Description
Technical field
The utility model relates to the audio amplifier field, relates in particular to a kind of mobile phone pedestal audio amplifier player.
Background technology
The pedestal audio amplifier of existing smart mobile phone is when music playing, and smart mobile phone is transferred to the pedestal audio amplifier by its mobile phone connecting interface with audio analog signals, and the pedestal audio amplifier amplifies signal, plays out music by loudspeaker.Make because the shell of the pedestal audio amplifier of existing smart mobile phone generally all is the rectangular plate of rule, and be to be arranged in parallel between two loudspeaker, can produce larger standing wave when music playing, standing wave is large will affect the music effect of pedestal audio amplifier.
China Patent Publication No. CN202435554U, open day is on September 12nd, 2012, name is called in the scheme of " a kind of audio amplifier player " and discloses a kind of audio amplifier player, comprise the fragrant piece of plastic casing, expansion chamber, speaker body and solid, be provided with an expansion chamber that can suck and get rid of gas in the plastic casing, be provided with loudspeaker in the expansion chamber, be provided with the fragrant piece of solid in the loudspeaker.Weak point is, this audio amplifier player can not use as the pedestal audio amplifier of existing smart mobile phone, and acoustical quality is not good.
The utility model content
The utility model is can not to use as the pedestal audio amplifier of existing smart mobile phone in order to solve existing audio amplifier player, and acoustical quality is not good, and the pedestal audio amplifier of existing smart mobile phone standing wave when music playing is larger, affect these deficiencies of the music effect of pedestal audio amplifier, a kind of standing wave that can eliminate in a large number the pedestal audio amplifier is provided, and the music effect is a kind of mobile phone pedestal audio amplifier player preferably.
To achieve these goals, the utility model is by the following technical solutions:
A kind of mobile phone pedestal audio amplifier player, comprise: two loudspeaker, top cover, lower cover, it is characterized in that, top cover and lower cover are the faceted pebble of sealene triangle, and the angle between per two faceted pebbles is all more than 145 degree, the top cover upper end is provided with groove, top cover upper end in the groove front side is provided with two bellmouth orifices, described two loudspeaker are screwed respectively up and are installed in two bellmouth orifices, and the angle between two loudspeaker is less than 15 degree, and described lower cover is screwed the lower end that is connected to top cover.
Eliminate standing wave from surperficial many faceted pebbles of pedestal casing of loudspeaker box as far as possible.Theoretically, many faceted pebbles are to eliminating standing wave, and many faceted pebbles can reduce each baffle to the impact of the bad reflection, particularly standing wave of unit sounding formation.The design of the comprehensive many faceted pebbles of this programme, such faceted pebble design can be down to minimum with the each side baffle area of audio amplifier, thereby reaches the effect that improves pedestal audio amplifier tonequality.The faceted pebble of the irregular contour of this programme all more than 145 degree, because of the sound absorption of irregular faceted pebble, can make the scattering of Sonic wave sending multidirectional, thereby alleviates the standing wave impact of sound reflection, and then promotes the tonequality result of broadcast of pedestal audio amplifier.
Consider that from ranking and the angle of loudspeaker source of sound the fire-fighting standing wave is to improve the tonequality performance.In the audio amplifier room of KTV or home theater etc., audio amplifier is all according to Principles of Acoustics arranging at an angle, by contrasting two groups of data, find that the loudspeaker of non-angular symmetry arrangement are not as good as the covibration of standing wave in the space, as long as the distance of the parallel metope of two opposition equals the integral multiple of half-wavelength, resonance will occur, produce standing wave.If the standing wave that three groups of parallel metopes produce respectively in the space has frequency overlap, will form stronger standing wave, therefore tackle another way of standing wave and reduce standing wave with audio amplifier pendulum position exactly.Angle between two loudspeaker of this programme is less than the angle of 15 degree arranges, and two loudspeaker are less than an inside gradient about 15 degree with respect to casing, to eliminate the tonequality of raising in the sound, makes the solidifying power taking of pedestal audio amplifier sound field better.
As preferably, also comprise mobile phone connecting interface, micro-control unit, power amplifier, described mobile phone connecting interface is connected with micro-control unit, and described mobile phone connecting interface, described loudspeaker all are connected with described power amplifier, and described micro-control unit is controlled power amplifier.With micro-control unit power amplifier is finely tuned, thereby the standing wave that reduces the pedestal audio amplifier affects, and promotes the tonequality result of broadcast of pedestal audio amplifier.
As preferably, the top cover of the center between two bellmouth orifices is provided with the mouth of pipe, is fixedly connected with phase-reversing tube at the mouth of pipe.The antiphase sound wave of the inside radiation of pedestal audio amplifier, casing effect through the pedestal audio amplifier, again when swinging to pipe to external radiation, wherein the sound wave of some lower frequency limit can approach with the same frequency sound wave phase place of surface radiation before the casing of pedestal audio amplifier, then the radiation efficiency of loudspeaker be improved, thereby expanded LF-response, also reduced the impact of standing wave, when the bass supercharging, bass can be cleaner, and the acoustical quality that the pedestal audio amplifier is play is better.
As preferably, the top cover above two loudspeaker is installed with the iron net.The iron net not only plays the effect of protection loudspeaker, and also because of network structure, the standing wave of generation is almost nil, so that the pedestal audio amplifier is not only solid and reliable, and acoustical quality is better.
As preferably, be pasted with the foam vibration-damping sheet in recess sidewall.The foam vibration-damping sheet not only is easy to mobile phone chucking is placed in the groove, and is safe and reliable so that the pedestal audio amplifier not only is easy to use so that the foam vibration-damping sheet is difficult for producing standing wave also because the foam vibration-damping sheet is difficult for reflective sound wave, and acoustical quality is better.
The utility model can reach following effect:
1, the basic reason that produces according to standing wave of this programme: the reflection of face and loudspeaker towards the redesign of controlling eliminate the common acoustical flaw of standing wave with calculating audio amplifier faceted pebble and loudspeaker position.
2, this programme can be eliminated the standing wave of pedestal audio amplifier in a large number, so that pedestal audio amplifier music effect is better.
