Abstract
The utility model discloses a dual-drive thin speaker, which comprises magnetic circuit systems, voice coils, a cone frame, spiders, a diaphragm and a corrugated rim, wherein the voice coils are arranged in the magnetic clearances of the magnetic circuit systems; the upper ends of the voice coils pass through the cone frame and the diaphragm and are fixed on the diaphragm; the diaphragm is fixed on the cone frame through the corrugated rim; two sets of the magnetic circuit systems, the voice coils and the spiders of the speaker are arranged; two through holes for installing the voice coils are symmetrically arranged at two sides of the centre of the cone frame; two centrosymmetric installation holes for fixedly installing the spiders are also arranged outside the through holes of the cone frame; the diaphragm is respectively provided with downward concave surfaces corresponding to the two spiders; and the bottoms of the concave surfaces are fixedly connected with the centres of the spiders. According to the utility model, by adopting the structure that the two spiders are combined with the two downward concave surfaces of the diaphragm, the thickness of the speaker is reduced; furthermore, the resonant frequency is low; furthermore, due to the dual-drive structure composed of the two sets of magnetic circuit systems and the two voice coils, higher power of the speaker while having small volume and thinner thickness can be realized.
Description
Technical field
The utility model relates to the loudspeaker techniques field, refers to especially a kind of pair of driving thin speaker.
Background technology
Along with the progress of demand and the electronic technology in market, various electronic products are all towards thinner smaller and more exquisite future development, and are also more and more higher to the requirement of quality simultaneously; Loud speaker is majority with the accessory of the electronic product indispensability of audio frequency output, therefore need to accomplish equally thinner smaller and more exquisite and better acoustical quality.Traditional loud speaker is substantially by several parts formations such as magnetic circuit system (magnet, U iron T iron, washer), vibrational system (vibrating diaphragm, voice coil loudspeaker voice coil), support auxiliary system (playing ripple, basin frame, ring) and dust caps, wherein the vibrating diaphragm of vibrational system is the acoustic radiating device of loud speaker, determining the sound reproduction performance of loud speaker in sizable degree, traditional vibrating diaphragm is conical, and the loud speaker integral thickness of this structure is higher; If need larger power and bass effect preferably, then diaphragm diameter must be done very greatly; Market is in the urgent need to improving loadspeaker structure, makes it thinner, more powerful, tonequality is better.
The utility model content
The utility model provides a kind of pair of driving thin speaker for the thicker larger defective of existing loud speaker volume, this loud speaker very thin thickness, and power is large, bass effect is better.
For achieving the above object, the technical solution adopted in the utility model is: a kind of pair of driving thin speaker, comprise magnetic circuit system, voice coil loudspeaker voice coil, basin frame, play ripple, vibrating diaphragm and ring, wherein, voice coil loudspeaker voice coil is located in the magnetic gap of magnetic circuit system, the upper end of this voice coil loudspeaker voice coil is passed basin frame and vibrating diaphragm and is fixed on the vibrating diaphragm, and vibrating diaphragm is fixed on the basin frame by ring; The described magnetic circuit system of this loud speaker, described voice coil loudspeaker voice coil and described bullet ripple are equipped with two groups, be provided with to the center bilateral symmetry of described basin frame two through holes that are used for installing voice coil loudspeaker voice coil, and the through hole of this basin frame outside also is provided with two installing holes that are used for being fixedly mounted with the bullet ripple that are centrosymmetric, corresponding two positions that play ripple of described vibrating diaphragm are respectively equipped with downward concave face, and the bottom of this concave face is affixed with the center that plays ripple.
Described magnetic circuit system of the present utility model is inner magnetic structure, comprises successively affixed U iron, the first magnet and the first washer, and wherein the U ferropexy is in the described through hole of described basin frame.
Described magnetic circuit system of the present utility model is outer magnetic structure, comprises successively affixed T iron, the second magnet and the second washer, and wherein the second washer is fixed in the described through hole of described basin frame.
Of the present utility model on described vibrating diaphragm the position of corresponding two described voice coil loudspeaker voice coils respectively be provided with a dust cap.
The edge of described vibrating diaphragm of the present utility model is the semi arch rectangle.
The beneficial effects of the utility model are: two described bullet ripples are symmetricly set in the both sides at basin frame center, corresponding vibrating diaphragm is arranged to two downward concave faces, compare traditional conical diaphragm and play the structure that ripple is arranged at the vibrating diaphragm center, not only greatly reduced the thickness of loud speaker, and two play ripple so that the amplitude of vibrating diaphragm reduces, and the air-flow of front is little during vibration, makes little amplitude can make low resonance frequency, and vibrate more balance, bass effect is better; And two groups of magnetic circuit systems and two two Drive Structure that voice coil loudspeaker voice coil forms can make loud speaker in the situation that small size and accomplish more high-power than minimal thickness.
