Description
Technical field
The present invention relates to a kind of solid sound box and its supporting microphone, the electroacoustic or acoustoelectric device belonged in electronic device.
Background technology
In order to true to nature, various microphones and audio amplifier, the thousands of members of expensive equipment are developed.But, due to
The sense of hearing of people is very sensitive, still recognizes quality gap.Such as one：In order to true to nature, some grand theater performances are without using raising
Sound device equipment.Such as two：Walked to the park of morning exercises, from various music, people are easy to tell true man and loudspeaker
The sound sung --- it is ignorant of vocal music knowledge.Such as three：Present home television set screen is big, clear, but just listens and just know
The audio amplifier sounding in road.So, in terms of electroacoustic true to nature or acoustoelectric device, in addition it is also necessary to which we go to explore.
The content of the invention
The task of the present invention is to invent a kind of solid sound box and its supporting microphone, and its audio amplifier sounding is more life-like.
The technical solution adopted for the present invention to solve the technical problems is：Solid sound box and its supporting microphone are planted, is included
Audio amplifier part and microphone part, the microphone part include microphone protective cover, microphone enclosure, microphone inner support, the audio amplifier portion
Dividing includes audio amplifier protective cover, casing of loudspeaker box, audio amplifier inner support, it is characterized in that：It is anti-towards the microphone in the microphone enclosure
Shield direction, some regularly arranged branch's microphones are installed on the microphone inner support, branch's microphone is strong sensing
Microphone, have a sound guide tube in front of each described branch's microphone；In the casing of loudspeaker box, towards audio amplifier protection
Cover direction, some branch's loudspeakers are installed on the speech box bracket, branch's loudspeaker is strong directional loudspeaker；Institute
The number, installation site, direction and branch's microphone for stating point loudspeaker correspond consistent；The sound of each branch's microphone
Frequency signal, by it is each it is self-corresponding be connected on the corresponding loudspeaker of branch all the way after audio-frequency amplifier amplifies signal all the way,
Each described branch's loudspeaker is fixed on one and led on cylinder record, and the end port for leading cylinder record reveals from the side of the audio amplifier
Go out；There are two rectangular rings in front of the audio amplifier, the inner edge of the ring is connected with straight-bar, the middle part of the straight-bar
There is fixing axle, the other end of the straight-bar has soft iron, and there is magnetic core coil on the opposite of the soft iron, and the magnetic core coil is connected to a certain
The audio signal of branch's microphone.The audio amplifier protective cover is fixed on sound in the front of the ring, the audio amplifier protective cover
Case outward flange, is not contacted with the ring.The outer wall for leading cylinder record is rigid, and inside scribbles deadener, each institute
The installation direction and the direction of the corresponding loudspeaker for stating the end port for leading cylinder record are vertical.In the ring and institute
The audio amplifier inwall stated between branch's loudspeaker is filled with quieter material.Leading note inside pipe wall in front of branch's microphone, which can have, to disappear
Sound tube.It is the characteristic of compressional wave using sound wave, by people that the operation principle of the present invention, which is,（Or other animals, musical instrument etc.）Send
Sound, the regularly arranged branch microphone different by pointing to extracts the sound for traveling to these points（These sound it is strong
Degree, the direction of propagation are different）, then the audio signal of each branch's microphone, is incited somebody to action by respective audio-frequency amplifier all the way
After signal amplification, it is connected on the corresponding loudspeaker of branch all the way, the installation site of branch's loudspeaker, direction are talked about with the branch
Cylinder is corresponded unanimously, is just reduced former stereo.In order to strengthen the directionality that microphone receives sound, at each described point
There is a sound guide tube in front of branch microphone, in order to prevent that leading note tube wall from reflecting distortion, leading note inside pipe wall there can be hush pipe.In order to
Prevent the vibration interference of loudspeaker vibrating diaphragm reverse side（Vibrating membrane reverse side promotes the direction of air and above on the contrary, reverse side vibration is believed
Reverberation can be caused by number reflexing to audio amplifier inwall）；Branch's loudspeaker is fixed on one and led on cylinder record, leads the end port of cylinder record from described
The side of audio amplifier is exposed, the outer wall for leading cylinder record is rigid, and inside scribbles deadener, such that vibrating membrane reverse side shakes
Dynamic interference does not exist in audio amplifier；The installation direction and the corresponding loudspeaker of the end port of cylinder record are led described in each
Direction is vertical, so that interference is minimum（The direction vertical efficiency of the import of centrifugal blower and outlet is best, 180 °
It is worst）.There are two rectangular rings in front of audio amplifier, being connected with the inner edge of ring in the middle part of straight-bar, straight-bar has fixation
Axle, the other end of straight-bar has soft iron, and there is magnetic core coil on the opposite of soft iron, and magnetic core coil is connected to the audio of a certain branch's microphone
Signal, the purpose is to the intensity size of audio signal, the closure sizes of two rings ring very light in weight and has in change
Elasticity, sound absorption (if acoustically effective is poor, sound-absorbing material can be coated), so, two mouths of two rings equivalent to people up and down
Lip, vocal cords of the sound equivalent to people of each branch's loudspeaker hair, each is led inside tracheae of the cylinder record equivalent to people, audio amplifier quite
In the mouth chamber of people.Such structure, does not reflect and disturbs, has three-dimensional reduction, it is ensured that and original sound is true to nature.Audio amplifier is protected
The front of the ring is covered on, audio amplifier protective cover is fixed on audio amplifier outward flange, is not contacted with ring, this ensure that can't see sound
" lip " of case, it appears attractive in appearance.If the unified this solid sound box formulated and its supporting microphone number, direction, installation position
Put, it is easy to which popularization uses this electroacoustic or acoustic-electric technology.
The beneficial effects of the invention are as follows its audio amplifier sounding is more life-like.
