Abstract
The utility model provides a speaker magnetic structure of double gap, the magnetic conduction yoke constituted two endocentric loop type clearance magnetic circuits in adopted the outer magnetic conduction yoke of U type, magnet and T type: bond magnetic conduction yoke in the outer magnetic conduction yoke of U type, the T type on magnet respectively, form two inside and outside even loop type clearances, the fixed good magnet structure that will bond makes two rings type clearance have even magnetic field intensity through the magnetization of outside magnet charger. Wherein interior loop type clearance is used for making up the vibration system that the high frequency was reset, and outer loop type clearance is used for making up the vibration system that the low frequency was reset to widen the frequency response range of speaker.
Description
Technical field
The utility model relates to a kind of magnetic circuit structure for loudspeaker of double gap, especially the magnetic structure of double gap can build two groups of vibrational systems respectively, be respectively used to playback high and low frequency, thus widen the frequency response range of loud speaker, and be conducive to the vanning volume reducing loud speaker.
Background technology
At present, conventional loudspeakers adopts two kinds of common magnetic structures mostly, and one is outer magnetic structure: form an annular gap magnetic circuit by upper conduction magnetic board, magnet and T-shaped lower magnetic conductive board.Another kind is inner magnetic structure: form an annular gap magnetic circuit by magnetic conductive board, magnet and U-shaped yoke.The loud speaker of these two kinds of structures all only has an annular gap magnetic circuit, adopt the frequency response of loudspeaker scope of an annular gap magnetic structure narrow, often need to use the loud speaker of two or more different frequency response range to set up audio amplifier, desirable frequency response could be obtained.Especially, under narrow and small installation environment, single loud speaker is difficult to obtain good frequency response.
Summary of the invention
In order to overcome the shortcoming of existing conventional loudspeakers magnetic structure, the purpose of this utility model is the magnetic circuit structure for loudspeaker designing a kind of double gap, form two concentric annular gap magnetic circuits by U-shaped outer magnetic conduction heel piece, magnet and T-shaped interior magnetic conduction heel piece, one of them outer annular gap magnetic circuit is for building the vibrational system of low frequency reproduction; The vibrational system that another inner ring type gap magnetic circuit is reset for building high frequency.
The beneficial effects of the utility model are, only employing one piece is U-shaped leads outer yoke iron, one block of magnet, and one piece of T-shaped interior magnetic conduction heel piece just can build two annular gap.Owing to adopting double gap magnetic structure, can build two vibrational systems, one of them is for the playback of low frequency, and another vibrational system is used for the playback of high frequency, thus has widened the frequency response range of loud speaker.
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Accompanying drawing explanation
Fig. 1 is the magnetic circuit structure for loudspeaker figure of double gap.
Fig. 2 is double gap magnetic structure magnetizing direction figure.
1. magnet in figure, the outer magnetic conduction heel piece of 2.U type, magnetic conduction heel piece in 3.T type, 4. inner ring type gap, 5. outer annular gap.
Embodiment
In FIG, respectively U-shaped outer magnetic conduction heel piece 2, T-shaped interior magnetic conduction heel piece 3 are bonded on magnet 1, form inside and outside two uniform annular gap; Wherein inner ring type gap 4 is for building the vibrational system of high frequency playback, and outer annular gap 5 is for building the vibrational system of low frequency reproduction.
In fig. 2, the magnet structure in the Fig. 1 be adhesively fixed is magnetized by outside magnet charger, form two uniform annular gap magnetic fields.
Claims (1)
1. the magnetic circuit structure for loudspeaker of a double gap, it is characterized in that the annular gap magnetic circuit adopting U-shaped outer magnetic conduction heel piece (2), magnet (1) and T-shaped interior magnetic conduction heel piece (3) formation two concentric: be bonded on magnet (1) by U-shaped outer magnetic conduction heel piece (2), T-shaped interior magnetic conduction heel piece (3) respectively, form inner ring type gap (4) and outer annular gap (5); The magnet structure be adhesively fixed is magnetized by outside magnet charger, makes two annular gap have uniform magnetic field intensity, after installation, constitute the magnetic circuit structure for loudspeaker of double gap of the present utility model.
