Description

  The present invention relates to an imaging device including a speaker.

  Many imaging apparatuses capable of shooting a moving picture have a built-in speaker for listening to sound during reproduction. When reproducing with an imaging device, it is assumed that the image is reproduced on the go or outdoors. Therefore, a speaker capable of outputting a necessary and sufficient volume capable of recognizing reproduced sound even when there is ambient noise or the like, for example, a speaker having a certain large diameter is required.

  As the image pickup apparatus has been reduced in size and weight, the arrangement of built-in speakers has become one of the factors that determine the size of the main body. 12 and 13 are cross-sectional views of a conventional imaging device. A speaker 110 is attached in parallel to an exterior member 112 constituting the housing. A sound emitting hole 116 is opened at a position of the exterior member 112 facing the speaker 110. The substrate 114 is disposed so as to overlap the speaker 110 in the vertical position, and the size of the imaging device in the width direction is determined by the width of the substrate 114 and the thickness of the speaker 110. The speaker 110 is fixed at the illustrated position by a speaker pressing member 118. If the aperture of the speaker 110 is made smaller than the dimension Y shown in FIG. 12, the image pickup apparatus can be made smaller by the dimension X. However, the aperture of the speaker 110 is reduced, and the volume during playback is reduced.

  FIG. 14 is a perspective view of a conventional imaging apparatus including an image display unit that can be opened and closed and rotated. In such an imaging apparatus, in many cases, the image display unit 130 is rotated 90 degrees about the opening / closing axis to be in an open state during reproduction, and a reproduced image is often confirmed. At this time, the sound output hole 132 of the speaker may be provided on the storage surface of the image display unit 130 so that the reproduced sound is generated from the vicinity of the image. However, in this configuration, as shown in FIG. 15, when the image display unit 130 is stored with the image display surface facing outside, the sound emission hole 132 is covered by the image display unit 130, and the reproduced sound is confined. End up.

  Patent Document 1 describes a configuration in which a speaker is attached to an image display unit that can be opened and closed with respect to a housing of an imaging apparatus. FIG. 16 shows a horizontal cross-sectional structure with the image display unit opened.

The image display unit 140 includes a panel housing 142 that houses internal components. The panel casing 142 has a substantially rectangular parallelepiped shape. The liquid crystal panel 146 is disposed on one side surface inside the panel housing 142, that is, the surface facing the camera body 144 when the image display unit 140 is stored in the storage unit. A backlight 148 that illuminates the liquid crystal panel 146 is disposed behind the liquid crystal panel 146 (that is, the back side). A substrate 150 is disposed between the backlight 148 and the other side surface inside the panel housing 142. The size of the substrate 150 is smaller than that of the backlight 148. An empty space 152 is formed in a portion surrounded by the substrate 150, the backlight 148, and the panel housing 142. A speaker 154 is arranged in this empty space 152. Sound from the speaker 154 is output from the other side surface of the panel housing 142.
