Description
Technical field
The utility model is related to audio amplifier field, more particularly to a kind of big volume ultra-long time of small size plays water-proof speaker.
Background technology
Audio amplifier is the terminal of whole sound system, and its effect is that audio electric energy is converted into corresponding acoustic energy, and its spoke
Space is mapped to go.
It is the extremely important part of sound system, because it is responsible for is transformed into acoustical signal for people's electric signal
Ear directly listens to so one mission critical, and the sense of hearing that it will be directly with people is come into contacts with, and the sense of hearing of people be it is very sensitive,
And there is very strong resolving ability to the tone color of complex sound.
Because human ear exactly evaluates the subjective feeling of sound the most important standard of a sound system tonequality quality, because
This, it is believed that the performance height of audio amplifier is to play key effect to the playing quality of a sound system.
The physical model of audio amplifier is that a hole is opened on one block of infinitely great rigid baffle, installs loudspeaker, thus can
Loop will not be formed by ensureing the voice signal of loudspeaker obverse and reverse, cause sound wave loop.
But in actually used, audio amplifier can not possibly make infinity, therefore, and people are formed behind loudspeaker with baffle
One closed space, it is ensured that the front transmission of sound wave.
Following the problem of：The problem of after audio amplifier is closed due to atmospheric pressure, the casing of audio amplifier is more big more is conducive to low
Frequency sound-reducing, so, the volume of general audio amplifier is that the speaker size of the bass unit in calculates a compromise
Data.
Much it can still be not allow for too big casing by environment, people are in order to further reduce volume, and according to sound wave
The requirement that feature and reinforcement low-frequency sound wave are reset devises baffle in case, phase-reversing tube, resonant cavity etc., primarily in low frequency frequently
Section strengthens the voice signal of certain wavelength, and further reduces influence of the atmospheric pressure to sound-reducing.Existing audio amplifier
It is short using the working time mainly using audio, and the larger unsuitable carrying of audio amplifier volume is distinguished on multiple loudspeakers, and shell
It is larger potential safety hazard not prevent fires non-watertight.
