Description
Technical field
The present invention relates to electrical equipment, is to be related to a kind of stereo set especially.
Background technology
Current audio amplifier, mainly includes casing and loudspeaker；Loudspeaker is in the casing, and sound basin is towards front.Its
In, a magnet exciting coil for being coupled in source of sound power amplifier is fixed at the sound basin rear of loudspeaker, and coil rear is then a permanent magnet,
Magnet exciting coil is in the magnetic field of permanent magnet, and the electric current in magnet exciting coil changes with source of sound, so that magnet exciting coil is relative to forever
Magnet vibrates, so as to promote the sound basin vibration sounding.Under this mechanism, sound produced by the vibration of sound basin can only push forward,
The directionality of sound is relatively strong, it is impossible to is difficult to make the audience of each position in space to enjoy the consistent music of effect；It is another
Aspect is therefore, obvious by producing when loudspeaker reduces voice because architectural feature and the human body trunnion of sound basin differ greatly
Distortion, i.e., it is true voice or sound that audience, which can substantially distinguish, therefore, current stereo set for voice also
The former sense of reality is still weak.
The content of the invention
In view of the above-mentioned problems, it is an object of the invention to provide a kind of wikipedia type sound equipment, the wikipedia type sound equipment not only can be with
Basically identical acoustics is provided to all directions, and during voice is simulated, there is the superior sense of reality.
The technical solution adopted for the present invention to solve the technical problems is：The wikipedia type sound equipment includes pedestal, the pedestal
On fix a c-type electromagnet, two ends of the c-type electromagnet form opposite pole facing each other；Described two
A bellows being made up of diaphragm of loudspeaker material is connected between opposite pole；The bellows surface is equidistantly gathered and ripple
Manage coaxial closure wire loop；Power amplifier module and electricity of the magnet exciting coil electrical couplings of the electromagnet in the pedestal
Source module.
Preferably, the diaphragm of loudspeaker material is one kind in common paper membrane, coating paper membrane, resin film, glass film.
Preferably, the both ends of the bellows connect the magnetic pole, further, institute by ring-type fold rubber respectively
State and offer stomata on ring-type fold rubber, be the flexible elimination effects of air pressure of the bellows.
Preferably, the closure metal loop wire of the bellows surface makes as follows：First, in the bellows table
Face is coated with metallic film；2nd, etched on the metallic film, make bellows surface formed with bellows it is coaxial, mutually face
Near and mutually insulated closure wire loop；Further, when being etched to the metallic film, etching head surface coats
Coating of wax oil.
The beneficial effects of the present invention are：At work, tone currents caused by source of sound is through power amplifier mould for the wikipedia type sound equipment
Exciting current as the c-type electromagnet after block amplification, magnetic field caused by electromagnet is with tone currents real-time change, and the magnetic
Field forms ellipsoid between two opposite poles of c-type electromagnet, middle vertical plane of its magnetic field intensity in two opposite pole lines
On it is most weak, and be incremented by from the middle vertical plane to both sides, until at magnetic pole；It is whole when the increase of tone currents instantaneous value according to Lenz's law
When body magnetic field intensity strengthens, the closure wire loop on bellows will move to suppress the increase of magnetic flux to the middle vertical plane
It is dynamic, promote whole bellows to central contraction；Conversely, when tone currents instantaneous value reduction, global magnetic field remitted its fury, ripple
Pipe expands to both ends；So that the bellows follows source of sound to vibrate, i.e., source information is externally exported in the form of sound；Due to
Bellows is exposed in space, is not blocked by any, therefore it will produce basically identical acoustics to space all directions,
And the shape and structure due to bellows and human body trunnion are quite similar, so when feeding back voice, the sense of reality is extremely strong, extremely has
Sung opera arias beneficial to fan's exercise is sung.
Brief description of the drawings
Fig. 1 is one embodiment schematic diagram of this wikipedia type sound equipment.
Fig. 2 is the magnetic field schematic diagram of c-type electromagnet in Fig. 1 embodiments.
Embodiment
In the embodiment shown in fig. 1, the wikipedia type sound equipment includes pedestal 1, and a c-type electromagnetism is fixed on the pedestal 1
Iron 2, two ends of the c-type electromagnet 2 form opposite pole 21,22 facing each other；When the solenoid is energized, this two
Anticipate as shown in phantom in Figure 2 in magnetic field between opposite pole 21,22.
A bellows 3 being made up of diaphragm of loudspeaker material is connected between described two opposite poles 21,22；It is described
Equidistantly gather on the surface of bellows 3 the closure wire loop coaxial with bellows（It is not shown）；The magnet exciting coil electricity of the electromagnet 2
Property power amplifier module and power module of the coupling in the pedestal 1.
Above-mentioned wikipedia type sound equipment, the diaphragm of loudspeaker material are common paper membrane, coating paper membrane, resin film, glass film
In one kind, certainly, if any the diaphragm of loudspeaker newly developed, can use.
Above-mentioned wikipedia type sound equipment, the closure metal loop wire on the surface of bellows 3 make as follows：First, in institute
State the surface of bellows 3 and be coated with metallic film；2nd, etched on the metallic film, form bellows surface same with bellows
Axle, adjacent to one another and mutually insulated closure wire loop.In addition, preferably, carried out to the metallic film
During etching, etching head surface coats coating of wax oil, can be at the interval between carving closure wire loop by this method for optimizing
Meanwhile applied in the interval and be covered with insulating wax oil, so as to ensure the good insulating properties between adjacent closure wire loop.
At work, tone currents caused by source of sound is used as the c-type to above-mentioned wikipedia type sound equipment after power amplifier module amplifies
The exciting current of electromagnet 2, magnetic field is with tone currents real-time change caused by electromagnet, and the magnetic field is the two of c-type electromagnet 2
Form ellipsoid between individual opposite pole 21,22, its magnetic field intensity two opposite poles 21,22 lines middle vertical plane P on it is most weak,
And be incremented by from the middle vertical plane to both sides, until at magnetic pole；According to Lenz's law, when the increase of tone currents instantaneous value, global magnetic field
During intensity enhancing, the closure wire loop on bellows 3 will move to suppress the increase of magnetic flux to the middle vertical plane P, promote
Make whole bellows 3 to central contraction；Conversely, when tone currents instantaneous value reduction, global magnetic field remitted its fury, bellows 3
Expanded to both ends；So that the bellows 3 follows source of sound to vibrate, i.e., source information is externally exported in the form of sound；Due to
Bellows 3 is exposed in space, is not blocked by any, therefore it is imitated to space all directions by basically identical sound equipment is produced
Fruit, and the shape and structure due to bellows 3 and human body trunnion are quite similar, so when feeding back voice, the sense of reality is extremely strong, ten
Point be advantageous to sing fan's exercise and sing opera arias.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
