Abstract

A loudspeaker is disclosed having a back plate, a driver attached to the back plate, the driver being responsive to an electrical signal, an enhancer having a neck and a mouth, the neck attached to the driver and movable in accordance with the movement of the driver, a thin film membrane defining a hole, the membrane attached to the enhancer such that the hole corresponds in size and location with the mouth of the enhancer, a frame for supporting the membrane and maintaining it in a taut state, a rubber type adhesive for dampening the membrane resonances and for adhering the membrane to the frame, and a clamp ring for clamping the membrane to the frame. Clarity of sound can be further improved by including a plurality of sound breathers in the back plate of the speaker. For improved sound radiation capability, especially in the middle and high frequency sound ranges, the size and the shape of the enhancer can be modified in various ways, including a frustoconical, parabolic, or bell-shaped enhancer.
