  Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. In addition, not all the combinations of features described in the embodiments are essential for the solving means of the invention.

  FIG. 1 schematically illustrates an example of the appearance of a camera 100 according to an embodiment. The camera 100 is a single-lens reflex camera as an example of an imaging device. The camera 100 includes a command dial 20, a vertical position command dial 10, a vertical position operation button 40, a multi-selector 30, a display unit 80, an eyepiece unit 70, and a lens unit 120.

  The command dial 20, the vertical position command dial 10, the vertical position operation button 40, the multi selector 30, the display unit 80, and the eyepiece unit 70 are opposite to the side on which the lens unit 120 is mounted in the camera 100 body. Is provided. The command dial 20, the vertical position command dial 10, the multi-selector 30, and the vertical position operation buttons 40 are examples of operation members that receive user operations on the camera 100.

  The vertical position command dial 10 is rotated by a user operation. The camera 100 specifies a user instruction based on the amount of rotation of the vertical position command dial 10. For example, the camera 100 specifies the shutter speed or the like according to the rotation amount of the vertical position command dial 10. For example, the camera 100 stores a rotation amount and a shutter speed value in association with each other. Then, when the vertical position command dial 10 is rotated, the camera 100 changes the shutter speed to a value corresponding to the rotation amount. The rotation surface of the vertical position command dial 10 is provided so as to be substantially orthogonal to the horizontal direction of the camera 100. When the user holds the camera 100 in the vertical position, the user can easily operate the vertical position command dial 10 with a finger.

  The command dial 10 for vertical position is provided so that a part protrudes from the opening provided in the housing | casing 90. FIG. In the present embodiment, the camera 100 has a speaker provided in the housing 90 so that sound is emitted from the opening. According to the camera 100, the opening provided for the vertical position command dial 10 can be used as a sound emitting part to the outside.

  The vertical position operation button 40 is a button member that is pushed in by a user operation. For example, the camera 100 performs an automatic focus adjustment (AF) operation in response to the pressing of the vertical position operation button 40. When the user holds the camera 100 in the vertical position, the user can easily operate the vertical position operation button 40 with a finger.

  The command dial 20 is a command dial for horizontal position and has the same function as the command dial 10 for vertical position. The rotation surface of the command dial 20 is provided substantially parallel to the lateral direction of the camera 100. The user can easily operate the command dial 20 with a finger when the camera 100 is held in a horizontal position.

  The multi selector 30 is provided so that it can be pushed in by a user operation. The multi-selector 30 has a plurality of pushing positions where the user can push in. The camera 100 specifies a user instruction based on the pushed position. For example, the camera 100 sets a focus point based on the push position of the multi selector 30. For example, the camera 100 stores a plurality of push-in positions corresponding to a plurality of directions in advance. When the multi-selector 30 is pushed in, the camera 100 moves the focus point or the like in a direction corresponding to the pushed-in position. The multi-selector 30 may be provided so as to be rotatable like the vertical position command dial 10 and the command dial 20. In this case, the camera 100 may specify various user instructions according to the rotation amount of the multi-selector 30.

  The display unit 80 may be a monitor such as a liquid crystal. The display unit 80 displays images such as moving images and still images. When image data and audio data are recorded correspondingly, the camera 100 causes the speaker to output sound based on the sound data while displaying an image based on the image data on the display unit 80. Further, the user can visually recognize the subject through the eyepiece unit 70. The user can check the composition via the eyepiece unit 70.

  FIG. 2 is a schematic sectional view of a portion where the vertical position command dial 10 is provided. This figure is a schematic view of the longitudinal position command dial 10 cut along a cross section including the rotation axis.

  The housing 90 is formed with an opening 110 for providing the vertical position command dial 10. A part of the vertical position command dial 10 protrudes from the opening 110. The user can rotate the vertical position command dial 10 by operating a portion protruding from the housing 90.

  The fixing member 270 and the sound hole member 200 are provided in the housing 90. The internal space of the housing 90 is substantially sealed by the housing 90, the fixing member 270, the sound hole member 200, and the vertical position command dial 10. In particular, the space formed by the opening 110 is at least partially defined by the sound hole member 200. Thus, the sound hole member 200 defines at least a part of a space communicating with the opening 110 formed in the housing 90.

  The fixing member 270 holds the command dial 10 for vertical position so as to be rotatable. The fixing member 270 supports the vertical position command dial 10 on one axis. The fixing member 270 has a through hole that receives the rotation shaft of the vertical position command dial 10. Of the protruding portion that provides the rotation axis of the command dial for vertical position 10, the portion that has passed through the through hole is fixed by a fixing member 280 that slides relative to the fixing member 270. Thereby, the command dial 10 for vertical positions is fixed to the fixing member 270 so as to be rotatable.

  The sound hole member 200 is provided facing the vertical position command dial 10. The sound hole member 200 has an outer surface that is a surface facing the vertical position command dial 10 and an inner surface on which the speaker 230 is provided. The outer side surface is a surface facing the rotation surface of the vertical position command dial 10. The sound hole member 200 has a plurality of sound holes 202 formed on the outer surface. Specifically, the sound hole member 200 has a plurality of sound holes 202 penetrating from the outer surface to the inner surface.

  The sound hole member 200 has a rib 204 that fixes the speaker 230 to the inner surface. The sound hole member 200 has ribs 204 around the area where the sound holes are formed. The rib 204 forms a housing portion that houses the speaker 230. The sound emitting surface of the speaker 230 is pressed against the sound hole member 200 by the pressing member 240 and accommodated in the accommodating portion. When the speaker 230 is accommodated in the accommodating portion, the sound emitting surface of the speaker 230 is located at a position facing the region where the plurality of sound holes 202 are formed in the sound hole member 200.

  On the sound emitting surface of the speaker 230, a drip-proof net 220 having sound permeability and drip-proof properties is provided. The drip-proof net 220 is in close contact with the speaker 230 by the cushion member 210. The drip-proof net 220 and the cushion member 210 will be described later.

  The sound emitted from the speaker 230 passes through the drip-proof net 220 and the sound hole 202 and is emitted from the opening 110 to the outside. For this reason, the opening 110 for the command dial 10 for the vertical position also functions as a sound emitting unit that emits sound from the speaker 230 to the outside. For this reason, it is not necessary to provide the housing 90 with a sound emitting unit dedicated to the speaker 230.

  As shown, the outer surface of the sound hole member 200 provides a surface that defines a space that extends from the opening 110 into the housing 90. A part of the vertical position command dial 10 is accommodated in the space. Specifically, the outer surface of the sound hole member 200 defines a part of the inner surface of the substantially concave space that communicates with the outside through the opening 110. The sound hole member 200 functions as a structural member of the camera 100 together with the housing 90. Further, the penetration direction of the sound hole 202 formed in the sound hole member 200 is substantially orthogonal to the opening 110. For this reason, it is not necessary to provide the speaker 230 facing the opening 110. For this reason, the speaker 230 can be relatively freely arranged in the housing 90.

  FIG. 3 is a diagram for schematically explaining the assembly of the speaker 230. The composite unit 300 has a function of accepting a user operation and a function of outputting sound in the camera 100. The composite unit 300 is an example of a detection unit that detects the amount of rotation of the vertical position command dial 10, the fixed member 270 and the fixed member 280, the sound hole member 200, the speaker 230, the pressing member 240, and the vertical position command dial 10. As a rotary encoder 290.

  The sound hole member 200 has a fitting portion 206 that fits into a hook-like fitting portion 246 provided on the pressing member 240. By fitting the fitting portion 246 into the fitting portion 206, the pressing member 240 presses the speaker 230 against the sound hole member 200 from the surface opposite to the sound emitting surface of the speaker 230. Thereby, the sound emitting surface of the speaker 230 is positioned at a position facing the inner surface having the sound hole 202 in the rib 204.

  FIG. 4 schematically shows the composite unit 300 in a state where the speaker 230 is assembled. The fixing member 270 is fixed to the housing 90 with the screwing portion 400. Thereby, the entire composite unit 300 is fixed to the housing 90.

  FIG. 5 schematically shows the composite unit 300 provided in the housing 90. FIG. 6 schematically shows the composite unit 300 viewed from a direction parallel to the rotation surface of the vertical position command dial 10.

  As shown in FIG. 1 and the like, the vertical position command dial 10 is provided at the lower right side of the camera 100. The right side portion of the camera 100 has a curved shape that allows the user to easily hold the camera 100 when held in a horizontal position. When the camera 100 is held in a horizontal position, the lower right portion of the camera 100 is held by the user's palm. For this reason, except for the operation member for the vertical position, there are not many operation members on the lower right side of the camera 100. For this reason, a margin is created in the internal space of the housing 90 at the lower right side of the camera 100. In the camera 100, the speaker 230 can be provided in the space on the lower right side of the camera 100. Therefore, the space inside the housing 90 can be used effectively.

  In addition, from the viewpoint of user operability and design, the outer surface of the camera 100 is often formed with a curved surface. According to the camera 100, it is not necessary to provide a speaker-specific flat portion on the outer surface of the camera 100. For this reason, the outer surface shape of the camera 100 can be determined without being greatly restricted by the mounting position of the speaker. Further, in the camera 100, a relatively large speaker 230 can be applied as compared with the case where the speaker is provided facing the outer surface of the camera.

  FIG. 7 shows an exposed portion of the vertical position command dial 10. FIG. 8 schematically shows a cut surface taken along the line XX of FIG. The speaker 230 includes an electrode 238 for inputting an audio signal. The electrode 238 is electrically connected to an audio signal output unit that outputs an audio signal and a wiring that carries the audio signal. The speaker 230 generates sound waves by vibrating air based on an audio signal as an electric signal input from the electrode 238.

  FIG. 9 schematically shows a cut surface taken along the YY section of FIG. FIG. 10 shows an enlarged view of a portion including the Z portion of FIG. The drip-proof net 220 is provided in contact with the sound emitting surface of the speaker 230. The cushion member 210 is provided between the inner surface of the sound hole member 200 and the drip-proof net 220. The cushion member 210 may be an annular member provided corresponding to the periphery of the speaker 230. The cushion member 210 is in close contact with the sound hole member 200 while being elastically deformed by the speaker 230 being pressed by the pressing member 240. Further, the cushion member 210 causes the drip-proof net 220 to be in close contact with the speaker 230 at least around the sound emitting surface of the speaker 230 when the speaker 230 is pressed by the pressing member 240. Thereby, water can be prevented from entering the internal space provided with the speaker 230 through the opening 110 and the sound hole 202.

  Further, the cushion member 210 can form an air chamber between the sound emitting surface of the speaker 230 and the sound hole member 200. Compared with the case where no air chamber is provided, the sound quality of the sound emitted from the opening 110 can be improved.

  In the example of this figure, the cushion member 210 is provided between the sound hole member 200 and the drip-proof net 220. However, a drip-proof net may be provided between the sound hole member 200 and the cushion member. For example, a drip-proof net may be provided in contact with the inner surface of the sound hole member 200. Then, a cushion member may be provided around the sound emitting surface of the speaker 230, and the drip-proof net 220 may be in close contact with the sound hole member 200 with the cushion member.

  Thus, the drip-proof net 220 is provided between the speaker 230 and the inner surface of the sound hole member 200. The cushion member 210 is provided between the speaker 230 and the inner surface of the sound hole member 200 at a position corresponding to the peripheral portion of the speaker 230. For this reason, the sound quality of the emitted sound can be enhanced while maintaining the drip-proof effect.

  In the above description, the air chamber is provided between the speaker 230 and the sound hole member 200 by the cushion member 210. However, an air chamber may be formed between the sound emitting surface of the speaker 230 and the inner surface of the sound hole member 200 by providing a recess on the inner surface of the sound hole member 200. In addition, the vertical position command dial 10 may be provided with a groove portion that provides a sound path for the sound emitted from the speaker 230. For example, you may have one or more groove | channels formed toward the periphery of the command dial 10 for vertical positions from the position of the rotating shaft of the command dial 10 for vertical positions.

  In the above description, the sound hole member 200 has a plurality of sound holes 202. However, the sound hole member 200 may have one sound hole. In other words, the sound hole member 200 may have one or more sound holes.

  In the above description, the speaker 230 is provided corresponding to the vertical position command dial 10. However, in place of the command dial 10 for the vertical position, members similar to the sound hole member 200, the cushion member 210, the drip-proof net 220, and the speaker 230 may be provided corresponding to the command dial 20 to form a composite unit. Further, in addition to the composite unit 300, members similar to the sound hole member 200, the cushion member 210, the drip-proof net 220, and the speaker 230 may be provided corresponding to the command dial 20 to form a further composite unit.

  In this case, the speaker included in one composite unit may be a speaker that outputs right (R) sound, and the speaker included in the other composite unit may be a speaker that outputs left (L) sound. Thereby, stereo sound can be output. Note that the sound output from the speaker is not limited to the right sound and the left sound. For example, high-frequency sound and low-frequency sound may be output. The number of audio channels to be output is not limited to 2ch. Three or more composite units may be provided and applied as an audio output unit of 3ch or more.

  The members for providing the speakers are not limited to the vertical position command dial 10 and the command dial 20. A speaker can be provided corresponding to various operation members such as the multi selector 30 and the vertical position operation button 40. That is, operation members of various mechanical operation methods such as a dial type, a button type, and a slide type can be applied as an operation member provided with a corresponding speaker. Further, the type of the operation member is not limited to the above example as long as it is a member that can use the gap between the case 90 and the sound output port. In addition to the operation member, speakers may be provided corresponding to various members having a gap with the housing 90. Further, a speaker may be provided on the operation member itself such as the vertical position command dial 10.

  In the above description, the speaker 230 as an example of the acoustic device has been described. However, as the acoustic device, in addition to the speaker 230, a microphone can be exemplified. That is, similarly to the speaker 230, a microphone may be provided corresponding to a command dial or the like. For example, when a microphone is provided corresponding to the vertical position command dial 10 instead of the speaker 230, the opening 110 can be used as a sound opening. If it is a microphone for recording a user's voice, like the speaker 230, you may provide corresponding to the operation member of the side by which the lens unit 120 is not mounted | worn. In the case of a microphone or the like that collects environmental sounds, a microphone may be provided corresponding to the operation member on the side where the lens unit 120 is mounted, such as a command dial provided on the front surface. It was necessary to provide the housing with a sound passing portion that was essentially dedicated to the acoustic device.

  In the present embodiment, the camera 100 that is a single-lens reflex camera is illustrated as an example of the imaging apparatus. However, as an imaging device, a single-lens reflex camera as an interchangeable lens camera, a mirrorless camera, a compact digital camera which is an example of a non-lens interchangeable camera, a video camera, a mobile phone with an imaging function, an imaging function equipped Various electronic devices having an imaging function, such as portable information terminals and entertainment devices such as game devices with an imaging function, can be applied. Note that the electronic device is not limited to the imaging device, and various electronic devices such as a recording device such as an IC recorder, a mobile phone, a portable information terminal, a game device, a video device such as a television, a recording device, and a digital photo frame can be applied. Can be targeted.
