| description | This application provides a speaker module and an electronic device. The speaker module includes a housing and a speaker. The housing has mounting space, the speaker divides the mounting space into first space and second space, and when the speaker works, a first sound wave is formed in the first space, and a second sound wave is formed in the second space, where the second sound wave and the first sound wave have equal amplitudes and opposite phases. The housing further has a first sound emitting hole and a second sound emitting hole that are disposed opposite to each other, the first sound emitting hole communicates with the first space, and the second sound emitting hole communicates with the second space. The housing further has a third sound emitting hole and an inverter cavity, one end of the inverter cavity communicates with the second space, the other end of the inverter cavity communicates with the third sound emitting hole, the inverter cavity is configured to form a third sound wave at the third sound emitting hole when the speaker works, a phase of the third sound wave is the same as a phase of the first sound wave, and the third sound wave is superposed with the first sound wave passing through the first sound emitting hole. The speaker module has high loudness and can effectively suppress a sound leakage. |
