Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Reference in the specification to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. Those of skill in the art will explicitly and implicitly appreciate that the described embodiments of the application may be combined with other embodiments.

The following is an exemplary description of an earpiece embodiment for an earpiece.

Referring to fig. 1, an ear 100 of a user may include physiological sites such as an external auditory meatus 101, an concha cavity 102, and an auricle 103. Wherein, although the external auditory canal 101 has a certain depth and extends to the tympanic membrane of the ear 100, for convenience of description, the external auditory canal 101 refers specifically to its entrance (i.e., earhole) away from the tympanic membrane without specific explanation of the present application. The concha chamber 102 has a certain volume and depth, and the concha chamber 102 is in direct communication with the external auditory meatus 101, i.e., the earhole is simply considered to be located at the bottom of the concha chamber 102.

The headphone 1 is an audio transducer capable of receiving an electrical signal emitted from a media player or receiver and converting the electrical signal into a sound wave audible to a user. In some embodiments, the headset 1 may be an open headset, such as an ear-hanging headset, a rear-hanging headset, or an ear-clip headset, etc.

As shown in fig. 2 or 3, the headset 1 may be an ear-hook headset, and in some embodiments, at least part of the headset 1 may be inserted into the concha cavity 102 of a user (user) in a wearing state, so as to improve wearing stability. In some embodiments, the sound emitting portion 20 of the headset 1 may at least partially cover a pinna 103 of a user's ear, such as an antitragus, concha, or triangular fossa (not shown), but not occlude the external auditory canal 101 of the user's ear or otherwise visually occlude the external auditory canal 101 of the user's ear. In some embodiments, the sound emitting portion 20 of the earphone 1 may also fit or abut against the face area in front of the ear of the user, and the side of the sound emitting portion 20 that is used to emit sound is directed towards the ear of the user or towards the external auditory canal 101 of the user.

Further, individual differences may exist for different users, resulting in different shapes, sizes, etc. of the ear 100. For ease of description, and to reduce (or even eliminate) individual differences among different users, a simulator having a HEAD and its (left and right) ears 100, such as GRAS 45BC KEMAR, HEAD diagnostics, B & K4128 series, or B & K5128 series, may be manufactured based on ANSI:S3.36, S3.25, and IEC:60318-7 standards, thereby presenting a scenario in which most users wear the headset 1. Taking GRAS KEMAR as an example, the simulator of the ear 100 may be any of GRAS 45AC, GRAS 45BC, GRAS 45CC, GRAS 43AG, etc., and taking HEAD statistics as an example, the simulator of the ear 100 may be any of HMS II.3, HMS II.3LN, HMSII.3LN HEC, etc. Accordingly, in the present application, descriptions such as "the user wears the headset 1", "the headset 1 is in a worn state", and "in a worn state" may refer to the headset 1 of the present application being worn on the ear 100 of the aforementioned simulator. Of course, because of individual differences among different users, the headset 1 may be worn by different users with a certain difference from the ear 100 of the headset 1 worn by the simulator, but such a difference should be tolerated.

In the fields of medicine, anatomy, etc., three basic tangential planes of a sagittal Plane (SAGITTAL PLANE), a coronal Plane (Coronal Plane), and a Horizontal Plane (Horizontal Plane) of a human body or a human body simulator, and three basic axes of a sagittal Axis (Sagittal Axis), a coronal Axis (Coronal Axis), and a Vertical Axis (Vertical Axis) may be defined. The sagittal plane is a section perpendicular to the ground and is a section perpendicular to the ground, which is formed along the front and rear directions of the body, and the coronal plane is a section perpendicular to the ground and is a section perpendicular to the body, which is formed along the left and right directions of the body, and the coronal plane is a section parallel to the ground and is a section parallel to the body, which is formed along the up and down directions of the body, and which is formed along the up and down directions of the body. Accordingly, the sagittal axis refers to an axis along the anterior-posterior direction of the body and perpendicular to the coronal plane, the coronal axis refers to an axis along the lateral direction of the body and perpendicular to the sagittal plane, and the vertical axis refers to an axis along the superior-inferior direction of the body and perpendicular to the horizontal plane. Further, the term "front side of the ear" as used herein is a concept of "back side of the ear" with respect to the side of the ear facing away from the head and the side of the ear facing toward the head, all for the user or simulator of the ear 100. The ear 100 of the human body or the human body simulator is observed along the direction of the coronal axis, as shown in fig. 1.

As an example, in connection with fig. 2 and 3, the headset 1 may include an ear hook 10 and a sound emitting part 20 connected to each other. In the worn state, the ear hook 10 may be hung between the auricle 103 and the head of the user, i.e., at least part of the ear hook 10 of the headset 1 may be located at the rear side of the ear 100, so that the headset 1 is hung on the ear 100, and the sounding part 20 may be located at the front side of the auricle 103. The sound emitting portion 20 may be a sound playing device, and the sound emitting portion 20 may be used to convert an electrical signal into an acoustic signal (which may also be referred to as "sound waves" or "sound signals") and transmit to the ear 100 of the wearer.

In some embodiments, a battery or circuit board device may be disposed within the earhook 10, or the earhook 10 may be provided with both a battery and a circuit board. Of course, the ear hook 10 may be provided with no device such as a battery or a circuit board, and the device such as a battery or a circuit board may be mounted on the sound emitting unit 20.

In some embodiments, as shown in fig. 1-5, sound emitting portion 20 may include a cartridge housing 210. In some embodiments, as shown in fig. 5, the headset 1 may further include a speaker assembly 30 disposed within the deck housing 210. The speaker assembly 30 is a component that can convert an electrical signal into a corresponding acoustic signal to realize the sound playing function of the sound emitting portion 20. As an example, the speaker assembly 30 may include a bone conduction speaker and a gas conduction speaker, and in other embodiments, the speaker assembly 30 may be configured as one of a gas conduction speaker and a bone conduction speaker.

In some embodiments, as shown in fig. 2-5, the earhook 10 may include a adaptor housing 110 and a hook 120. Wherein adapter housing 110 may be used to connect cartridge housing 210 and hook 120. The hook 120 presents a hook shape for a user to hook onto the user's ear 100 when wearing the headset 1.

As shown in fig. 5 to 7, the adaptor housing 110 may be provided inside with a mounting groove 111. The installation groove 111 may have a first groove wall 1111 and a second groove wall 1112 disposed opposite to each other and an installation opening 1113 between the first groove wall 1111 and the second groove wall 1112, the adaptor housing 110 may be provided with a sound receiving hole 112, and the sound emitting end 1121 of the sound receiving hole 112 is located on the first groove wall 1111.

The headset 1 may further comprise a microphone 40 and a support plate 50, the microphone 40 and the support plate 50 being mounted between the first slot wall 1111 and the second slot wall 1112 via a mounting opening 1113. The support plate 50 is laminated with the microphone 40. And the support plate 50 is located between the microphone 40 and the second groove wall 1112 for pressing the microphone 40 against the first groove wall 1111. The microphone 40 collects sounds outside the headset 1 through the sound receiving hole 112. The sound outside the headset 1 may be, for example, a user speaking sound, a whistling sound, a car bell sound, surrounding human voice, or traffic sounds.

Specifically, the support plate 50 and the microphone 40 are stacked along the arrangement direction of the first slot wall 1111 and the second slot wall 1112, the support plate 50 can press the microphone 40 to the first slot wall 1111, and the microphone 40 can be fixed in the adaptor housing 110 under the pressing action of the support plate 50 and the limiting action of the mounting slot 111. By such arrangement, the microphone 40 can be pressed and fixed on the adapter housing 110 by using a simple structure and elements, so that the assembling difficulty of the microphone 40 in the earphone 1 can be reduced, and the assembling difficulty of the earphone 1 can also be reduced.

In addition, the microphone 40 may directly correspond to the sound receiving hole 112 on the first groove wall 1111, and after the microphone 40 is pressed on the first groove wall 1111, the communication between the sound receiving hole 112 and the inner space of the earphone 1 can be avoided as much as possible, so that the air tightness between the microphone 40 and the sound receiving hole 112 can be improved, and the sound receiving effect of the microphone 40 can be improved.

In some embodiments, the material of the support plate 50 may be metal or rigid plastic. By the arrangement, the supporting plate 50 has certain deformation resistance, and the supporting plate 50 is prevented from being deformed or damaged when being installed and abutted against the microphone 40, so that the holding effect on the microphone 40 is affected, and the air tightness of the earphone 1 is further affected.

In some embodiments, as shown in fig. 5, the headset 1 may include a flexible circuit board 60 and a main control circuit board 70. The main control circuit board 70 may be disposed in the deck housing 210, the mounting opening 1113 may face the main control circuit board 70, and a portion of the flexible circuit board 60 may extend into the mounting slot 111 through the mounting opening 1113 and electrically connect the microphone 40 and the main control circuit board 70.

The main control circuit board 70 refers to a control core portion inside the earphone 1, and the main control circuit board 70 may be a PCB (Printed Circuit Board) circuit board or a FPC (Flexible Printed Circuit board) circuit board. The main control circuit board 70 may be electrically connected to the microphone 40 and the speaker assembly 30, respectively.

The flexible printed circuit board 60 (Flexible Printed Circuit abbreviated as FPC) is a flexible printed circuit board with high reliability and excellent characteristics of high wiring density, light weight, thin thickness and good flexibility, and is usually made of polyimide or polyester film as a base material, also called a flexible circuit board or a flexible circuit board. The flexible circuit board 60 is adopted to connect the microphone 40 and the main control circuit board 70, which is more suitable for the complex internal space of the earphone 1, the flexible circuit board 60 is not easy to damage relative to the common wires, and meanwhile, the good flexibility can enable the flexible circuit board 60 to avoid other elements in the movement shell 210 and the adapter shell 110.

Specifically, the flexible circuit board 60 has one end connected to the main control circuit board 70 in the deck housing 210 and the other end extending into the mounting groove 111 through the mounting opening 1113 to be connected to the microphone 40. By arranging the mounting opening 1113 of the mounting groove 111 towards the main control circuit board 70, one end of the flexible circuit board 60 can be conveniently connected with the main control circuit board 70, and the other end of the flexible circuit board 60 can be conveniently extended into the mounting groove 111 for connection, so that redundancy and folding of the flexible circuit board 60 are reduced, and short-circuit of the flexible circuit board 60 can be reduced.

In some embodiments, the support plate 50, the microphone 40, and a portion of the flexible circuit board 60 achieve an interference fit with the mounting groove 111 in a direction along the separation of the first groove wall 1111 and the second groove wall 1112 such that the microphone 40 is tightly pressed against the first groove wall 1111. In other words, the distance between the first groove wall 1111 and the second groove wall 1112 is less than or equal to the sum of the thicknesses of the support plate 50, the microphone 40, and the portion of the flexible circuit board 60 extending into the mounting groove 111. In this case, the thickness refers to the thickness of each component in the non-mounted state.

By this arrangement, the components in the mounting groove 111 can be abutted more tightly, and the supporting plate 50, the microphone 40 and part of the flexible circuit board 60 can be clamped between the first groove wall 1111 and the second groove wall 1112 more firmly, so as to improve the overall air tightness of the earphone 1.

In some embodiments, as shown in fig. 7 and 9, a dust screen assembly 1114 may be disposed within the mounting slot 111. The dust screen assembly 1114 may be located between the first slot wall 1111 and the microphone 40. The dust-proof net assembly 1114 can be used for isolating dust, particles, water drops and other impurities in the air, so that the dust particles, water drops and other impurities in the air are not easy to enter the adaptor housing 110 and the movement housing 210, and the risk of corrosion or damage to internal components such as the speaker assembly 30 and the main control circuit board 70 is reduced.

In some embodiments, the dust screen assembly 1114 may include steel screens, gauze, insulating cotton sheets, and the like (not shown). Or in other embodiments, the dust screen assembly 1114 may include multiple layers of steel mesh or multiple layers of gauze, etc.

The dust screen assembly 1114 also provides an interference fit with the support plate 50, the microphone 40, and a portion of the flexible circuit board 60 along with the mounting slot 111 and with the mounting slot 111. In other words, the distance between the first groove wall 1111 and the second groove wall 1112 is less than or equal to the sum of the thicknesses of the dust-proof net assembly 1114, the support plate 50, the microphone 40, and the portion of the flexible circuit board 60 that extends into the mounting groove 111. In this case, the thickness refers to the thickness of each component in the non-mounted state.

In some embodiments, a portion of the flexible circuit board 60 may be located between the microphone 40 and the dust screen assembly 1114. The sound emitting end 1121 of the sound receiving hole 112 is communicated with the sound collecting area 41 of the microphone 40, the dust screen assembly 1114, the part of the flexible circuit board 60 and the microphone 40 are pressed on the first groove wall 1111 by the supporting plate 50, so that external sound and air flow are not easy to leak from gaps between the first groove wall 1111 and the dust screen assembly 1114, the part of the flexible circuit board 60 and the microphone 40 in the process of entering the sound collecting area 41 of the microphone 40 through the sound receiving hole 112, and the air flow is prevented from entering the switching shell 110 and the core shell 210 as much as possible, the overall air tightness of the earphone 1 is improved, and meanwhile, the sound receiving effect of the microphone 40 is improved.

In some embodiments, as shown in fig. 9 to 11, the adaptor housing 110 may include a partition plate 113 for forming the mounting groove 111, the second groove wall 1112 may be a side surface of the partition plate 113 facing the mounting groove 111, and a groove 1131 may be provided on the partition plate 113.

Since the microphone 40 and the support plate 50 and other components disposed in the mounting groove 111 are interference fit with the mounting groove 111, the first groove wall 1111 and the second groove wall 1112 are slightly deformed. If the rigidity of the second groove wall 1112 is too high, the mounting becomes difficult, and if the rigidity of the second groove wall 1112 is too low, the deformation of the second groove wall 1112 will be large when components are mounted, and the holding effect of the support plate 50 on the components such as the microphone 40 will be poor. Therefore, by arranging the groove 1131 on the partition 113, the partition 113 where the second groove wall 1112 is located is easier to generate micro deformation, so that components such as the microphone 40 and the support plate 50 can enter the mounting groove 111 more easily, the mounting difficulty of the microphone 40 is reduced, and the mounting and debugging of the size in the process of assembling the earphone 1 can be facilitated, so that the assembling difficulty of the earphone 1 is reduced. At the same time, the spacer 113 can be ensured to have certain rigidity, and the holding effect of the support plate 50 on the components such as the microphone 40 can be ensured.

In some embodiments, as shown in fig. 11, the notches 1132 of the grooves 1131 may be oriented the same as the mounting openings 1113, and the length direction of the grooves 1131 is disposed along the depth direction of the mounting grooves 111, the depth direction of the mounting grooves 111 being perpendicular to the spacing direction between the first groove wall 1111 and the second groove wall 1112. As an example, the depth direction of the mounting groove 111 may be in the direction indicated by the arrow C in fig. 11.

Specifically, since the components such as the microphone 40 and the support plate 50 all enter the mounting groove 111 through the mounting opening 1113 and are further inserted into the mounting groove 111 along the depth direction of the mounting groove 111, an interference fit and mounting with the mounting groove 111 are achieved. While the notch 11 of the groove 1131 and the mounting opening 1113 have the same orientation, which means that the groove 1131 is communicated with the mounting opening 1113, and the length direction of the groove 1131 is set to extend along the depth direction of the mounting groove 111, so that the spacer 113 is easier to deform in the process of mounting the microphone 40 and the support plate 50, and the microphone 40 and the support plate 50 are easier to enter the mounting groove 111.

In the process of debugging and disassembling the microphone 40, the direction in which the microphone 40 and the support plate 50 are taken out of the mounting groove 111 is the direction opposite to the depth direction of the mounting groove 111. Therefore, the length direction of the groove 1131 is set along the depth direction of the mounting groove 111, and the supporting plate 50 can be pushed to be taken out by the groove 1131 in the opposite direction of the depth direction of the mounting groove 111 in the process of debugging and disassembling the microphone 40, so that the microphone 40 and other components can be taken out from the mounting groove 111 conveniently, and the disassembling difficulty of the earphone 1 is reduced.

In some embodiments, after other components such as the microphone 40 are assembled in the mounting groove 111, the mounting opening 1113 may be subjected to dispensing or dripping, and the mounting opening 1113 may be plugged by the glue to further fix the microphone 40 in the mounting groove 111. And the glue may further wrap around the side of the spacer plate 113 facing away from the support plate 50 such that the glue is not easily dropped from the mounting opening 1113 after solidification.

In some embodiments, as shown in fig. 2 to 6, the sound emitting part 20 may have a connection end 220 for connecting the earhook 10 and a free end 230 disposed opposite to the connection end 220, and the sound emitting part 20 has a length direction, a width direction, and a thickness direction orthogonal to each other. Wherein at least a portion of the free end 230 may extend into the concha chamber 102 or against the pinna 103 of the user.

The length direction may be the direction of the spacing of the connecting end 220 and the free end 230. The spacing direction of the connection end 220 and the free end 230 refers to the extending direction of the connection line between the connection end 220 and the free end 230. In some embodiments, the connection end 220 and the free end 230 may be irregularly or regularly arc-shaped, and the extending direction of the connection line between the connection end 220 and the free end 230 may refer to a direction defined by a straight line perpendicular to the parallel tangential plane of two reference points on the connection end 220 and the free end 230 that are farthest from each other. The longitudinal direction may also be defined as a direction in which the movement case 210 approaches or separates from the rear of the head in the wearing state, i.e., a direction defined between a side surface of the sound emitting portion 20 that approaches the rear of the head and a side surface that separates from the rear of the head in the wearing state. As an example, the length direction may be as indicated by arrow X in fig. 2 to 7. In the present specification, the longitudinal direction, the width direction, and the thickness direction of the sound emitting unit 20 are defined by the wearing state, and the coordinate system thereof is based on the sound emitting unit 20, and is independent of three basic axes of the human body, and is not changed by a minute difference generated when the device is worn on the ear of a different user.

The width direction may be defined as a direction in which the deck case 210 approaches or separates from the head top in the wearing state, that is, a direction defined between a side of the sound emitting portion 20 that approaches the head top and a side that separates from the head top in the wearing state. As an example, the width direction may be as indicated by an arrow Y in fig. 3 to 7.

The thickness direction may be a direction in which the sound emitting portion 20 faces or faces away from the auricle 103 in the wearing state. As an example, the thickness direction may be the direction indicated by arrow Z in fig. 2 to 7. The thickness direction Z may be substantially parallel to the vibration direction of the speaker assembly 30 in the sound generating portion 20, and substantially parallel means that the space included angle between the two directions is less than 5 °.

In some embodiments, as shown in fig. 6, the depth direction of the mounting groove 111 may be disposed obliquely with respect to the length direction X. The depth direction of the mounting groove 111 may be as shown by arrow C in fig. 6. In other words, the angle between the depth direction C and the longitudinal direction X of the mounting groove 111 is not equal to 0 °. By arranging the depth direction C of the mounting groove 111 in this way, the accommodating space of the adapter housing 110 can be fully utilized, the space utilization rate is improved, and the size occupied by the mounting groove 111 in the length direction X is reduced, so that the size of the earphone 1 in the length direction X can be reduced, and meanwhile, the mounting opening 1113 can be oriented to the main control circuit board 70.

In some embodiments, at least a portion of the hole segments of the sound receiving holes 112 may exhibit an oblique arrangement relative to the vertical of the first slot wall 1111.

Illustratively, as shown in FIG. 7, at least a portion of the hole segments of the sound receiving hole 112 extend in a direction indicated by the arrow D in FIG. 7, and the first slot wall 1111 extends vertically in a direction indicated by the arrow E in FIG. 7.

Because the sound outlet end 1121 of the sound receiving hole 112 is located on the first groove wall 1111 and is communicated with the sound collecting area 41 of the microphone 40, and the sound outlet end 1121 of the sound receiving hole 112 penetrates through the housing where the first groove wall 1111 is located, at least part of the hole section of the sound receiving hole 112 is arranged to be inclined compared with the vertical direction E of the first groove wall 1111, so that the air flow is blocked and weakened by the inclined hole wall after entering the sound inlet end 1122 of the sound receiving hole 112, and the situation that the air flow directly impacts the microphone 40 after entering the sound inlet end 1122 of the sound receiving hole 112 can be reduced, so that the wind noise is further reduced, and the sound receiving effect of the microphone 40 is improved.

In some embodiments, the inclination angle of the extending direction of at least part of the hole sections of the sound receiving holes 112 with respect to the vertical direction of the first groove wall 1111 may be between 0 ° and 20 °. As an example, the inclination angle of the extending direction of at least part of the hole section of the sound receiving hole 112 with respect to the vertical direction of the first groove wall 1111 may be a value of 5 °,10 °,12 °,15 °, 18 °.

As an example, as shown in fig. 7, the inclination angle of the extending direction D of at least part of the hole segments of the sound receiving holes 112 with respect to the vertical direction E of the first groove wall 1111 may be as shown by the angle α in fig. 7, 5 ° < angle α <20 °.

If the inclination angle of the extending direction D of at least part of the hole section of the sound receiving hole 112 with respect to the vertical direction E of the first slot wall 1111 is equal to 0 °, it is indicated that the extending direction D of the sound receiving hole 112 is parallel to the vertical direction E of the first slot wall 1111, and when the airflow enters the sound inlet end 1122 of the sound receiving hole 112 and then directly passes through the sound outlet end 1121 to impact the microphone 40, the microphone 40 generates a larger noise. If the inclination angle of the extending direction D of at least part of the sound receiving holes 112 relative to the vertical direction E of the first slot wall 1111 is greater than 20 °, the sound receiving holes 112 occupy more space on the adapter housing 110, and the processing difficulty of the sound receiving holes 112 is increased, and meanwhile, the effective sound information is excessively lost.

Therefore, the extending direction D of at least part of the hole sections of the sound receiving hole 112 is set to have an inclination angle between 0 ° and 20 ° relative to the vertical direction E of the first slot wall 1111, so that the air flow is blocked and weakened by the inclined slot wall after entering the sound receiving end 1122 of the sound receiving hole 112, and the air flow impact force of the microphone 40 is reduced, thereby improving the wind noise resistance of the earphone 1, further effectively improving the sound pickup effect of the microphone 40, reducing the occupation space of the sound receiving hole 112 on the adapting housing 110, and facilitating the processing formation of the sound receiving hole 112 on the adapting housing 110.

In some embodiments, the extending direction of all the hole sections of the sound receiving hole 112 may be set to have an inclination angle between 0 ° and 20 ° with respect to the vertical direction of the first slot wall 1111, so that the sound receiving hole 112 is formed on the adaptor housing 110, and the attenuation of the sound receiving hole 112 on the effective sound information can be reduced, so as to ensure the sound receiving effect and the wind noise resisting effect of the microphone 40.

Of course, in other embodiments, the hole segments of the sound receiving holes 112 may have a shape that is partially inclined and partially curved, and the shape of the hole segments in the sound receiving holes 112 is not specifically shown in this embodiment.

In some embodiments, the valid sound information may refer to target information, such as voice information or alert information, etc. In some embodiments, the effective sound information may refer to sound information of a target frequency band, such as sound information with a frequency band of 500 Hz-1 kHz, 1 kHz-2 kHz, or 200 Hz-2 kHz.

In some embodiments, the adaptor housing 110 may be positioned adjacent to the upper earroot of the user in the worn state. In the length direction X, the entrance end 1122 of the sound receiving aperture 112 may be closer to the free end 230 than the exit end 1121 of the sound receiving aperture 112.

Thus, disposing the sound receiving aperture 112 closer to the free end 230 than the sound outlet end 1121 in the length direction X may bring the sound receiving end 1122 closer to the user's mouth, thereby facilitating the microphone 40 to collect the user's sound through the sound receiving aperture 112 to enhance the sound receiving effect of the microphone 40.

In some embodiments, in the width direction Y, the entrance end 1122 of the sound receiving aperture 112 may be farther from the upper root of the ear than the exit end 1121 of the sound receiving aperture 112. Also, because the adapter housing 110 is disposed adjacent to the upper root of the user, positioning the sound receiving aperture 112 such that the sound receiving end 1122 is farther from the upper root of the user than the sound emitting end 1121 in the width direction Y allows the sound receiving end 1122 to be closer to the user's mouth. This facilitates the collection of the user's voice by the microphone 40 through the sound pickup hole 112, thereby enhancing the sound pickup effect of the microphone 40.

In some embodiments, as shown in fig. 11, the earhook 10 may include a soft cover 80, the soft cover 80 may wrap around the adapter housing 110, and the sound receiving aperture 112 may extend into the soft cover 80 and through the soft cover 80.
