Description

Technical Field

[0001] This utility model relates to the field of acoustic engineering technology, and in particular to a broadband acoustic coupler. Background Technology

[0002] An acoustic coupler is a device used to connect two acoustic systems, enabling sound waves to be transmitted efficiently between them and achieving specific acoustic functions.

[0003] Most acoustic couplers achieve rigid connection of acoustic elements through threaded connections, flange bolt fixation, or adhesive bonding. Although this type of structure can ensure the stability of acoustic transmission, it requires disassembly and removal of the bolts one by one, making disassembly and maintenance quite troublesome.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: most acoustic couplers achieve rigid connection of acoustic elements through threaded connection, flange bolt fixing or adhesive bonding. Although such structures can ensure the stability of acoustic transmission, the bolts need to be removed one by one during disassembly. Therefore, a broadband acoustic coupler is proposed to address the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing acoustic couplers, which rely on threaded connections, flange bolts, or adhesive bonding to achieve rigid connections of acoustic elements. While such structures can ensure the stability of acoustic transmission, they require the bolts to be removed one by one during disassembly. Therefore, this invention proposes a broadband acoustic coupler.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a broadband acoustic coupler, comprising a coupler body, an output terminal and an input terminal electrically connected to both sides of the coupler body respectively, two guide grooves formed on the surface of the coupler body, guide rods slidably connected in both guide grooves, one end of the guide rods being fixedly connected to a housing, a snap-fit ​​groove formed on the surface of the coupler body, a snap-fit ​​plate slidably connected to the inner wall of the snap-fit ​​groove, one side of the snap-fit ​​plate being fixedly connected to the housing, the snap-fit ​​plate being made of a soft material, and sound-absorbing cotton being adhered to the inner cavity of the coupler body.

[0007] The aforementioned components achieve the following effects: the sliding guide rod and snap-fit ​​plate structure enables flexible disassembly and secure connection between the outer shell and the coupler body, facilitating equipment installation, debugging, and maintenance. Simultaneously, the snap-fit ​​plate, made of a soft material, buffers impact forces during installation, reducing component wear. Furthermore, the sound-absorbing cotton adhered to the inner cavity effectively absorbs noise and ripples generated during acoustic signal transmission, improving the purity and transmission quality of the acoustic signal, thereby optimizing the overall performance of the broadband acoustic coupler.

[0008] Preferably, the surface of the coupler body is provided with an adsorption groove, an adsorption sheet is fixedly installed on the inner wall of the adsorption groove of the coupler body, and a magnetic adsorption sheet is fixedly connected to one side of the outer shell.

[0009] The effect achieved by the above components is that the combination of the adsorption plate and the magnetic plate improves the stability of the connection between the outer shell and the coupler body.

[0010] Preferably, a spring is fixedly connected to the inner wall of the snap-fit ​​plate, and the size of the guide rod is adapted to the size of the guide groove of the coupler body.

[0011] The effect achieved by the above components is that by setting springs, the service life of the snap-fit ​​plate is increased, material fatigue of the snap-fit ​​plate due to long-term use is avoided, and the practicality of the device is improved.

[0012] Preferably, a sealing gasket is fixedly connected to one side of the housing, and one side of the sealing gasket is in contact with the coupler body.

[0013] The effect achieved by the above components is that by setting a sealing gasket, a seal is achieved when the outer shell is connected to the coupler body, preventing dust or other impurities from entering the coupler body and improving the practicality of the device.

[0014] Preferably, both the output and input ends are covered with protective sleeves, and the protective sleeves are made of rubber.

[0015] The effect achieved by the above-mentioned components is that by setting up protective sleeves, the output and input ends are sealed and protected, thereby improving the practicality of the device.

[0016] Preferably, a heat sink is fixedly connected to one side of the coupler body, and a plurality of heat dissipation fins are fixedly connected to the surface of the heat sink.

[0017] The effect achieved by the above components is as follows: by setting heat sinks and several heat dissipation fins on one side of the coupler body, the heat dissipation efficiency of the equipment is greatly improved. The heat sink increases the heat dissipation area, and the dense heat dissipation fins further enhance air convection, which can quickly dissipate the heat generated by the coupler during operation into the environment, avoiding the performance degradation or damage of internal components due to excessive temperature, thereby ensuring the stability and reliability of the broadband acoustic coupler under long-term operation and extending the service life of the equipment.

[0018] In this invention, the sliding guide rod and snap-fit ​​plate structure enable flexible disassembly and secure connection between the outer shell and the coupler body, facilitating equipment installation, debugging, and maintenance. Simultaneously, the snap-fit ​​plate, made of a soft material, buffers impact forces during installation, reducing component wear. Furthermore, the sound-absorbing cotton adhered to the inner cavity effectively absorbs noise and ripples generated during acoustic signal transmission, improving the purity and transmission quality of the acoustic signal, thereby optimizing the overall performance of the broadband acoustic coupler.

[0025] Reference Figure 1-5As shown, this utility model provides a technical solution: a broadband acoustic coupler, including a coupler body 1, with an output terminal 2 and an input terminal 3 electrically connected to both sides of the coupler body 1, respectively. Two guide grooves are formed on the surface of the coupler body 1, and guide rods 5 are slidably connected in both guide grooves of the coupler body 1. One end of the guide rod 5 is fixedly connected to a housing 4. A snap-fit ​​groove is formed on the surface of the coupler body 1, and a snap-fit ​​plate 6 is slidably connected to the inner wall of the snap-fit ​​groove of the coupler body 1. One side of the snap-fit ​​plate 6 is fixedly connected to the housing 4. The snap-fit ​​plate 6 is made of a soft material, and sound-absorbing cotton 11 is adhered to the inner cavity of the coupler body 1. The sliding guide rod 5 and the snap-fit ​​plate 6 structure enable flexible disassembly and secure connection between the outer shell 4 and the coupler body 1, facilitating equipment installation, debugging, and maintenance. Simultaneously, the snap-fit ​​plate 6, made of a soft material, buffers impact forces during installation, reducing component wear. Furthermore, the sound-absorbing cotton 11 adhered to the inner cavity effectively absorbs noise and ripples generated during acoustic signal transmission, improving the purity and transmission quality of the acoustic signal, thereby optimizing the overall performance of the broadband acoustic coupler. The surface of the coupler body 1 has an adsorption groove, and an adsorption sheet 10 is fixedly installed on the inner wall of the adsorption groove. A magnetic suction sheet 9 is fixedly connected to one side of the outer shell 4. The cooperation between the adsorption sheet 10 and the magnetic suction sheet 9 improves the stability of the connection between the outer shell 4 and the coupler body 1. A spring 7 is fixedly connected to the inner wall of the snap-fit ​​plate 6, and the size of the guide rod 5 is adapted to the size of the guide groove in the coupler body 1. By incorporating spring 7, the service life of the snap-fit ​​plate 6 is increased, preventing material weakening due to prolonged use and improving the practicality of the device. A sealing gasket 8 is fixedly connected to one side of the outer casing 4, and one side of the sealing gasket 8 is in contact with the coupler body 1. The sealing gasket 8 achieves a sealing effect when the outer casing 4 is connected to the coupler body 1, preventing dust or other impurities from entering the coupler body 1 and improving the practicality of the device. Protective sleeves made of rubber are fitted onto the surfaces of both the output end 2 and the input end 3. These protective sleeves provide a sealed protection for the output end 2 and the input end 3, improving the practicality of the device. A heat sink 13 is fixedly connected to one side of the coupler body 1, and several heat dissipation fins are fixedly connected to the surface of the heat sink 13. By setting a heat sink 13 and several heat dissipation fins on one side of the coupler body 1, the heat dissipation efficiency of the device is greatly improved. The heat sink 13 increases the heat dissipation area, and the dense heat dissipation fins further enhance air convection, which can quickly dissipate the heat generated by the coupler during operation into the environment, avoiding the performance degradation or damage of internal components due to excessive temperature, thereby ensuring the stability and reliability of the broadband acoustic coupler under long-term operation and extending the service life of the device.

[0026] Working principle: When the broadband acoustic coupler is working, output terminal 2 and input terminal 3 realize signal input and output. The guide rod 5 slides in the guide groove, which can drive the housing 4 to move relative to the coupler body 1. The snap-fit ​​plate 6 slides in the snap-fit ​​groove, using its soft material to buffer the installation impact force, realizing flexible disassembly and assembly and stable connection between the housing 4 and the coupler body 1. The spring 7 can prevent the snap-fit ​​plate 6 from becoming soft after long-term use, extending its service life. The adsorption plate 10 and the magnetic adsorption plate 9 cooperate to enhance the stability of the connection between the housing 4 and the coupler body 1. The sealing gasket 8 provides a seal between the housing 4 and the coupler body 1. The connection of the coupler body 1 is sealed to prevent dust and other impurities from entering the interior of the coupler body 1. The protective sleeve provides sealing protection for the output end 2 and the input end 3. When the acoustic signal is transmitted in the coupler body 1, the sound-absorbing cotton 11 in the inner cavity can absorb the noise and ripples generated during transmission, improving the purity and transmission quality of the acoustic signal. At the same time, the heat sink 13 and heat dissipation fins on one side of the coupler body 1 can quickly dissipate the heat generated during the operation of the equipment by increasing the heat dissipation area and enhancing air convection, ensuring the stability and reliability of the equipment under long-term operation and extending its service life.
