SPEAKER DEVICE

摘要

A cabinet to which a speaker unit is attached is configured to have an enclosed space where sound waves outputted from the rear surface of the speaker unit are transmitted, a sound guide space separated from the enclosed space, and an outlet for the sound waves transmitted in the sound guide space. A diaphragm is positioned between the enclosed space and the sound guide space of the cabinet, and an actuator is attached to the diaphragm. An audio signal shared with the speaker unit is supplied to the actuator, and diaphragm vibrations are enhanced by the actuator.

1. A speaker device, comprising:
a speaker unit outputting sound waves according to an inputted audio signal; a cabinet to which the speaker unit is attached and which is configured to have an enclosed space where a sound wave outputted from a rear surface of the speaker unit is transmitted, a sound guide space separated from the enclosed space and having the same volume as the enclosed space, and an outlet for the sound wave transmitted through the sound guide space; a diaphragm which is positioned between the enclosed space and the sound guide space in the cabinet, separates the enclosed space and the sound guide space, and is configured with a plate having a comparatively high stiffness; and an actuator to which the audio signal is supplied and which is configured to enhance a vibration state of the diaphragm based on the supplied audio signal.
