Title: SPEAKER AND VIBRATION-DAMPING STRUCTURE FOR SPEAKER
Abstract:
The invention relates to a speaker. Disclosed are a speaker and a vibration-damping structure for a speaker. The vibration-damping structure for a speaker comprises: a first elastic member for connecting to a speaker body; and a second elastic member for connecting to a speaker fixing structure. The first elastic member and the second elastic member are connected by means of a cantilever arm. The cantilever arm is made of an elastic material. In the invention, the cantilever arm connects the speaker body with the speaker fixing structure to form a non-coaxial connection structure, so that force generated from vibration of the speaker body is not directly transferred to the speaker fixing structure. Rather, the force is absorbed, filtered and diminished by the cantilever arm before acting upon the speaker fixing structure, thereby significantly damping vibration caused by a large amplitude of a speaker.
