When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

In the related art, an electronic device such as a mobile phone generally includes an audio playing device, and a sound outlet is correspondingly disposed on the electronic device. However, due to the environment and the time of use of the electronic device, the problems of soundless, low sound, and vibration noise of the audio playback apparatus often occur, most of which are caused by the foreign objects adhering to the dust-proof member fitted to the sound output hole. And the foreign matter attached to the dust-proof member generally contains grease, cosmetics, dust mixture, and the like accumulated due to direct contact of the user with the electronic equipment for a long time, and thus is difficult to remove.

FIG. 1 is a schematic diagram of a partial cross-sectional structure of an electronic device in an exemplary embodiment of the disclosure; fig. 2 is a schematic front structure diagram of an electronic device in an exemplary embodiment of the present disclosure. As shown in fig. 1 and 2, the electronic device 1 includes: a device body 11, an audio playing device 12 and a control chip 13. The device body 11 is provided with a sound outlet hole 111. The audio playing device 12 includes a dust-proof member 121, a heat conducting component 122, a magnetic steel 123 and a coil 124. Dustproof member 121 and play sound hole 111 equipment cooperation, heat conduction component 122 respectively with magnet steel 123 and dustproof member 121 heat conduction cooperation, magnet steel 123 and coil 124 heat conduction are connected. The control chip 13 is electrically connected to the audio playing device 12, so that the audio playing device 12 receives the first sound source signal and plays the coil heating sound source corresponding to the first sound source signal.

Set up heat-conducting component 122 through audio playback device 12 for electronic equipment 1 to make heat-conducting component 122 be connected with dust keeper 121 and magnet steel 123 heat conduction respectively, make when control chip 13 control audio playback device 12 broadcast coil and make the heat sound source, the heat of coil 124 can be followed heat-conducting component 122 and transferred to dust keeper 121 on, thereby impel that the greasy dirt or other impurity that block up dust keeper 121 can melt or volatilize. Above-mentioned structure sets up makes dust piece 121 can realize automatic mediation, avoids dust piece 121 to block up noiselessness, the sound is little, the noise problem that leads to, has promoted audio playback device 12 and electronic equipment 1's broadcast performance and user and has used experience.

Taking the electronic device 1 as a mobile phone as an example, a user may send a control instruction to the control chip 13 through a software platform at a mobile phone end, so that the audio playing apparatus 12 plays a sound source signal that causes the coil 124 to generate heat. For example, a plurality of coil heating sound sources with heating effects from low to high may be built in the software platform, and after the user selects a play instruction corresponding to the "first sound source signal", the control chip 13 receives the instruction and controls the audio playing device 12 to operate. In the process of playing the first sound source signal by the audio playing device 12, the coil 124 therein generates corresponding heat due to working, the heat is transferred from the coil 124, the magnetic steel 123 and the heat conducting component 122 to the dust-proof part 121, and the dust-proof part 121 realizes self dredging and purification by means of the heat, so that the dredging intelligence of the dust-proof part 121 and the operation convenience of a user are improved.

The monitoring process can also be completed by a software platform, and the real-time temperature of the coil 124 can be acquired by the temperature monitoring part, transmitted to the control chip 13 and displayed by the software platform. Taking the maximum heating temperature that the coil 124 can bear as 110 degrees as an example, when the temperature of the coil 124 displayed by the software platform is 60 degrees, the audio source with higher heating effect can be played instead to raise the temperature of the coil 124, and when the temperature of the coil 124 displayed by the software platform is close to 110 degrees, the audio source can be stopped to control the temperature of the coil 124. Alternatively, a foreign substance removal mode may be pre-configured in software, in which the software defines the temperature range of the coil 124, the heating is continued when the temperature of the coil 124 is insufficient, and the heating is stopped when the temperature of the coil 124 approaches the maximum temperature that the coil can withstand, and in which the electronic device 1 can automatically complete the removal of the foreign substance on the dust-proof member 121.
