Abstract

The invention discloses a sound production adjusting device of a magnetic type buzzer for instrument equipment and an adjusting method thereof. The sound production adjusting device comprises a device shell, a through hole and a connecting hole; and the upper surface of an electrifying sheet is provided with the through hole, and the upper surface of the device shell is provided with the connecting hole. The sound production adjusting device of the magnetic type buzzer for the instrument equipment is provided with connecting wires, the number of resistors on the connecting wires is different, and a rotating ring is connected with the electrifying piece; the rotating ring is rotated to enable the electrifying piece to be connected with different connecting wires, and therefore the purpose of adjusting the volume is achieved; a second limiting rod is arranged at the bottom of the device shell; a positioning block is arranged on the outer side face of the rotating ring, so that the electrifying piece can accurately move to the connecting position; a first limiting rod is arranged, and the first limiting rod can ascend and descend through a telescopic spring, so that circuit connection can be completed, the position of the rotating ring can be limited, and dislocation of the rotating ring is avoided; and the connecting plate is arranged, and the length of the connecting plate can be adjusted, so that the mounting distance of the device can be adjusted.

Description

technical field [0001] The invention relates to the technical field of a sounding adjustment device for a magnetic buzzer, in particular to a sounding adjustment device for a magnetic buzzer for instrument equipment and an adjusting method thereof. Background technique [0002] The buzzer is an electronic sounder with an integrated structure. It is powered by DC voltage and is widely used as a sounding device in electronic products such as computers, printers, copiers, alarms, electronic toys, automotive electronic equipment, telephones, and timers. . Buzzers are mainly divided into two types: piezoelectric buzzers and electromagnetic buzzers. The buzzer is represented by the letter "H" or "HA" in the circuit (the old standard uses "FM", "ZZG", "LB", "JD", etc.). The piezoelectric buzzer is mainly composed of a multivibrator, a piezoelectric buzzer, an impedance matcher, a resonance box, and a casing. Some piezoelectric buzzer housings are also equipped with light-emittin...
