Abstract
The utility model discloses a resonance phase-reversing sound box which comprises a box body and a loudspeaker installed on the box body, as well as a phase-reversing tube installed on the box body and a tuning cavity in front of the phase-reversing tube. In the utility model, a single working mode of the traditional phase-reversing sound box is broken through, air in the cavity in the front is pushed through air movement in the phase-reversing box to generate resonance low frequency and radiate towards the outside through an opening so as to achieve the purposes of improving low frequency volume and strength and promoting the low-frequency transient responsiveness.
Description
Technical field
The utility model relates to audio amplifier, and particularly playback is than a kind of resonant mode reflex cabinet of low-frequency sound effect.
Background technology
Phase inverted cabinet claims bass reflex formula audio amplifier again, as shown in Figure 1, traditional phase inverted cabinet is made up of the casing of a loudspeaker unit and a band phase-reversing tube, when loudspeaker unit is worked, the sound wave that loud speaker gives off behind is radiated the place ahead through 180 degree of phase place adjustment behind the phase-reversing tube, superimposed with the sound wave of loud speaker front, then jointly to previous irradiation, low-frequency effect is strengthened.
Summary of the invention
The purpose of this utility model is to improve low frequency amount sense and dynamics, improves the resonance phase inverted cabinet of low frequency transient response.
For achieving the above object, the utility model adopts following technical scheme:
A kind of resonance phase inverted cabinet comprises casing and is installed in loud speaker on the casing, it is characterized in that, also comprises the phase-reversing tube that is installed on the casing and the resonant cavity in phase-reversing tube exit.
Its beneficial effect of the utility model is, the single mode of operation of the phase inverted cabinet that breaks traditions, motion by the paraphase air in tube promotes air in the cavity of front, produce resonance low frequency and by opening to external radiation, to reach amount sense and the dynamics that promotes low frequency, improve low frequency transient response ability.
Description of drawings
Fig. 1 is the mounting structure schematic diagram of prior art phase inverted cabinet;
Fig. 2 is the generalized section of the utility model resonance phase inverted cabinet.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 2, during work, the loudspeaker unit motion promotes the air in the casing, and airborne molecule moves back and forth as spring, promotes the air movement in the phase-reversing tube simultaneously, and the sound wave phase place in the casing has been adjusted 180 degree.Phase-reversing tube openend and resonant cavity link, therefore promote the air movement of resonant cavity again, air molecule repeatedly reflects and produces in resonant cavity at cavity inner wall and resonates, and the resonance sound wave is strengthened the intensity of acoustic wave in the far super phase-reversing tube of intensity greatly because of repeatedly reflecting intensity.Resonant cavity has an opening to communicate with the external world, and the resonance sound wave in the chamber is by the outside radiative acoustic wave of opening, and is superimposed to extraradial sound wave with loudspeaker unit.Low frequency amount sense after the stack is more sufficient, and dynamics is stronger, makes the LF-response of audio amplifier obtain very big reinforcement.The big I of adjusting the volume resonant cavity opening of resonant cavity respectively obtains different LF-response.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, allly does fixed any modification within spirit of the present utility model and principle, is equal to and replaces and improvement etc., all should be included within the utility model protection range.
