WIPO Patent Application WO/2021/012275
Kind Code:
A1
Abstract:
The present application relates to an electronic device. The electronic device comprises a heating member and a loudspeaker assembly. The loudspeaker assembly comprises a housing having an accommodating space and a loudspeaker unit installed in the accommodating space. The loudspeaker unit comprises a vibration system and a magnetic circuit system driving the vibration system. A side of the magnetic circuit system away from the vibration system is at least partially exposed and provided on the housing. The housing is provided with an opening, and the magnetic circuit system is exposed to the housing by means of the opening. The vibration system divides the accommodating space into a front cavity and a rear cavity. The housing is further provided with a sound outlet hole connecting the front cavity to the outside. The electronic device further comprises: a heat conduction member, the heat conduction member comprising a first end part fixed to the side of the magnetic circuit system away from the vibration system, a second end part connected to the heating member, and a connecting part connecting the first end part and the second end part. The heat conduction member is used to guide heat generated by the heating member to the loudspeaker assembly and transmit the heat to the outside of the sound outlet hole along with air in the front cavity. The heat dissipation effect of the electronic device is good.
