  In addition, when the user grips the digital camera body, a grip portion may be provided which can hold the thumb by placing the thumb on the digital camera body adjacent to the display unit.

  When the operation member is disposed in the grip portion, an erroneous operation occurs when the user grips, so the operation portion or the like is not disposed, and a space tends to exist inside the grip portion.

  And in order to utilize the space effectively, acoustic devices, such as a speaker, may be arranged.

  However, for example, when a speaker is disposed and disposed so as to penetrate the sound hole to the back side, it becomes a grip portion. As a result, at the time of use, the user is blocked by the thumb and the sound can not be emitted well.

  Therefore, it is conceivable to provide a sound output hole in the wall surface of the display unit unit storage unit on the display unit unit side and to emit sound from the gap between the display unit and the storage unit.

  It has been proposed that the sound from the speaker is guided to the hinge portion by providing a gap (Patent Document 1).

  In this proposal, the sound of the speaker can be emitted to the opposite side of the surface provided with the sound emission hole through the gap with the hinge portion.

  Moreover, what made the holding part and sound emission compatible by making a holding part into convex shape and providing a sound emission hole in the side is proposed (patent document 2).

  In this proposal, even if the user places his thumb on the convex portion, the sound emission hole is on the side, so the thumb does not block it.

  As shown to Fig.5 (a), the said speaker 20 is arrange | positioned directly under the Z direction of the holding member 16 by the side of a back.

  Between the holding member 16 on the back side and the speaker 20, a receiving portion 11b extending from the side wall 11a in the X direction and connected to the wall of the sound output hole 17 is provided.

  The receiving portion 11 b is provided with a substantially circular through hole substantially coaxial with the speaker 20 in the Z direction.

  A substantially annular elastic member 21 is disposed between the receiving portion 11 b around the through hole and the speaker 20.

  Further, a dustproof sheet member 22 such as a non-woven fabric is disposed between the elastic member 21 and the speaker 20 so as to cover the speaker 20.

  It is considered that dust and the like from the outside do not intrude into the speaker 20.

  And the speaker 20 is hold | maintained at the said receiving part 11b by the holding member 23 so that the elastic member 21 may be crushed toward the receiving part 11b.

  Here, although the speaker 20 is circular, it may have any shape and may be firmly held, and the shape of the elastic member may not be annular as long as the speaker 20 can emit sound.

  A slope or curved first reflection portion 16 a is provided at a portion of the rear side gripping member 16 facing the speaker 20 in the Z direction.

  The sound output from the speaker 20 is reflected in the direction of the sound emission hole 17 by the first reflection portion 16a.

  The reflected sound passes through the sound path 19 formed by the receiving portion 11 b and the rear side gripping member 16, and is output from the sound output hole 17 to the first groove 8 (a).

  FIG. 5B is a cross-sectional view of the vicinity of the sound emission hole 17 viewed from the same direction of FIG. 1B in which the display unit 9 can be viewed by the user.

  FIG. 5 is a cross-sectional view of the first groove 8 (a) from the upper side in the Y direction in FIG. 1 (b) toward the notch 7;

  As shown in FIG. 5B, as described above, part of the sound output from the sound output hole 17 leaks from the gap between the storage unit 11 and the display unit 8.

  However, since the first groove 8 a and the side wall 11 a constitute a space larger than the above-described gap and communicate with the notch 7, a louder sound is output from the notch 7.

  FIG. 6 is a cross-sectional view of the vicinity of the sound output hole 17 as viewed from the same direction in FIG. 2 (a) in which the display unit 9 is inverted from FIG. 1 (b).

  FIG. 3 is a cross-sectional view of the first groove 8 (b) from the upper side in the Y direction in FIG. 2 (a) to the notch 7;

  As shown in FIG. 6, the second groove 8 (b) is at the position where the sound release hole 17 faces.

  Part of the sound output from the sound release hole 17 leaks from the gap between the storage unit 11 and the display unit 8.

  However, the second groove 8 b and the side wall 11 a form a space larger than the above-mentioned gap, and since the space is in communication with the notch 7, a louder sound is output from the notch 7.

  Here, a state in which the first groove portion 8 (a) is opposed to the sound output hole 17 is a larger space than a state in which the second groove portion 8 (b) is opposed to the sound output hole 17. Is configured.

  That is, in the storage state of the display unit 8, the user can hear a louder sound in the state in which the display unit 9 in FIG. 5B can be viewed.

  Therefore, the user can hear a larger voice and operation sound when playing back a moving image or when setting for shooting.

  However, when shooting while the user looks into the finder 15, the face approaches the sound release hole 17.

  Therefore, the operation sound when the release button 2 is pressed may feel uncomfortable if the volume is as high as that at the time of moving image reproduction.

  Therefore, by inverting the display unit 8 around the second axis 10b and storing it in the storage unit 11, the operation sound when the release button 3 is pressed becomes a smaller sound than that during moving image reproduction.

  According to this embodiment, the user can hear a larger sound when playing back a moving image.

  Therefore, when photographing using the finder 15, it is possible to reduce the operation sound of the release button 3 to a certain level without adjusting the volume each time.

(An example of the present embodiment)
FIG. 7 is an example of this embodiment, and is a cross-sectional view similar to FIG. 5 (b).

  As shown in FIG. 7, the second reflecting portion 30 is provided on the wall surface of the first groove portion 8 (a) on the upper side in the Y direction.

  The reflecting portion 30 gradually changes toward the notch 7 toward the bottom surface of the first groove 8 (a) in the X direction from the position facing the Y-direction upper end face of the sound emission hole 17 It is a slope.

  Therefore, the sound output from the sound release hole 17 can be reflected toward the notch 7.

  Here, although the second reflection portion 30 is a slope, it may be a curved surface as long as the sound output from the sound emission hole 17 can be reflected toward the notch 7.

  Thereby, the sound output from the sound output hole 17 can be more efficiently introduced to the notch 7.

  Although the display unit having the two-axis hinge unit has been described in the present embodiment, a single-axis hinge unit may be used, and the present invention can be applied to all units in which the display unit is movable.
