Abstract
The present disclosure relates to the technical field of electro-acoustic products. Disclosed is a speaker module installed in an electronic terminal, comprising: a housing receiving therein a speaker unit which is electrically connected with an external circuit of the module via an FPCB; and a sensor configured to detect ambient noise, the sensor being electrically connected with the FPCB, the sensor being installed at a position adjacent to a sound exit hole of the electronic terminal, and the sensor being used to transmit a detected ambient noise signal to a CPU of the electronic terminal via the FPCB. The electronic terminal installed with the speaker module may automatically tune the sound volume of the speaker module according to the amount of noise in the external environment, thereby ensuring a user to timely hear a prompt tone generated by the electronic terminal in any environment, and effectively avoiding missing an important event or call due to failure to hear the prompt tone.
