Description

Technical Field

[0001] The utility model belongs to the technical field of dustproof net installation, and in particular relates to a dustproof net for a loudspeaker. Background Art

[0002] A speaker is a device that plays audio. To prevent dust from entering the speaker and interfering with the components inside the speaker, a dust net is usually installed on the surface.

[0003] The Chinese utility model patent with the announcement number CN209283489U discloses a speaker dust screen that is easy to fix, and proposes;

[0004] 1. The dust screen of existing speakers is generally fixed directly on the surface of the speaker, which has a dust-proof effect. However, after long-term use, a lot of dust accumulates on the surface of the dust screen, which is not convenient to clean, resulting in poor sound amplification effect;

[0005] 2. The surface of the existing speaker dust screen is generally set to an arc-shaped structure. The mesh structure on the surface of the dust screen makes it easy to deform. The deformed dust screen is not only unsightly but also easily causes dust accumulation at the wrinkles, resulting in poor dustproof effect.

[0006] To address the above problems, we propose another solution. Utility Model Content

[0007] The purpose of the utility model is to provide a dustproof net for a loudspeaker, so as to solve the problems existing in the background technology.

[0008] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0009] A dustproof net for a speaker, comprising a speaker body, the speaker body is used to play audio, a sound hole is opened at the front end of the speaker body, the sound hole can transmit sound to the outside and serves as a connecting part for installing the dustproof component, and a dustproof component is arranged inside the sound hole;

[0010] The dustproof component includes a mounting ring, which is slidably arranged inside the sound hole, and a dustproof net is installed inside the mounting ring. The mounting ring is used for installing the dustproof net, and the dustproof net can reduce the entry of external dust into the speaker and interfere with the electronic components inside it. The speaker body is provided with a slot positioned on both sides of the sound hole, and both sides of the mounting ring are fixedly connected with elastic blocks matching the slots, and a limiting hole is provided at the bottom of the slot, and a limiting column matching the limiting hole is provided on the outside of the elastic card block. The user presses the elastic card block to make the elastic card block elastically deform, so that the dustproof component can be placed into the sound hole through the slot, and then when the limiting column enters the limiting hole, the installation of the dustproof component is completed.

[0011] A support member located at the front end of the dustproof net is rotatably mounted inside the mounting ring, a scraper is arranged at the rear end of the support member, and the scraper abuts against the dustproof net, and an inclined dust falling groove is opened at the lower end of the mounting ring.

[0012] The front end of the elastic block is provided with anti-slip grooves.

[0013] A side groove is provided on the side of the dustproof net, and a buckle matching the side groove is fixed on the rear end of the mounting ring.

[0014] In the utility model, by providing the elastic card block and utilizing the elastic card block to restore elastic deformation, the limiting column is pressed into the limiting hole, so that the dustproof component can be quickly installed on the speaker. By providing the support member at the front end, the dustproof net can be prevented from contacting the outside world and deformation of the dustproof net due to external force can be prevented from occurring at the source. In addition, when the user rotates the support member, the scraper can scrape off the dust accumulated on the dustproof net. Compared with the prior art, the structure is simpler and the operation is more convenient. The dustproof net can also be preliminarily cleaned to avoid frequent cleaning or replacement of the dustproof net. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0021] Example:

[0022] like Figure 1-Figure 2 As shown, a dustproof net for a speaker includes a speaker body 100, a sound hole 101 is opened at the front end of the speaker body 100, and a dustproof component is arranged inside the sound hole 101;

[0023] The dustproof component includes a mounting ring 102, which is slidably arranged inside the sound hole 101, and a dustproof net 103 is installed inside the mounting ring 102. The speaker body 100 is provided with slots 104 located on both sides of the sound hole 101, and both sides of the mounting ring 102 are fixedly connected with elastic blocks 105 matching the slots 104. A limiting hole 106 is provided at the bottom of the slot 104, and a limiting column 107 matching the limiting hole 106 is provided on the outside of the elastic block 105.

[0024] The speaker body 100 is used to play audio, the sound hole 101 can transmit sound to the outside world and serve as a connecting part for installing a dustproof component. The mounting ring 102 is used to install a dustproof net 103. The dustproof net 103 can reduce the entry of external dust into the speaker and interfere with the electronic components inside it. The user presses the elastic card block 105 to cause the elastic card block 105 to undergo elastic deformation, so that the dustproof component can be placed into the sound hole 101 through the card slot 104, and then when the limiting column 107 enters the limiting hole 106, the installation of the dustproof component is completed.

[0025] A support member 200 located at the front end of the dustproof net 103 is rotatably installed inside the mounting ring 102 , a scraper 201 is provided at the rear end of the support member 200 , and the scraper 201 abuts against the dustproof net 103 , and an inclined dust drop groove 202 is opened at the lower end of the mounting ring 102 .

[0026] The support member 200 can not only press the elastic block 105 to prevent the mounting ring 102 from being deformed by excessive pressure, but also protect the dust screen 103. The scraper 201 can scrape off the dust accumulated on the dust screen 103 and discharge it from the dust collection groove 202 when the user rotates the support member 200.

[0027] The front end of the elastic block 105 is provided with an anti-slip groove 300, which can increase the friction between the finger and the elastic block 105 when the dustproof component is removed, and facilitate pushing the elastic block 105 closer to the axis.

[0028] A side groove 400 is provided on the side of the dustproof net 103 , and a buckle 401 matching the side groove 400 is fixed to the rear end of the mounting ring 102 . The side groove 400 cooperates with the buckle 401 , so that the dustproof net 103 can be quickly replaced.

[0029] The working principle of this embodiment: when installing the dustproof component, the user only needs to press the elastic card block 105 to make the elastic card block 105 elastically deform, and then put the dustproof component into the sound hole 101 through the card slot 104, and then release the elastic card block 105. The limiting column 107 enters the limiting hole 106 due to the elastic deformation restored by the elastic card block 105, and the installation of the dustproof component is completed. The dustproof component can be removed by reversing the above operation.

[0030] In this embodiment, by providing an elastic block 105 and utilizing the elastic block 105 to restore elastic deformation, the limiting column 107 is pressed into the limiting hole 106, so that the dustproof component can be quickly installed on the speaker. By providing a scraper 201, when the user rotates the support member 200, the dust accumulated on the dustproof net 103 can be scraped off, thereby avoiding frequent cleaning or replacement of the dustproof net 103.

[0031] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
