The second functional module is disposed in the accommodation space, and the second functional module includes an acoustic device 300, which may include at least one of a microphone, a receiver, and a speaker. There is an assembling gap 101 between the first housing 100 and the first functional module 900. One port of the assembling gap 101 is exposed on the outer surface of the electronic device. The assembling gap 101 can be used to conduct sound of the electronic device. A sound guide channel 200 is provided inside, and the acoustic device 300 communicates with the assembly gap 101 through the sound guide channel 200.

In a specific operation process, when the user makes a sound, the sound enters the housing through the assembly gap 101, and the assembly gap 101 is transmitted to the acoustic device 300 through the sound guide channel 200. When the acoustic device 300 emits sound, the sound is transmitted to the assembly gap 101 through the sound guide channel 200, and then transmitted to the user through the assembly gap 101. Optionally, the first functional module 900 may include a display module 920, and the first housing 100 may be a middle frame or a back cover of an electronic device. When the first housing 100 is a middle frame, the middle frame and the display The modules 920 are connected, and there is an assembly gap 101 between the middle frame and the display module 920.

Wherein, the back cover can be a battery cover of an electronic device.

In the embodiment of the present invention, the first housing 100 and the first functional module 900 have an assembly gap 101 after being assembled. Therefore, the assembly gap 101 between the first housing 100 and the first functional module 900 can be used to transmit sound information. As a result, there is no need to provide sound guide holes on the housing, thereby reducing the number of openings of the housing, thereby improving the integrity and appearance consistency of the housing, so that the appearance and texture of the housing are better, and the user experience is improved. At the same time, the assembly gap 101 is narrower than the sound guide hole, which can effectively relieve the water vapor and dust in the environment from entering the housing, thereby improving the waterproof performance and dustproof performance of the electronic device.

In addition, the assembly gap 101 between the first housing 100 and the first functional module 900 is used to transmit sound information, and there is no need to additionally process sound guide holes on the first housing 100 or the functional module, thereby optimizing the first housing 100 With the processing technology of the first functional module 900, the processing steps of the first housing 100 and the first functional module 900 are simplified, thereby reducing the manufacturing cost of the electronic device.
