Description

Technical Field

[0001] This utility model relates to the field of microphone technology, specifically a microphone with a built-in spiral protective structure. Background Technology

[0002] A microphone is a device that converts sound waves into electrical signals. It is widely used in audio, communication, security and other fields. It is a device used to collect ambient sound and transmit it to back-end equipment. It consists of a microphone and an audio amplification circuit. Microphones are generally divided into digital microphones and analog microphones. Digital microphones are sound sensing devices that convert analog audio signals into digital signals and perform corresponding digital signal processing through a digital signal processing system. Analog microphones simply amplify the collected sound using ordinary analog circuits.

[0003] Existing microphones do not have corresponding protective structures, and cannot absorb or disperse the impact of external forces on the microphone body. When the microphone is hit, it is easily damaged, affecting its service life and making it unsuitable for use in situations where it is frequently moved or easily damaged. Utility Model Content

[0004] The purpose of this invention is to provide a microphone with a built-in spiral protective structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A microphone with a built-in spiral protective structure includes a microphone body, a protective shell on the outside of the microphone body, an external thread on the outside of the protective shell, a fastening nut on the external thread, the microphone body being mounted inside a panel opening through the protective shell, shock-absorbing foam on the circuit board of the microphone body, a microphone cable plug at the bottom of the protective shell, a waterproof connector at the bottom of the microphone cable plug, and a cable connected to the microphone body, the cable passing sequentially through the microphone cable plug and the waterproof connector.

[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0008] In one alternative: the protective housing has an internal mounting groove and an internal thread, and the microphone cable plug has an external thread that mates with the internal thread.

[0009] In one alternative: the shock-absorbing foam is engaged inside the mounting groove.

[0010] In one alternative: the waterproof connector is connected to the microphone cable plug via threads.

[0011] In one alternative: one end of the cable is soldered to the circuit board of the microphone body, and the shock-absorbing foam is adhered to the circuit board.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The microphone with a built-in spiral protective structure consists of a spiral protective shell and a microphone body. The protective shell is made of aluminum alloy, which has excellent corrosion resistance, wear resistance and high strength. It has a compact structure and is easy to assemble. The microphone body is covered with shock-absorbing foam and fixed in the square slot of the protective shell. When the spiral protective shell collides with external objects, it reduces the impact force on the microphone body and avoids damage due to collision.

[0014] 2. The protective structure can effectively absorb and disperse the impact of external forces on the microphone body, extending the service life of the microphone. It is especially suitable for use in environments that require frequent handling or are easily damaged. The protective structure can also prevent the microphone from being damaged by environmental factors (such as humidity, dust, etc.), ensuring the stability of the microphone and the accuracy of the sound quality.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. In the drawings and description, similar or identical parts are referred to by the same reference numerals, and in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this utility model are merely illustrative and not intended to limit the scope of this utility model. Any obvious modifications or changes made to this utility model do not depart from its spirit and scope.

[0024] In one embodiment, such as Figure 1-7 As shown, a microphone with a built-in spiral protective structure includes a microphone body 2, an outer protective shell 1, and an external thread 101 on the outer surface of the outer protective shell 1. The spiral protective shell 1 is made of 5052 aluminum alloy, which has excellent corrosion resistance, wear resistance, and high strength. It has a compact structure and is easy to assemble, thus achieving the function of protecting the hardware. A fastening nut 5 is fitted on the external thread 101. The protective shell 1 is inserted into the opening of the panel. By tightening the fastening nut 5 upwards, the microphone is fixed on the panel with the pre-drilled opening. Shock-absorbing foam 3 is provided on the circuit board of the microphone body 2. A microphone cable plug 4 is provided at the bottom of the protective shell 1. A waterproof connector 6 is provided at the bottom of the microphone cable plug 4. A cable 7 is connected to the microphone body 2. The cable 7 passes through the microphone cable plug 4 and the waterproof connector 6 in sequence.

[0025] The microphone with a built-in spiral protective structure consists of a spiral protective shell 1 and a microphone body 2. The circuit board of the microphone body 2 is covered with shock-absorbing foam 3 and fixed in the square slot (i.e., mounting slot 103) of the protective shell 1. When the spiral protective shell 1 collides with external objects, it reduces the impact force on the microphone body 2 and prevents the microphone from being damaged by the collision. The protective structure can also prevent the microphone from being damaged by environmental factors (such as humidity, dust, etc.), ensuring the stability of the microphone and the accuracy of the sound quality. As an embodiment, the left, right, up, and down positions of the various components shown in the attached figure are only a kind of arrangement. The specific positions are set according to specific needs.

[0026] In one embodiment, such as Figure 1-6 As shown, the protective housing 1 has an internal mounting groove 103 and an internal thread 102, the microphone cable plug 4 has an external thread that mates with the internal thread 102, and the shock-absorbing foam 3 is engaged inside the mounting groove 103.

[0027] In one embodiment, such as Figure 1-3 As shown, the waterproof connector 6 and the microphone cable plug 4 are connected by threads.

[0028] In one embodiment, such as Figure 1-2 As shown, one end of the cable 7 is soldered to the circuit board of the microphone body 2, and the shock-absorbing foam 3 is pasted on the circuit board.

[0029] The above embodiments of this utility model provide a microphone with a built-in spiral protective structure. One end of the cable 7 is soldered to the circuit board of the microphone body 2. Then, shock-absorbing foam 3 is pasted on the circuit board. The cable 7 is then passed through the microphone cable plug 4 and the waterproof connector 6 in sequence. The waterproof connector 6 is installed on the microphone cable plug 4. The assembled components are installed inside the spiral protective shell 1 (i.e., the M20 internal thread hole). Finally, the fastening nut 5 (M28 bolt) is installed on the external thread 101 of the spiral protective shell 1 and rotated to the end position, thus achieving the fixed installation of the entire microphone.

[0030] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure.
