Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
The utility model provides a kind of loud speaker, comprises voice coil loudspeaker voice coil and pedestal, and said pedestal comprises the fixed part that phonate hole is middle with being arranged on phonate hole, and the contact conductor of said voice coil loudspeaker voice coil is fixed at said fixed part.
Below in conjunction with accompanying drawing the utility model is further specified.
Please consult Fig. 1 and Fig. 2 simultaneously, wherein Fig. 1 is the solid assembling sketch map of a kind of preferred embodiments of the utility model loud speaker, and Fig. 2 is the perspective exploded view of loud speaker shown in Figure 1.Said loud speaker 10 comprises cover plate 11, vibrating diaphragm 12, voice coil loudspeaker voice coil 13, pedestal 14 and conducting strip 15.
Said cover plate 11 and said pedestal 14 corresponding matching surround receiving space and accommodate said vibrating diaphragm 12, said voice coil loudspeaker voice coil 13, and said cover plate 11 is covered on the opening part of said pedestal 14.
Said vibrating diaphragm 12 edges are erected at the side edge surface of said pedestal 14, and be folded in said cover plate 11 and shown between the pedestal 14, and the zone line of said vibrating diaphragm 12 can said relatively cover plate 11 and said pedestal 14 up-down vibration.
Said voice coil loudspeaker voice coil 13 1 ends connect said vibrating diaphragm 12, in the receiving space that cover plate 11 and said pedestal 14 surrounded under the other end was suspended at.The body of said voice coil loudspeaker voice coil 13 closes on said pedestal 14 and is provided with, and said vibrating diaphragm 12 closes on said cover plate 11 and is provided with.Said vibrating diaphragm 12 is accommodated in the receiving space that is arranged on said pedestal 14 with said voice coil loudspeaker voice coil 13.Said voice coil loudspeaker voice coil 13 comprises anode electrode lead-in wire 131 and negative electrode lead-in wire 132.
Said pedestal 14 is provided with phonate hole 141 and the fixed part 143 that is arranged on said phonate hole 141 centres at relative two inner side edges, and is specifically as shown in Figure 3.Said phonate hole 141 realizes that said cover plate 11 and said pedestal 14 surround the mutual perforation of receiving space and external environment condition, convenient when vibrating diaphragm 12 and voice coil loudspeaker voice coil 13 vibrations gas suction and release.Said phonate hole 141 integral body are rectangular, and said fixed part 143 is one grade of girder construction, and it is arranged on the zone line of said phonate hole 141, and said phonate hole 141 is divided into two parts.Said fixed part 143 is one-body molded with the edge of said phonate hole 141, the edge flush of its surface and said phonate hole 141.
Said conducting strip 15 is the contact conductor 131,132 of a connection voice coil loudspeaker voice coil 13 and the connector of external power source system, and its surface is provided with a plurality of pads (indicating).Said conducting strip 15 embedded said pedestal 14 inside that are arranged on, said pad is exposed in the said receiving space.One end of said contact conductor 131,132 is directly fixing with the corresponding welding of pad on said conducting strip 15 surfaces; And corresponding the electrical connection; The other end then with the corresponding electrical connection of body of said voice coil loudspeaker voice coil 13, realize that thus the external drive signal transfers to said voice coil loudspeaker voice coil 13 via said conducting strip 15, said contact conductor 131,132.
Simultaneously; The mid portion of said contact conductor 131,132 is then across said phonate hole 141 and fixed part 143; Contact conductor 131,132 and the said fixed part 143 corresponding affixed settings in surface across part; Wherein, said contact conductor the 131, the 132nd is fixed to said fixed part surface through the colloid bonding way, can also be that the mode through spot welding is welded on said fixed part 143 surfaces.
Please consult Fig. 2 once more; Because said contact conductor 131 is fixed on said fixed part 143 surfaces through electric welding or gluing mode; Said fixed part 143 is positioned at the centre position of said phonate hole 141; So when said contact conductor 131,132 during across said phonate hole 141, the intermediate portion directly is fixed on the said fixed part 143, said fixed part 143 is in the middle of phonate hole; Eliminated because the shortcoming that the reliability that the fixed position causes near the voice coil loudspeaker voice coil root reduces has been eliminated because the fixed position influences the shortcoming of pure tone near welding disking area simultaneously.
As shown in Figure 2; Fixed part described in this execution mode 143 only is provided with one in pedestal 14 1 sides; As the further improvement of above-mentioned execution mode, in other change execution modes, the width, quantity of fixed part 143 etc. can be set as required at phonate hole 141 places.
Said contact conductor 131 can be fixed on the said fixed part 143 through ejection formation or other mechanical means.
In other execution modes of the utility model; Said loud speaker 10 also comprises the magnetic circuit system that is arranged in the pedestal; Said magnetic circuit system comprises magnet steel, magnetic bowl and magnetic conductive board; Said magnet steel is arranged in the magnetic bowl, and said magnetic conductive board is arranged on the magnet steel, and said voice coil loudspeaker voice coil is arranged in the magnetic field between said magnet steel and the magnetic bowl.
Compared with prior art; The utility model loud speaker 10 is through being provided with fixed part 143 in the middle of phonate hole; Reach the purpose of fixed electrode lead-in wire 131,132; Thereby when vibrating diaphragm 12 drove gas flow, contact conductor 131,132 can not move with gas, thereby made the utility model loud speaker 10 have the balance of pure tone and reliability preferably.
More than be merely the preferred case study on implementation of the utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the utility model.
