After rotating in the direction, the upper end portion of the operation panel portion is moved vertically upward while being housed in the audio device main body, and further, Serial acoustic device according to claim 8, wherein moving the lower end portion of the operation panel in the horizontal direction. 10. An operation panel portion which can be opened and closed with respect to the audio device main body, two speaker housing portions which are inclined outward toward the upper right and left sides of the audio device main body, respectively, and a motor as a power source. A mechanism section for opening and closing the operation panel section and for horizontally inserting and removing each of the two speaker housing sections with respect to a diagonally forward front of the front surface of the audio device main body in accordance with opening and closing of the operation panel section; An audio device comprising: a control unit for controlling; and at least one speaker provided in each of the two speaker housings and supplied with an audio signal from an audio output circuit in the audio device body. 11. A loudspeaker provided inside each of the two loudspeaker accommodating portions is disposed horizontally toward the center of the audio device main body, and the control portion controls the mechanism portion when the operation panel portion is opened. Then, the upper end portion of the operation panel portion is moved downward in the vertical direction to a position where a space where each of the two speaker housing portions can be sent forward from the front surface of the audio device main body, and the lower end portion is moved forward in the horizontal direction. When the space that can send out the speaker accommodating portion forward from the front of the audio device main body can be secured, each of the two speaker accommodating portions is simultaneously sent out obliquely forward of the front of the audio device main body,
By controlling the mechanism section, each of the two speaker housing sections is simultaneously rotated in the vertical direction to turn each speaker forward, and when the operation panel section is closed, each of the two speaker housing sections is moved in the horizontal direction. Then, the upper part of the operation panel is moved vertically upward while being housed in the audio device main body, and the lower part of the operation panel is moved horizontally. Claim 1

A speaker accommodating portion that can be put in and out of the front of the audio device main body, a mechanism that simultaneously moves each of the two speaker accommodating units out of the audio device main body by using a motor as a power source, and controls the mechanism. Then, each of the two speaker accommodating portions is sent forward from the front of the audio device main body, and each of the two speaker accommodating portions is sent forward from the front of the audio device main body. A control unit for turning the speaker of the camera forward,
An audio device, comprising: at least one speaker provided in each of the two speaker housings and supplied with an audio signal from an audio output circuit in the audio device main body. 13. An operation panel section which can be put in and out of the audio apparatus main body, a speaker housing section which is arranged on both left and right sides of the operation panel section and which can be put in and out of the side of the operation panel section respectively, and a motor as a power source. A mechanism section for simultaneously inserting and removing each of the two speaker housing sections from the inside of the audio apparatus main body;
A control unit for simultaneously sending each of the two speaker housing units forward from the side surface of the audio device main body, and at least one audio signal supplied from an audio output circuit provided in each of the two speaker housing units in the audio device main body. An acoustic device comprising: two speakers. 14. The acoustic device according to claim 1, wherein the speaker is used as a center speaker. 15. The audio device according to claim 1, wherein the audio device main body is an in-vehicle audio device.
