Document Type and Number:
WIPO Patent Application WO/2018/121651
Kind Code:
A1
Abstract:
The present application relates to the field of acoustic device technologies, and in particular, to an acoustic device and a piece of electronic equipment. The acoustic device comprises: an upper shell, a lower shell, an acoustic assembly, an acoustic tube and a strain relief tube. The acoustic assembly is accommodated within an accommodation space between the lower shell and the upper shell. The acoustic tube is provided on one side of the lower shell, and the strain relief tube is provided on the other side of the lower shell. The acoustic device further comprises a seal assembly, one side of the seal assembly being connected to the bottom surface of the lower shell. The acoustic assembly comprises a diaphragm frame, one side of the diaphragm frame being connected to the other side of the seal assembly, and the strain relief tube accommodates the other side of the diaphragm frame. By means of the connection fittings between the seal assembly, the diaphragm frame and the strain relief tube, the accommodation space is divided into a first accommodation cavity and a second accommodation cavity, and the first accommodation cavity and the second accommodation cavity are both in a sealed state, whereby corresponding acoustic assemblies respectively accommodated within the first accommodation cavity and the second accommodation cavity do not influence each other, so that the acoustic device can transmit sound signals with good quality.
