Abstract
Provided are a speaker and an electronic device. The speaker includes: a speaker case; a speaker body arranged in the speaker case and configured to vibrate and produce sound, the speaker body dividing the speaker case into a front sound cavity and a rear sound cavity, the speaker case being provided with a speaker hole, and the front sound cavity communicating with outside of the speaker case through the speaker hole; and a resonator arranged at the speaker case, a side of the resonator being arranged corresponding to the front sound cavity, and another side of the resonator being exposed to outside of the speaker case. By coupling the resonator in the front sound cavity of the speaker, the high frequency reproduction of the speaker is improved and the intermodulation distortion of the speaker is reduced, thereby improving the sound quality of the speaker in the electronic device.
