Problems solved by technology

However, according to the existing technology, due to its symmetrical characteristics, circular speakers are relatively easy to design and adjust in terms of sound quality and sensitivity. However, when the shape of the speaker is not circular, there are too many factors that affect the sound quality and sensitivity. It 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 fatigue-resistant and high-temperature resistant voice coil wire, which at least includes a combination of copper, aluminum and palladium.

[0014] In the above embodiments, in parts by weight, there are 100 parts of copper, 33-34 parts of aluminum, and 2-3 parts of palladium.

[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, wh...

Abstract

The invention discloses an antifatigue high-temperature-resistant voice coil line which at least comprises combination of copper, aluminum and palladium. Furthermore, the antifatigue high-temperature-resistant voice coil line comprises the following elements by weight: 100 parts of copper, 33-34 parts of aluminum and 2-3 parts of palladium. According to the antifatigue high-temperature-resistant voice coil line, through improving the formula of a traditional voice coil line, introduced modifying metals effectively overcome a defect of relatively low sensitivity in a noncircular loudspeaker. Furthermore, because of improvement by the palladium, the voice coil line has excellent high temperature resistance and excellent fatigue resistance, so that a loudspeaker has certain saturation in full frequency bands, thereby greatly inhibiting loudspeaker distortion.

Description

technical field [0001] The invention relates to an audio material, in particular to a fatigue-resistant and high-temperature-resistant voice coil wire for a non-circular 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 loudspeakers are circular, but with the diversification of electronic product shapes, various loudspeakers that ca...
