Abstract:
Provided in an embodiment of the present invention are a sound emission device and an electronic apparatus. The sound emission device comprises a vibration system, a magnetic circuit system, a housing and an antenna. The housing comprises an installation portion having at least one open end, and a rear cavity portion correspondingly arranged at an outer side of a first sidewall of the installation portion for formation of a rear cavity. The magnetic circuit system and the vibration system are fixed inside the installation portion. The first sidewall is provided with a rear sound hole arranged at a position facing the rear cavity and used to communicate a magnetic gap in the magnetic circuit system and the rear cavity. The antenna is provided at the sound emission device. The embodiment of the present invention enables a sound emission device to have a reduced size while achieving favorable acoustic performance. Moreover, an antenna can be integrated into the compact sound emission device to increase the level of integration.
