[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same components are designated by the same reference numerals, and redundant explanations will be omitted.

[0011] First, an overview of the microphone device 1 in each embodiment will be described with reference to Fig. 1. Fig. 1 is a schematic diagram of the microphone device 1 (2 to 7). The microphone device 1 is wirelessly connected to a communication device 200 mounted on an imaging device 100, and transmits audio data such as the voice of a user 400 and ambient sounds to the communication device 200 via wireless communication. The communication device 200 is electrically connected to the imaging device 100, and transmits audio data received from the microphone device 1 to the imaging device 100. The imaging device 100 stores the audio data received from the communication device 200 in a storage medium provided inside. This makes it possible to store audio data acquired from the microphone device 1 in the imaging device 100.

[0012] The microphone device 1 is intended to be held in the hand of a user 400 or attached to clothing using a holder such as a clip, and the microphone element 10 and substrate, which will be described later, are stored inside the housing 50 of the microphone device 1.

[0013] Each example will be described in detail below. [Example]

[0014] First, a microphone device 1 according to a first embodiment of the present invention will be described with reference to Fig. 2. Fig. 2 is a cross-sectional view of the microphone device 1 according to the first embodiment. As shown in Fig. 2, the microphone device 1 includes a microphone element 10, a wiring 20, a first member 30, a second member 40, and a housing 50. The microphone element 10, the wiring 20, the first member 30, and the second member 40 are housed inside the housing 50.

[0015] The microphone element 10 is covered with a first damping member 70 (described later) and is held to the housing 50 via the first damping member 70. The first damping member 70 is an elastic member such as natural rubber, silicone rubber, or sponge. The housing 50 has a substantially rectangular parallelepiped outer shape. A holding portion (holding member) 50c having a rib-like internal shape extending toward the center of the housing 50 (the -X-axis direction in FIG. 2) is provided substantially perpendicularly on the inner side surface 50a of the housing 50. That is, the holding portion 50c is a rib extending substantially perpendicularly from the inner side surface 50a of the housing 50. The holding portion 50c is provided with a connecting portion 50d protruding in the Z-axis direction. The first member 30 and the second member 40 are fixed to the connecting portion 50d with screws (not shown), respectively, to determine their positions relative to the housing 50.

[0016] The first member 30 and the second member 40 are each an electronic substrate having a substantially plate shape. At least one of the first member 30 and the second member 40 is electrically connected to the wiring 20 described below. The main surfaces of the first member 30 and the second member 40 are held by the holding portion 50c so that they are substantially perpendicular to the thickness direction (Z-axis direction) of the housing 50. As a result, the first member 30 and the second member 40 are arranged substantially parallel to each other at positions separated from each other in the Z-axis direction due to the difference in height of the connecting portion 50d. This difference in height forms a space 60 between the first member 30 and the second member 40. The microphone element 10 and the wiring 20 are electrically connected.

[0017] One end of the wiring 20 penetrates a portion of the first damping member 70 covering the microphone element 10 and is connected to the microphone element 10. The other end of the wiring 20 (the end opposite to the end connected to the microphone element 10) is electrically connected to either the first member 30 or the second member 40. A portion of the wiring 20 is stored in a bent state inside a space 60 formed between the first member 30 and the second member 40. The wiring 20 comes into contact with both the first member 30 and the second member 40 due to a repulsive force generated when the wiring 20 is bent. In this way, the microphone device 1 is configured so that the wiring 20 does not come into direct contact with the housing 50.

[0018] Next, how noise is transmitted when the wiring 20 is in contact with the housing 50 and when it is not in contact with the housing 50 will be described together with the usage state of the microphone device 1.

[0019] The microphone element 10 converts the picked-up sound into an electrical signal and sends the signal to the electronic board, which is either the first member 30 or the second member 40, via the wiring 20. The electronic board converts the electrical signal sent from the microphone element 10 into audio data and stores it in a storage medium inside the electronic board or transmits the audio data to the communication device 200.

[0020] If the user 400 attempts to operate the microphone device 1 while recording audio data, the user 400 will touch an operation unit (not shown) provided on the outermost surface of the microphone device 1. At this time, the user 400 touches or grips the housing 50 of the microphone device 1, which applies a force such as a shock propagation or deformation to the microphone device 1. Furthermore, movements such as walking, running, or jumping by the user 400 while recording audio data may be transmitted to the microphone device 1 as vibrations.

[0021] If the wiring 20 were in contact with the inner side surface 50a of the housing 50, touch noises generated when the user 400 touches the housing 50 or vibrations generated by the user's movement would be transmitted directly to the wiring 20. Furthermore, if the user 400 grips the housing 50 and the shape of the housing 50 is deformed, the contact state of the wiring 20 in contact with the inner side surface 50a of the housing 50 would change, and this could be recorded as a rubbing sound. Thus, if the wiring 20 were in direct contact with the inner side surface 50a of the housing 50, the disturbances caused by the user's operation could be recorded as mechanical noise or other noise.

[0022] On the other hand, in the microphone device 1 of the present embodiment, the wiring 20 is not in direct contact with the inner side surface 50a of the housing 50. This lengthens the propagation path from the housing 50 to the wiring 20, making it possible to reduce noise. Also, the wiring 20 and the components in contact with the wiring 20 (the first member 30 and the second member 40) are each separated from the inner side surface 50a of the housing 50 (are not in contact with the inner side surface 50a), making it possible to suppress the propagation of force.

[0023] Next, other functions of the microphone device 1 of this embodiment will be described. In the microphone device 1, the positions of the first member 30 and the second member 40 relative to each other in the height direction are determined by the height (length in the Z-axis direction) of the connection portion 50d provided on the holding portion 50c. As a result, even if a force is applied in the Z-axis direction by the user 400 gripping the housing 50, the force does not propagate beyond the holding portion 50c, and therefore the relative positions of the first member 30 and the second member 40 in the height direction do not change. Since the relative positional relationship between the first member 30 and the second member 40 and the wiring 20 is maintained, the contact state between them does not change, and therefore noises such as scraping or creaking can be reduced.

[0024] In the microphone device 1, the space 60 is a portion of the internal space of the housing 50 that includes approximately the center of the housing 50 in the thickness direction (Z-axis direction). The approximately center of the thickness direction of the housing 50 is a position physically separated from the outermost surface of the housing 50, and the wiring 20 and intervening components that hold the wiring 20 are disposed around this position. These intervening components lengthen the force transmission path from the outermost surface of the housing 50 to the wiring 20, thereby reducing the stress applied to the wiring 20. Preferably, the length L1 of the space 60 in the thickness direction of the housing 50 is 75% or less of the length L2 of the internal space of the housing 50. More preferably, the length L1 is 50% or less of L2.

[0025] Furthermore, in the microphone device 1, the microphone element 10 is covered with the first damping member 70 and is held in the housing 50 via the first damping member 70. Because the microphone element 10 is covered with the first damping member 70, vibrations or impacts transmitted to the microphone element 10 and the wiring 20 from the exterior surface of the housing 50 can be suppressed.

[0026] Furthermore, in the microphone device 1, at least one of the first member 30 or the second member 40 is made of a material having higher rigidity than the housing 50. By using a material having higher rigidity than the housing 50 for at least one of the first member 30 or the second member 40, the rigidity can be increased toward the interior of the microphone device 1. As a result, even if the user 400 applies a strong force to the microphone device 1, the force caused by deformation of the housing 50 can be absorbed by the first member 30 or the second member 40, thereby suppressing the force applied to the wiring 20. In this way, by increasing the strength of the first member 30 or the second member 40, deformation of the housing 50 can be suppressed, and abnormal sounds (noises) such as rubbing or creaking of the wiring 20 can be reduced. [Example]

[0027] Next, a microphone device 2 according to a second embodiment of the present invention will be described with reference to FIGS. 3(a) and 3(b). FIGS. 3(a) and 3(b) are configuration diagrams of the microphone device 2 according to the second embodiment. FIG. 3(a) shows a view from the direction in which the first member 30 and the second member 40 are planar (the Z-axis direction), and FIG. 3(b) shows a cross-sectional view of the AA section in FIG. 3(a) as viewed from the +Y-axis direction. FIGS. 3(a) and 3(b) are diagrams illustrating details of a holding portion 50c that suppresses force transmission to the first member 30 and the second member 40. The holding portion 50c is provided so that the distance from the inner side surface 50a of the housing 50 to the connection portion 50d is long. That is, the connection portion (first connection portion) 50d is provided in the region of the holding portion 50c that is farthest from the connection portion (second connection portion) 50f with the inner side surface 50a of the housing 50. For simplicity of explanation, the microphone element 10 and the wiring 20 are omitted in FIGS. 3(a) and 3(b).

[0028] Two holders 50c extend along the Y-axis direction relative to the housing 50. The two holders 50c are substantially parallel to each other, and each has a bridge shape extending such that both ends of the holders 50c are connected to the inner side surface 50a of the housing 50. As shown in FIG. 3(b), a connecting portion 50d is provided on the holder 50c to hold the first member 30 and the second member 40, which are disposed in the ±Z-axis directions relative to the holder 50c. The first member 30 and the second member 40 are fixed to the connecting portion 50d with fixing members such as screws, and the positions of the first member 30 and the second member 40 in the thickness direction (Z-axis direction) are determined relative to each other.

[0029] Next, we will explain the behavior when a force is applied to the microphone device 2. Figure 3(a) shows a state in which forces F1 and F2 are applied in the Y-axis direction when the user 400 grips the housing 50. The forces F1 and F2 are generated when the user 400 grips the housing 50, and the forces F1 and F2 are balanced. The forces F1 and F2 are distributed and propagated to the two holders 50c as forces f1 and f2, respectively. The forces f1 and f2 are balanced on the holders 50c, and the holders 50c are in a state in which stress is applied due to the balance of the forces f1 and f2.

[0030] In this embodiment, a protrusion 50e protruding in the X-axis direction is provided at the midpoint of the holding portion 50c, and a connection portion 50d is disposed on the protrusion 50e. The protrusion 50e of the holding portion 50c is located farther from the inner side surface 50a of the housing 50 than other portions of the holding portion 50c. Therefore, the distance over which stress propagates to the connection portion 50d is longer than that of other portions of the holding portion 50c. By increasing the distance over which stress propagates, it is possible to distribute the stress on the holding portion 50c and reduce the force applied to the connection portion 50d and the first member 30 and second member 40 fixed to the connection portion 50d.

[0031] On the other hand, if the protrusion 50e is located close to the inner side surface 50a of the housing 50, the distance over which the stress propagates becomes shorter, and the stress may not be sufficiently dispersed by the retaining portion 50c. If the stress cannot be sufficiently dispersed, the forces f1 and f2 are transmitted more strongly, which means that a stronger force is applied to the connecting portion 50d and the first member 30 and the second member 40 fixed to the connecting portion 50d, which is undesirable.

[0032] In this way, by increasing the distance from the inner side surface 50a of the housing 50 to the connection portion 50d and dispersing the stress, the force transmitted to the first member 30 and the second member 40 can be suppressed.

[0033] Next, we will explain a state in which forces F3 and F4 are applied in the X-axis direction, as shown in FIG. 3(a). The directions of forces F3 and F4 are perpendicular (X-axis direction) to the direction in which the holding portion 50c extends (Y-axis direction). The area near the inner side surface 50a of the housing 50, where forces F3 and F4 are generated, and the protrusion 50e are separated by a distance (distance in the Y-axis direction). Therefore, the stress generated by forces F3 and F4 is transmitted along the side surface of the housing 50, bypassing the holding portion 50c. In this way, the propagation distance of forces F3 and F4 is longer than the propagation distance of forces F1 and F2, making it possible to further suppress the propagation of stress.

[0034] According to this embodiment, by providing the connection portion 50d on the holding portion 50c at a position away from the inner side surface 50a of the housing 50, it is possible to suppress the force applied to each of the first member 30 and the second member 40. As a result, it is possible to reduce abnormal sounds (noise) generated when force is applied to the wiring 20. [Example]

[0035] Next, a microphone device 3 according to a third embodiment of the present invention will be described with reference to FIGS. 4(a) and 4(b). FIGS. 4(a) and 4(b) are configuration diagrams of the microphone device 3 according to the third embodiment, showing details of a holding portion 50c that suppresses the transmission of force to the first member 30 and the second member 40. The holding portion 50c extends in a substantially L-shape relative to a corner 50b of the inner side surface 50a of the housing 50, and a connection portion 50d is provided in an area near the corner 50b. FIG. 4(a) shows a view when the first member 30 and the second member 40 are viewed from a direction in which they are flat (the Z-axis direction), and FIG. 4(b) shows a cross-sectional view of the BB cross section in FIG. 4(a) viewed from the +Y-axis direction.

[0036] A holding portion 50c extends from an inner side surface 50a of the housing 50. The holding portion 50c has a generally L-shape so as to fit along a corner 50b of the housing 50. As shown in FIG. 4(b), a connecting portion 50d that holds the first member 30 and the second member 40 in the Z-axis direction is provided in an area near the corner 50b of the housing 50. The first member 30 and the second member 40 are fixed to the connecting portion 50d with fixing members such as screws, and the positions of the first member 30 and the second member 40 in the thickness direction (Z-axis direction) are determined relative to each other.

[0037] Next, the effect of providing a connection portion 50d in a region near the corner 50b of the housing 50 will be described. The holding portion 50c shown in FIG. 4(a) has a rib shape for reinforcement to suppress bending and deformation when the user 400 grips the side of the housing 50. Force F5 indicates the force exerted when the user 400 grips the housing 50 at a position away from the corner 50b of the housing 50. Force F6 indicates the force exerted when the user 400 grips the region near the corner 50b of the housing 50. If forces F5 and F6 are equal, applying a force from outside the housing 50 at the position of force F5 causes the side of the housing 50 to bend and deform, with the corner 50b serving as a fulcrum. As the side of the housing 50 deforms, force F5 must be absorbed by the connection portion 50d and the first and second members 30 and 40 connected to the connection portion 50d. As a result, a strong force is applied to the first and second members 30 and 40.

[0038] The amount of deformation of the side surface of the housing 50 is suppressed more in the region near the corner 50b where the force is applied, i.e., the position of force F6. By providing the connection portion 50d as a holding portion in a position where the amount of deformation when force is applied is small (preferably a position where the amount of deformation is minimum), i.e., in a region with high rigidity, it is possible to suppress deformation of the first member 30 and the second member 40. As a result, it is possible to suppress the force applied to the wiring 20. [Example]

[0039] Next, a microphone device 4 according to a fourth embodiment of the present invention will be described with reference to Fig. 5. Fig. 5 is a cross-sectional view of the microphone device 4 according to the fourth embodiment. As shown in Fig. 5, the microphone device 4 has a microphone element 10, wiring 20, a first member 30, a second member 40, and a housing 50. The microphone element 10, wiring 20, first member 30, and second member 40 are housed inside the housing 50.

[0040] The microphone element 10 is covered with a first damping member 70 and is held by the housing 50 via the first damping member 70. The first damping member 70 is an elastic member such as natural rubber, silicone rubber, or sponge. The housing 50 has a substantially rectangular parallelepiped outer shape. A holding portion 50c having a rib-like internal shape extending toward the center of the housing 50 (the -X-axis direction in FIG. 5) is provided substantially vertically on the inner side surface 50a of the housing 50. The holding portion 50c is provided with a connection portion 50d protruding in the Z-axis direction.

[0041] A second damping member 80 is provided at the tip of the connecting portion 50d. The second damping member 80 is an elastic member such as natural rubber, silicone rubber, or sponge. The first member 30 and the second member 40 are fixed to the connecting portion 50d via the second damping member 80 by fixing members such as screws, retaining pins, or light press-fitting using holes and shafts (not shown), and are positioned relative to the housing 50.

[0042] The first member 30 and the second member 40 are each an electronic substrate having a substantially plate shape. At least one of the first member 30 and the second member 40 is electrically connected to the wiring 20. The first member 30 and the second member 40 are arranged so as to be substantially parallel to each other at positions spaced apart in the Z-axis direction due to the difference in height between the connecting portions 50d of the rib-shaped holding portions 50c. In other words, the holding portions 50c hold the first member 30 and the second member 40 so as to be perpendicular to the thickness direction (Z-axis direction) of the housing 50, thereby determining the positions of the first member 30 and the second member 40 in the Z-axis direction. This difference in height forms a space 60 between the first member 30 and the second member 40. The microphone element 10 and the wiring 20 are electrically connected.

[0043] One end of the wiring 20 penetrates a portion of the first damping member 70 covering the microphone element 10 and is connected to the microphone element 10. The other end of the wiring 20 (the end opposite to the end connected to the microphone element 10) is electrically connected to either the first member 30 or the second member 40. A portion of the wiring 20 is stored in a bent state inside a space 60 formed between the first member 30 and the second member 40. The wiring 20 comes into contact with both the first member 30 and the second member 40 due to a repulsive force generated when the wiring 20 is bent.

[0044] When the area of ​​the wiring 20 adjacent (neighboring) to the inner side surface 50a of the housing 50 is defined as the wiring section 20a, a third damping member 90 is provided between the wiring section 20a and the inner side surface 50a of the housing 50. The third damping member 90 is an elastic member such as natural rubber, silicone rubber, or sponge. One surface (first surface) of the third damping member 90 is fixed to the inner side surface 50a of the housing 50 with an adhesive member such as tape or adhesive, and the other surface (second surface opposite the first surface) is in contact with the wiring section 20a.

[0045] In this embodiment, components that are in mechanical contact with the housing 50 or that may come into contact due to variations in assembly are held or biased via a damping member. By using a damping member, it is possible to suppress vibrations or impacts transmitted from the housing 50 to the first member 30 and the second member 40, or the wiring 20. This makes it possible to suppress abnormal sounds (noises) caused by vibrations or impacts that occur when the user 400 wears the microphone device 4. [Example]

[0046] Next, a microphone device according to a fifth embodiment of the present invention will be described with reference to Figures 6(a) to (d). This embodiment is a modified version of the microphone devices 1 to 4 according to the first to fourth embodiments. Figures 6(a) to (d) show selected internal components of the microphone devices 1 to 4 described in the first to fourth embodiments, and show a state in which the microphone element 10, the wiring 20, the first member 30, and the second member 40 are held by a housing 50 (not shown). Figures 6(a) and (b) are diagrams showing the collapse of the wiring 20, and Figures 6(c) and (d) are explanatory diagrams showing how to prevent the collapse.

[0047] In FIG. 6(a), the wiring 20 is stored in a space 60 formed between the first member 30 and the second member 40 with a portion of the wiring 20 bent. The wiring 20 is biased toward both the first member 30 and the second member 40 by an elastic force generated when the wiring 20 is bent. This biasing force causes the wiring 20 to contact both the first member 30 and the second member 40. In this state, if there is variation in assembly or if the microphone devices 1 to 4 are subjected to vibration or impact, the orientation of the wiring 20 may become unstable and the wiring 20 may fall over as shown in FIG. 6(b). Note that FIG. 6(b) shows FIG. 6(a) viewed from the -X-axis direction, showing the folded portion of the wiring 20 viewed from the end.

[0048] In FIG. 6( b), the wiring 20 is tilted in the direction of the arrow cw and is biased against the first member 30 and the second member 40 by the elastic force of the wiring 20. The biasing force at this time is larger when the wiring 20 is bent than the biasing force before the wiring 20 tilted. Therefore, the biasing force decreases in proportion to the decrease in the elastic force of the wiring 20. Furthermore, vibration or impact may cause the wiring 20 to tilt further. If the wiring 20 tilts, it will no longer be able to bias the wiring 20 against the first member 30 and the second member 40 with the desired elastic force. As a result, the wiring 20 becomes unstable and hangs in the space 60. If vibration or impact is applied to the wiring 20 while it is hanging in the air, the wiring 20 may repeatedly collide with other members, potentially generating noise.

[0049] FIG. 6(c) shows a state in which the wiring 20 described with reference to FIG. 6(a) is maintained in its position by a fixing member 130 such as an adhesive or tape to prevent it from falling over. FIG. 6(d) shows FIG. 6(c) viewed from the -X-axis direction. By using the fixing member 130 to hold at least one of the contact positions between the wiring 20 and the first member 30 and the contact position between the wiring 20 and the second member 40, it is possible to prevent the wiring 20 from falling over due to vibration or impact. This makes it possible to suppress abnormal noise that occurs when the wiring 20 collides with another member. [Example]

[0050] Next, a microphone device 5 according to a sixth embodiment of the present invention will be described with reference to Fig. 7. Fig. 7 is a cross-sectional view of the microphone device 5 according to the sixth embodiment. The microphone device 5 according to the sixth embodiment differs from the microphone device 1 according to the first embodiment in that it has a fourth damping member 100 and an intermediate member 140 instead of the holding portion 50c. Note that a description common to the first embodiment will be omitted.

[0051] The intermediate member 140 is a holding member that holds the first member 30 and the second member without coming into contact with the housing 50. This determines the relative positions of the first member 30 and the second member 40. The fourth damping member 100 is configured to hold the microphone element 10, the first member 30, the second member 40, and the intermediate member 140 in the housing 50. In other words, the microphone element 10, the first member 30, the second member 40, and the intermediate member 140 are disposed inside the housing 50 via the fourth damping member 100.

[0052] In this embodiment, the microphone element 10, first member 30, second member 40, and intermediate member 140 are disposed inside the housing 50 via the fourth damping member 100, and each member is spaced apart and does not directly contact the inner side surface 50a of the housing 50. By disposing the wiring 20 and each member in contact with the wiring 20 inside the housing 50 via a single damping member (the fourth damping member 100), the damping member that holds each member while suppressing vibrations transmitted from the housing 50 to the wiring 20 can be integrated into a single component. By consolidating the internal components into a single damping member, the number of components can be reduced and assembly can be improved. Although the fourth damping member 100 is shown as U-shaped in this embodiment, it is sufficient that the fourth damping member 100 is configured to cover all of the internal components and prevent them from contacting the inner side surface 50a of the housing 50. [Example]

[0053] Next, a microphone device 6 according to a seventh embodiment of the present invention will be described with reference to Fig. 8. Fig. 8 is a cross-sectional view of the microphone device 6 according to the seventh embodiment. The microphone device 6 according to the present embodiment differs from the microphone device 1 according to the first embodiment in that it includes a fifth damping member 110. Note that a description common to the first embodiment will be omitted.

[0054] The fifth damping member 110 has a box shape 110a having a space for accommodating the wiring 20. At least a portion of the box shape 110a extends in the +X-axis direction so as to be disposed inside the space 60. A through-hole 110b is formed in the box shape 110a for electrically connecting the wiring 20 to either the first member 30 or the second member 40. The wiring 20 is accommodated inside the box shape 110a in a bent state in the space 60 formed between the first member 30 and the second member 40. At this time, the wiring 20 is biased toward each of the first member 30 and the second member 40 by an elastic force generated when the wiring 20 is bent. Due to this biasing force, the wiring 20 contacts each of the first member 30 and the second member 40 via the box shape 110a of the fifth damping member 110.

[0055] In this embodiment, a box-shaped portion 110a that houses the wiring 20 is provided in a portion of the fifth damping member 110, and the wiring 20 is biased against each of the first member 30 and the second member 40 via the fifth damping member 110. The fifth damping member 110 that covers the microphone element 10 is expanded to form a space of the box-shaped portion 110a, and the wiring 20 comes into contact with each of the first member 30 and the second member 40 via the fifth damping member 110. This makes it possible to hold the wiring 20 within the space 60 while suppressing vibrations transmitted from the first member 30 or the second member 40 to the wiring 20. In addition, an opening 110c is formed in the box-shaped portion 110a through which the wiring 20 is bent. The length of the wiring 20 may be adjusted through the opening 110c when bending the wiring, or the wiring 20 may be pulled out through the through-hole 110b. [Example]

[0056] Next, a microphone device 7 according to an eighth embodiment of the present invention will be described with reference to Figures 9(a) to 9(c). Figure 9(a) is a cross-sectional view of the microphone device 7 of this embodiment, and Figures 9(b) and 9(c) are explanatory diagrams of a sixth damping member 120. The microphone device 7 of this embodiment differs from the microphone device 1 of the first embodiment in that it has the sixth damping member 120. Note that descriptions common to the first embodiment will be omitted.

[0057] Fig. 9(b) is a detailed explanatory diagram of the sixth damping member 120 covering the microphone element 10, showing the state before the wiring 20 is bent. Fig. 9(c) is a diagram of Fig. 9(b) viewed in the -X axis direction, showing the state in which the wiring 20 is housed in the sixth damping member 120. Note that the wiring 20 is shown in more detail as two wires wound in a spiral shape.

[0058] 9(b) and 9(c), the sixth damping member 120 has a sheet-shaped protruding portion 120a. The protruding portion 120a is provided with a plurality of holding portions 120b. The holding portions 120b are formed with through holes 120c for holding the wiring 20. With the wiring 20 passing through the through holes 120c, the protruding portions 120a and the wiring 20 extend in approximately the same direction.

[0059] The wiring 20 and a portion of the protrusion 120a are both stored in a bent state inside the space 60 formed between the first member 30 and the second member 40. At this time, the wiring 20 is biased toward each of the first member 30 and the second member 40 by an elastic force generated when the wiring 20 is bent. This biasing force causes the wiring 20 to contact each of the first member 30 and the second member 40 via the protrusion 120a of the sixth damping member 120. This suppresses vibration transmitted from the first member 30 or the second member 40 to the wiring 20, while simplifying the shape of the damping member and incorporating it simultaneously with the wiring 20, thereby improving ease of assembly.

[0060] As described above in each embodiment, the wiring 20 is housed in the space 60 formed by the first member 30 and the second member 40 provided inside the housing 50. However, each embodiment is not limited to this, and the housing 50 may be integrally formed with the first member 30 and the second member 40. In this case, the housing 50 has a dual structure consisting of an external housing (first housing) and an internal housing (corresponding to the second housing, the first member 30, and the second member 40) provided inside the external housing. The internal housing has a space (corresponding to the space 60) for housing the wiring 20, and the wiring 20 is housed in the space inside the internal housing while being electrically connected to the microphone element 10 and the internal housing. In this way, the wiring 20 does not come into contact with the inner side surface 50a of the external housing, which is subject to force or vibration, so the housing 50 may have a dual structure.

[0061] According to each embodiment, it is possible to provide a microphone device that can suppress the generation of noise that is transmitted to the wiring due to the force or impact when the user grips the housing.
