Using this application provides loudspeaker, the thickness width size of loudspeaker is not only reduced, is easy to make strip
And distortion is not easy, it is more suitable for ultra-thin flat plate television or ultra-thin ultra-narrow audio amplifier uses.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with drawings and Examples pair
The present invention is further described.The system schematic that Fig. 3 is the present invention is three-dimensional structure signal；Put down the side that Fig. 4 is the present invention
Face is end view.
The ultra-thin Elongated loudspeaker device of a kind of ultra-narrow provided by the invention includes：
This example is strip magnet using two magnets, is fixed on peripheral frame i.e. frame intralamellar part；The two magnets can be adopted
With two strip cuboid powerful permanent magnetic irons, this peripheral frame can be made of materials such as plastics or metals；Two magnets are parallel
Place and fix, between have gap, the adjacent surface of two magnets is respectively S and N poles, can produce magnetic field between gap therebetween；
Printed circuit board is placed in parallel among magnet gap, and printed circuit board keeps very little gap apart from both sides magnet,
This example about 1mm；Printed wiring is designed with printed circuit board, this example uses two sided pcb, devises a toroid
Road, circuit both ends can connect the output of audio power amplifier, when power amplifier output current passes through circuit, produce Lip river under the influence of a magnetic field
Lun Zili, this is pushed dynamic printed circuit board and moved up and down；
The upper edge of printed circuit board is fixed on positioner i.e. on stationary positioned bar, and lower sid strip is fixed on shaking device
On；Positioner can be made of rubber or other elastomeric materials, and this example uses rubber strip, and shaking device can use cone or carbon
Fiber and other material is made, and the shapes such as taper or plane can be made in its shape, and this example uses plane cone；Cone edge passes through soft
Soft rubber or other elastomeric materials are connected in peripheral frame, are easy to cone to shake using soft rubber；Positioner and shaking device
Effect be jointly by the position limitation of printed circuit board in the centre position of magnet gap, avoid printed circuit board from being touched in motion
Noise is produced to magnet；Shaking device vertical tremor sounding is driven when printed circuit board moves up and down；
Because printed circuit board is strip, this size about 12mm*100mm, cone uses rectangular planes cone, its
Narrow side can be made smaller, and this example is 17mm*120mm, and the long side of printed circuit board is all connected among plane cone plane,
And the long side of printed circuit board corresponds to the long face of cone, the motion of printed circuit board can quickly and uniformly be delivered to cone,
Cone uniform force, is not likely to produce deformation, also avoids the distortion of sounding；
Due to the ultra-thin ultra-narrow of the speaker unit and elongated strip shaped is easily able to, its is preferably for current flat board electricity
Depending on that freely can place or be embedded in following or the right and left of flat panel TV, flat panel TV outward appearance especially frame will not be made
Type causes to significantly affect；Or suitable for soundbar strip audio amplifiers, it is more suitable for matching flat panel TV use.
Beneficial effect is：The thickness width size of loudspeaker is reduced, is easy to make strip and is not easy distortion, it is preferably
Used in ultra-thin flat plate television or ultra-thin ultra-narrow audio amplifier.
