Title:
ACOUSTIC OUTPUT DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/213458
Kind Code:
A1
Abstract:
Embodiments of the present application provide an acoustic output device, comprising: a bone conduction acoustic component used for generating a bone conduction sound wave; an air conduction acoustic component used for generating an air conduction sound wave; and a housing used for accommodating at least some elements in the bone conduction acoustic component and the air conduction acoustic component. The housing comprises a first chamber and a second chamber, the first chamber is used for accommodating at least a part of the bone conduction acoustic component, the housing is provided with a sound outlet hole in communication with the second chamber, and the air conduction sound wave is transmitted to the outside of the acoustic output device by means of the sound outlet hole. A frequency response curve of the air conduction sound wave has one or more resonance peaks, and a peak resonance frequency of the resonance peaks is greater than or equal to 1 kHz.
