Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, and more specifically, to a loudspeaker with a quick-release filter structure. Background Technology

[0002] A loudspeaker is a device used to amplify sound and increase its propagation distance. It can convert weak sound signals into clearly audible sound waves. Loudspeakers are used in various fields such as education, emergency response, and entertainment through acoustic structures or electronic amplification technology. Some high-power loudspeakers or amplifiers are equipped with fans due to heat dissipation requirements and require the installation of dust filters to prevent dust from clogging the air intake. For example, application number CN202321440291.7 discloses a loudspeaker with a dustproof function. Through the setting of matching columns and fixing cylinders, the dustproof frame can be quickly and conveniently installed on the surface of the loudspeaker cover. At the same time, the use of locking blocks and locking blocks allows the dustproof frame to be locked and fixed by the fixing blocks and locking blocks during installation, making the overall installation more stable and firm. It also facilitates the installation and disassembly of the dustproof frame and provides convenience when cleaning is required. The dustproof filtration function used in loudspeakers in the prior art has the problems of complex maintenance and risk of sealing failure. The fine filter has strict requirements for pre-filtration, which must ensure that the particle size of the incoming particles is smaller than the diameter of the membrane tube. Otherwise, it is easy to clog and obstruct airflow. Moreover, if a single fiber is damaged, the entire membrane module must be replaced, which is costly and cumbersome. Furthermore, the peripheral seal of the filter and the fit between the inlet and outlet holes and the support structure are prone to leakage. After disassembly and reassembly, it is difficult to reset, which affects the filtration efficiency. Therefore, a loudspeaker with a quick-release filter structure is proposed to address the above problems. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a loudspeaker with a quick-release filter structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a loudspeaker with a quick-release filter structure, comprising a loudspeaker body and a quick-release filter assembly. The quick-release filter assembly is provided on the side end face of the loudspeaker body. The quick-release filter assembly includes a limiting groove and an annular electromagnet. The limiting groove is carved into the side end face of the loudspeaker body. An annular electromagnet is fitted and installed at the edge of the limiting groove. A fastening groove is provided at the edge of the limiting groove. A filter plate is fitted and connected to the limiting groove. The filter plate includes a frame and an outer layer.

[0008] Preferably, the fine filtration layer consists of a support rod and a HEPA filter, wherein the support rod is fixedly connected to the inner diameter surface of the frame, and the outer surface of the support rod is bonded with a HEPA filter, and the HEPA filter is circular.

[0009] Preferably, the outer surface of the funnel-shaped flow guide is provided with a number of through holes, and the through holes are honeycomb-shaped, and the surface of the funnel-shaped flow guide is provided with a number of grooves.

[0010] Preferably, an annular groove is provided on the outer surface of the frame, and eight sets of neodymium iron boron magnets are provided on the inner side of the annular groove, and a sealing ring is provided on the outer surface of the frame.

A switch button is provided on the side of the handle away from the control button, and a wiring hole is provided on the side of the switch button.

[0012] The technical effects and advantages of this utility model are as follows: Compared with existing technologies, this loudspeaker with a quick-release filter structure is used in which the sound emitted by the loudspeaker body is transmitted through the quick-release filter assembly. The device utilizes an outer layer, middle layer, inner layer, and fine filter layer to prevent impurities and moisture from entering the inner cavity of the loudspeaker body. Magnetic adsorption facilitates the connection between the filter plate and the locking groove, enabling quick disassembly. This solves the problems of existing loudspeaker dust filtration systems, which suffer from complex maintenance and the risk of seal failure. The fine filter requires stringent pre-filtration, ensuring that the particle size is smaller than the membrane tube diameter; otherwise, blockage can obstruct airflow. Furthermore, damage to a single fiber necessitates replacement of the entire membrane assembly, resulting in high costs and cumbersome operation. Additionally, leaks are prone to occur at the perimeter seals of the filter and at the inlet / outlet holes, making reassembly difficult and affecting filtration efficiency.

[0013] Compared with the prior art, this megaphone with a quick-release filter structure is used in a way where electronic components are installed inside the megaphone body, and the megaphone body is powered by a battery, which also powers the power display and the ring electromagnet in the quick-release filter assembly.

The megaphone body is held by a handle, and it is electrically connected to external devices via a wiring hole, thus facilitating the use of the megaphone body.

[0014] Compared with existing technologies, this loudspeaker with a quick-release filter structure is used in a way where a limiting groove in the quick-release filter assembly is cut into the loudspeaker body and magnetically connected to the frame in the filter plate via a ring electromagnet. A snap-fit ​​groove facilitates the installation and removal of the filter plate. The outer layer for filtration blocks oil and large dust particles, the middle layer absorbs moisture and microorganisms, and the inner layer captures PM-level particles. A fine filtration layer filters smaller particles. The pore size of the filter plate decreases from the outside to the inside, thus facilitating the filtration of impurity particles. The funnel-shaped airflow guide also helps to transfer the heat and sound generated by the loudspeaker body. After the frame contacts the limiting groove, the annular electromagnet is activated, causing eight sets of neodymium iron boron magnets to drive the sealing ring to tightly adhere to the inner surface of the limiting groove, thereby ensuring the sealing around the limiting groove. Through the above structure, the problem of "the dust filter function used in loudspeakers in the prior art has the problems of complex maintenance and risk of sealing failure. Among them, the fine filter has strict requirements for pre-filtration, and it is necessary to ensure that the particle size of the incoming particles is smaller than the diameter of the membrane tube. Otherwise, it is easy to clog and obstruct airflow. Moreover, if a single fiber is damaged, the entire membrane module needs to be replaced, which is costly and cumbersome. Furthermore, the peripheral seal of the filter and the fit between the inlet and outlet holes and the support structure are prone to leakage, and it is difficult to reset after disassembly and assembly, affecting the filtration efficiency" is solved.
