Description

Technical Field

[0001] This invention belongs to the field of loudspeaker technology, and particularly relates to a push-to-vent loudspeaker. Background Technology

[0002] A loudspeaker, also known as a horn, is a commonly used electroacoustic transducer. It converts electrical signals into sound signals. While the loudspeaker is the weakest component in an audio system, it is also crucial for sound quality. It transmits audio energy through electromagnetic, piezoelectric, or electrostatic effects, causing its cone or diaphragm to vibrate and resonate with the surrounding air to produce sound. Existing loudspeakers often come equipped with dust covers to prevent dust from entering the speaker. However, after a period of use, a large amount of dust accumulates on the outside of the dust cover, affecting the speaker's normal operation. Furthermore, disassembly and installation are inconvenient, hindering quick and easy cleaning. Therefore, it is necessary to upgrade the existing structure to improve its ease of use and flexibility. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the present invention solves the problem of providing a press-to-ventilate speaker that allows for convenient, efficient and flexible cleaning of dust cover dust.

[0004] To solve the above problems, the technical solution adopted by the present invention is as follows: A push-to-open loudspeaker includes a push-to-open base, an assembly cover, a loudspeaker housing, a dust cover, a telescopic ring, an air inlet duct, an exhaust duct, a floating cover, and a telescopic power device. The push-to-open base is elastically telescopically mounted below the assembly cover. The loudspeaker housing is installed inside the upper end of the assembly cover. The dust cover is installed inside the upper end of the loudspeaker housing. An annular vent groove is formed around the lower perimeter of the assembly cover. A telescopic ring is installed around the upper perimeter of the push-to-open base. The telescopic ring is inserted upward into the annular vent groove. Multiple air inlet ducts are evenly connected to the outer perimeter of the annular vent groove. The upper perimeter of the assembly cover is... Multiple exhaust ducts are evenly installed, with their lower ends connected to the upper end of an annular vent groove. The upper ends of the multiple exhaust ducts are connected to a floating cover via telescopic movement. The inner side of the floating cover is connected to the perimeter of the speaker housing, and the floating cover is located on the outer perimeter of the dust cover. A telescopic power device is installed on each of the upper sides of the mounting cover. The telescopic power device drives the floating cover to move up and down. When the pressing base is pressed upward, the pressing base drives the telescopic ring body to press upward, so that the airflow in the annular vent groove enters the floating cover through the multiple exhaust ducts, and the airflow is blown from the floating cover to the dust cover inside the speaker housing.

[0005] Furthermore, lifting blocks are provided on both sides of the floating cover; a positioning ring is provided around the upper end of the assembly cover; longitudinal lifting grooves are opened on both sides inside the positioning ring; a lifting block is slidably installed in each of the longitudinal lifting grooves; a telescopic power device is installed on both sides of the upper end of the positioning ring, the telescopic power device is a telescopic cylinder, the lower end of the telescopic power device extends into the longitudinal lifting groove through a telescopic shaft, and the lower end of the telescopic shaft is connected to the upper side of the lifting block.

[0006] Furthermore, the lower end of the floating cover is uniformly provided with multiple upper guide pipes; the upper end of the exhaust duct is connected to the lower end of the upper guide pipes through telescopic guide pipes.

[0007] Furthermore, elastic guide rods are provided on both sides of the upper end of the pressing base; spring-loaded slots are provided on both sides of the lower end of the assembly cover; a pressure spring is installed in each of the spring-loaded slots; the inner end of the elastic guide rod is slidably inserted into the spring-loaded slot, and the pressure spring elastically presses down against the inner end of the elastic guide rod.

[0008] Furthermore, the longitudinal section of the assembly cover has a U-shaped structure.

[0009] Furthermore, the inner side of the floating cover is evenly provided with multiple air outlet heads; the upper end of the speaker housing is evenly provided with multiple longitudinal through-holes; and air outlet heads are floatingly connected to the longitudinal through-holes respectively.

[0010] Furthermore, the intake duct is equipped with an intake one-way valve; the exhaust duct is equipped with an exhaust one-way valve.

[0011] Furthermore, the upper end of the telescopic ring is provided with a plug-in annular piston; the plug-in annular piston is made of rubber material; and the outer and inner sides of the plug-in annular piston are coated with a wear-resistant coating.

[0012] The beneficial effects of this invention are as follows: This invention allows for convenient cleaning without disassembling the dust cover. By pressing the base upwards, the telescopic ring is pushed upwards, compressing the airflow inside the annular vent groove. This airflow then enters the floating cover through multiple exhaust ducts. The airflow then blows and impacts the speaker housing from the inner perimeter of the floating cover, effectively blowing away dust. Simultaneously, a telescopic power device drives the floating cover to move up and down, allowing it to float and blow dust over a large area without dead angles. When the base is released, a spring presses down against the elastic guide rod, causing the base to return to its original position. Air is then drawn in and stored through the intake duct. This invention is convenient to operate and flexible to use. Attached Figure Description

The inner side of the floating cover 8 is connected to the perimeter of the speaker housing 3, and the floating cover 8 is located on the outer perimeter of the dust cover 4. A telescopic power device 9 is installed on each side of the upper end of the assembly cover 2. The telescopic power device 9 drives the floating cover 8 to move up and down. When the pressing base 1 is pressed upward, the pressing base 1 drives the telescopic ring 5 to press upward, so that the airflow in the annular ventilation groove 21 enters the floating cover 8 through the multiple exhaust ducts 7, and the airflow is blown from the floating cover 8 to the dust cover 4 inside the speaker housing 3.

[0020] like Figures 1 to 5As shown, to facilitate the up-and-down driving control of the floating cover 8, lifting blocks 81 are provided on both sides of the floating cover 8; a positioning ring 22 is provided around the upper end of the assembly cover 2; longitudinal lifting grooves 221 are opened on both sides of the interior of the positioning ring 22; a lifting block 81 is slidably installed in the longitudinal lifting groove 221; a telescopic power device 9 is installed on both sides of the upper end of the positioning ring 22, the telescopic power device 9 is a telescopic cylinder, the lower end of the telescopic power device 9 extends into the longitudinal lifting groove 221 through a telescopic shaft 91, and the lower end of the telescopic shaft 91 is connected to the upper side of the lifting block 81.
