Description
Technical field
The present invention relates to a kind of audio playing apparatus, refer in particular to a kind of sound box player of effective minimizing standing wave.
Background technology
At present, sound box player, due to the restriction of design, can be subject to the interference of standing wave when playing sound.The principle of standing wave be when after sound sends by transfer of air to surrounding bar time, barrier meeting reflective sound wave, the sound wave of the reflected sound of the sound of some frequency just in time with the direction of vibration that source sound is identical, so the sound of this frequency will be reinforced, so the sound of this frequency will become large, also the reflected sound of some frequency just in time with the direction of vibration that source sound is contrary, so the sound of this frequency will weaken.In the full scale that the incorrect existence of sound box standing internal wave can make the audio amplifier sound pure intermediate frequency having influence on low frequency more or less full, the exquisiteness of high frequency.Therefore need to design a kind of sound box player that effectively can reduce standing wave.China Patent Publication No. CN2620956Y, publication date on June 16th, 2004, name is called in the utility model patent of " microporous wall integrated loudspeaker box " and discloses a kind of microporous wall integrated loudspeaker box, and comprise casing, casing is provided with loudspeaker, internal wiring terminal is connected with loudspeaker by connecting line, internal wiring terminal is connected with outer terminal by frequency divider, and the as a whole structure of casing, casing is distributed with micropore, box inside is provided with sound absorbing layer, and casing is also provided with phase-reversing tube.The audio amplifier that this utility model provides, owing to have employed monolithic construction, joint portion between each have employed the design of arc-shaped transition, without any seamed edge, corner angle in chamber, improve the rigidity of casing, built good acoustic enviroment, the micropore on casing serves again the effect of sound-absorbing and elimination standing wave preferably.But through facts have proved, the audio amplifier without seamed edge, corner angle is still limited in the effect eliminating standing wave, and the means depending the change of loudspeaker box structure alone are comparatively single.
Summary of the invention
The object of the invention is to overcome the defect that impact that sound box player in prior art is subject to standing wave causes performance to reduce, provide a kind of and change the sound box player that audio amplifier shape effectively reduces standing wave.
The object of the invention is to be achieved by following technical proposals:
A kind of sound box player of effective minimizing standing wave, comprise audio amplifier, audio amplifier comprises Loudspeaker front cover and audio amplifier bonnet, Loudspeaker front cover and audio amplifier bonnet form audio amplifier surface, two loudspeaker are provided with near protecgulum place, the irregular entirety that described audio amplifier surface is spliced for several polygon faceted pebbles in audio amplifier.The design of the comprehensive many faceted pebbles of this sound box player, because of the sound absorption of irregular faceted pebble, can make the scattering of sound wave generation multidirectional, and then reduces the bad reflection that each baffle forms unit sounding, thus alleviates the standing wave impact of sound reflection.
As a kind of preferred version, the faceted pebble angle between any two polygon faceted pebbles is all greater than 120 degree.The design being greater than 120 degree can make sound wave generation scattering better.
As a kind of preferred version, the angle between two loudspeaker is 150 degree of-170 degree.Two loudspeaker, not in same plane, make sound wave that multidirectional scattering easily occurs further, and then reduce the tonequality of raising in sound of standing wave generation, make the solidifying power taking of sound field better.
As a kind of preferred version, be provided with passive loudspeaker near bonnet place in audio amplifier, passive loudspeaker are fixed on passive horn bracket, and passive horn bracket is fixedly connected with bonnet, and passive loudspeaker are also electrically connected with the main circuit board in audio amplifier.Passive loudspeaker can improve the bass tonequality performance of machine, and passive loudspeaker are between main circuit board and bonnet, the space of itself and wiring board and the space to bonnet basically identical, produce best equal space and vibration when making loudspeaker vibrate dynamic, it is issuable to back pressure to offset again loudspeaker.
As a kind of preferred version, be provided with reticulate body outside loudspeaker, reticulate body is fixedly connected with described Loudspeaker front cover by bolt.The structure of reticulate body serves protection loudspeaker, the effect such as dust-proof.
As a kind of preferred version, be also provided with bluetooth module in audio amplifier, bluetooth module is connected with main circuit board.Bluetooth module can directly be connected with the equipment with Bluetooth function such as mobile phone or notebook computer, plays the audio frequency in these equipment.
As a kind of preferred version, be also provided with chargeable lithium cell in audio amplifier, lithium battery is connected with main circuit board.Built-in chargeable lithium cell person easy to use gos out and carries this audio amplifier, uses the long period when not needing civil power.
As a kind of preferred version, Loudspeaker front cover is also provided with two LED, a LED is for showing bluetooth module pairing service condition, and a LED is for showing lithium cell charging situation.
As a kind of preferred version, audio amplifier is provided with and adds and volume key three buttons for matching bluetooth, volume, and three buttons are provided with a meter point.Three buttons arrange 3 different rice point shapes respectively, and person easy to use directly touches just can learn it is which button, facilitate blind person or light bad when practicality, there is preferably visual effect simultaneously.
The invention has the beneficial effects as follows, sound box player is not in conplane design is effectively reduced the impact of standing wave on the sound wave that audio amplifier sends by audio amplifier surface polygon faceted pebble, two loudspeaker, and the design of passive loudspeaker simultaneously improves the bass tonequality performance of machine.And layout of the present invention is ingenious, be easy to realize, practical, cheap.
