Abstract

The invention discloses an acoustic switch and an in-ear loudspeaker. The acoustic switch comprises a shell, a magnetic ring, a sealing piece, a magnet and a coil, wherein the shell is provided with a gas flow channel which communicates the interior and the exterior of the shell; the magnetic ring is fixed relative to the shell, and the gas flow channel passes through the magnetic ring; the sealing piece comprises a moving part and an elastic part connected between the moving part and the shell, and at least part of the moving part is made of a magnetic conductive material; the magnet and the shell are relatively fixed, and the magnet and the magnetic ring are located on the two sides of the moving part respectively; the coil is electrified to generate a magnetic field for polarizing the moving part; and the moving part is provided with a first position and a second position, the moving part is in magnetic attraction with the magnetic ring to close the gas flow channel at the first position, the moving part is in magnetic attraction with the magnet to open the gas flow channel at the second position, the coil drives the moving part to be switched between the first position and the second position through the magnetic field generated by electrification of the coil. The acoustic switch provided by the invention is beneficial to realizing miniaturization, and is more energy-saving and low in heat productivity.

Description

technical field [0001] The invention relates to an acoustic device, in particular to an acoustic switch and an ear speaker. Background technique [0002] An in-ear speaker is an acoustic device that is inserted into the human ear canal when in use, such as in-ear headphones and hearing aids. In-ear speakers can isolate the ear canal from the outside world, making the ear canal form 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 ears to swell, and the voice of the wearer to feel hollow and uncomfortable or too loud, which is not conducive to improving the comfort of use of the in-ear speaker. [0003] In the prior art, in order to eliminate the ear blocking effect, a channel connecting the ear canal and the outside world is often provided on the in-ear speaker, but this method will reduce the noise reduction effect and sound quality perfor...
