Abstract
The utility model discloses a folding sound box, which comprises a main shell. A power supply and a sound box control circuit are arranged in the main shell. A first sound box and a second sound box are arranged at two sides of the main shell. Rotation shafts are arranged between the first sound box and the main shell and between the second sound box and the main shell. The first and second sound boxes are pivoted to the main shell through the rotation shafts. A tweeter unit is disposed in both the first sound box and the second sound box. A woofer unit is arranged in both the first sound box and the second sound box. In comparison with the prior art, as the independent first and second sound boxes are arranged and are pivoted to the main shell, the folding sound box is in a flat state when not in use, thus being beneficial to being taken and contained by users; and the folding sound box is in an upright state when in use. When the folding sound box is used, the first and second sound boxes are rotated to an angle of 45 degrees. Thus, the sound box stands up, and timbre of the sound box is raised.
Description
Technical field
The utility model relates to audio amplifier, especially a kind of collapsible audio amplifier.
Background technology
Along with high-speed development of science and technology, audio amplifier is as the terminal of whole sound system, and its effect is that the audio frequency electric energy is converted to corresponding sonic energy, and it is radiated the space.Audio amplifier is the extremely important part of sound system, because it is being undertaken and the signal of telecommunication is transformed into acoustical signal is directly listening to this mission critical for people's ear, it is wanted directly and people's the sense of hearing is come into contacts with, and people's the sense of hearing is very sensitive, and the tone color of complex sound is had very strong resolving ability.Because people's ear is estimated the most important standard of a sound system tonequality quality just to the subjective feeling of sound, therefore, can think that the performance height of audio amplifier is to play key effect to the playing quality of a sound system.Yet the design of existing audio amplifier has been ignored people to requirement portable and that hommization is operated when constantly satisfying people tonequality is required, and especially under the desk-top space condition of limited, existing plat sound box can't be upright, causes audio not good.
Summary of the invention
For overcoming the deficiency of prior art, the purpose of this utility model provides a kind of being easy to carry about with one and collapsible audio amplifier that LF-response is strong, and it is simple in structure, it is low, user-friendly for operation to cause.
For achieving the above object, technical scheme provided by the utility model is: a kind of collapsible audio amplifier, comprise main casing, in described main casing, be provided with power supply and audio amplifier control circuit, be provided with first audio amplifier and second audio amplifier in described main casing both sides, be provided with rotation axis between described first audio amplifier and second audio amplifier and the main casing, described first audio amplifier and second audio amplifier and main casing are articulated by described rotation axis, in described first audio amplifier and second audio amplifier, be provided with the loudspeaker unit, be provided with the bass horn unit at described first audio amplifier and second audio amplifier.Compared with prior art, the beneficial effects of the utility model are, owing to be provided with independently first audio amplifier and second audio amplifier, and first audio amplifier and second audio amplifier and main casing are articulated, both made this audio amplifier when not using, be dull and stereotyped state, and be beneficial to the user and carry and take in; Make this audio amplifier be erectility in use again, during use, rotate first audio amplifier and second audio amplifier, can uprightly play audio amplifier, improve the tonequality of audio amplifier to miter angle.
As specializing, described audio amplifier control circuit includes audio decoder chip, power amplifier chip, source of sound module, liquid crystal touch control module and key-press module, and described power amplifier chip, source of sound module, liquid crystal touch control module, key-press module and power supply are electrically connected with the audio decoder chip respectively.
As improvement, in described main casing, be provided with bluetooth radio module, described bluetooth radio module is electrically connected with the audio amplifier control circuit.Owing to be provided with bluetooth radio module, this audio amplifier can be connected the trouble of having avoided connecting line to take in and put by wireless with source of sound.
As improvement, on described main casing, be provided with the liquid crystal touch control display screen, described liquid crystal touch control display screen is electrically connected with the audio amplifier control circuit.Owing to be provided with the liquid crystal touch control display screen, make things convenient for user's digitlization operation.
As improvement, on described main casing, be provided with the control button, described control button is electrically connected with the audio amplifier control circuit.
As improvement, on described loudspeaker unit and bass horn unit, be provided with the metal coating net.Owing to be provided with the metal coating net, can play dustproof and crashproof effect.
