Abstract
The utility model aims to provide a low frequency resonant loop full range loudspeaker system to raise the low frequency playback lower limit of a loudspeaker and improve the low frequency performance of the loudspeaker. The low frequency resonant loop full range loudspeaker system comprises a sound box and a loudspeaker formed by a basin stand, a diaphragm, a voice coil, and a magnetic component. The loudspeaker system is characterized in that the loudspeaker system also comprises a flexible resonant ring, and the loudspeaker is connected to the sound box through the resonant ring. When the resonant frequency is at a high frequency band, the flexible resonant ring does not generate resonance, only the diaphragm of the loudspeaker vibrates to push air, and middle and high frequency are replayed. When the frequency is lower than a loudspeaker F0 band, the flexible resonant ring generates resonance, the whole loudspeaker is driven to vibrate, low frequency is radiated, and thus the lower limit of the loudspeaker system playback lower frequency is enlarged. The low frequency resonant loop full range loudspeaker system has the advantages of simple structure, convenient assembly and good low frequency performance and is welcomed by the market.
Description
Technical field
The utility model belongs to electroacoustic techniques field, specially refers to the structure of speaker system.
Background technology
The principle of loud speaker is as follows: according to Fu Laiming Left Hand Rule, after the energising of the wire of voice coil loudspeaker voice coil, be subject to power and produce motion in magnetic field, voice coil loudspeaker voice coil drives vibrating diaphragm reciprocating, promotes air, to surrounding radiative acoustic wave.Existing loud speaker, particularly Microspeaker, because bore is less, all cannot take into account the playback of low frequency, and bass is restricted.
Utility model content
The purpose of this utility model is to propose a kind of low-frequency resonance ring full-range speaker system, to improve the low frequency playback lower limit of loud speaker, promotes its low frequency performance.
The loudspeaker that low-frequency resonance ring full-range speaker of the present utility model comprises audio amplifier and is made up of basin frame, vibrating diaphragm, voice coil loudspeaker voice coil, magnet assembly, key is that this speaker system also comprises a flexible resonant ring, described loudspeaker are connected with audio amplifier by resonant ring.
At the resonance frequency of loud speaker, to high band, this flexibility resonant ring does not produce resonance, only promotes air, playback medium-high frequency by the vibrating diaphragm vibration of loudspeaker; And in frequency the frequency range lower than loud speaker F0, flexible resonant ring produces resonance, drives whole loudspeaker vibration, radiation low frequency, thereby expanded the lower limit of speaker system playback low frequency.
Further, described resonant ring has one or more of flangings, to improve the low-frequency resonant performance of flexible resonant ring.
Further, the bellmouth orifice lateral surface of the medial surface of the periphery of resonant ring and audio amplifier is pasted fixing, the central lateral surface of resonant ring and basin frame periphery medial surface are pasted fixing, like this in fixing loudspeaker, can avoid occurring gap between audio amplifier and loudspeaker and damage tonequality, and when audio amplifier horizontal (be loudspeaker upward), resonant ring can provide good supporting role for loudspeaker, himself low-frequency resonant performance of perfect performance simultaneously.
That low-frequency resonance ring full-range speaker of the present utility model has advantages of is simple in structure, easy to assembly, low frequency performance is good, is deeply subject to the welcome in market.
Brief description of the drawings
Fig. 1 is the structural representation of low-frequency resonance ring full-range speaker system of the present utility model.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is described in further detail as effect and the operation principle etc. of the mutual alignment between the shape of related each member, structure, each several part and annexation, each several part.
Embodiment 1:
As shown in Figure 1, the low-frequency resonance ring full-range speaker system of the present embodiment comprises audio amplifier 1 and by basin frame 2, vibrating diaphragm 3, voice coil loudspeaker voice coil 4, the loudspeaker that magnet assembly 5 forms, key is that this speaker system also comprises a circular resonant ring 6 of flexibility, the bellmouth orifice lateral surface of the medial surface of the periphery of resonant ring 6 and audio amplifier 1 is pasted fixing, the central lateral surface of resonant ring 6 and basin frame 2 periphery medial surfaces are pasted fixing, thereby loudspeaker are connected with audio amplifier 1 by resonant ring 6, like this in fixing loudspeaker, can avoid occurring gap between audio amplifier 1 and loudspeaker and damage tonequality, and when audio amplifier horizontal (be loudspeaker upward), resonant ring 6 can provide good supporting role for loudspeaker, the perfect low-frequency resonant performance of bringing into play himself simultaneously.
Resonant ring 6 has a circular flanging, to improve the low-frequency resonant performance of flexible resonant ring 6.
At the resonance frequency of loud speaker, to high band, this flexibility resonant ring 6 does not produce resonance, only vibrates promotion air by the vibrating diaphragm 3 of loudspeaker, playback medium-high frequency; And in frequency the frequency range lower than loud speaker F0, flexible resonant ring 6 produces resonance, drive whole loudspeaker vibration, radiation low frequency, play the effect of passive radiator, thereby expanded the lower limit of speaker system playback low frequency, through test, the small diameter loudspeaker of the diameter 50mm of the present embodiment, its low frequency playback lower limit can reach 80Hz.
Claims (3)
1. a low-frequency resonance ring full-range speaker system, the loudspeaker that comprise audio amplifier and be made up of basin frame, vibrating diaphragm, voice coil loudspeaker voice coil, magnet assembly, is characterized in that this speaker system also comprises a flexible resonant ring, described loudspeaker are connected with audio amplifier by resonant ring.
2. low-frequency resonance ring full-range speaker system according to claim 1, is characterized in that described resonant ring has one or more of flangings.
