Abstract
The utility model relates to an electric tweeter, comprising a horn, a ring magnet, a voice coil and a diaphragm. A magnetic conduction pole is arranged in the center of the magnet, and the bottom of the magnetic conduction pole is connected with the bottom of the magnet. A ring magnetic conduction plate is arranged on the upper part of the magnet, and the upper part of the magnetic conduction plate is fixedly connected with a voice coil suspension. The horn is arranged on the voice coil suspension, and the diaphragm is arranged between the horn and the voice coil suspension. A bobbin is arranged between the magnetic conduction plate and the magnetic conduction pole, and the upper end of the bobbin is fixedly connected with the diaphragm. The voice coil is wound around the bobbin. The utility model has the beneficial effects of reasonable structure, good effect, long service life and material saving.
Description
Technical field
The utility model relates to a kind of public address set, especially a kind of electronic high pitch loudspeaker.
Background technology
Present used electrodynamic loudspeaker unreasonable structure, use makes trouble.And its cost height, weak effect, service time is not long, and the wasting of resources is big.
The utility model content
The utility model will solve the defective of above-mentioned prior art, and a kind of electronic high pitch loudspeaker rational in infrastructure is provided.
The utility model solves the technical scheme that its technical problem adopts.This electronic high pitch loudspeaker comprises horn, annular magnet, voice coil loudspeaker voice coil, vibrating diaphragm, is equipped with conducting magnetic column in the middle of this magnet, and this conducting magnetic column bottom is connected with the magnet bottom; Magnet top is equipped with the ring-type magnetic conductive board, and this magnetic conductive board top is connected with voice coil suspension, and horn is located on the voice coil suspension, and vibrating diaphragm is located between horn and voice coil suspension; Be equipped with bobbin between magnetic conductive board and conducting magnetic column, this bobbin upper end is affixed with vibrating diaphragm; Voice coil loudspeaker voice coil is around on this bobbin.
The effect that the utility model is useful is: the utility model is rational in infrastructure, and is effective, and service time is long, saves material.
Description of drawings
Fig. 1 is that the utility model partly cuts open structural representation;
Description of reference numerals: conducting magnetic column 1, magnet 2, voice coil suspension 3, magnetic conductive board 4, voice coil loudspeaker voice coil 5, vibrating diaphragm 6, throat taps 7, horn 8, bobbin 9, bolt 10.
Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described further:
This electronic high pitch loudspeaker comprises horn 8, annular magnet 2, voice coil loudspeaker voice coil 5, vibrating diaphragm 6, is equipped with conducting magnetic column 1 in the middle of this magnet 2, and this conducting magnetic column 1 bottom is connected with magnet 2 bottoms; Magnet 2 tops are equipped with ring-type magnetic conductive board 4, and these magnetic conductive board 4 tops are connected with voice coil suspension 3, and horn 8 is located on the voice coil suspension 3, and vibrating diaphragm 6 is located at 3 of horn 8 and voice coil suspensions, vibrating diaphragm 6 undulates.1 of magnetic conductive board 4 and conducting magnetic column are equipped with bobbin 9, and these bobbin 9 upper ends and vibrating diaphragm 6 are affixed; Voice coil loudspeaker voice coil 5 is around on this bobbin 9.Be provided with throat taps 7 in the horn 8, this throat taps 7 is positioned at vibrating diaphragm 6 tops, and is fixed in conducting magnetic column 1 by bolt 10.Horn 8 is made of plastics with throat taps 7.
Magnet 2 is bonding by magnetic conductive board 4 and conducting magnetic column 1 bottom, constitutes magnetic loop.Voice coil loudspeaker voice coil 5 is put in the magnetic gap of magnetic conductive board 4 and conducting magnetic column 1 formation.When voice-frequency signalling current passes through loudspeaker voice coil, voice coil loudspeaker voice coil 5 produces alternating magnetic field in magnetic gap, the magnetic field interaction of this alternating magnetic field and permanent magnet, force voice coil loudspeaker voice coil 5 vibrations, the vibrating diaphragm 6 that driving and voice coil loudspeaker voice coil 5 are pasted together vibrates in air medium and sounds, realize the function of electroacoustic conversion, the Oscillation Amplitude of vibrating diaphragm is directly proportional with input tone currents size and is relevant with the voice frequency of input.
