Abstract
A loudspeaker holder including a baffle plate and a loudspeaker supported by the baffle plate is rotatably coupled to a portable sound reproducing device having an operating surface and an audio-amplifier for supplying a power output signal to the loudspeaker through a pin and opening coupling means. To utilize the loudspeaker, the loudspeaker holder is rotated about the pin to form a space between the baffle plate and the operating surface. The sounds generated by the loudspeaker are transmitted to the outside through the space and an opening provided in the baffle plate. In case of carrying the portable sound reproducing device, loudspeaker holder is rotated about the pin to bring the baffle plate into contact with the operating surface, and to extinguish the space.
