Abstract
The utility model discloses a miniature flat-panel speaker, comprising a main shell body, wherein one side of the main shell body is provided with a fixed plate, more than one woofer is fixedly arranged on the fixed plate, two sides of the fixed plate are provided with speaker outer frames, and tweeters are fixedly arranged on the speaker outer frames; the other side of the main shell body is provided with sound diffusing holes; and a power amplification chip, a sound source module, a liquid crystal touch control module and a key module of a speaker control circuit as well as a power supply are respectively and electrically connected with an audio decoding chip. Compared with the prior art, since the woofers are arranged on the fixed plate, the tweeters are arranged on the speaker outer frames, and the other side of the main shell body is provided with more than one sound diffusing holes, thus the woofers and the tweeters can be isolated so as to avoid mutual vibration interference, and the woofers and the tweeters can achieve the best sound effect.
Description
Technical field
The utility model relates to audio amplifier, especially a kind of miniature plate 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 Miniature acoustics in the existing design has outside the advantage of operating simple and easy and profile fashion, and weak point is also arranged, and especially has bigger flaw on acoustical quality, and its bass tonequality and three-dimensional equilibrium degree all can't reach preferable degree.In addition, existing Miniature acoustics mostly is cylinder design, and it is big to take up room, and when travelling away from home, carries inconvenience.
Summary of the invention
For overcoming the deficiency of prior art, the purpose of this utility model provides a kind of miniature plate audio amplifier that can promote bass and high pitch tonequality, and can save placement space, is convenient to go out to carry.
For achieving the above object, technical scheme provided by the utility model is: a kind of miniature plate audio amplifier, comprise main casing, power supply and audio amplifier control circuit, described audio amplifier control circuit is arranged in the main casing, side at described main casing is provided with fixed head, on described fixed head, be fixed with more than one bass horn, be provided with the audio amplifier housing, on described audio amplifier housing, be fixed with loudspeaker in the both sides of described fixed head; Opposite side at described main casing is provided with diffusing sound hole; 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.Compared with prior art, the beneficial effects of the utility model are, because bass horn is arranged on the fixed head, and loudspeaker is arranged on the audio amplifier housing, and the opposite side at main casing is provided with more than one diffusing sound hole, can either isolate bass horn and loudspeaker, avoid producing vibrations mutually and disturb, the two is reached cause best acoustical quality; Secondly owing to be provided with liquid crystal touch control module and key-press module, make things convenient for the user to operate the audio type and the volume of control audio amplifier.
As improvement, the one side that described main casing is provided with the sound hole that looses is provided with bracing frame, and support frame as described above and main casing articulate.This structure makes things convenient for the user to open bracing frame, on miniature plate audio amplifier vertical fixing desktop, improves acoustical quality.
As improvement, on described audio amplifier housing, be provided with audio output interface.
As improvement, on described loudspeaker and fixed head, be respectively equipped with the metal coating net.Can protect the interior loudspeaker of main casing owing to be provided with the metal coating net.
As specializing, described audio decoder chip is a CS4299-JQZ model audio decoder chip.
Description of drawings
Fig. 1 is a cutaway view of the present utility model.
Fig. 2 is the structure chart of audio amplifier control circuit.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
As illustrated in fig. 1 and 2, a kind of miniature plate audio amplifier that present embodiment provided, comprise main casing 1, power supply 2 and audio amplifier control circuit 3, described audio amplifier control circuit 3 is arranged in the main casing 1, side at described main casing 1 is provided with fixed head 4, on described fixed head 4, be fixed with three bass horns 6, be provided with audio amplifier housing 5, on described audio amplifier housing 5, be fixed with loudspeaker 7 in the both sides of described fixed head 4; Opposite side at described main casing 1 is provided with three diffusing sound holes 8; Described audio amplifier control circuit 3 includes audio decoder chip 31, power amplifier chip 32, source of sound module 33, liquid crystal touch control module 34 and key-press module 35, described power amplifier chip 32, source of sound module 33, liquid crystal touch control module 34, key-press module 35 and power supply 2 are electrically connected with audio decoder chip 31 respectively, wherein, described audio decoder chip 31 is a CS4299-JQZ model audio decoder chip.In addition, the one side that described main casing 1 is provided with the sound hole 8 that looses is provided with bracing frame 9, and support frame as described above 9 articulates with main casing 1, and this structure makes things convenient for the user to open bracing frame 9, on miniature plate audio amplifier vertical fixing desktop, improves acoustical quality; And on described audio amplifier housing 5, also be provided with audio output interface 10; On described loudspeaker 7 and fixed head 4, be respectively equipped with metal coating net 11, can protect loudspeaker in the main casing 1 owing to be provided with metal coating net 11.
The advantage of miniature plate audio amplifier is in the present embodiment, because bass horn 6 is arranged on the fixed head 4, and loudspeaker 7 is arranged on the audio amplifier housing 5, and the opposite side at main casing 1 is provided with the sound hole 8 that looses, can either isolate bass horn 6 and loudspeaker 7, avoid producing vibrations mutually and disturb, the two is reached cause best acoustical quality; Secondly owing to be provided with liquid crystal touch control module 34 and key-press module 35, make things convenient for the user to operate the audio type and the volume of control audio amplifier.
