The present invention relates to the technical field of electro-acoustic products. Disclosed is a speaker module installed in an electronic terminal and comprising a housing and a sensor (50) for detecting external noise; a speaker monomer (30) is received in the housing; the speaker monomer (30) is electrically connected to the external circuit of the module via an FPCB (40); the sensor (50) is electrically connected to the FPCB (40); the installation position of the sensor (50) is adjacent to the sound cavity of the electronic terminal, and the sensor (50) is used to transmit a detected external noise signal to the CPU of the electronic terminal via the FPCB (40). The electronic terminal having the speaker module installed automatically adjusts the sound volume of the speaker module according to the amount of noise in the external environment, thus ensuring a user to timely hear a prompt tone generated by the electronic terminal in any environment, effectively avoiding missing an important event or call due to not hearing the prompt tone. |
