Further, the sound generating surface 53 of the speaker 52 is pressed against the inner surface of the sound generating unit 36 with a predetermined pressing force by the urging force of the leaf spring members 58 and 58. Thereby, the speaker 52 is attached to the storage portion 56 without dropping from the storage portion 56 of the front cover 12.

  Therefore, according to the connection structure shown in FIG. 3, the speaker 52 and the substrate 54 can be easily and reliably attached to the camera body without using lead wires.

  FIG. 4 shows a second embodiment of the connection structure between the speaker 52 and the substrate 54 built in the camera 10, and the same or similar members as those in the first embodiment shown in FIG. The same reference numerals are used for explanation.

  According to the connection structure of FIG. 4, the speaker 52 and the substrate 54 are connected by a floating connector 64 including a plug 60 and a receptacle (jack) 62. The plug 60 is attached to a predetermined position of the substrate 54, and the receptacle 62 is attached to the speaker substrate 66.

  As shown in FIG. 5, the plug 60 includes a plug main body 68 fitted and connected to the receptacle 62, and a base portion 70 fixed to the substrate 54. The base portion 70 and the plug main body 68 are in contact with each other. Is conducted by. Further, a convex portion 72 is formed on the upper surface of the base portion 70, and the convex portion 72 is loosely fitted with a gap C in a concave portion 74 formed on the lower surface of the plug body 68. Therefore, the plug main body 68 is slidably attached to the base portion 70 by the gap C (2C). In other words, the plug main body 68 is attached to the substrate 54 so as to be slidable in the straight direction. When the convex portion 72 is formed at the center of the upper surface of the base portion 70, the plug body 68 can also move in the rotational direction around the convex portion 72.

In addition, since the direct connection type connector 64 including the plug 60 and the receptacle 62 is employed, the influence of noise is reduced. In the embodiment, the plug 60 side is moved with respect to the substrate 54. However, the receptacle 62 side may be moved with respect to the speaker substrate 66.

  FIG. 6 shows a third embodiment of the connection structure between the speaker 52 and the substrate 54 built in the camera 10, and the same or similar members as those in the first embodiment shown in FIG. The same reference numerals are used for explanation.

  According to the connection structure of FIG. 6, the speaker substrate 76 provided on the speaker 52 is directly connected to the land 78 of the substrate 54 by solder. Further, in the storage portion 56 of the front cover 12, for example, a pressing piece 80 formed integrally with the plastic front cover 12 is formed by cutting out a part of the storage portion 56. The pressing piece 80 is cantilevered on the front cover 12 as shown in FIG. 7, and a hemispherical abutting portion 82 is formed at the tip thereof.

  According to the connection structure shown in FIGS. 6 and 7, when the speaker 52 directly connected to the substrate 54 is inserted into the storage portion 56, the abutting portion 82 of the pressing piece 80 is pressed against the back surface of the speaker substrate 76. As a result, the base 81 is elastically deformed toward the right in FIG. When the speaker 52 is completely inserted into the storage portion 56, the speaker 52 receives a biasing force in the left direction of FIG. 7 through the contact portion 82 due to the elastic restoring force of the pressing piece 80. Therefore, the sound generating surface 53 of the speaker 52 is pressed against the back surface of the sound generating portion 36 of the front cover 12. That is, even if there is a gap between the storage unit 56 and the speaker 52, the speaker 52 is positioned on the back surface of the sound generation unit 36 by the urging force of the pressing piece 80. Therefore, even after the speaker 52 is fixed to the substrate 54, the speaker 52 can be attached to a normal position.

  In the embodiment, the connection structure of the speaker 52 is exemplified, but the present invention is not limited to this, and the same connection structure can be applied to the microphone. Further, although the speaker 52 and the microphone, which are acoustic parts, are exemplified as the electronic parts, the present invention is not limited to this, that is, the voltage and current are amplified and controlled without using mechanical or other non-electrical methods. In addition, the connection structure of the present invention can be applied to any electronic component (for example, a solid-state device such as the strobe light control sensor 22) that switches current and voltage without a mechanical switch.

  Furthermore, in the embodiments, the digital camera has been exemplified, but the present invention is not limited to this. For example, the present invention is also applied to electronic parts of multifunctional portable electronic communication devices such as a camera-equipped mobile phone and a PDA (Personal Digital Assistant).
