Abstract
The utility model discloses an ultra-thin loudspeaker which comprises a basin frame group (1), a magnet group (2), a voice coil (3), a pressing edge (4) and a wiring frame (5). The cone-shaped surface of a vibrating diaphragm (6) of a paper cone is provided with triangular reinforcing ribs with different lengths, and the upper side of the periphery of a center hole of the vibrating diaphragm (6) is glued with a top dome dust-proof cover (7) with a major diameter. The vibrating diaphragm (6), a large centering support chip (8) and the voice coil (3) are glued together to form a loudspeaker vibration system, and the voice coil (3) is inserted and arranged in a circular magnetic gap of the magnet group (2). The vibrating diaphragm (6) is glued at the upper side of the inner periphery of a folding ring (9), and the outer periphery of the folding ring (9) is pressed and glued on the upper side of the oblong periphery of the basin frame group (1) by the pressing edge (4). The integral height of the loudspeaker is 24 millimeters, and the acoustic performance surpasses a traditional loudspeaker with the height of 50 millimeters in the same type. The utility model is a special loudspeaker which is extremely suitable for modern liquid crystal and plasma panel TV sets.
Description
Technical field
The utility model belongs to a kind of electro-acoustic element.It relates to the super-thin speaker that modern liquid crystal, plasma flat-screen televisions machine are used specifically.
Technical background
At present, China's television set quality status reaches international standards, from traditional analog signal picture tube television set, develop into the liquid crystal of digital signal, the plasma flat-screen televisions machine, therefore, having proposed its device for the needs in market are urgent must be toward small-sized, the new problem of slimming design, this problem is the ultrathin design of research loud speaker, general flat-panel television loud speaker height is 50 millimeters, here refer to the full frequency band loud speaker, modern panel TV set complete machine thickness only is 30 millimeters, the height of apparent loud speaker should could adapt to the requirement of panel TV set less than 30 millimeters, and is supporting with it, therefore, it is very urgent to be eager to develop ultrathin high-quality loud speaker.
Summary of the invention
The purpose of this utility model is to develop a kind of super-thin speaker that is specially adapted to various flat-plate television sets, it highly only is 24 millimeters, and tonequality and performance satisfy the loud speaker of panel TV set requirement fully all above conventional loudspeakers as power, frequency response, sensitivity and physical property thereof.
The utility model is realized by following step, see accompanying drawing 1 or 2, it comprises basin frame group (1), magnet group (2), voice coil loudspeaker voice coil (3), flanging (4), patch bay group (5), it is characterized in that: have the triangle reinforcement that is uneven in length on the cone face of cone vibrating diaphragm (6), bonding major diameter ball top shape dust cover (7) on vibrating diaphragm (6) centre bore circumference, vibrating diaphragm (6), big centring disk (8), the bonding continuous formation speaker vibration system of voice coil loudspeaker voice coil (3) three, its voice coil loudspeaker voice coil (3) inserts and is assemblied in magnet group (2) the circle shape magnetic slit, vibrating diaphragm (6) is bonded in ring (9) above the inner rim, and the neighboring of ring (9) is pressed through flanging (4) and is bonded on the Long Circle periphery of basin frame group (1).
The triangle reinforcement of cone vibrating diaphragm (6) is at long axis direction, and on its axis is the longest, be above projection, below be recessed, totally 3 to 7 reinforcements, and be radial.
Cone vibrating diaphragm (6) from the top to following whole height be 5 millimeters.
Ring (9) should adopt a compression moulding of high-density foam material.
Advantage of the present utility model and good effect: (one) super-thin speaker is the supporting design of panel TV set specially, it highly is 26 millimeters, adapt to the requirement of panel TV set structural design fully, thin 22 millimeters of this super-thin speakers than similar identical loudspeaker; (2) conventional loudspeakers cone vibrating diaphragm geometry can cause frequency response trend unevenness greater than 20dB, and high band can not reach 20000HZ, the utility model has designed major diameter ball top shape dust cover and voice coil loudspeaker voice coil and cone vibrating diaphragm and has been complementary, to reduce the ante-chamber degree of depth, the influence of the thin centering high band of cone vibrating diaphragm can be remedied, the acoustic performance of medium-high frequency section can be improved; (3) the cone-shaped surface design of cone vibrating diaphragm is radial triangle reinforcement, has improved cone intensity, has guaranteed that cone is having only the needed intensity of space internal vibration of 5 millimeters height, suppress the cone medium-high frequency and cut apart vibration, reduce the unevenness of frequency response, improve tonequality, see accompanying drawing 2.
Description of drawings
Fig. 1 is the super-thin speaker profile, wherein: the 1st, basin frame group, the 2nd, magnet group, the 3rd, voice coil loudspeaker voice coil, the 4th, flanging, the 5th, patch bay group, the 6th, cone vibrating diaphragm, the 7th, ball top shape dust cover, the 8th, centring disk, the 9th, ring.
Fig. 2 is a cone vibrating diaphragm front view.
Embodiment
Be described further with reference to 1 pair of the utility model of accompanying drawing: (one) is at the long axis direction on the cone surface of cone vibrating diaphragm (6), design is the triangle reinforcement of radial waveform, see accompanying drawing 2, and the triangle on the axis is the longest, it is the phase place phase antiresonance that is produced when cone vibrates in order to reduce, described long axis direction is radial waveform and is meant that the triangle reinforcement on the vertical axis is the longest, the length of the triangle reinforcement that it is upper and lower symmetry is respectively successively decreased, this geometry all makes moderate progress to acoustic performance such as frequency response, two sound accompaniment except that improving cone intensity; (2) magnet group (2) must adopt the higher neodymium iron boron magnetic body of permeability, and should adopt diameter is the magnet of 19 millimeters of φ, just can reach the high sensitivity requirement; (3) must adopt big centring disk (8) in order to satisfy the low frequency acoustical quality, ring (9) adopts high-density foam material to improve low frequency with assurance, and stereovision is better.(4) voice coil loudspeaker voice coil (3) should guarantee with magnet group (2) with one heart, could realize that voice coil loudspeaker voice coil (3) inserts to be assemblied in the magnetic slit of magnet group (2); (5) voice coil loudspeaker voice coil (3) two ends lead-in wire should adopt the reliability of metal knitted line of multiply and patch bay group (5) two ends welding can raising super-thin speaker.
