Abstract
The utility model discloses a moving-coil loudspeaker. A vibration system comprises a paper 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, and 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, and the lower end of the inner cone frame is fixed on the second locating support chip; the second locating support chip is located above the first locating support chip; the inner edge of the second locating support chip is connected with the voice coil, and the outer edge of the second locating support chip is fixed together with the inner cone frame; and the upper end of the paper cone is fixed on the upper end of the inner cone frame. The moving-coil loudspeaker has the advantages that the voice coil arranged in a magnetic circuit system of the loudspeaker cuts a magnetic line to generate physical kinetic energy of an audio signal, the physical kinetic energy is conducted to a vibrating diaphragm located in a middle part through a voice coil framework to generate medium frequency sound energy with a proper amplitude; and meanwhile, the second locating support chip (a medium frequency support chip) and the first locating support coil (a low frequency support chip) are united to conduct and linked to act on the connected inner cone frame, so that low frequency sound energy with a higher amplitude is generated.
Description
Technical field
The utility model relates to a kind of loud speaker, especially relates 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.

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, 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, the utility model has the advantages that the voice coil loudspeaker voice coil cutting magnetic line in this magnetic circuit of loudspeaker produces the physical kinetic energy of audio signal, conduct to the vibrating diaphragm that is positioned at mid portion by speech coil framework, produce 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.
