Background

The sound refers to sounds other than human speech and music, and includes sounds of natural environments, sounds of animals, sounds of machine tools, various sounds generated by human motions, and the like. The sound equipment comprises a sound box, peripheral equipment (comprising a pressure limiter, an effector, an equalizer, a VCD, a DVD and the like), a loudspeaker (a sound box and a loudspeaker), a sound console, a microphone, display equipment and the like. Wherein, the sound box mainly comprises sound output equipment, a loudspeaker and a subwoofer.

The main improvement to the sound box at present stage lies in expanding its function, improving its stability of working to and the improvement to tone quality, and to the improvement of tone quality, many opinions adopt precious material, through the mode that raises the cost, promote the quality of sound generating equipment. The applicant also made improvements to the tone quality adjustment of the sound box, for example, the improvement of the voice coil is proposed, the high temperature resistance of the voice coil is improved, the stable and safe tone output for a long time is realized, and the surface of the cotton wire is coated with an insulating layer, so that the service life of the equipment is prolonged. For another example, through the improvement to the cotton silk wire mounted position, make the vibrations of loudspeaker body reach a stable state, and then the tone quality that sends is more balanced, and the emergence effect of audio amplifier is better.

In the published patent document, the patent with application number 200420019860.1 named as winding voice coil with square wire discloses a technique for winding voice coil with square wire, which improves the utilization rate and sensitivity of magnetic circuit, improves the heat transfer and heat dissipation performance of voice coil, and is beneficial to further improving the power of loudspeaker.

However, technicians find that the output sound quality of the sound box is low in accent and not beautiful enough as an important part for kinetic energy transmission in long-time work.

Disclosure of Invention

The utility model aims at providing a voice coil loudspeaker voice coil for loudspeaker of improvement output tone quality in order to solve the problem that the voice coil loudspeaker voice quality still waited to improve among the prior art.

The utility model has the following concrete scheme:

the loudspeaker comprises a loudspeaker arranged in a sound box, the loudspeaker comprises a horn-shaped vibrating diaphragm arranged in a basin frame, folding rings and clamping plates arranged at two ends of the horn-shaped vibrating diaphragm, and an electromagnetic vibration mechanism arranged at the other side of the clamping plates, wherein a spring piece is arranged between the clamping plates and the horn-shaped vibrating diaphragm, a cotton wire is arranged between the electromagnetic vibration mechanism and the horn-shaped vibrating diaphragm, and the voice coil is arranged in the electromagnetic vibration mechanism and comprises a bobbin and two voice coil wires which are tightly wound on the bobbin one by one and are adjacent to each other; the two voice coil wires are respectively made of aluminum wires with square cross sections and copper wires with round cross sections.

In a specific implementation, the side length of the aluminum wire corresponds to the diameter of the copper wire. The side length and the diameter are less than 0.3 mm.

And the surface of the voice coil wire is coated with light red insulating paint. The thickness of the light red insulating paint is less than 0.2 mm.

The beneficial effects of the utility model reside in that:

effectively eliminates the noise and improves the output effect of the tone quality. The sensitivity of the equipment is improved due to the small magnetic gap of the new design;

the area of the cross section of the line is large, so that clear transmission of tone quality, particularly clear transmission of high frequency, is ensured;

the aluminum material is light in weight, so that the vibration quality is light in the working process, the aluminum wire is a square wire, the side length is set to be consistent with the diameter of the round copper wire, the balance of the wavelength of the transmitted tone can be ensured, the upper limit of the corresponding finished product tone is high, and the extension degree of the tone bandwidth is high; the coated insulating paint is light red transparent paint, so that the transmission of alternating current vibration is facilitated, and the quality of timbre is further ensured.

FIG. 1 is a front view of the structure of the present invention;

fig. 2 is an enlarged schematic view of a voice coil portion of the present invention;

names of components in the drawings: 1. a basin stand; 2. a horn-shaped diaphragm; 3. folding the ring; 4. a spring plate; 5. a voice coil; 6. a cotton wire; 7. a connecting sheet of the cotton wire lead and the horn-shaped vibrating diaphragm; 8. a copper wire; 9. and an aluminum wire.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Example 1

A kind of voice coil used for loudspeaker which improves the output tone quality, refer to fig. 1 to fig. 2, in the design, the loudspeaker includes the loudspeaker installed in the sound box, the loudspeaker includes the loudspeaker-shaped vibrating diaphragm 2 installed in basin frame 1, install folding ring 3 and clamp plate, electromagnetic vibration mechanism installed on the opposite side of clamp plate at both ends of said loudspeaker-shaped vibrating diaphragm 2, install the spring leaf between clamp plate and loudspeaker-shaped vibrating diaphragm 2, set up the cotton wire 6 between electromagnetic vibration mechanism and loudspeaker-shaped vibrating diaphragm 2, the voice coil 5 is set up in said electromagnetic vibration mechanism, include bobbin and close and adjacent two voice coil wires twined on said bobbin one by one; the two voice coil wires are respectively made of an aluminum wire 9 with a square cross section and a copper wire 8 with a circular cross section. In the course of the work, because square line and circular line closely arrange, equipment has had littleer magnetic gap, so sensitivity is higher, simultaneously, effectively utilize the light and copper line 8 heavy nature of 9 aluminum wires, the output of high pitch is carried out more to the matter light, and the output of low pitch is carried out to the matter heavy, and equipment audio output wide range closely arranges and reduces magnetic gap.

The dimension of the side length of the aluminium wire 9 corresponds to the dimension of the diameter of the copper wire 8. The side length and the diameter are less than 0.3 mm. And the surface of the voice coil wire is coated with light red insulating paint. The thickness of the light red insulating paint is less than 0.2 mm. In this embodiment, the length of a side is corresponding with the diameter size, and the electric current that passes through on each circuit is equivalent, can not influence the equilibrium of tone output, and the purpose of light color insulating varnish coating lies in, avoids the carbon black material in the dark color insulating varnish, and carbon black itself possesses certain current mobility and still can form electromagnetic current and influence tone quality.

In the present embodiment, it seems that the improvement point is local, and the improvement of the entire mass and the local shape is slight, however, in the sound transmission process, the mass reduction by 1g is affected by the improvement of the voice coil 5 which is the most critical portion.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof.
