Relatively.
The beneficial effects of the invention are as follows：In the present invention, the first magnet and the second magnet can generate constant magnetic field so that sound
Circle can be in moving in magnetic field, and the athletic meeting of voice coil drives the vibration of tablet overlay film compound film sheet, so as to generate sound.And due to
Diaphragm uses tablet overlay film form, and diaphragm is plate-like, and in vibration, the movement of its total is the translation of constant amplitude substantially
Movement will not generate distortion because Oscillation Amplitude is different, can guarantee the integrality of sound, and the reduction degree of sound is high, after tested, this
Invention is still true to nature for the result of broadcast of the high-frequency sound of 60kHz.
In some embodiments, tablet overlay film compound film sheet includes PU (Polyurethane, i.e. polyurethanes)
Film, fixed substrate, polyester film and copper ring stent, the copper ring branch are provided with inner cavity, and the PU films are mounted on inner cavity,
The fixed substrate is mounted on PU films, and the polyester film is mounted in fixed substrate, and the voice coil is fitted in polyester
On film.In the present invention, the athletic meeting of voice coil causes the movement of entire fixed substrate, and the movement of final fixed substrate causes PU films
Vibration carry out sounding, the movement of voice coil is become for the movement of whole plate as a result, the movement of whole plate can homogenize PU films by
Power reduces situation of the PU films because of the generation distortion of different piece unbalance stress.
In some embodiments, the PU films include PU thin film centers portion and PU film sides edge, the fixed base
Plate is mounted in PU thin film centers portion, and the PU thin film centers portion and PU film sides edge are integrally formed.PU film sides edge is not
Fixed substrate, the deformability degree increase of PU film sides edge are installed, the broadcasting that can optimize the low-frequency sound of the present invention as a result, is imitated
Fruit.
In some embodiments, the PU film sides edge take the shape of the letter U, one kind in S-shaped or waveform.On as a result,
The movement distortion of PU film sides edge can be efficiently reduced by stating shape, improve the result of broadcast of the present invention.
In some embodiments, the width of PU film sides edge is 3mm~5mm.It is measured through many experiments, PU film sides
In the range, the distortion of PU film sides edge is in tolerance interval, for low-frequency sound and high-frequency sound for the width of edge
Resultant effect best suit using preferable.
In some embodiments, the upper bracket is equipped with upper accommodating chamber, and first magnet is multiple, and the multiple the
One magnet is installed in accommodating chamber.Upper accommodating chamber can be convenient for the installation and fixation of the first magnet, improve consolidating for the first magnet
Determine reliability.
In some embodiments, the lower carriage is equipped with lower accommodating chamber, and second magnet is multiple, and the multiple the
Two magnet are installed in lower accommodating chamber.Lower accommodating chamber can be convenient for the installation and fixation of the second magnet, improve consolidating for the second magnet
Determine reliability.
In some embodiments, the upper bracket and lower carriage are equipped with through hole.It can be convenient for sound as a result, from upper bracket
It is flowed out in the through hole of lower carriage.
