Problems solved by technology

[0003] And existing earphone generally installs a loudspeaker in the casing, and this loudspeaker can only be a kind of in low-frequency loudspeaker, mid-frequency loudspeaker and high-frequency loudspeaker.
The single-frequency earphone can only emit a single-frequency sound wave, so that high- and low-frequency complementarity cannot be realized at all, and the three-dimensional effect of the sound is poor, and the user experience is poor.

Abstract

The disclosure relates to an earphone. The earphone includes a housing, a first speaker located in the housing and configured to play a first sound in a high frequency range, and a second speaker located in the housing and configured to play a second sound in a low frequency range or a middle frequency range. The first speaker includes a thermoacoustic device unit including a sound wave generator including carbon nanotube structure. The second speaker is an electric loudspeaker, electromagnetic speaker, or capacitive speaker.

Description

technical field [0001] The invention relates to an earphone, in particular to an earphone based on thermal sound generation. Background technique [0002] Generally, speaker devices can be divided into low-frequency speakers, mid-frequency speakers and high-frequency speakers according to the sound range played. Among them, the low-frequency speaker can play low-frequency sound waves below 300Hz, the mid-frequency speaker can play intermediate-frequency sound waves from 300Hz to 2KHz, and the high-frequency speaker can play high-frequency sound waves above 2KHz. [0003] And existing earphone generally installs a loudspeaker in the casing, and this loudspeaker can only be a kind of in low-frequency loudspeaker, mid-frequency loudspeaker and high-frequency loudspeaker. The single-frequency earphone can only emit a single-frequency sound wave, so that high and low audio complementation cannot be realized at all, and the three-dimensional effect of the sound is poor, and the u...
