Abstract
The utility model relates to an antimagnetic loudspeaker, which is composed of a speaker frame, magnet steels, a magnetism conducting board, a pole shoe, a centering supporting sheet and magnetism conducting screws. The utility model is characterized in that a double-magnetism structure is composed of at least two magnet steels which are stacked mutually, the magnetism conducting board, the magnetism conducting screws and the pole shoe, which performs effectively a magnetic shield function, reduces the Q value, raises the sensitivity and ensures the tone quality of the utility model.
Description
The utility model belongs to a kind of antimagnetic type loud speaker.
In order to improve the tonequality of loud speaker, especially bore the tonequality of benzvalene form loud speaker, people have proposed various schemes: for example, " moving-coil type signal feedback loud speaker " (application number is 89213174.8) proposed the scheme that a voice coil loudspeaker voice coil is provided with the signal feedback coil, " double-winding voice-coil speaker and function discharge road thereof " (application number is 86107860) discloses a kind of improved electroacoustic device, the loud speaker of this device has two voice coil loudspeaker voice coil windings, and power amplifier is the direct-coupled circuit of the two-way output of balance.These schemes are improved by voice coil loudspeaker voice coil or circuit to loud speaker, and in the hope of raising loud speaker tonequality, but these schemes have all been ignored the influence of magnetic field to loud speaker tonequality, thereby have suppressed the effect of tone quality improving.
The purpose of this utility model provides a kind of have excellent magnetic structure, antimagnetic type loud speaker, utilizes the worn-out effect of magnetic cup, improves the tonequality of loud speaker.
The utility model by basin frame, magnet steel, magnetic conductive board, pole shoe, voice coil loudspeaker voice coil, decide that core props up sheet, the magnetic conduction screw constitutes.Select two or more than two magnet steel and magnetic conductive board for use."
" inside of shape pole shoe, placing the magnet steel of annular, the contact-making surface of pole shoe and magnet steel sticks with glue tightly, is placing the magnetic conductive board of centre perforate above the magnet steel, successively magnet steel, magnetic conductive board layering are stacked by this, and contact-making surface all sticks with glue tightly.From uppermost magnetic conductive board interstitial hole, penetrate the magnetic conduction screw, be connected with the pole shoe of bottom.Pole shoe is by the bottom of screw at the basin frame.
The utility model can effectively play magnetic screening action owing to adopt two magnetic structures, reduces the Q value, improves sensitivity, thereby has guaranteed the tonequality of loud speaker.
Accompanying drawing is that the utility model cuts open and shows structural representation.
Now further specify in conjunction with the accompanying drawings: the utility model is by basin frame (1), magnet steel (4,6), magnetic conductive board (5,7), pole shoe (3), voice coil loudspeaker voice coil (10), decide core and prop up sheet (12), magnetic conduction screw (8) and constitute magnet steel (4,6), magnetic conductive board (5,7) is respectively selected two or more than two for use."
" shape pole shoe (3) inside; placing the magnet steel (4) of annular; the contact-making surface of pole shoe (3) and magnet steel (4) sticks with glue tightly; the magnetic conductive board (5) of perforate in the middle of placing above the magnet steel (4); press this successively with magnet steel (6); magnetic conductive board (7) layering stacks, and contact-making surface sticks with glue tightly, from uppermost magnetic conductive board (7) interstitial hole, penetrate magnetic conduction screw (8), be connected with the pole shoe (3) of bottom, pole shoe (3) is fixed on the bottom of basin frame (1) by screw (2), voice coil loudspeaker voice coil (10) is placed in the gap (9) of pole shoe (3) and magnetic conductive board (5) formation, glued joint with vibrating basin (11) voice coil loudspeaker voice coil (10) upper end, the middle part by decide core and prop up sheet (12) and basin frame (1) fixedly connected, decide core and prop up sheet (12) and can select two for use.
Claims (3)
1, a kind of by magnet steel, magnetic conductive board, pole shoe, basin frame, magnetic conduction screw, voice coil loudspeaker voice coil, decide core and prop up the loud speaker that sheet constitutes, it is characterized in that "
" shape pole shoe (3) inside; placing magnet steel (4); pole shoe (3) and magnet steel (4) contact-making surface cling each other; above the magnet steel (4); magnetic conductive board (5), magnet steel (6), the magnetic conductive board (7) of perforate in the middle of stacking successively; magnetic conduction screw (8) penetrates from the magnetic conductive board (7) at top, is connected with pole shoe (3).
2, loud speaker according to claim 1 is characterized in that magnet steel (4,6), magnetic conductive board (5,7) respectively select two or more than two for use.
3, loud speaker according to claim 1 is characterized in that deciding core and props up sheet (12) and select two for use.
