Abstract

The invention discloses a moving coil loudspeaker. A vibration system comprises a cone, a first locating support chip, a second locating support chip and an inner cone frame, wherein the outer edge of the first locating support chip is fixed on an outer cone frame; the inner edge of the first locating support chip is connected with a voice coil; the upper end of the inner cone frame is connected with the upper end of the outer cone frame through an outer yoke ring; the lower end of the inner cone frame is fixed on the first locating support chip; the second locating support chip is arranged above the first locating support chip; the inner edge of the second locating support chip is connected with the voice coil; the outer edge of the second locating support chip is fixed together with the inner cone frame, and the upper end of the cone is fixed at the upper end of the inner cone frame. The moving coil loudspeaker has the advantages that a voice coil cutting magnetic line inside a magnetic circuit system of the loudspeaker generates physical kinetic energy of an audio signal, the physical kinetic energy is transmitted to a diaphragm at the middle part through a voice coil skeleton, middle-frequency sound energy with a proper amplitude is generated, the connected inner cone frame is linked and acted by joint conduction of the second locating support chip (a middle-frequency support chip) and a first locating support chip (low-frequency support chip), so that low-frequency sound energy with a larger amplitude is generated.

Description

A kind of coil-moving speaker
Technical field
The present invention relates to a kind of loud speaker, especially relate to a kind of coil-moving speaker.
Background technology
Loud speaker is commonly called as loudspeaker, and its effect audio electrical signal is converted to acoustical signal and the sound of air medium radiation towards periphery.Loudspeaker are widely used in daily life, especially will use loudspeaker in sound box system, in some special individual or public place, require higher to the tonequality of loud speaker.Loud speaker can be divided into high pitch loudspeaker, Squawker and woofer by the classifying frequency range of its work.Traditional middle pitch or woofer can only intermediate frequency range or the performance of low frequency range more outstanding, more difficultly accomplish that both take into account.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of coil-moving speaker simultaneously taking into account intermediate frequency range and low frequency range
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of coil-moving speaker, comprise magnetic circuit assembly, voice coil loudspeaker voice coil, outer frame and vibrational system, it is characterized in that described vibrational system comprises cone, first locating branch slice, second locating branch slice and interior frame, the outward flange of the first described locating branch slice is fixed in outer frame, the inward flange of the first locating branch slice is connected with voice coil loudspeaker voice coil, described interior frame upper end is connected with outer frame upper end by outer yoke ring, interior frame lower end is fixed on the first locating branch slice, the second described locating branch slice is positioned at above the first locating branch slice, the second described locating branch slice is parallel to the first locating branch slice, the inward flange of the second locating branch slice is connected with voice coil loudspeaker voice coil, outward flange and the interior frame of the second locating branch slice are fixed, the upper end of described cone is fixed on interior frame upper end.
Described magnetic circuit assembly comprises T iron, magnet steel and train wheel bridge, and described magnet steel is arranged between T iron and train wheel bridge, and described voice coil loudspeaker voice coil inserts in the magnetic gap formed between T iron and train wheel bridge.
Described cone comprises vibrating diaphragm, interior yoke ring and the first external press edge, and described vibrating diaphragm lower end is connected to the upper end of voice coil loudspeaker voice coil, and the first described external press edge is fixed on the upper end upper surface of interior frame by the first press strip.
Described outer yoke ring comprises the second external press edge and interior flanging, described interior frame is provided with annular slotted, the second described external press edge is fixed on the upper end upper surface of outer frame by the second press strip, and through annular slotted inside outer yoke ring, the interior flanging on outer yoke ring is positioned at the upper end lower surface of outer frame.
Described outer frame is fixed by screws on train wheel bridge.
Be provided with dust cap in described cone, inside described T iron, Air Filter is set.
Compared with prior art, advantage of the present invention is the physical kinetic energy of the voice coil loudspeaker voice coil cutting magnetic line generation audio signal in this magnetic circuit of loudspeaker, conducts to the vibrating diaphragm being positioned at mid portion, produce the intermediate frequency acoustic energy of appropriate amplitude by speech coil framework; Conduction is combined simultaneously by the second locating branch slice (intermediate frequency props up sheet) and the first locating branch slice (low frequency props up sheet), interlock acts on the interior frame of connection, produce the low frequency acoustic energy compared with large amplitude, when therefore this loud speaker normally works, the audio power that low frequency/intermediate frequency is taken into account can be produced.
