Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] One embodiment of this utility model is as follows: Figure 1 and Figure 2As shown, the housing includes a circular mounting groove 1 and a channel groove 2 disposed at the bottom of the mounting groove 1 and communicating with the mounting groove 1. The housing as a whole adopts an IPX7 waterproof design. The speaker assembly includes a magnet assembly 3 snapped into the mounting groove and a cone 4 fixed to the bottom of the magnet assembly 3, as shown. Figure 3 and Figure 4 As shown, the magnet assembly 3 is surrounded by a waterproof sealing ring 11 and is riveted to the side wall of the mounting groove 1 for sealing. The cone 4 is equipped with a self-cleaning component 5 on the side close to the magnet assembly 3, which realizes multiple functions of waterproofing, dustproofing and self-cleaning, extending the service life of the speaker. The cleaning module efficiently removes dust and scale, maintains stable sound quality, and is suitable for harsh environments such as outdoors and bathrooms, expanding the application scenarios.
[0021] The cone 4 includes a bracket 41 connected to the magnet assembly 3 and a diaphragm 42 disposed inside the bracket 41. The back of the cone 4 is provided with damping adhesive and fixed to the magnet assembly 3. The diaphragm 42 is made of woven glass fiber and the surface of the diaphragm 42 is coated with a hydrophobic coating to prevent water droplets from adhering.
[0022] The self-cleaning component 5 is installed on the side of the bracket 41 near the diaphragm 42. The self-cleaning component 5 is driven by a miniature piezoelectric ceramic sheet fixed on the bracket 41. It has low power consumption and does not affect the normal operation of the speaker. An ultrasonic generator is installed at the output end of the piezoelectric ceramic sheet, which periodically generates high-frequency vibrations to remove dust and scale. The structure of the piezoelectric ceramic sheet is a prior art that has been disclosed. It is not a technical solution protected by this application. The specific structure will not be described again.
[0023] A humidity sensor 6 and a dust sensor 7, which are electrically connected to the self-cleaning component 5, are installed inside the housing around the piezoelectric ceramic sheet. The self-cleaning component 5 is equipped with a remote communication module that supports remote control of the cleaning cycle and intensity via a mobile APP. The cleaning function is automatically triggered when the humidity or dust reaches the threshold.
[0024] The neck section of the sound channel slot 2 is equipped with a removable dustproof screen 8 for easy cleaning and replacement. The surface of the dustproof screen 8 is coated with an antibacterial coating to inhibit bacterial growth.
[0025] The magnet assembly 3 has a terminal block 12 on its top and a stud structure 13 on its central axis to fix the speaker. It can be installed directly or by installing an auxiliary mounting bracket on the stud structure.
[0026] In summary, the speaker housing of this application adopts an IPX7 waterproof structure. The 360° waterproof riveting edge compresses the sealing ring during the riveting process to achieve a sealing and waterproof effect. A dustproof mesh is set in the channel groove. When the humidity sensor and dust sensor detect the corresponding humidity and the dust content exceeds the threshold, the self-cleaning component is powered on and generates high-frequency vibration to remove dust and scale from the surface of the diaphragm, thus achieving multiple functions of waterproofing, dustproofing and self-cleaning.
