Description
Technical field
The present invention relates to a kind of music equipment, but refer in particular to a kind of 360 ° of broadcasts of egg type audio amplifier of furred ceiling.
Background technology
Audio amplifier is the terminal of whole sound system, and its effect is that the audio frequency electric energy is converted to corresponding acoustic energy, and it is radiated the space.It 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 so 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.
Yet general audio amplifier all has certain broadcast angle, listens to sound in certain broadcast angle, can make people hear the sound that tonequality is higher, and after going beyond the scope, tonequality can descend, and can not be satisfied with people's demand.Existing audio amplifier mostly adopts multichannel or enlarges the coverage of high tone quality sound in the mode that rotation is play.
One piece of name of prior art is called " rotary loudspeaker box " (China Patent No. 00215069.7, Granted publication CN 2426256Y) patent, it mainly comprises loud speaker, sound box and way circuit thereof, it is characterized in that, sound box is by top board, intilted a plurality of side plate and base plate consist of the ceiling type voice box of axle center symmetry, be partitioned into horizontal closed voice box on the base plate by the audio amplifier internal partition, inclination reflex cabinet on the inclined side plate and cavity isolation chamber, the roof box symmetrical centre is provided with the rotating spindle vertical with top board, is connected with casing by the box body transmitting mechanism of driven by motor.The above-mentioned motor that utilizes realizes that by transmission mechanism casing rotates, thereby realizes that sound can omnibearingly spread out.But, above-mentioned patent is play in the mode of a broadcast by being installed on the casing a plurality of loud speakers, and can there be some beats in each loud speaker when playing, so that the quality of sound is not very high, because casing rotates, so, will be so that the beat that people hear be a burst of, and the supper bass difficulty distinguishes, still is not enough to satisfy people to requirement stable, soft, uniform tonequality.
Summary of the invention
The technical problem that one, will solve
The objective of the invention is for the existing the problems referred to above of prior art, the spy provides a kind of compact conformation, minimum space ceiling capacity sounding, environmental protection, energy-conservation and can stablize, 360 ° of soft, the egg type simple sound sources that play sound uniformly play audio amplifier.
Two, technical scheme
