Thin vibration of membrane carrys out sounding, and the movement of voice coil is become the movement for whole plate as a result, and the movement of whole plate can homogenize PU films
Stress reduces the case where PU films are distorted because of the generation 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 PU thin film centers portion and PU film sides edge are integrally formed.PU film sides edge is not
Fixed substrate is installed, the deformability degree of PU film sides edge increases, and can optimize broadcasting for the low-frequency sound of the utility model as a result,
Put effect.
In some embodiments, 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 utility model.
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 ideal.
In some embodiments, the upper bracket is equipped with upper accommodating chamber, first magnet be it is multiple, 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 bracket is equipped with lower accommodating chamber, second magnet be it is multiple, 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 bracket are equipped with through-hole.Sound can be convenient for from upper bracket as a result,
It is flowed out in the through-hole of lower bracket.
