Description

Loudspeaker assembly Technical Field The present disclosure relates to a speaker assembly. Background In the speaker apparatus which is common at present, an electroacoustic assembly and a housing accommodating the electroacoustic assembly are included. During operation of the speaker device, heat generated by operation of the electroacoustic assembly must be effectively conducted out of the housing and released into the environment, which may otherwise cause overheating of the battery due to heat accumulation, thereby causing the speaker device to stop operation and even be damaged. For this reason, heat is conducted from the electroacoustic assembly to the environment. However, in the prior art designs, devices for dissipating heat are often lacking. As the demands on the functionality of speaker devices continue to increase, more and more power is required, which exacerbates the heat dissipation requirements for speaker devices.
