[0041] In addition, although the terms used in the present application are selected from well-known and commonly used terms, some of the terms mentioned in the specification of the present application may be selected by the applicant according to his or her judgment, and their detailed meanings are described in the relevant parts of the description herein.

[0042] In addition, it is required to understand the present application not only through the actual terms used, but also through the meanings implied by each term.

[0043] The technical solutions provided by each embodiment of the present application will be described in detail below in conjunction with the drawings.

[0044] The embodiment of the present application provides an electronic device. Referring to Figures 1 to 8 , the electronic device 1 provided by the embodiment of the present application includes: a cover assembly 10, a frame 20, an acoustic component 30 and a sealing ring 40.

[0045] For the convenience of those skilled in the art to understand, taking the electronic device 1 as a mobile phone as an example, the cover assembly 10 may include a battery back cover and a camera decorative ring provided on the battery back cover, etc. The frame 20 may be a middle frame of the mobile phone. For example, the middle frame of the mobile phone includes a group board support part and a border part. Exemplarily, the cover assembly 10 may also be an integrated back cover. In addition, exemplarily, the acoustic element 30 may be an acoustic element such as a microphone or a speaker. It should be noted that the solution provided in the embodiments of the present application can also be applied to other devices except mobile phones, and will not be elaborated here.

[0046] In the embodiments of the present application, the cover assembly 10 is provided with a first sound guiding hole 10a, a first sound guiding channel 10b and a first docking part 10c that are sequentially communicated. Exemplarily, the first sound guiding hole 10a penetrates the outer surface of the cover assembly 10, so as to facilitate the acoustic element 30 to acquire the sound outside the electronic device 1 through the first sound guiding hole 10a, or to facilitate the sound emitted by the acoustic element 30 to be transmitted out through the first sound guiding hole 10a.

[0047] The frame 20 is provided with a second sound guiding channel 20a and a second docking part 20b. The sound transmission port 31 of the acoustic element 30 is communicated with the second docking part 20b through the second sound guiding channel 20a. Exemplarily, when the acoustic element 30 is a microphone, the sound transmission port 31 may be the sound inlet of the microphone. When the acoustic element 30 is a speaker, the sound transmission port 31 may be the sound outlet of the speaker.

[0048] The second docking part 20b and the first docking part 10c are sleeved with each other. For example, the first docking part 10c is sleeved inside the second docking part 20b, or the first docking part 10c is sleeved outside the second docking part 20b. The sealing ring 40 is sleeved between the first docking part 10c and the second docking part 20b, and seals the gap between the second docking part 20b and the first docking part 10c, so that the first sound guiding channel 10b and the second sound guiding channel 20a are hermetically docked. In this way, when the acoustic element 30 is a microphone, the sound in the environment can be transmitted to the sound inlet of the microphone through the sound channel between the first sound guiding hole 10a and the second sound guiding channel 20a, and thus be received by the microphone. When the acoustic element 30 is a speaker, the sound emitted by the speaker can be transmitted outside the electronic device 1 through the sound channel between the second sound guiding channel 20a and the first sound guiding hole 10a.

[0049] In this way, in the embodiments of the present application, the first sound guiding hole 10a, the first sound guiding channel 10b, and the first docking portion 10c are sequentially communicated, and the sound transmission port 31 of the acoustic element 30 is communicated with the second docking portion 20b through the second sound guiding channel 20a. When the cover assembly 10 covers the frame 20, the second docking portion 20b and the first docking portion 10c are sleeved with each other. For example, the first docking portion 10c is sleeved inside the second docking portion 20b, or the first docking portion 10c is sleeved outside the second docking portion 20b.

[0050] Further, the sealing ring 40 is sleeved between the first docking portion 10c and the second docking portion 20b. The sealing ring 40 can also preferably seal the gap between the second docking portion 20b and the first docking portion 10c, thereby avoiding sound leakage at the gap between the first docking portion 10c and the second docking portion 20b. Exemplarily, when the acoustic element 30 is a microphone, since there is no sound leakage at the gap between the first docking portion 10c and the second docking portion 20b, during the operation of the electronic device 1, the generated noise is not easily received by the microphone, thus improving the sound collection effect of the microphone.

[0051] Furthermore, it can be concluded that by adopting the solution provided in the embodiments of the present application, it is not necessary to provide foam at the end faces of the two sound guiding channels. Therefore, the situation where the foam lifts the cover assembly can be avoided. Moreover, the sealing ring 40 is sleeved between the first docking portion 10c and the second docking portion 20b, and the sealing ring 40 can seal the gap between the second docking portion 20b and the first docking portion 10c. Thus, on the premise of ensuring that the cover assembly is not lifted and deformed, sound leakage at the sound channel between the sound transmission port 31 of the acoustic element 30 and the first sound guiding hole 10a can be prevented.
