  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
1 and 2 are exploded perspective views of a part of a digital camera as an electronic apparatus according to the first embodiment of the present invention. The digital camera according to the present embodiment includes a speaker 102a and a pair of microphones 102b (a left audio input microphone 102bL and a right audio input microphone 102bR). As shown in FIGS. 1 and 2, the front cover 101 is a part of the exterior member of the digital camera. When a camera as a product is used, the upper plate portion 11 of the front cover 101 as an exterior member is normally used as the upper side. Henceforth, the directions of the front side and the back side of the upper plate portion 11 are referred to as the upper and lower directions, respectively. To do. Further, the longitudinal direction of the upper plate portion 11 is referred to as the left-right direction. Therefore, the surface which becomes the outer side surface of the exterior member in the upper plate portion 11 is the front surface 101h (see FIG. 1), and the surface which becomes the inner side surface of the exterior member is the back surface 101g (see FIG. 2).

  1 and 2 mainly show components related to the assembly of the speaker 102a and the pair of microphones 102b. FIG. 1 is a perspective view obliquely from above and FIG. 2 is a perspective view from obliquely below. Inside the front cover 101, a flexible printed circuit board (hereinafter referred to as FPC) 102, a sheet metal 103 for fixing the FPC 102, and a holding member 104 are disposed. On the back side of the upper plate part 11, the holding member 104, the FPC 102, and the sheet metal 103 are disposed in this order from the top.

  The holding member 104 is integrally formed of an elastic member, and integrally holds the speaker 102a and the microphones 102bL and 102bR. In the present embodiment, a rubber material is employed as an example of the elastic member that constitutes the holding member 104, but the type is not limited as long as the elastic member has sufficient elasticity.

  As shown in FIG. 1, the upper plate portion 11 of the front cover 101 is formed with a speaker hole 101a for transmitting sound emitted from the speaker 102a to the outside. Microphone holes 101bL and 101bR for the left audio input microphone 102bL and the right audio input microphone 102bR to pick up sound from outside are formed on both sides of the speaker hole 101a in the left-right direction. The microphone holes 101bL and 101bR are disposed adjacent to the speaker hole 101a with the speaker hole 101a interposed therebetween, and form a pair of left and right. The speaker hole 101a and the microphone holes 101bL and 101bR all open on the surface 101h, which is the same surface.

  A recess 101c for assembling a release button (not shown) is also formed in the upper plate portion 11 of the front cover 101. A shooting preparation operation (photometry operation, focus adjustment operation, etc.) is started by half-pressing the release button, and a shooting operation (exposure to an image sensor such as a CCD (not shown)) is started by full-pressing operation. The upper plate 11 also has a hole 101d for attaching a power button (not shown) for turning on / off the power, and a hole 101e for attaching a zoom lever (not shown) for zooming a lens (not shown). It is formed.

  As shown in FIG. 2, bosses having fastening holes 101 i are projected at three positions on the back surface 101 g of the upper plate portion 11. Moreover, the protrusion part 101f for positioning the sheet metal 103 is formed in two places.

  As shown in FIG. 1, the FPC 102 includes a speaker 102a, microphones 102bL and 102bR, a release switch 102c, a zoom switch 102e, and a power switch 102d. The FPC 102 is connected to a main wiring board 106 (see FIG. 7) described later. The release switch 102c and the zoom switch 102e are two-stage switches. The microphones 102bL and 102bR are arranged on both the left and right sides with the speaker 102a interposed therebetween. The microphones 102bL and 102bR have a pair of stereo-type microphones, which are for the L channel and the R channel, respectively. The FPC 102 is also formed with positioning holes 102 f for positioning the sheet metal 103.

  The positions of the speaker 102a and the microphones 102bL and 102bR correspond to the positions of the speaker hole 101a and the microphone holes 101bL and 101bR in the upper plate portion 11 of the front cover 101, respectively. The positions of the power switch 102d, zoom switch 102e, and release switch 102c correspond to the positions of the hole 101d, hole 101e, and recess 101c in the upper plate part 11, respectively.

  As shown in FIG. 1, the sheet metal 103 is formed with a plurality (three) of screw through holes 103a, a plurality (two) of positioning through holes 103b, and a pin caulking portion 103c, and two aperture protrusions. A shape portion 103d is formed to project from the upper side. The positions of the screw through holes 103a and the positioning through holes 103b correspond to the positions of the fastening holes 101i and the protrusions 101f in the upper plate portion 11 of the front cover 101. Further, the positions of the pin crimping portion 103c and the iris convex portions 103d and 103d correspond to the positions of the positioning hole 102f and the microphones 102bL and 102bR in the FPC 102.

  The FPC 102 and the sheet metal 103 are assembled to the front cover 101 as follows. First, various components are mounted on the FPC 102 in advance, and the FPC 102 and the holding member 104 are assembled (described later in FIGS. 3 to 5).

  Then, the FPC 102 is assembled to the sheet metal 103. At that time, the bent portion 102h2 is bent with respect to the plate portion 102h1 on the side where the speaker 102a of the FPC 102 is mounted, and the plate portion 103h1 and the bent portion 102h2 are assembled so that the sheet metal 103 is sandwiched from above and below. 1 and 2, the bent portion 102h2 is shown in a bent state. Further, when the FPC 102 is assembled to the sheet metal 103, each pin caulking portion 103c is inserted into the corresponding positioning hole 102f. Thereby, the sheet metal 103 and the FPC 102 are positioned. Further, the FPC 102 and the sheet metal 103 are fixed with a double-sided tape (not shown).

  Then, a combination of the FPC 102 and the sheet metal 103 is disposed on the upper plate portion 11 of the front cover 101 from the back side. At that time, the protruding portion 101 f of the upper plate portion 11 is inserted into the through hole of the FPC 102 corresponding to the positioning through hole 103 b and the positioning through hole 103 b of the sheet metal 103. The front cover 101 and the sheet metal 103 are positioned by the engagement between the protrusion 101f and the positioning through hole 103b.

  Thereafter, three screws 105 are inserted from below the sheet metal 103 into the screw through holes 103a of the sheet metal 103 and the through holes of the FPC 102 corresponding to the screw through holes 103a, and the fastening holes in the upper plate portion 11 of the front cover 101 are inserted. Thread into 101i. Thereby, the FPC 102 and the sheet metal 103 are fixed to the front cover 101.

  Next, a method for assembling the FPC 102 and the holding member 104 will be described. 3 and 4 are exploded perspective views of the FPC 102 and the holding member 104. FIG. FIG. 5 is a perspective view of the assembled FPC 102 and holding member 104.

  The FPC 102 is a single-sided mounting type printed circuit board, and a bent portion 102h2 is folded back with respect to a plate portion 102h1 on the side where the speaker 102a is mounted. The sound output surface of the speaker 102a and the sound input surfaces of the microphones 102bL and 102bR are in the same direction and face upward.

  A cylindrical elastic member 102aa, which is a “separate member” independent of the holding member 104, is fixed to the upper portion of the speaker 102a by pasting or the like (see FIG. 3). The mode of fixing is not limited. The elastic member 102aa is made of an elastic material, and preferably has a high impact absorption. As an example, PORON (registered trademark) is adopted. The elastic member 102aa may be the same material as the holding member 104, but preferably, a material having a hardness different from that of the holding member 104 is used.

  On the upper portion of the holding member 104 corresponding to the microphones 102bL and 102bR, a protruding portion 104c having a substantially rectangular shape in a plan view (frame shape) is provided so as to surround the opening of the sound input surface of the microphones 102bL and 102bR. They are provided twice (see FIG. 3). The protrusion 104c is formed for each of the L channel and the R channel.

  An opening 104a is formed in the holding member 104 so that the speaker 102a can be assembled from below the holding member 104 (see FIGS. 3 and 4). The speaker 102a is assembled by being pushed into the opening 104a from below. The holding member 104 has an opening 104b so that the microphones 102bL and 102bR can be assembled from below the holding member 104 (see FIG. 4). The microphones 102bL and 102bR are assembled so as to be pushed into the opening 104b from below.

  6 is a partial cross-sectional view taken along the line AA of FIG. 1 showing a state in which the FPC 102, the sheet metal 103, and the holding member 104 are assembled to the front cover 101. As shown in FIG.

  First, when the speaker 102a and the microphones 102bL and 102bR are assembled to the holding member 104, the result is as shown in FIG. As shown in FIG. 6, the elastic member 102aa protrudes upward from the opening 104a. The upper end of the protrusion 104c is the highest position of the holding member 104, and the upper ends of the protrusion 104c and the elastic member 102aa are substantially the same.

  As shown in FIG. 6, the speaker 102a is held in the opening 104a. The opening 104b is formed with a plurality of steps in the vertical direction, and the microphones 102bL and 102bR are held in a portion of the opening 104b above the lowermost lower opening 104b1. Therefore, the speaker 102a and the pair of microphones 102b are integrally held by the holding member 104 so as to be wrapped.

  When the FPC 102, the sheet metal 103, and the holding member 104 are assembled to the front cover 101, the holding member 104 is assembled so as to be pressed against the upper plate portion 11 of the front cover 101. Therefore, as shown in FIG. 6, the protrusion 104 c having the highest height among the holding members 104 is deformed by the elastic force of the rubber material and closely contacts the back surface 101 g of the upper plate portion 11. Thereby, the space S1L connected to the microphone hole 101bL and the upper surface 102b1L of the microphone 102bL is provided and shielded from the other space S0 inside the front cover 101. Furthermore, the space S1R connected to the microphone hole 101bR and the upper surface 102b1R of the microphone 102bR is also provided and shielded from the other space S0. The spaces S1L and S1R are sealed except for the microphone holes 101bL and 101b and the microphone 102b. Therefore, the sound insulation of the microphone 102b is ensured. In particular, since the protrusion 104c is double, the adhesiveness with the front cover 101 is high, and the sound input characteristics of the microphone 102b can be improved.

  In the present embodiment, the protrusion 104c has a double structure, but the shape is not limited to this shape as long as the shape can ensure adhesion. For example, instead of being double, a single surrounding shape may be used, and the width of the ridge may be widened to the same extent as the above double. Moreover, it is good also as not only a double but a triple or more.

  On the other hand, when the FPC 102, the sheet metal 103, and the holding member 104 are assembled to the front cover 101, the elastic member 102aa protruding from the opening 104a of the holding member 104 is also pressed by the upper plate portion 11 of the front cover 101. Therefore, as shown in FIG. 6, the elastic member 102aa is deformed by its elasticity and is in close contact with the back surface 101g of the upper plate portion 11 on the entire circumference. As a result, the space S2 connected to the speaker hole 101a and the upper surface 102a1 of the speaker 102a is imaged and shielded from the other space S0 inside the front cover 101, and is also shielded from the spaces S1L and S1R. The space S2 is hermetically sealed except for the speaker hole 101a and the speaker 102a. Therefore, the sound insulation of the speaker 102a is ensured, and it becomes difficult to pick up the noise inside the exterior and the sound of the microphone 102b.

  By the way, by assembling the holding member 104 to the FPC 102 to which the sheet metal 103 has been assembled, as described above, the microphones 102bL and 102bR are held in the opening 104b. Accordingly, each diaphragm convex portion 103d of the sheet metal 103 comes into contact with the lower surface 102b2L of the microphone 102bL and the lower surface 102b2R of the microphone 102bR, and closes the lower opening 104b1 of the corresponding opening 104b (FIG. 6). reference). Thereby, it becomes more difficult for the speaker 102a to pick up noise inside the exterior.

  FIG. 7 is a diagram showing the connection between the FPC 102 and the main wiring board 106. 8A is a diagram showing the wiring of the FPC 102, and FIG. 8B is an enlarged view showing the wiring of the mounting portions of the microphones 102bL and 102bR.

  As shown in FIG. 7, an audio circuit block 106b including an audio IC 106a is mounted on the main wiring board 106. The main wiring board 106 and the FPC 102 are connected by an inter-board connector 102g. The sound is captured as an electric signal by the microphones 102bL and 102bR. The audio circuit block 106b has a microphone amplifier that amplifies an electric signal output from the microphones 102bL and 102bR.

  In the audio circuit block 106b, the analog electric signal output from the microphone amplifier is converted into a digital signal by the A / D conversion unit, and the audio data converted into the digital signal is recorded. The digital signal sent from the A / D converter is processed and converted by the audio signal processor, and the processed digital signal is converted to an analog signal by the D / A converter. The analog signal sent from the D / A converter is amplified by the audio output amplifier, and the analog signal amplified by the audio output amplifier is output from the speaker 102a or an audio cable (not shown).

  The microphones 102bL and 102bR are silicon microphones and are mounted on the FPC 102. The microphones 102bL and 102bR have four terminals and are connected to the pattern on the FPC 102 by mounting with solder. The FPC 102 is a single-sided flexible printed circuit board, and has a structure in which a copper pattern is wired on a base film made of polyimide, and the surface thereof is covered with a cover lay made of polyimide.

  The wiring of the microphones 102bL and 102bR will be described. As shown in FIG. 8B, a ground signal line 201 and an output signal line 202 are connected to the microphone 102bL. A power signal line 203 for driving them is connected to the microphone 102bL and the microphone 102bR. A ground signal line 204 and an output signal line 205 are connected to the microphone 102bR. These signal lines are connected to the terminals of the microphones 102bL and 102bR by soldering. These terminals correspond to the ground signal terminals 201a and 201b, the output signal terminal 202a, and the power signal terminal 203a of the microphone 102bL. Furthermore, the ground signal terminals 204a and 204b, the output signal terminal 205a, and the power signal terminal 203b of the microphone 102bR correspond to this.

  As shown in FIGS. 8A and 8B, a plus signal line 206 and a minus signal line 207 of the speaker 102a are provided as wiring for the speaker 102a. As shown in FIG. 8A, the FPC 102 is directly soldered to the speaker 102a at a soldering point 208. The attaching portion 208a of the FPC 102 is attached to the speaker 102a with double-sided tape, and is configured so as not to apply a load to the soldering portion 208 even when a load is applied to the speaker 102a during assembly work or the like.

  The operation system signal line group 209 includes signal lines of the power switch 102d, the release switch 102c, and the zoom switch 102e. A check pad group 210 is formed by exposing the signal lines of the speaker 102a and the microphones 102bL and 102bR in a circular shape. The check pad group 210 detects each signal of the speaker 102a and the microphones 102bL and 102bR by applying a probe, and can confirm whether or not there is a disconnection due to mounting failure in the unit assembled state. Further, it can be checked whether the left and right microphones 102bL and 102bR of the stereo microphone have a sensitivity difference equal to or greater than a specified value. When a plurality of speakers 102a are provided to form a stereo speaker, the left and right sound pressure levels can be adjusted. By providing a check pad, adjustment is possible without performing assembly.

  As shown in FIG. 8B, the signal lines related to the speaker 102a and the microphones 102bL and 102bR are arranged in parallel. However, since the signal line adjacent to the plus-side signal line 206 of the speaker 102a is the ground signal line 201 of the microphone 102bL, it is avoided that the noise of the signal of the speaker 102a is superimposed on the output signal line 202 of the microphone 102bL. Has been.

  Further, the power signal line 203 is wired between the output signal line 202 and the output signal line 205, thereby preventing the output signals from affecting each other. Also, since the power signal line 203 is a common power supply line for the left and right microphones, the power signal line 203 can be used on a single-sided flexible printed circuit board by turning around the center of the left and right output signal lines 202 and 205. It is easy to wire. In addition, by sharing the power source even in the single-sided flexible printed circuit board, the number of pins of the inter-board connector 102g when connecting to the main wiring board 106 can be reduced, thereby reducing the cost.

  The ground signal line 204 prevents noise such as static electricity from the operation system from being superimposed. The ground signal line 201 and the ground signal line 204 are wired on the same surface, and these prevent the introduction of noise from the outside.

  The speaker 102a is folded back at the folding position L1 shown in FIG. The speaker 102a can be disposed between the microphones 102bL and 102bR by folding back. When the speaker 102a is assembled to the holding member 104 by providing the folding, the FPC 102 has a margin, so that the assembly is easy. Further, it is not necessary to assemble the speaker 102a and the microphones 102bL and 102bR at a time, and it is only necessary to assemble the speaker 102a after folding the FPC 102 after the microphones 102bL and 102bR are assembled.

  Since wiring is performed in this way, the FPC 102 on which the speaker 102a and other operation systems are mounted can be configured as a single-sided flexible printed circuit board while suppressing noise superposition on the output signal lines 202 and 205. Thereby, it leads to a cost reduction and assembly property can also be improved.

  As described above, in this embodiment, the speaker 102a and the microphone 102b are closely attached to the back surface 101g of the upper plate portion 11 of the front cover 101 through separate components. As a result, it is possible to ensure close contact with the front cover 101 regardless of the assembled state of each other. In any case, the following inconvenience is assumed when a structure in which the front cover 101 is brought into close contact with the same integral member (for example, the holding member 104) is assumed. For example, it may occur that the microphones 102bL and 102bR are attached to be inclined, and the portion of the holding member 104 around the microphones 102bL and 102bR cannot be sufficiently adhered to the front cover 101. In this case, the portion of the holding member 104 around the speaker 102a may not be sufficiently adhered to the front cover 101.

  As in this embodiment, the sound insulation of the speaker 102a and the microphone 102b is not performed as an integral part, but the influence of each manufacturing error or assembly error on each other in the assembled state is reduced by insulating the sound with separate members. Become. Moreover, since it shields with another member, there also exists an advantage that a mutual vibration is not transmitted directly. Therefore, sound insulation can be performed without depending on each assembled state, and sound quality can be improved.

  According to the present embodiment, since the speaker 102a and the microphone 102b are held by the integral holding member 104, the number of assembling steps can be reduced and the assembling performance can be improved as compared with holding them separately. Further, since the sound insulation of the microphone 102b is performed by the protrusion 104c which is a part of the elastic holding member 104 itself, it is not necessary to provide a member dedicated to sound insulation, and the number of parts is reduced, leading to a cost reduction. Therefore, the assemblability of the speaker 102a and the microphone 102b can be improved, and the sound insulation between them can be ensured with few parts.

  Also, by making the hardness different between the elastic member 102aa and the holding member 104, it becomes difficult for the deformation due to manufacturing error or assembly error to be transmitted, and the adhesion failure of the elastic member 102aa to the protruding portion 104c hardly occurs. Thereby, the assemblability and sound insulation of the speaker 102a and the microphone 102b can be further improved.

  The microphone hole 101bL, the speaker hole 101a, and the microphone hole 101bR are adjacently opened on the surface 101h. Correspondingly, the microphones 102bL and 102bR are disposed on both sides of the speaker 102a. In this way, the components arranged close to and adjacent to each other usually have a great influence on each other in the assembled state, and the influence of sound is also great. Therefore, the present invention is particularly effective for such an arrangement.

(Second Embodiment)
In the second embodiment of the present invention, as compared with the first embodiment, the portion of the protrusion 104c of the holding member 104 that abuts and engages with the back surface 101g of the upper plate portion 11 of the front cover 101. The configuration is different. Since other configurations are the same as those of the first embodiment, different components will be mainly described.

  FIG. 9 is a partial cross section taken along the line AA of FIG. 1 showing a state in which the FPC 102, the sheet metal 103, and the holding member 104 are assembled to the front cover 101 in the digital camera as the electronic apparatus according to the second embodiment. FIG.

  As shown in FIG. 9, a groove 104d is formed deeper than the one in the first embodiment between the two protruding ridges 104c. The groove 104d is formed over the entire circumference. Projecting portions 101j are formed to project from the back surface 101g of the upper plate portion 11 of the front cover 101 at positions corresponding to the respective grooves 104d. Similar to the groove 104d, the protruding portion 101j also has a substantially rectangular enclosing shape (frame shape).

  When the FPC 102, the sheet metal 103, and the holding member 104 are assembled to the front cover 101, and the protruding portion 104c comes into close contact with the back surface 101g, the protruding portion 101j enters and fits into the corresponding groove 104d. Thereby, since the degree to which the protrusion 104c and the groove 104d are in close contact with the back surface 101g is increased, the shielding state of the spaces S1L and S1R is increased. Therefore, according to the present embodiment, the sound quality of the microphones 102bL and 102bR can be further improved. Since the protruding portion 101j can be formed integrally with the front cover 101, the number of parts does not increase.

  In each of the above embodiments, the double structure adopted for the protrusion 104c may also be adopted for the upper part of the elastic member 102aa. Moreover, you may employ | adopt the structure which the groove | channel 104d and the protrusion part 101j in 2nd Embodiment fit to the upper part of elastic member 102aa.
