A distance in the Z direction from the contact surface 110 of the mounting component 100 to the first and second flanges 131 and 132 is defined as a distance D1 (see FIG. 2C). The distance D1 is slightly smaller than the distance D2. Therefore, when the first and second flanges 131 and 132 are inserted into the first and second engagement recesses 241 and 242, the first and second flanges 131 and 132 become the first and second engagement recesses 241. , And the contact surface 110 of the attachment component 100 contacts the second end surface 222 of the holder 200. As a result, the holder 200 is sandwiched between the contact surface 110 and the first and second flanges 131 and 132, and the holder 200 is compressed (elastically deformed) between the contact surface 110 and the first and second flanges 131 and 132. ) Thereby, the holder 200 presses the contact surface 110 to the other side in the Z direction and the first and second flanges 131 and 132 to the one side in the Z direction.

  As shown in FIG. 1, the holding unit 400 is a cylinder made of an insulating resin. The inner diameter of the holding part 400 is slightly larger than the outer diameter of the holder main body 210 of the holder 200.

A switch 500 is provided in the housing 300. The switch 500 and the mounting part 100 are connected by a lead wire 600. When the switch 500 is turned on, the attachment component 100 is turned on. The microphone head has a spherical shell shape and can be attached to the housing 300. The microphone head covers the holding unit 400, the holder 200, and the attachment component 100 attached to the housing 300 while being attached to the housing 300.

  Hereinafter, the above-described microphone assembly procedure will be described in detail. First, the attachment component 100 and the lead wire 600 are prepared. Thereafter, the lead wire 600 is connected to the attachment component 100. Thereafter, the holder 200 is prepared. Thereafter, the first and second flanges 131 and 132 of the attachment component 100 are inserted into the first and second guide recesses 231 and 232 of the holder 200, and the insertion portion 120 of the attachment component 100 is inserted into the holder 200. Then, the contact surface 110 of the attachment component 100 contacts the second end surface 222 of the holder 200. At this time, the insertion part 120 slides on the ridge 213 of the holder 200 in the Z direction.

  In this state, the attachment component 100 is rotated relative to the holder 200 in one side in the circumferential direction α. Thereby, the insertion part 120 rotates to one side of the circumferential direction α in the holder 200 while sliding on the ridge 213. Accordingly, the first and second flanges 131 and 132 move in the circumferential direction α, get over the first and second peak portions 251 and 252, and are inserted into the first and second engagement recesses 241 and 242. . Then, the first and second flanges 131 and 132 come into contact with the bottom surfaces 241a and 242a of the first and second engagement recesses 241 and 242, respectively. Accordingly, the holder 200 is sandwiched between the contact surface 110 and the first and second flanges 131 and 132, and the holder 200 is elastically deformed. In this way, the attachment component 100 is elastically attached to the holder 200.

  Thereafter, the holding unit 400 is prepared. Thereafter, the lead wire 600 is inserted into the holding unit 400. Thereafter, the holder 200 is fitted into the holding part 400. At this time, the convex part 270 of the holder 200 is fitted into the fitting hole 410 of the holding part 400.

  Thereafter, the housing 300 provided with the switch 500 is prepared. Thereafter, the lead wire 600 is connected to the switch 500. Thereafter, the lower end portion of the holding portion 400 is fitted into the housing 300. In this manner, the attachment component 100, the holder 200, and the holding portion 400 are attached to the housing 300, and the attachment component 100 is electrically connected to the switch 500. Thereafter, the microphone head is prepared. Thereafter, the microphone head is attached to the housing 300 so as to cover the attachment component 100 with the microphone head.

  In the case of the above-described microphone, the attachment part 100 can be attached to the holder 200 simply by inserting the insertion portion 120 of the attachment part 100 into the holder 200 and rotating it to one side in the circumferential direction α. It can be easily attached to the holder 200. Further, the holder 200 is sandwiched between the contact surface 110 of the mounting component 100 and the first and second flanges 131 and 132. Further, since the distance D1 is slightly smaller than the distance D2, the holder 200 is elastically deformed in the above-described clamping state, and the contact surface 110 of the mounting part 100 and the first and second flanges 131 and 132 are elastically deformed. Is pressed. For this reason, it is possible to prevent the attachment component 100 from jumping out of the holder 200. Further, since the first and second flanges 131 and 132 of the mounting part 100 are prevented from moving to the other side in the circumferential direction α by the first and second peak portions 251 and 252 of the holder 200, the mounting part 100 Can be prevented from inadvertently rotating to the other side in the circumferential direction α, and the mounting component 100 can be prevented from jumping out of the holder 200.

  Further, as described above, since the mounting component 100 is elastically held by the holder 200, even if an impact is applied to the microphone from the outside, the impact can be absorbed by the holder 200, and the touch noise of the microphone can be reduced. Reduction can be achieved. Further, the vibration of the attachment component 100 itself that is a microphone unit can also be absorbed by the holder 200.

  Further, since the outer shapes of the first and second flanges 131 and 132 are different, the first and second flanges 131 and 132 rotate in the rotational direction (one side of the circumferential direction α) for attaching the attachment component 100 to the holder 200. ). Therefore, it is possible to prevent the insertion part 120 of the attachment component 100 from being erroneously rotated in the holder 200 to the other side in the circumferential direction α.

  Next, a microphone according to Embodiment 2 of the present invention will be described with reference to FIGS. The microphone shown in FIG. 5 is different from the microphone of the first embodiment except for the shape of the holder 200 ′, the distance D2 ′, and the dimension of the insertion portion 120 of the attachment component 100 in the Z direction. The configuration is substantially the same. Therefore, the above-described differences will be described in detail, and descriptions overlapping with those in the first embodiment will be omitted. Note that the reference numeral of the holder is marked with 'to distinguish it from the holder 200 of the first embodiment. Use the same reference numbers for the mounting parts.

  The holder 200 ′ has substantially the same configuration as the holder 200 except that the holder 200 ′ is different from the holder 200 of the first embodiment in the following points. The first point is that the first and second engagement recesses 241 and 242 are not provided on the first end surface 221 'of the holder 200' as shown in FIGS. 6A and 6B. The second point is that the first and second peak portions 251 ′ and 252 ′ of the holder 200 ′ are provided on one side in the circumferential direction α of the first and second guide recesses 231 ′ and 232 ′ on the first end surface 221 ′. It is being done. The first and second peak portions 251 ′ and 252 ′ have inclined surfaces 251 a ′ and 252 a ′ on the first and second guide recesses 231 ′ and 232 ′ side. The inclined surfaces 251a 'and 252a' are inclined to one side in the Z direction and one side in the circumferential direction α. In addition, 211 'in FIGS. 5-6B is an attachment hole. Reference numeral 212 'denotes an inner peripheral surface. Reference numeral 213 'denotes a striated pulse.

  The dimension in the Z direction of the insertion part 120 is longer than the dimension in the Z direction of the insertion part 120 of the first embodiment in order to realize a relationship between distances D1 and D2 'described later. The first and second flanges 131 and 132 get over the inclined surfaces 251a ′ and 252a ′ of the first and second peak portions 251 ′ and 252 ′ as the insertion portion 120 rotates to one side in the circumferential direction α. The first and second flanges 131 and 132 are in contact with the first end surface 221 ′.

  The distance D2 'is a distance in the Z direction from the first end surface 221' to the second end surface 222 'of the holder 200'. The distance D1 is set slightly smaller than the distance D2 '. Therefore, when the first and second flanges 131 and 132 of the attachment component 100 abut on the first end surface 221 ′, the abutment surface 110 of the attachment component 100 abuts on the second end surface 222 ′ of the holder 200 ′, The holder 200 ′ is sandwiched between the contact surface 110 and the first and second flanges 131 and 132. Since the holder 200 ′ is compressed (elastically deformed) between the contact surface 110 and the first and second flanges 131 and 132, the holder 200 ′ has the first contact surface 110 on the other side in the Z direction. The second flanges 131 and 132 are pressed to one side in the Z direction.

  Hereinafter, the above-described microphone assembly procedure will be described in detail. First, the mounting component 100 and the holder 200 ′ to which the lead wire 600 is connected are prepared. Thereafter, the first and second flanges 131 and 132 of the mounting part 100 are inserted into the first and second guide recesses 231 ′ and 232 ′ of the holder 200 ′, and the insertion part 120 of the mounting part 100 is inserted into the holder 200 ′. To do. Then, the contact surface 110 of the mounting part 100 contacts the second end surface 222 ′ of the holder 200 ′, and the first and second flanges 131 and 132 are connected to the first and second guide recesses 231 ′ and 232 ′ of the holder 200 ′. Is inserted. At this time, the insertion portion 120 slides on the ridge 213 'of the holder 200' in the Z direction.

  In this state, the attachment component 100 is rotated to one side in the circumferential direction α relative to the holder 200 ′. As a result, the insertion portion 120 rotates on one side in the circumferential direction α within the holder 200 ′ while sliding on the ridge 213 ′. Accordingly, the first and second flanges 131 and 132 move in the circumferential direction α, get over the first and second peak portions 251 ′ and 252 ′, and come into contact with the first end surface 221 ′. As a result, the holder 200 ′ is sandwiched between the contact surface 110 and the first and second flanges 131 and 132, and the holder 200 ′ is elastically deformed. In this way, the attachment component 100 is elastically attached to the holder 200 '. Subsequent microphone assembly procedures are as described in the first embodiment.

  In the case of using the above-described microphone, the same effect as in the first embodiment can be obtained.

  The microphone and the mounting structure described above are not limited to the above-described embodiments, and can be arbitrarily changed in design within the scope of the claims. Details will be described below.

  In the first and second embodiments, the attachment component 100 has the contact surface 110, the insertion portion 120, and the first and second flanges 131 and 132. However, the mounting part has an abutment surface having an outer shape larger than the inner shape of the holder, and an insertion portion projecting on the abutment surface and inserted into the holder and having an outer shape rotatable in the circumferential direction. As long as the first and second flanges are provided on the outer peripheral surface of the insertion portion at intervals in the circumferential direction, the design can be arbitrarily changed. Therefore, the first and second flanges can be provided on the outer peripheral surface of the insertion portion with an interval other than 180 °. Moreover, it is possible to change the design so that three or more flanges are provided on the outer peripheral surface of the insertion portion at intervals in the circumferential direction.

  In the first and second embodiments, the outer shapes of the first and second flanges 131 and 132 are different. However, the first and second flanges can have the same outer shape.

  In the first and second embodiments, the first and second guide recesses 231, 232, 231 ′, 232 ′ are spaced by 180 ° in the circumferential direction α on the inner peripheral surfaces 212, 212 ′ of the holders 200, 200 ′. It has been provided. However, the first and second guide recesses can be provided on the inner peripheral surface of the holder with an interval other than 180 °. Further, as described above, when the mounting part has three or more flanges, three or more guide recesses into which the flanges can be inserted may be provided on the inner peripheral surface of the holder with a gap in the circumferential direction.

  In the first and second embodiments, the ridges 213 and 213 'are provided on the inner peripheral surfaces 212 and 212' of the holders 200 and 200 '. However, the pulsation can be omitted. In this case, it is possible to change the design so that the insertion part of the attachment part contacts or does not contact the inner peripheral surface of the holder.

  In the first embodiment, the first and second peak portions 251 and 252 are provided on the bottom surfaces 241 a and 242 a of the first and second engaging recesses 241 and 242 of the holder 200. In the second embodiment, the first and second peak portions 251 'and 252' are provided on the first end surface 221 'of the holder 200'. However, the first and second peak portions can be omitted. When the first and second peak portions are omitted, when the insertion portion rotates in the circumferential direction in the holder, the first flange comes into contact with the bottom surface or the first end surface of the first engagement recess, and the second flange Comes into contact with the bottom surface or the first end surface of the second engaging recess, and the holder is held between the contact surface and the first and second flanges. In addition, the first and second peak portions can be changed to a configuration having no slope.

  In the first and second embodiments, the attachment component 100 and the switch 500 are connected by the lead wire 600. However, it is not limited to this. For example, as shown in FIG. 7A, the first and second electrodes 141 and 142 are provided on the first and second flanges 131 and 132 of the mounting part 100, and the first and second engaging recesses 241 of the holder 200 are provided. The third and fourth electrodes 281 and 282 may be provided on the bottom surfaces 241a and 242a of the 242. The third and fourth electrodes 281 and 282 are electrically connected to the switch 500. In this case, the insertion portion 120 of the attachment component 100 rotates in the holder 200 to one side in the circumferential direction α, and the first and second flanges 131 and 132 are the bottom surfaces 241a of the first and second engagement recesses 241 and 242, The first and second electrodes 141 and 142 and the third and fourth electrodes 281 and 282 come into contact with each other when contacting the 242a. Also, as shown in FIG. 7B, the first and second electrodes 141 and 142 are provided on the first and second flanges 131 and 132 of the mounting part 100, and the third is formed on the first end surface 221 ′ of the holder 200 ′. The fourth electrodes 281 ′ and 282 ′ may be provided. The third and fourth electrodes 281 ′ and 282 ′ are electrically connected to the switch 500. In this case, when the insertion part 120 of the mounting part 100 rotates to one side in the circumferential direction α in the holder 200 and the first and second flanges 131 and 132 come into contact with the first end surface 221 ′, the first and second The electrodes 141 and 142 are in contact with the third and fourth electrodes 281 ′ and 282 ′. When the design is changed in this way, the electrical connection between the mounting part 100 and the switch 500 is facilitated. The thickness dimensions of the first, second, third, and fourth electrodes in FIGS. 7A and 7B are exaggerated for convenience of explanation. Note that the above-described switch 500 can be replaced with another electronic component such as a board or a microcomputer.

In the first and second embodiments, the holders 200 and 200 ′ are attached to the holding unit 400, and the holding unit 400 is attached to the housing 300. However, it is possible to fix the holder directly to the housing. It is also possible to provide the holder integrally with the housing.

  The mounting component described above is a microphone unit. However, the design of the mounting part can be arbitrarily changed to a unit other than the microphone unit (speaker unit, sensor unit, switch unit, etc.) or another mounting part that is not a unit. That is, the mounting structure of the mounting component and the holder described above can be applied to the mounting structure of a component other than the microphone unit and the holder.

  It should be noted that the materials, shape, dimensions, number, arrangement, etc. constituting the mounting structure and each part of the microphone in the above-described embodiment are examples, and the design can be arbitrarily changed as long as the same function can be realized. Is possible.
