Abstract

The invention discloses a buzzer capable of adjusting sound wave intensity and used for a household appliance. The buzzer comprises a buzzer main body, a nut, a vibrating diaphragm, a magnet and a bottom plate, and is characterized in that the outer side of the buzzer main body is provided with a fixed plate, the outer side of the buzzer main body is provided with a first threaded rod, and the lower end of the buzzer main body is provided with a movable cover; a circuit board is arranged in the buzzer main body, a second threaded rod is arranged on the outer side of the buzzer main body, a limiting rod is arranged on the outer side of the buzzer main body, pins are arranged in the buzzer main body, a magnet is arranged in the buzzer main body, and a bottom plate is arranged in the buzzer main body. According to the buzzer capable of adjusting the sound wave intensity and used for the household appliance, the movable cover and the second threaded rod are arranged, and the second threaded rod can limit the buzzer through the limiting rod and the second threaded rod, so that the movable cover is prevented from moving, and the pins can be protected; and the pins are protected when the buzzer is not used, and the pins are prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of buzzers, in particular to a buzzer for household appliances with adjustable sound wave intensity. 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 current buzzer is difficult to adjust the sound wave intensity and is inconvenient to use. [0003] But existing buzzer has the following deficiencies in use, for example; [0004] (1) It is inconvenient to adjust the sound wave intensity. It is inconvenient to adjust the sound wave intensity of the existing buzzer during use, which causes inconvenience in use. [0005] (2) It is inconvenient to store the ...
