For example, the structure which arrange | positions a speaker to the side surface of the horizontal direction of an apparatus main body can also be considered. In the electronic device adopting such a configuration, when the configuration of the conventional example of the above-mentioned Patent Document 1 is adopted, a sound conducting member is separately required, so that an efficient component configuration such as miniaturization of the electronic device is achieved. In particular, there was a problem.

  In view of the above-described conventional problems, the present invention realizes an efficient component configuration that can efficiently guide the sound generated from a speaker to the outside without adding a separate component such as a sound guide member and can be downsized. It is an object to provide an electronic device that can be used.

  In order to achieve the above object, an electronic device of the present invention is an electronic device having a speaker and an exterior member provided with a strap member in which a recess is formed on an exterior side surface and a strap is attached to the recess. A sound emitting hole is formed at the bottom of the concave portion, and the speaker is arranged so that the sound emitting hole faces the sound emitting surface of the speaker.

  According to the present invention, it is possible to efficiently transmit the sound generated from the speaker to the outside without newly increasing the number of components such as a sound guide member, and to realize an efficient component configuration that can be downsized. It becomes possible.

  Then, after the side cover 8 is assembled in the battery box 14, the front cover 1 and the rear cover 2 are assembled and fixed with screws (not shown), thereby completing the assembly of the digital camera body.

  Next, the arrangement configuration of the side cover 8, the strap member 9, and the speaker 13 after assembly will be described with reference to FIG.

  FIG. 5 is a cross-sectional view of an arrangement site of the strap member 9 and the speaker 13 in the digital camera of the present embodiment, and is a cross-sectional view cut in the directions of arrows P and P ′ in FIG.

  As described above, when the side cover 8, the strap member 9, and the speaker 13 are incorporated in the digital camera body, the speaker 13 is housed in the cylindrical shape 14a of the battery box 14 as shown in FIG.

  The strap member 9 is provided with a plurality of sound emission holes 9b for transmitting the sound generated from the speaker 13 to the outside. Since the speaker 13 is arranged so that the sound emission surface of the speaker 13 faces the plurality of sound emission holes 9b, the sound generated from the speaker 13 is emitted to the outside through the sound emission holes 9b. The side cover 8 is incorporated in the hole 8a through the strap ring 9a of the strap member 9. The hole 8a of the side cover 8 is formed with a recess 8b for passing a strap string, and the recess 8b has a pair of left and right shapes around the strap ring 9a of the strap member 9. The sound generated from the speaker 13 travels through the sound emission hole 9b, and is further transmitted to the outside while being reflected and amplified by the recess 8b.

  When passing the strap string, the strap string goes down along the recess 8b, passes through the hole in the strap ring 9a, and goes out along the opposite recess 8b again. In this way, the photographer can attach the strap string to the digital camera body.

  The sound emission hole 9b of the strap member 9 is formed by penetrating a convex portion 9c formed integrally with the base 9d of the strap member 9. The convex shape portion 9c has a stepped convex shape from the bottom surface of the lower end of the concave portion 8b, whereby the opening portion of the sound emitting hole 9b is located at a position protruding from the hole portion 8a. Therefore, even if dust or the like from the outside enters along the recess 8b, it is possible to prevent the sound from entering the sound emitting hole 9b, and to transmit sound well without blocking the sound emitting hole 9b with dust or the like. it can.

<Operation and effect according to this embodiment>
Next, operations and effects of the digital camera according to the present embodiment configured as described above will be described with reference to FIG.

  FIG. 6 is an image diagram when the digital camera in the present embodiment is gripped.

  As shown in FIG. 6, the speaker 13 and the strap member 9 are disposed on a surface (grip surface) on the side where the photographer holds the digital camera body, and are disposed at a substantially central portion of the grip surface. In other words, the direction in which the strap member 9 is exposed and the direction in which the sound emitted from the speaker 13 is emitted are on the grip surface side.

  With this configuration, when the photographer operates the digital camera body while attaching a finger to the release button 7, the bulge of the palm is positioned substantially beside the strap member 9. Since the bulge of the palm is positioned beside the strap member 9, the sound emitted from the speaker 13 is first transmitted through the sound emission hole 9b of the strap member 9, reflected by the concave portion 8b of the side cover 8, and amplified. It is transmitted to. Furthermore, the sound is transmitted to the photographer side by reflecting on the palm of the hand. In this way, the sound generated from the speaker 13 can be efficiently guided to the outside and transmitted to the photographer.

  Moreover, since the part from which the sound from the speaker 13 is emitted to the outside is disposed at the center of the grip side surface, the part is not completely covered with the hand when gripped, and it is difficult to block the sound. For example, if a sound emitting part is disposed below the side of the grip, for example, the palm is covered with the palm when gripped, and the sound is blocked. In addition, when a sound emitting part is disposed on the upper side of the grip side, the swollen hand is located at the center of the side when the finger or palm is gripped.

  As described above, in the present embodiment, by arranging the speaker 13 immediately below the strap member 9, the sound emission hole 9b of the speaker 13 is formed in the hole 8a of the side cover 8 for passing the strap string. Can be deployed. As a result, the sound generated by the speaker 13 functions as a sound guiding member through the hole 8a for passing the strap string, and acts as if it is a horn shape of a loudspeaker. It is possible to tell. Furthermore, since the strap member 9 is disposed at the approximate center of the grip surface of the camera, the sound can be efficiently transmitted to the photographer. Further, the appearance design is improved, and for example, it is possible to provide an opening of the external terminal in a vacant space.

  Further, by using the hole 8a for passing the strap string as a sound guide member, the number of parts can be reduced without using a separate part, and the depth of the hole 8a for allowing the speaker 13 to pass the strap. The camera can be downsized.

  As described above, in this embodiment, even when the speaker 13 is disposed where the camera extends in the horizontal direction (dead space) due to the widening of the LCD, an efficient component configuration can be adopted. This can contribute to the reduction of the number of points and the miniaturization.

  In the above-described embodiment, a digital camera has been described as an example of an electronic device. However, the present invention is not limited to a digital camera and may be an electronic device such as a mobile phone.
