Abstract
The present disclosure provides a half in-ear earphone arranged with three
microphones, comprising a shell with an inner cavity, a sounding unit arranged in the
inner cavity and a plurality of noise-reduction microphones, the sounding unit divides
the inner cavity into a front acoustic cavity and a rear acoustic cavity, the noise
reduction microphones comprises a first noise-reduction microphone, a second noise
reduction microphone and a third noise-reduction microphone. The disclosure may
achieve an excellent noise reduction effect by locating the noise-reduction microphones
at three different positions. The earphone of the present disclosure adopts a half in-ear
structure, so a user may monitor a surrounding sound while allowing another party to
hear a clear call; and an ear pressure sensation is not existing, so a user may not feel
tired when calling for a long time. The present disclosure has simple structure and low
cost, and may effectively improve the sensitivity and accuracy of noise sampling by
adopting multiple noise-reduction strategies, which may improve user experience

FIG. 2
[0001] The present disclosure relates to the technical field of earphone and to a half in
ear earphone arranged with three microphones.
[0002] An earphone is a pair of conversion units, which may receive an electrical signal
sent by a media player or receiver, and convert it into audible sound waves by a
speaker close to ear. The earphone generally is detachable from the media player and
is connected to the media player with a plug. An advantage of the earphone is that a
user may listen to a sound alone without affecting others; the earphone may also isolate
a sound of surrounding environment, which is very helpful for a user in noisy
environment such as recording studio, bar, traveling, and sport.
[0003] A disadvantage of an earphone in prior art is that, when using the earphone to
make a call in an environment with high ambient noise, such as railway station, airport
and large shopping mall, the call may be affected.
[0004] At present, a plurality of strategies of earphone call in prior art for suppressing a
noise mainly include:
[0005] Dual-microphone (MIC) call noise reduction based on beamforming;
[0006] Single microphone (MIC) Al intelligent call noise reduction based on neural
network;
[0007] Dual-microphone (MIC) combined with bone conduction microphone (MIC) call
noise reduction.
[0008] A plurality of disadvantages of strategies of earphone call in prior art for
suppressing a noise are as follows:
[0009] Dual-microphone (MIC) call noise reduction based on beamforming may not
eliminate an ambient noise within a specified angle, and its ability to suppress wind
noise is limited;
[0010] Single microphone (MIC) Al intelligent call noise reduction based on neural
network may not suppress a vocal ambient noise that is louder than a user voice, and
its ability to suppress wind noise is limited;
[0011] Dual-microphone (MIC) combined with bone conduction microphone (MIC) call
noise reduction is less effective in suppressing high-frequency ambient noise, and its
price is relatively expensive.
[0012] Therefore, an existing technology needs to be improved.
[0013] The inventor found that an earphone in prior art has a problem that a call is
affected due to high decibel ambient noise during the call.
[0014] The present disclosure aims to alleviate or solve at least one of the above
mentioned problems to a certain extent. The present disclosure proposes a half in-ear
earphone arranged with three microphones, wherein including a shell with an inner
cavity, a sounding unit arranged in the inner cavity and a plurality of noise-reduction
microphones, the sounding unit divides the inner cavity into a front acoustic cavity and a
rear acoustic cavity, the noise-reduction microphones are located at three different
positions in the inner cavity.
[0015] In an embodiment, the noise-reduction microphones comprise:
[0016] a first noise-reduction microphone which is arranged in the front acoustic cavity;
[0017] a second noise-reduction microphone which is arranged at a top of the rear
acoustic cavity;
[0018] a third noise-reduction microphone which is arranged at a bottom of the rear
acoustic cavity.
[0019] In an embodiment, the shell comprises a front shell and a rear shell, and the
front shell is adaptively connected with the rear shell to form a half in-ear structure with
the inner cavity.
[0020] In an embodiment, a dust-proof net is arranged on the front shell, and the first
noise-reduction microphone is arranged between the sounding unit and the dust-proof
net.
[0021] In an embodiment, the first noise-reduction microphone, the second noise
reduction microphone, and the third noise-reduction microphone are audio input
components that connected in parallel connection.
[0022] The beneficial effects of present disclosure: in the present disclosure, the third
noise-reduction microphone is mainly responsible for collecting call sound, and the
second noise-reduction microphone is responsible for collecting external noise, when
the external noise is very loud, the third noise-reduction microphone may be called to
receive a data of user voice as a reference operation data to suppress an ambient
sound to eliminate the external noise; the first noise-reduction microphone is
responsible for collecting a noise in an ear canal, the data collected by the first noise
reduction microphone may be used to eliminate a wind noise, since the first noise
reduction microphone is in an ear canal, even when the wind noise is very loud, a call
quality may not be greatly affected. The earphone of the present disclosure adopts a
half in-ear structure, so a user may monitor a surrounding sound while allowing another
party to hear a clear call; and an ear pressure sensation is not existing, so a user may
not feel tired when calling for a long time; the present disclosure has a plurality of advantages including simple structure, low cost, and excellent noise-reduction effect, which may improve user experience.
