Description

Anti-toppling electromagnetic buzzer

Technical Field

The utility model relates to a pronunciation equipment field, concretely relates to buzzer, especially an anti-tilt electromagnetic type buzzer.

Background

The buzzer is an electronic buzzer with an integrated structure, adopts direct current voltage for power supply, and is widely applied to electronic products such as computers, printers, copiers, alarms, electronic toys, automobile electronic equipment, telephones, timers and the like as a sounding device. The buzzer is mainly divided into two types, namely a piezoelectric buzzer and an electromagnetic buzzer. The electromagnetic buzzer is widely used for equipment such as voice, music and the like because of good timbre. However, the existing electromagnetic buzzer is installed on the equipment through the PIN, and the PIN is easily bent by a worker in the process of installing the equipment or in the process of running the equipment, so that the electromagnetic buzzer lies down, and the sounding effect of the equipment is affected.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: in order to avoid the phenomenon that the PIN needle is bent to cause the electromagnetic buzzer to lie down in the process of installing equipment or running the equipment by a worker, the sound production effect of the equipment is improved.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a pair of prevent empting electromagnetic type buzzer, including the electromagnetic type buzzer body, still include connecting terminal, electromagnetic type buzzer body bottom symmetry is seted up flutedly, the recess both ends extend to respectively on the face of the front and back both ends of electromagnetic type buzzer body, connecting terminal card is in and cover entirely in the recess.

Grooves are symmetrically formed in the bottom end of the electromagnetic buzzer body, two ends of each groove extend to the front end face and the rear end face of the electromagnetic buzzer body respectively, and the connecting terminals are clamped in the grooves and completely cover the grooves; the connecting terminal is clamped at the bottom end of the electromagnetic buzzer body in a full-covered mode, the defect that the bottom end of the electromagnetic buzzer body is easily bent due to external force due to the fact that a PIN needle is welded to the bottom end of the electromagnetic buzzer body in a spot mode is overcome, and the sounding effect of the electromagnetic buzzer is effectively guaranteed; meanwhile, the grooves symmetrically formed in the bottom end of the electromagnetic buzzer body are more stable and firm to install on equipment through the connecting terminals, and the electromagnetic buzzer body cannot deviate or fall off due to vibration of the equipment.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

As shown in fig. 1, the utility model provides a pair of prevent empting electromagnetic type buzzer, including electromagnetic type buzzer body 1, still include connecting terminal 3, recess 2 has been seted up to 1 bottom symmetry of electromagnetic type buzzer body, 2 both ends of recess extend to respectively on the face of the front and back both ends of electromagnetic type buzzer body 1, connecting terminal 3 card is in and cover in the recess 2 entirely recess 2.

Grooves 2 are symmetrically formed in the bottom end of the electromagnetic buzzer body 1, two ends of each groove 2 extend to the front end face and the rear end face of the electromagnetic buzzer body 1 respectively, and the connecting terminals 3 are clamped in the grooves 2 and completely cover the grooves 2; the connecting terminal 3 is clamped at the bottom end of the electromagnetic buzzer body 1 in a full-covered mode, the defect that the bottom end of the electromagnetic buzzer body 1 is easily bent due to external force when a PIN needle is welded on the bottom end of the electromagnetic buzzer body in a spot mode is overcome, and the sounding effect of the electromagnetic buzzer is effectively guaranteed; meanwhile, the grooves 2 symmetrically formed in the bottom end of the electromagnetic buzzer body 1 are more stable and firm to install on equipment through the connecting terminals 3, and the electromagnetic buzzer body 1 cannot deviate or fall off due to vibration of the equipment.

As shown in fig. 3, 4 and 5, the connection terminal 3 is first clamped at one end of the groove 2, then bent to cover the groove 2 formed at the bottom end of the electromagnetic buzzer body 1, and finally bent to be clamped at the other end of the groove 2.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
