[0026] like Figure 1-4 As shown, a sound and light detection tool for buzzers includes a detection platform 1 and a test frame 2 slidably arranged on the detection platform 1.
[0027] Specifically, a plurality of test areas 3 for placing buzzers are formed on the test bench 1, a sound receiving module 4 for receiving the alarm sound of the buzzer, and an indicator light 5 for providing feedback to the sound receiving module 4 are provided on the test stand 2, and the test area 3 is arranged opposite to the sound receiving module 4. When the buzzer sounds an alarm, the sound receiving module 4 receives the sound signal and converts it into an electrical signal and transmits it to the indicator light 5, so that the indicator light 5 lights up.
[0028] By placing a number of buzzers on the test area 3 of the test bench 1 and driving the test frame 2 to move above the test area 3, when the buzzer sounds an alarm, the sound receiving module 4 on the test frame 2 receives the sound signal emitted by the buzzer and converts it into an electrical signal and transmits it to the indicator light 5, making the indicator light 5 light up, thereby realizing automatic detection of the buzzer sound, which has better detection efficiency than manual detection.
[0029] like Figure 1-4 As shown, a further explanation of the implementation method of the movement of the test frame 2 in this embodiment is provided, wherein a driving structure 6 for driving the test frame 2 to move is provided on the test bench 1, and the driving structure 6 includes a slide rail module 101 arranged on the test bench, and a moving unit 102 for driving the test frame 2 to move on the slide rail module 101.
[0030] During the test, multiple buzzers to be tested are placed on the test area 3, and the mobile unit 102 pushes the test frame 2 to move on the slide rail module 101, so that the sound receiving module 4 moves above the buzzer to receive the alarm sound generated by the buzzer, thereby realizing automatic detection of the buzzer.
[0031] like Figure 1-4 As shown, as a further explanation of the installation implementation method of the sound receiving module 4 and the indicator light 5 in this embodiment, a mounting groove 111 is formed on the test frame 2, and the sound receiving module 4 is inserted in the mounting groove 111. The sound receiving module 4 is inserted in the mounting groove 111, and the position of the sound receiving module 4 can be adjusted up and down, and the distance between the sound receiving module 4 and the buzzer can be adjusted.
[0032] Furthermore, a slot 112 is formed on the test frame 2, and the indicator light 5 is inserted into the slot 112, and the slot 112 is connected to the installation slot 111, so that the indicator light 5 can be placed in the slot 112, which improves the convenience of installing the indicator light 5. In addition, the installation slot 111 and the slot 112 are connected, which improves the convenience of connecting the indicator light 5 with the sound receiving module 4.
[0033] Preferably, a positioning groove 110 for placing the buzzer is formed on the test area 3, so as to improve the stability of the placement of the buzzer.
[0034] Preferably, a driving switch 113 for driving the test frame 2 to move is provided on the test platform 1. The driving switch 113 can be pressed to drive the test frame 2 to move, thereby testing the buzzer.
[0035] In addition, in this embodiment, a soundproof cover 103 is provided on the periphery of the test area 3 , and the soundproof cover 103 rises to contact the test frame 2 and forms an independent test cavity 104 , and the sound receiving module 4 is placed in the test cavity 104 .
[0036] During the test, the rising of the soundproof cover 103 will form a separate test chamber 104, which prevents the adjacent buzzer from interfering with the sound receiving module 4, thereby improving the accuracy of the test.
[0037] like Figure 1-4 As shown, further explanation is given to the implementation method of the up and down movement of the sound insulation cover 103 in this embodiment, wherein a sliding groove 105 for the sound insulation cover 103 to slide is formed on the detection platform 1, and a lifting unit 106 for driving the sound insulation cover 103 to move up and down is set at the bottom of the sound insulation cover 103.
[0038] When the test frame 2 is moved to above the test area 3 under the action of the driving structure 6, the lifting unit 106 will drive the sound insulation cover 103 to rise along the sliding groove 105, and the sound insulation cover 103 will cover the tested buzzer and the corresponding sound receiving module 4, so as to realize a one-to-one test of the buzzer by the sound receiving module 4, avoiding the alarm sound of the adjacent buzzer from interfering with the sound receiving module 4, thereby greatly improving the accuracy of the detection.
[0039] Preferably, a sound insulation cotton 107 is attached to the inner wall of the sound insulation cover 103 to prevent the alarm sound emitted by the buzzer in the sound insulation cover 103 from affecting the test of adjacent buzzers.
[0040] Furthermore, a sealing groove 108 is formed on the top of the sound insulation cover 103, and a sealing ring 109 is arranged in the sealing groove 108. When the sound insulation cover 103 abuts against the test frame 2, the sealing ring 109 abuts against the test frame 2, thereby further improving the sound insulation effect and preventing the alarm sound of the buzzer inside the sound insulation cover 103 from affecting the adjacent buzzers.
