Title:
SPEAKER DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/012181
Kind Code:
A1
Abstract:
The present invention, with structural simplification secured, heightens the accuracy of oscillator position relative to an actuator and improves sound quality. The present invention is provided with an actuator operated in accordance with a drive signal, a spring holder elastically deformable at least in part and having a joint to which the actuator is joined, and a plurality of oscillators interconnected via the spring holder and oscillated in accordance with the motion of the actuator. Thus, because the plurality of oscillators are interconnected via the spring holder and the actuator is joined to the joint of the spring holder, the interconnection of the plurality of oscillators and the joining of the actuator are both achieved by the spring holder, and the accuracy of oscillator position relative to the actuator is heightened, making it possible, with structural simplification secured, to heighten the accuracy of oscillator position relative to an actuator and improve sound quality.
