Embodiment Construction

[0033] In order to make the purpose, technical solution and advantages of the present invention clearer, the buzzer detection device of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] In one embodiment, such as figure 1 As shown, a buzzer detection device is provided, including: an acoustic-to-electric conversion circuit 100 for collecting the sound signal of the buzzer and converting the sound signal into an electrical signal. The detection circuit 200 is connected with the acoustic-electric conversion circuit 100, and is used to obtain the frequency signal of the buzzer according to the electrical signal, and detect whether the frequency signal falls within the preset frequency range, if so, determine that the buzzer is qualified, otherwi...

Abstract

The invention provides a detection device for a buzzer, comprising: an acoustic-electric conversion circuit for collecting the sound signal of the buzzer and converting the sound signal into an electrical signal; a detection circuit connected with the acoustic-electric conversion circuit for Obtain the frequency signal of the buzzer according to the electrical signal, and detect whether the frequency signal falls within the preset frequency range, if so, determine that the buzzer is qualified, otherwise, determine that the buzzer is unqualified. It effectively avoids the misjudgment and missed detection caused by manual monitoring of the buzzer, realizes the rapid and automatic detection of the buzzer, effectively improves the detection efficiency of the buzzer, and reduces the labor intensity of the staff. At the same time, it can also detect The sound of different coded main boards and different types of buzzers realizes the automatic switching of sound detection of different coded main boards and different types of buzzers, and is in line with automatic detection.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a detection device for a buzzer. Background technique [0002] When the air conditioner is turned on and off, the temperature and humidity are adjusted, or the air conditioner breaks down, in order to realize the response to the remote control command or remind the user of the failure of the air conditioner, a buzzer is usually installed on the main board of the air conditioner. The traditional buzzers installed on the main board of the air conditioner generally include: active electromagnetic buzzers, passive electromagnetic buzzers and piezoelectric ceramic buzzers. [0003] When testing the buzzer of the main board of the air conditioner, it is usually judged whether the buzzer is qualified by manual monitoring to meet the functional requirements of the main board of the air conditioner. Manual monitoring will cause misjudgment or missed detection, especially in the producti...
