Description

Technical Field

[0001] This application relates to the field of testing fixtures, and in particular to a volume testing fixture for a finished microphone intercom system. Background Technology

[0002] A microphone (scientifically known as a transducer) is an energy conversion device that converts sound signals into electrical signals. It is widely used in recording, communication, and amplification. The core function of a microphone is to convert sound wave vibrations into electrical signals through the principle of sound-to-electricity conversion. According to the International Electrotechnical Commission (IEC) standards, microphones are a type of electroacoustic transducer, mainly classified into dynamic, condenser, and electret types. Microphones require volume testing after production to ensure they are functional.

[0003] Existing microphones, when used for intercom volume detection, are fixed in a fixture, and the computer controls the speaker to emit sound so that the microphone can pick up the sound. The sound is then transmitted to the speaker for playback, and the volume of the played sound is detected by a decibel meter. However, the microphone is difficult to move during sound pickup, making it impossible to detect the sound pickup effect at different angles, which reduces the detection efficiency. Utility Model Content

[0004] To address the aforementioned issues, this application provides a fixture for detecting the volume of a finished microphone intercom system.

[0005] The volume detection fixture for the finished microphone intercom system provided in this application adopts the following technical solution:

[0006] A finished microphone intercom system volume detection fixture includes a housing and a microphone. The housing is equipped with a detection component for detecting the microphone volume and an adjustment component for adjusting the microphone angle. The adjustment component includes a swing tube that is oscillatingly connected inside the housing. Rotating rings are rotatably connected to both ends inside the swing tube. Clamping components are provided on the rotating rings. An electric telescopic rod is fixedly connected to the top of the housing. The output end of the electric telescopic rod is located inside the housing and is hinged to a connecting rod. The other end of the connecting rod is hinged to the swing tube.

[0007] By adopting the above technical solution, during use, the microphone is clamped and fixed in two rotating rings by the clamping assembly, and the microphone volume is detected by the detection assembly. During the detection process, the electric telescopic rod is activated to push the swing tube to swing inside the housing, causing the microphone to swing and the microphone angle to be adjusted. The sound pickup effect of the microphone at different angles is detected, which avoids the problem of not being able to detect the sound pickup effect of the microphone at different angles, thus reducing the detection efficiency.

[0008] Preferably, a motor is installed on one side wall of the swing tube, and a gear is fixedly connected to the output end of the motor. One end of the rotating ring extends out of the swing tube and is fixedly connected to a gear ring, and the gear meshes with the gear ring.

[0009] By adopting the above technical solution, when the microphone swings, the motor is started at the same time, and the gear drives the gear ring to rotate, causing the rotating ring to rotate and driving the microphone to rotate, which can improve the microphone's sound pickup angle.

[0010] Preferably, the detection component includes a first playback speaker installed on one side wall inside the housing, a partition plate fixedly connected inside the housing, a second playback speaker installed on one side wall of the partition plate, the second playback speaker being connected to the microphone signal, and a decibel meter installed on the side wall inside the housing near the second playback speaker.

[0011] By adopting the above technical solution, an external computer is connected to the first speaker, which then plays sound. The sound is then picked up by a microphone and played by the second speaker. The volume of the sound is detected by a decibel meter, which is used to detect the volume of the microphone intercom system.

[0012] Preferably, the clamping assembly includes two arc-shaped clamping plates disposed inside the rotating ring. The arc-shaped clamping plates are disposed opposite each other and a mounting rod is hinged to one side wall. The end of the mounting rod away from the arc-shaped clamping plate is fixedly connected to the rotating ring. A spring is fixedly connected to one side wall of the arc-shaped clamping plate on the side of the mounting rod. The end of the spring away from the arc-shaped clamping plate is fixedly connected to the rotating ring.

[0013] By adopting the above technical solution, the arc-shaped clamp is pushed by a spring, causing the arc-shaped clamp to swing on the mounting rod. The arc-shaped clamp is tilted and then the microphone is inserted from one end of the swing tube, so that one end of the microphone presses against the raised end of the arc-shaped clamp. While the arc-shaped clamp is swinging, the spring contracts, bringing the arc-shaped clamp into contact with the microphone, which facilitates the clamping of the microphone.

[0014] Preferably, elastic rubber pads are fixedly connected to the sidewalls of the two arc-shaped clamps on opposite sides.

[0015] By adopting the above technical solution, the elastic rubber pad prevents the curved clamp from directly contacting the microphone and causing wear to the microphone. At the same time, the elastic rubber pad is squeezed and deformed when it comes into contact with the microphone, which improves the clamping stability.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. This application utilizes the cooperative arrangement of structures such as the swing tube, rotating ring, and electric telescopic rod. During use, the microphone is clamped and fixed in two rotating rings by the clamping assembly, and the microphone volume is detected by the detection assembly. During the detection process, the electric telescopic rod is activated to push the swing tube to swing within the housing, causing the microphone to swing and adjusting its angle. This allows for the detection of the microphone's sound pickup effect at different angles, thus minimizing the problem of reduced detection efficiency caused by the inability to detect the microphone's sound pickup effect at different angles.

[0018] 2. The curved clamp is pushed by the spring, causing it to swing on the mounting rod. The curved clamp is tilted and then the microphone is inserted from one end of the swing tube, so that one end of the microphone presses against the raised end of the curved clamp. While the curved clamp is swinging, the spring contracts, bringing the curved clamp into contact with the microphone, making it easy to hold the microphone. Attached Figure Description

[0023] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0024] This application discloses a volume detection fixture for a finished microphone intercom system.

[0025] Reference Figure 1 , Figure 2 and Figure 3 The finished microphone intercom system volume detection fixture includes a housing 1 and a microphone 2. The housing 1 is equipped with a detection component for detecting the volume of the microphone 2 and an adjustment component for adjusting the angle of the microphone 2. The adjustment component includes a swing tube 3, a rotating ring 4, an electric telescopic rod 5 and a connecting rod 6.

[0026] The swing tube 3 is located inside the housing 1. Two ring-shaped swing rods (not shown in the figure) are fixedly connected to the middle section of the side wall of the swing tube 3. The ends of the swing rods away from the swing tube 3 are rotatably connected to the two side walls of the housing 1 respectively. Two rotating rings 4 are provided, which are rotatably connected to the two ends inside the swing tube 3. The rotating rings 4 are equipped with clamping components. The electric telescopic rod 5 is fixedly connected to the top of the housing 1. The output end of the electric telescopic rod 5 is located inside the housing 1 and is hinged to the connecting rod 6. The other end of the connecting rod 6 is hinged to the swing tube 3.

[0027] Reference Figure 1 and Figure 2 A motor 7 is installed on one side wall of the swing tube 3. A gear 8 is fixedly connected to the output end of the motor 7. One end of a rotating ring 4 extends out of the swing tube 3 and is fixedly connected to a toothed ring 9. The gear 8 meshes with the toothed ring 9. When the microphone 2 swings, the motor 7 is started at the same time. The gear 8 drives the toothed ring 9 to rotate, causing the rotating ring 4 to rotate, which in turn drives the microphone 2 to rotate, thereby increasing the sound pickup angle of the microphone 2.

[0028] Reference Figure 1 The detection component includes a first speaker 10 installed on one side wall inside the housing 1. A partition plate 11 is fixedly connected inside the housing 1. A second speaker 12 is installed on one side wall of the partition plate 11. The second speaker 12 is connected to the microphone 2. A decibel meter 13 is installed on the side wall inside the housing 1 near the second speaker 12. By connecting an external computer to the first speaker 10, the first speaker 10 plays sound. Then, the microphone 2 picks up the sound, causing the second speaker 12 to play it. The decibel meter 13 detects the volume of the microphone 2 intercom system.

[0029] Reference Figure 1 , Figure 2 and Figure 3 The clamping assembly includes two arc-shaped clamps 14 disposed inside the rotating ring 4. The arc-shaped clamps 14 are disposed opposite each other and a mounting rod 15 is hinged to one side wall. The end of the mounting rod 15 away from the arc-shaped clamps 14 is fixedly connected to the rotating ring 4. A spring 16 is fixedly connected to one side wall of the arc-shaped clamps 14 located on the side of the mounting rod 15. The end of the spring 16 away from the arc-shaped clamps 14 is fixedly connected to the rotating ring 4. The spring 16 pushes the arc-shaped clamps 14, causing the arc-shaped clamps 14 to swing on the mounting rod 15. The arc-shaped clamps 14 are tilted. Then, the microphone 2 is inserted from one end of the swing tube 3, so that one end of the microphone 2 presses against the tilted end of the arc-shaped clamps 14. While the arc-shaped clamps 14 are swinging, the spring 16 contracts, bringing the arc-shaped clamps 14 into contact with the microphone 2, which facilitates clamping the microphone 2.

[0030] Reference Figure 2 and Figure 3On the opposite sidewalls of the two arc-shaped clamps 14, elastic rubber pads 17 are fixedly connected. The elastic rubber pads 17 prevent the arc-shaped clamps 14 from directly contacting the microphone 2 and causing wear to the microphone 2. At the same time, the elastic rubber pads 17 are squeezed and deformed when they come into contact with the microphone 2, which improves the clamping stability.

[0031] The implementation principle of the finished microphone intercom system volume detection fixture in this application embodiment is as follows: In use, the microphone 2 is inserted from one end of the swing tube 3, causing one end of the microphone 2 to press against the raised end of the arc-shaped clamp 14. While swinging the arc-shaped clamp 14, the spring 16 contracts, causing the arc-shaped clamp 14 to abut against the microphone 2, clamping the microphone 2 and fixing it in two rotating rings 4. By connecting an external computer to the first playback speaker 10, the first playback speaker 10 plays sound, which is then picked up by the microphone 2, causing the second playback speaker 12 to play. The volume of the sound is detected by the decibel meter 13, detecting the volume of the microphone 2 intercom system. During the detection process, the electric telescopic rod 5 is activated, pushing the swing tube 3 to swing inside the housing 1, causing the microphone 2 to swing. At the same time, the motor 7 is activated, and the gear 8 drives the gear ring 9 to rotate, causing the rotating ring 4 to rotate, driving the microphone 2 to rotate, adjusting the angle of the microphone 2, and detecting the sound pickup effect of the microphone 2 at different angles. This avoids the problem of not being able to detect the sound pickup effect of the microphone 2 at different angles, which would reduce the detection efficiency.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
