Speaker with double voice coils

Abstract

The invention relates to a speaker with double voice coils, which comprises a vibrating membrane, a first voice coil, a second voice coil, and a magnetic driver. The first voice coil is combined with the vibrating membrane, and receives a first signal so as to generate a first magnetic force; the second voice coil is combined with the vibrating membrane and receives a second signal so as to generate a second magnetic force; moreover, the magnetic driver generates a fixed magnetic field so as to interact with the first magnetic force and the second magnetic force, and lead the first voice coil and the second voice coil to drive the vibrating membrane together.

Description

technical field [0001] The invention relates to a loudspeaker, in particular to a loudspeaker with double voice coils. By simultaneously inputting two kinds of signals to the corresponding voice coils, the loudspeaker can reflect the sound output of signal superimposition. Background technique [0002] With the ever-changing market demand, various electronic products are developing more rapidly. Among them, earphones that people wear and enjoy music are also developing in multiple directions, both in terms of industrial design and functions. All earphones have the function of noise cancellation, the purpose is to eliminate the noise interference from the outside world, so as to provide the wearer with clear music. However, among the main parts of the earphone, the speaker is one of the important components of the sound output, and it is also the output of the noise canceling earphone. Necessary building blocks for noisy signals. [0003] Such as figure 1 Shown is a section...

AI Technical Summary

Problems solved by technology

Generally speaking, the speaker 1 is often used on earphones to convert sound and provide music and other sound signals to the wearer of the earphone. As shown in the figure, the voice coil 2 adopts a double-layer winding method with a single wire. It is used to increase the frequency response and power of the speaker 1, but the voice coil 2 can only receive a single sound signal, so that the vibration film 4 reflects only one effect, so the speaker 1 still needs to pass through a digital chip when it is used on the noise canceling earphone Only by integrating and processing sound signals can we achieve the goal of noise cancellation. However, the cost of digital chips is not low, and the internal complex circuits need to be completed through careful calculation and arrangement, which substantially increases the sales cost of noise-canceling headphones. Conducive to market competition

[0004] This shows that above-mentioned existing loudspeaker obviously still has inconvenience and defect in structure and use, and demands urgently further improving

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem
