Abstract
The utility model relates to a mid-high voice-frequency coaxial loudspeaker, which is formed by that a high voice-frequency loudspeaker unit which has uniform axle center and opposite magnetic pole with a middle voice-frequency loudspeaker unit is arranged in a staircase-shaped groove which is arranged at the middle of a lower leading pole plate for a T-shaped iron of the middle voice-frequency loudspeaker unit towards a pole core. The mediant sent out by the middle voice-frequency loudspeaker unit plays in the same axle and the same direction with the treble sent out by the high voice-frequency loudspeaker unit through a leading note hole on the T-shaped iron pole core with middle voice-frequency and a leading note pipe which is arranged on the lower leading pole plate of the T-shaped iron with middle voice-frequency. The utility model has the advantages of simple structure, compact structure, high sensitivity, accurate sound positioning, small distortion and good sound quality, and provides a novel loudspeaker which has good quality and is used for making a high-quality loudspeaker with various powers.
Description
The utility model relates to a kind of loud speaker, particularly alt frequency coaxial loudspeaker.
At present, sound intermediate frequency loud speaker and high audio loud speaker all are discrete on the market, are installed in that to take volume in the audio amplifier big, and structure is complicated, and because the range difference that two loud speakers are installed can produce certain distortion factor, influence auditory effect.
The purpose of this utility model provide a kind of with sound intermediate frequency unit and high audio unit be combined into one, compact conformation, volume are little, be suitable for the audio amplifier spouse, reduce the audio amplifier perforate, and it is clear that middle and high audio frequency is broadcast, highly sensitive, tonequality is good, the novel loud speaker that distortion is little.
The technical scheme that realizes above-mentioned purpose is: design a kind of alt coaxial loudspeaker frequently, it has by the sound intermediate frequency magnet, upward magnetic conduction pole plate, following magnetic conduction pole plate and pole piece are made the T iron of one, the sound intermediate frequency loudspeaker unit that intermediate frequency diaphragm voice coil loudspeaker voice coil constitutes and the high audio loudspeaker unit that is made of high audio magnet, magnetic conduction pole plate, high audio diaphragm voice coil loudspeaker voice coil.Its innovation main points are to offer step groove in the middle of the following magnetic conduction pole plate of the T iron of alt band loudspeaker unit in pole piece, high audio magnet and magnetic conduction pole plate thereof are installed in the groove under this step groove successively, and forming magnetic air gap between groove internal perisporium and high audio magnet and the magnetic conduction pole plate periphery wall down, high audio diaphragm voice coil loudspeaker voice coil is installed in the last groove of step groove by its support, and voice coil loudspeaker voice coil is positioned in the magnetic air gap, also uniformly on sound intermediate frequency T iron pole piece offer some axial middle pitch voice guide holes, the diaphragm voice coil loudspeaker voice coil outside of sound intermediate frequency loudspeaker unit is provided with protective cover, on the following magnetic conduction pole plate of T iron, be separately installed with sound intermediate frequency sound guide tube and high audio sound guide tube, and the high audio sound guide tube is positioned in the middle of the sound intermediate frequency sound guide tube.
Accompanying drawing is the utility model general structure schematic diagram.
The utility model is described in further detail below in conjunction with drawings and Examples.
The magnetic circuit system of sound intermediate frequency loudspeaker unit of the present utility model comprises the intermediate frequency magnet 12 that adopts Fe-B rare-earth permanent magnet to make, last magnetic conduction pole plate 10, following magnetic conduction pole plate 15 and pole piece 13 are made the T iron 11 of one, and by the magnetic air gap 6 that forms between last magnetic conduction pole plate 10 and the T iron pole piece 13; The diaphragm of sound intermediate frequency diaphragm, voice coil loudspeaker voice coil assembly 8 adopts ball teleblem sheet, is installed on the sound intermediate frequency on the magnetic conduction pole plate 10 by its support 7, and voice coil loudspeaker voice coil is positioned in the magnetic air gap 6; Be provided with protection aluminium cover 9 in described sound intermediate frequency ball teleblem sheet voice coil loudspeaker voice coil assembly outside.In pole piece 13, offer step groove in the middle of the following magnetic conduction pole plate 15 of T iron 11 in the above-mentioned sound intermediate frequency loudspeaker unit, the high frequency magnet 5 of high audio loudspeaker unit and last magnetic conduction pole plate 3 thereof just are installed in the following groove of step groove successively, reach formation magnetic air gap 4 between magnetic conduction pole plate 3 periphery walls at following groove internal perisporium and high frequency magnet 5, the diaphragm of high audio diaphragm voice coil loudspeaker voice coil assembly 1 adopts ball teleblem sheet, and be installed on by its support 16 in the last groove of step groove, its voice coil loudspeaker voice coil is positioned in the magnetic air gap 4.Also uniformly on the pole piece 13 of T iron 11 offer some axial middle pitch voice guide holes 14.On the following magnetic conduction pole plate 15 of T iron, be separately installed with flaring sound intermediate frequency sound guide tube 17 and high audio sound guide tube 18, and high audio sound guide tube 18 is positioned at the centre of sound intermediate frequency sound guide tube 17.Between the ball teleblem sheet of sound intermediate frequency, high audio ball teleblem sheet voice coil loudspeaker voice coil and magnetic conduction pole plate and be filled with some acoustical cottons 2 in the guard shield 9 respectively.
The utility model is simple in structure, compact.Frequency stable and continuous, its sound are desirable sphere waveforms, and sound is to accurate positioning, and be high, that middle pitch is broadcast is clear, highly sensitive, and distortion is little, and tonequality is good.A kind of high-quality loud speaker of novelty is provided for the senior audio amplifier of making high or low power.
