Abstract:
A loudspeaker (100) and an electronic device. The loudspeaker (100) comprises a guide structure (130), a beam generation module (140), a valve (120), and a housing (110), wherein the valve (120) is provided with a passageway (121), the valve (120) and the housing (110) enclose a chamber (150) for accommodating the beam generation module (140), and the valve (120) is configured to modulate a first beam generated by the beam generation module (140). By means of providing the guide structure (130), the sound pressure of a second beam generated by means of the first beam modulated by the valve (120) is higher. The loudspeaker (100) has a high energy conversion efficiency and a high sound pressure transmittance, and the loudspeaker (100) and the electronic device, which comprises the loudspeaker (100), have a good performance capability with regard to low-frequency audible sound.
