiments, the charging device includes at least one charging pin serving as a positive terminal and at least one charging pin serving as a negative terminal, wherein the respective charging pins may be identically or differently configured in shape and/or size. In some embodiments, referring to fig. 1, the charging pins 141 are supported by a dedicated support member 142, such as a support plate, wherein the support member 142 enables electrical connection of charging pins of the same polarity (e.g., positive or negative) to become an integral part of the current path during charging. In some embodiments, the charging pins are supported by a member with other functions, such as a motherboard of an acoustic module, and electrical connections to charging pins of the same polarity are made. In some embodiments, referring to fig. 1, the charging pin 141 may be rigidly supported, e.g., fixedly mounted, on the support member 142. In some embodiments, the charging PINs may be resiliently supported, for example in the form of POGO PINs (also known as POGO PINs) mounted on a support member, so that the contact is more stable when in contact with the contacts of the charging stand.

In a plane perpendicular to the manipulation device 130, the orthographic projection portions of the manipulation device 130 and the charging pins 141 overlap, thereby achieving a compact layout in a direction perpendicular to the manipulation device 130. In some embodiments, the smallest circumscribed circle of the pattern consisting of the orthographic projection of all the charging pins 141 at least partially overlaps the manipulation device 130 in the plane of the manipulation device 130, thereby achieving a compact arrangement in a direction parallel to the manipulation device 130. The minimum circumscribed circle here can be understood as: in the projection plane, i.e. in the plane of the control device 130, the smallest circle of the outer contour of the pattern, which is composed of the orthographic projections of all the charging pins 141, can be accommodated. It should be noted that, since the charging pins have a three-dimensional structure, the minimum circumscribed circle accommodates the complete planar shape of the orthographic projection of each charging pin, rather than passing through the center of the planar shape of the orthographic projection of the charging pin. Here, in the plane of the manipulation device 130, the minimum circumscribed circle of the orthographic projections of all the charging pins 141 can partially overlap or completely coincide with the manipulation device 130; the minimum circumscribed circle of the orthographic projections of all the charging pins 141 can fall within the range of the manipulation device 130; or the manipulation device 130 falls within the range of the minimum circumscribed circle of the orthographic projection of all the charging pins 141.

Here, in some embodiments, referring to fig. 1, the touch pad 130 is configured with a through hole, and one or at least two of the charging pins 141 can extend from the supporting member 142 thereof through the through hole of the touch pad 130. In some embodiments, the track pad is configured at its edges with a recess recessed towards a central position of the track pad, and one or at least two of the charging pins can extend from its support member through the recess of the track pad. In other exemplary embodiments, the touch pad 130 is not additionally provided with cutouts, for example through holes or recesses, through which the charging pins can pass, and the touch pad 130 has, for example, a circular, oval or similar shape, wherein one or at least two of the charging pins can extend from the support element past the side of the touch pad.

In some embodiments, referring to fig. 2, the shape and size of the manipulation device and the charging device are designed such that the diameter d of the smallest circumscribed circle of the orthographic projection of the manipulation device 130 and the charging pin 141 in the plane of the manipulation device 130 is 5-8 mm. In some preferred embodiments, the diameter d of the smallest circumcircle of the orthographic projection of the manipulation device 130 and the charging pin 141 in the plane of the manipulation device 130 is 5-6 mm. Here, the above-mentioned minimum circumscribed circle may be understood as: in the projection plane, a minimum circumscribed circle of the outer contour of the pattern collectively composed of the outer contour of the manipulation device 130 and the orthographic projection of each charging pin 141 is formed. In other words, the minimum circumscribed circle refers to the smallest circle that can accommodate the outer contour of the pattern composed of the orthographic projections of the manipulation device 130 and all the charging pins 141 in the above projection plane. By means of the above-described design of the operating device and the charging device, a receiving space can be made available for the arrangement of the components such as the first microphone 181, the second microphone 182 and the antenna 160, which will be explained in more detail below, while providing a sufficient operating area for the operating device 130 and achieving an end-side arrangement of the charging device 140, so that the wireless listening device can have a compact and slim design, in particular at its end remote from the ear canal of the user, and therefore the support of the wireless listening device at the ear of the user is optimized, whereby the user wearing comfort is high and it is not easy to fall off.

In some embodiments, the first microphone 181 and the second microphone 182 may be substantially identically constructed. In other embodiments, the first microphone 181 and the second microphone 182 may also be configured differently.

In some embodiments, the height difference between the orthographic projections of the first and second pick-up holes 183, 184 in the plane perpendicular to the manipulation device 130 is 0-2 mm, such as 0.1-1.5 mm. Here, the orthographic projection of the first sound pickup aperture 183 in the plane perpendicular to the manipulation device 130 may be understood as: an orthographic projection of the geometric center of the inlet plane of the first pick-up hole 183 in a plane perpendicular to the manipulating device 130 is provided, wherein the geometric center of the inlet plane of the first pick-up hole 183 is the geometric center of the cross section of the first pick-up hole 183 in the inlet plane, and the inlet plane is the outer surface of the first microphone 181, on which the first pick-up hole 183 is opened. Here, correspondingly, the orthographic projection of the second sound pickup aperture 184 in the plane perpendicular to the manipulation device 130 can be understood as: an orthographic projection of the geometric center of the inlet plane of the second sound pick-up aperture 184 in a plane perpendicular to the manipulating device 130, wherein the geometric center of the inlet plane of the second sound pick-up aperture 184 is the geometric center of the cross-section of the second sound pick-up aperture 184 in the inlet plane, and wherein the inlet plane is the outer surface of the second microphone 182 on which the second sound pick-up aperture 184 is opened. Here, the opening orientations of the first sound pickup hole 183 and the second sound pickup hole 184 are not limited, wherein the first sound pickup hole 183 and the second sound pickup hole 184 may be opened in the same direction or in different directions. The compact arrangement of the components in the acoustic module 100 at the external end of the wireless listening device is facilitated by the above-described layout of the two microphones 181, 182.

Referring to fig. 3, in a plane where the manipulating device 130 is located, the outline of the orthographic projection of the manipulating device 130 and the outer contour of the charging needle 141 have a minimum circumscribed circle, a first connecting line X1 between the orthographic projection of the first sound pickup hole 183 and the center of the minimum circumscribed circle forms an included angle α with respect to a second connecting line X2 between the orthographic projection of the second sound pickup hole 184 and the center of the minimum circumscribed circle, and the included angle α is within a range of 100-140 °. In other words, in the plane where the manipulating device 130 is located, the orthographic projection of the first sound-collecting hole 183 is connected to the center of the minimum circumscribed circle to form a first connecting line X1, the orthographic projection of the second sound-collecting hole 184 is connected to the center of the minimum circumscribed circle to form a second connecting line X2, and the included angle between the first connecting line X1 and the second connecting line X2 is within the range of 100-140 °. In some more preferred embodiments, the included angle α is in the range of 110 to 130 °. Here, the orthographic projection of the first sound pickup aperture 183 in the plane of the manipulation device 130 may be understood as follows: an orthographic projection of an inlet plane geometric center of the first sound pickup hole 183 on a plane where the manipulating device 130 is located, wherein the inlet plane geometric center of the first sound pickup hole 183 is a geometric center of a cross section of the first sound pickup hole 183 in the inlet plane, and the inlet plane is an outer surface of the first microphone 181, on which the first sound pickup hole 183 is opened. Here, correspondingly, the orthographic projection of the second sound pickup aperture 184 in the plane of the operating device 130 can be understood as follows: an orthographic projection of the geometric center of the inlet plane of the second sound pick-up aperture 184 on the plane of the manipulating device 130, wherein the geometric center of the inlet plane of the second sound pick-up aperture 184 is the geometric center of the cross section of the second sound pick-up aperture 184 on the inlet plane, and wherein the inlet plane is the outer surface of the second microphone 182 on which the second sound pick-up aperture 184 is opened. Here, the opening orientations of the first sound pickup hole 183 and the second sound pickup hole 184 are not limited, wherein the first sound pickup hole 183 and the second sound pickup hole 184 may be opened in the same direction or in different directions. By virtue of the design of the two microphones 181, 182 relative to each other and relative to the charging device 140 and the steering device 130, the wireless listening device can on the one hand have a compact and slim construction at its end remote from the ear canal of the user.

In some embodiments, referring to fig. 1, the antenna 160 is configured as a sheet of metal that extends in an arc. In some embodiments, the metal sheet forming the antenna can be supported, for example, on the motherboard 120 or at a component constituting the housing assembly, such as the top cover 300. In some embodiments, the antenna is configured as a metal trace formed at an inside surface of a component in the housing assembly, such as the top cover 300.

In some embodiments, referring to fig. 5, the housing assembly of the wireless listening device includes a housing 200 and a cap 300 closing a receiving cavity 201 of the housing 200 at an end of the wireless listening device. So that a receiving space for receiving the acoustic module 100 of the wireless listening device is formed by the housing 200 and the top cover 300 which are connected with each other. In some embodiments, the cap 300 and the housing 200 are connected to each other in a snap-fit or like form-fit manner and/or an interference fit manner and/or by means of an adhesive and/or by means of a separate connecting member.

In some embodiments, the housing 200 additionally matches the user's cymba concha or a portion of a cymba concha. Therefore, the wireless listening device is not easy to fall off, and cannot cause local oppression to the ears of a user, so that the wearing comfort is improved.
