Embodiment
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
Please refer to Fig. 1, Fig. 2 and Fig. 3, the multifunctional electroacoustic device 100 include with receiving space frame 1,
The vibrational system 2 for being immobilizated in frame 1, the oscillator 3 being contained in frame 1, the support oscillator 3 latch plate 4 and be fixed on
Bonnet 5 in frame 1.
The voice coil loudspeaker voice coil 22 that the vibrational system 2 includes vibrating diaphragm 21 and drives vibrating diaphragm 21 to vibrate, the voice coil loudspeaker voice coil 22 are provided with voice coil loudspeaker voice coil
Lead 221.Vibrating diaphragm 21 can be integrative-structure or Split type structure, in selectable other embodiment, also may be used
It is oscillating plate etc., is to implement as long as sounding can be realized.
In the present embodiment, the oscillator 3 is magnetic circuit system, and it includes magnetic bowl 31, is contained in the magnet steel 32 of magnetic bowl 31
And it is sticked and is contained in the pole piece 33 on magnet steel surface, the magnetic circuit system 3 in the frame 1.Magnet steel 32 and pole piece 33 are contained in
In magnetic bowl 31, magnetic gap is formed between magnet steel 32 and magnetic bowl 31, voice coil loudspeaker voice coil 22 is inserted in the magnetic gap.It is it should be noted that described
Magnetic circuit system both can be single magnetic circuit system or with multiple magnet steel multi-magnetic circuit system, it is corresponding or more
Magnetic gap is formed between individual magnet steel, can reach the purpose of the present invention.
The magnetic bowl 31 can be bowl structure or the other shapes with receiving space, in this embodiment party
It is bowl structure in formula, it includes bottom wall 313, from the vertically extending side wall 311 of bottom wall 313 and from side wall 311 to external vertical
The extension 312 of extension.
The latch plate 4 is hollow structure, and it is set in the outside of magnetic bowl 31, and is connected under the extension 312
On surface, the latch plate is connected in frame 1, so as to play a part of supporting magnetic circuit system 3.So, can cause described
The size of center magnetic path reaches maximum, so as to lift the acoustical behavior of multifunctional electroacoustic device and vibration performance.It may be selected
Other embodiment in, the oscillator 3 can also include being used to strengthen the balancing weight of oscillator vibration.
The bonnet 5 is hollow structure, including the use that the fixed part 51 of ring-type and self-fixed department 51 extend to the direction of oscillator 3
In the side wall 52 of limitation oscillator displacement.In the present embodiment, the side wall 52 is the close hollow bulb from the fixed part 51
53 end extends to be formed to the direction of oscillator 3.The fixed part 51 surrounds a hollow bulb 53, and the magnetic bottom of bowl wall 131 is backward
The orthographic projection in the direction of lid 5 is located in the hollow bulb 53, and the side wall 52 is cyclic structure and surround the magnetic bowl 31, so,
Can be stepped down out oscillation space to magnetic circuit system 3, can increase multi-functional zund-Burguet apparatus while magnetic circuit system performance is not influenceed
The vibration performance of part.
