Problems solved by technology
[0005] Due to the fatigue limit of the shrapnel, it is easy to deform or even break when it is used for a certain period of time or when the displacement is too large, which will affect the normal operation of the acoustic switch and is not conducive to ensuring the reliability and service life of the acoustic switch.

The invention discloses an acoustic switch and an in-ear loudspeaker. The acoustic switch comprises a shell, a first magnetic conductive block, a second magnetic conductive block, a motion assembly and a coil. The first magnetic conductive block and the second magnetic conductive block are both arranged in the inner cavity, the first magnetic conductive block and the second magnetic conductive block are oppositely arranged, an interval space is formed between the first magnetic conductive block and the second magnetic conductive block, and a magnetic conductive loop is formed among the first magnetic conductive block, the shell and the second magnetic conductive block; the moving assembly is movably arranged in the inner cavity and comprises a magnet arranged on the outer side of the first magnetic conductive block and a first magnetic conductive plate arranged at one end of the magnet, magnetic poles of the magnet are distributed in the moving direction of the moving assembly, and at least part of the first magnetic conductive plate is located in the interval space; the coil is arranged outside the first magnetic conductive block in a sleeving mode and drives the moving assembly to be switched between the first position and the second position after being powered on. According to the acoustic switch, on-off can be achieved, an elastic piece does not need to be arranged, only the coil needs to be powered on when the position is switched, and more energy is saved.
Description
technical field [0001] The present invention relates to an acoustic device, in particular to an acoustic switch and an in-ear speaker. Background technique [0002] An in-ear speaker is an acoustic device that is inserted into the human ear canal during use, such as in-ear headphones and hearing aids. In-ear speakers can isolate the ear canal from the outside world, so that the ear canal forms a relatively closed space, so its noise isolation effect and acoustic performance are excellent. However, the closed ear canal will produce an ear-blocking effect, causing the wearer's ear to swell, feel that the voice he speaks is hollow and uncomfortable, or is too loud, which is not conducive to improving the comfort of the in-ear speaker. [0003] In the related art, in order to eliminate the ear blocking effect, a channel connecting the ear canal and the outside world is often opened on the in-ear speaker, and an acoustic switch is provided in the in-ear speaker, and the acoustic...
