Problems solved by technology

However, according to the existing technology, circular speakers are more convenient to design and adjust in terms of sound quality and sensitivity due to their symmetrical characteristics. However, when the shape of the speaker is not circular, there are too many factors affecting the sound quality and sensitivity. This makes it very difficult and complicated to adjust the speaker. At this time, not only the vibration plate needs to be considered, but also the influence of the voice coil and elastic waves on the sound effect
[0004] The voice coil wires used in the prior art are basically pure copper wires or pure aluminum wires. Of course, the wires of the two materials have their own advantages and disadvantages, but when these two kinds of voice coil wires are used for non-circular speakers, their Sensitivity becomes lower and distortion is more serious

Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with the embodiments, so that those skilled in the art can implement it with reference to the description.

[0013] This application proposes an embodiment of a high temperature resistant voice coil wire for a loudspeaker, which at least includes a combination of aluminum, copper and manganese.

[0014] In the above embodiments, in parts by weight, there are 100 parts of aluminum, 60-62 parts of copper, and 3-4 parts of manganese.

[0015] Aluminum wire is lighter than copper wire and has high vibration efficiency, so it is bright and clear at high frequencies, but it is not durable; at the same time, the strength of aluminum wire itself is weak, and it is difficult to wind during processing; copper wire is heavy, and the center of the copper wire is suitable The surface is suitable for transmitting medium and low frequency signals, so the copper wire itself transmits signals unevenly, which ...

Abstract

The invention discloses a high-temperature-resistant voice coil wire for a loudspeaker, wherein the high-temperature-resistant voice coil wire at least comprises combination of aluminum, copper and manganese. Furthermore the high-temperature-resistant voice coil wire comprises the following components by weight: 100 parts of aluminum, 60-62 parts of copper, and 3-4 parts of manganese. According to the high-temperature-resistant voice coil, through improving the formula of a traditional voice coil wire, the added modifying metal effectively overcomes a defect of relatively low sensitivity in a non-circular loudspeaker. Furthermore, because of improvement function of the manganese, the voice coil wire has excellent high temperature resistance and fatigue resistance, so that the loudspeaker has certain saturation in full frequency bands, thereby greatly suppressing distortion of the loudspeaker.

Description

technical field [0001] The invention relates to an acoustic material, in particular to a high-temperature-resistant voice coil wire for a loudspeaker. Background technique [0002] The voice coil can be said to be the heart of the speaker, and it is also one of the important components of the speaker. After the voice coil conducts electricity, within the magnetic field, it is Fleming’s left-hand rule that produces movement and drives the drum paper to move, so the voice coil is the speaker’s core. The driving element is usually wound on a cylindrical frame made of paper and other materials with round enameled wires. The entire voice coil is wound in two or four layers. The purpose is to make both ends of the coil lead-out wires face the drum paper side, so The lead wire can be firmly welded on the drum paper. [0003] Traditional speakers are circular, but with the diversification of electronic product shapes, various speakers that can adapt to non-circular electronic produ...
