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
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 is to convert audio electrical signal to acoustical signal and towards periphery air medium radiation sound.Loudspeaker are widely used in the daily life, especially will use loudspeaker in sound box system, and are in some special individual or public place, higher to the tonequality requirement of loud speaker.Loud speaker can be divided into high pitch loudspeaker, Squawker and woofer by the frequency range classification of its work.Traditional middle pitch or woofer can only be more outstanding at intermediate frequency range or the performance of low frequency range, and difficulty accomplishes that both take into account.
Summary of the invention
Technical problem to be solved by this invention provides a kind of coil-moving speaker that can take into account simultaneously intermediate frequency range and low frequency range
The present invention solves the problems of the technologies described above the technical scheme that adopts: a kind of coil-moving speaker, comprise the magnetic circuit assembly, voice coil loudspeaker voice coil, outer basin frame and vibrational system, it is characterized in that described vibrational system comprises cone, the first locating branch slice, the second locating branch slice and interior basin frame, the outward flange of described the first locating branch slice is fixed on the outer basin frame, the inward flange of the first locating branch slice is connected with voice coil loudspeaker voice coil, described interior basin frame upper end is connected with outer basin frame upper end by outer yoke ring, interior basin frame lower end is fixed on the first locating branch slice, described the second locating branch slice is positioned at the first locating branch slice top, described the second 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, the outward flange of the second locating branch slice and interior basin frame are fixed, and the upper end of described cone is fixed on interior basin 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 the train wheel bridge, and described voice coil loudspeaker voice coil inserts in the magnetic gap that forms between T iron and the 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 described the first external press edge is fixed on the upper end upper surface of interior basin frame by the first press strip.
Described outer yoke ring comprises the second external press edge and interior flanging, described interior basin sets up and is equipped with annular slotted, described the second external press edge is fixed on the upper end upper surface of outer basin frame by the second press strip, and annular slotted is passed in outer yoke ring inboard, and the interior flanging on the outer yoke ring is positioned at the upper end lower surface of outer basin frame.
Described outer basin frame is fixed by screws on the train wheel bridge.
Be provided with dust cap in the described cone, described T iron inboard arranges Air Filter.
Compared with prior art, advantage of the present invention is the physical kinetic energy that the voice coil loudspeaker voice coil cutting magnetic line in this magnetic circuit of loudspeaker produces audio signal, conducts to the vibrating diaphragm that is positioned at mid portion by speech coil framework, produces the intermediate frequency acoustic energy of suitable amplitude; The simultaneously conduction of uniting 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 basin frame of connection, generation is than the low frequency acoustic energy of large amplitude, so during this loud speaker normal operation, can produce the audio power that low frequency/intermediate frequency is taken into account.
