Abstract
Provided is a loudspeaker applied to an electronic device, including: a speaker body configured for vibrating and producing sound; a first acoustic channel having a first end communicated with the speaker body and a second end forming a first sound output port on a case of the electronic device; and a second acoustic channel having a first end communicated with the speaker body and a second end forming a second sound output port on the case of the electronic device. The first and second sound output ports are located on adjacent wall surfaces of the case of the electronic device. Compared with the related art, larger port area can be achieved by separately forming sound output ports on adjacent walls of the housing, resulting in high frequency response and higher gain. The horn-shaped sound output port facilitates design and reduces flow-related distortion and noise at low frequencies.
