Abstract

A speaker has a substantially reduced overall size while producing a complete low frequency sound range at high output amplitude. The speaker includes a main body having open sections at both ends thereof. A sounding body pinched by ringed first dampers is secured to each of the open sections of the main body so that the inside of the main body is kept air-tight. A first opening is provided at the middle part of the side of the main body. Lid members are secured on the outside of the two sounding bodies via a ringed second damper so as to keep the inside of the lid member air-tight. A second opening is created around the middle of the bottom of each of the lid members. A disc-like membrane is secured to the second dampers such that the lid members cover the membranes and cover the open section of the main body to keep the inside of the lid members air-tight.
