Title:

SOUND PRODUCING DEVICE

Document Type and Number:

WIPO Patent Application WO/2019/101161

Kind Code:

A1

Abstract:

Disclosed in the present invention is a sound producing device, comprising a housing having a hollow cavity; a first sound producing membrane mounted on the housing and separating the hollow cavity as a first cavity and a second cavity; a main vibration component mounted in the second cavity and separating the second cavity as a main sound producing cavity and a mounting cavity; a first sound outlet hole and a second sound outlet hole respectively provided on wall surfaces of the housing corresponding to the main sound producing cavity and the first cavity; and a driving mechanism provided in the second cavity. The driving mechanism drives the main vibration component to vibrate; the vibration drives, by means of air in the main sound producing cavity, the first sound producing membrane to vibrate; sounds produced by the main vibration component and the first sound producing membrane are converged together; the vibration of the first sound producing membrane lags behind that of the main vibration component to some degree, so that a reverb effect is yielded by the sound produced by the first sound producing membrane and the sound produced by the main vibration component. Therefore, the low-frequency characteristics of the sound producing device and the fullness and depth of the sound are improved.
