Abstract
The utility model provides a buzzer, comprising an upper cover, a stem, a coil, a vibrating diaphragm sheet, a baseplate, patch pins, a magnetic ring, a housing, a wiring board, and a lower cover. The upper side of the magnetic ring of the buzzer is provided with the housing. The housing is a metal housing which makes a louder sound. The center of the housing and the center of the upper cover are provided with sound holes, so tone quality is better. The upper cover and the lower cover are made of high-temperature resistance plastics, preventing generation of static electricity. A patch pin type is used, and a pin type of contact pin type in the prior art can be replaced by the patch pin type. The buzzer enables automated welding, and improves production efficiency and product quality.
Description
Technical field
The utility model is a kind of hummer, is specifically related to the hummer of a kind of auditory tone cues and warning use, belongs to sound and passes to device.
Background technology
Hummer be mainly used in the alarm functions such as warning horn, electrical home appliances.Hummer probably can be divided into two kinds of different patterns, and the first is piezo buzzer, and the second is electromagnetic buzzer.Piezoelectric type buzzing is that piezoelectric ceramic piece after high pressure extreme pressure is pasted on vibration sheet metal, after adding alternating voltage, can be because of piezoelectric effect, producing mechanically deform stretches and shrinks, utilize this characteristic to make to vibrate sheet metal vibration and send the sound, making people can hear sound, but the poor shortcoming of the single tone color of piezo buzzer tone color, and dust easily enters by hole and enters enclosure interior, cause the damage of hummer.Electromagnetic buzzer is coil to be placed in to small iron plate and the vibrating membrane composition of permanent magnet, iron core, high magnetic conduction, it is close to iron core that small iron plate and vibrating membrane are subject to the attraction meeting in magnetic field, coil is accepted vibration signal can produce alternately magnetic field, and take electric energy conversion is acoustic energy, thereby sends sound.
The sound of existing electromagnetic buzzer is smaller, and circuit board structure is complicated.And hummer is metal shell, easily produces static, larger on the impact of hummer life-span.In addition, the pin mode of existing hummer is contact pin, when producing, cannot use paster automatic welding, can only manual welding, be inconvenient to produce.
Utility model content
The utility model, for the problems referred to above, provides a kind of electromagnetic buzzer, and this hummer line construction is simple, rational in infrastructure, and the tonequality sent is good and sound is loud and clear, and whole hummer is produced convenient.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of hummer, described hummer comprises upper cover, lower cover, stem stem, coil, vibrating diaphragm sheet, base plate, terminal block, described lower cover upper surface is provided with terminal block, and the upper surface of terminal block is fixedly connected with base plate, and the central part of the upper surface of base plate is provided with stem stem, stem stem overcoat has coil, coil periphery is provided with magnet ring, and case is stamped in magnet ring upper end, and case can reflect the sound that vibrating diaphragm sheet sends, make it to empathize, thereby improve sound; Between magnet ring and case, be provided with vibrating diaphragm sheet; The terminals of coil are connected with terminal block through bottom plate hole; On described terminal block, be fixed with paster pin, adopt this pin pattern, can replace the pin pattern of contact pin type in prior art, realize automatic welding.
Preferably, described upper cover is fixedly connected with lower cover, and the middle part of upper cover is provided with vocal hole.
Preferably, described case is provided with through hole, and case is metal material, can make vibrating diaphragm sheet reflect its sound when vibration, makes sound louder and clearer.
Preferably, described upper cover, lower cover are high-temperature resistance plastice material, can prevent the generation of static.
Preferably, between described magnet ring, upper cover, lower cover and base plate, all adopt cementing agent to be fixed connection.
The beneficial effect that the utility model hummer can produce is: the magnet ring upside of this hummer is stamped case, adopts metal case, can make the sound that sends louder and clearer, and the central authorities of case and upper cover are equipped with vocal hole, can make the tonequality sent better; Described upper cover, lower cover are high-temperature resistance plastice material, can prevent the generation of static, adopt paster pin pattern, can replace the pin pattern of contact pin type in prior art, realize automatic welding, improve production efficiency and product quality.
Accompanying drawing explanation
Fig. 1 is the inner structure schematic diagram of hummer.
Fig. 2 is hummer external form schematic diagram.
Embodiment
Fig. 1 is the inner structure schematic diagram of hummer, Fig. 2 is hummer external form schematic diagram, Fig. 1 comprises upper cover 1, stem stem 2, coil 3, vibrating diaphragm sheet 9, base plate 5, paster pin 6, magnet ring 4, case 10, terminal block 7, lower cover 8, the upper surface of described lower cover 8 is connected with terminal block 7, the upper surface of terminal block 7 is fixedly connected with base plate 5 use adhesives, the central part of the upper surface of base plate 5 is provided with stem stem 2, stem stem 2 overcoats have coil 3, the outer magnet ring 4 that is arranged with of coil 3, case 10 is stamped in magnet ring 4 upper ends, described case 10 is metal material, and case is provided with through hole, make vibrating diaphragm sheet 9 can reflect and propagate its sound when vibration vibration, between magnet ring 4 and case 10, be provided with vibrating diaphragm sheet 9, the terminals of coil 3 are connected with terminal block 7 through base plate 5 holes, described paster pin 6 adopts automatic welding technique to be fixed on terminal block 7, can improve production efficiency and product quality.Upper cover 1 is connected by binder-reinforced with lower cover 8, and the middle part of upper cover 1 is provided with vocal hole, and upper cover 1 is high-temperature resistance plastice material with lower cover 8, can prevent the generation of static.
When paster pin 6 has current signal to pass through, coil 3 produces the magnetic field with magnet ring 4 opposite directions, weaken the attractive force of vibrating diaphragm sheet 9 total magnetic field, add the elasticity of vibrating diaphragm sheet 9 own, vibrating diaphragm sheet 9 can vibrate, promote air and produce acoustic pressure, acoustic pressure elder generation from metal case 10 out, in upper cover, form altogether and ring, make sound more difficult add loud and clear.
It is emphasized that; the specific embodiment more than providing is only set forth the principle of work of the utility model for convenience; its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
