Abstract

This application provides an acoustic output device, comprising: a bone conduction acoustic component for generating bone conduction sound waves; an air conduction acoustic component for generating air conduction sound waves; and a housing for accommodating at least a portion of the bone conduction acoustic component and the air conduction acoustic component. The housing includes a first chamber and a second chamber, the first chamber accommodating at least a portion of the bone conduction acoustic component, and the housing having a sound outlet communicating with the second chamber. The air conduction sound waves are transmitted to the outside of the acoustic output device through the sound outlet. The frequency response curve of the air conduction sound waves has one or more resonant peaks, and the peak resonant frequency of the resonant peaks is greater than or equal to 1 kHz.
