Abstract
An electroacoustic module includes an installation member, first and second sounding devices. The installation member includes first and second installation cavities, first and second sound outlets, and a sound guide channel. The first sounding device in the first installation cavity divides the first installation cavity into a first front cavity connected to the first sound outlet and a first rear cavity. The second sounding device in the second installation cavity divides the second installation cavity into a second front cavity connected to the second sound outlet and a second rear cavity which is a closed cavity and which is connected to the first rear cavity through the sound guide channel. A phase of a first sound wave emitted by the first sounding device through the first sound outlet is different from a phase of a second sound wave emitted by the first sounding device through the second sound outlet.
