The collar 202 is constructed and arranged to be worn around at least a portion of the user's neck, the collar 202 may be shaped as a circular arc as shown in fig. 1 and 2 so as to fit around the user's neck when worn by the user; this neck collar also can set up to square, and is similar with the neck collar of circular arc, and square neck collar is equipped with the opening to the uncomfortable sense of neck is tightened to the neck collar that can avoid the user to appear the neck collar to the user dress. The configuration of the collar 202 may be as shown in fig. 2, the collar 202 comprising two end portions (e.g. 2021 and 2022 in fig. 2), each end portion being provided with a respective microphone element 203, the configuration of each microphone element 203 being the same. The structure of each microphone element 203 will be described below with reference to fig. 2 and 3.
In one example, each microphone element 203 includes at least two microphones 2031, each microphone 2031 being aligned along a major axis of the end at which it is located; and is positioned in parallel opposition to the microphone 2031 provided at the other end to constitute a beamforming array. Each microphone element is located proximate to an inside of the neck collar, which is the side of the neck collar that is proximate to the neck of the user when the neck collar is worn.
Specifically, each microphone element 203 includes at least 2 microphones 2031, for example, as shown in fig. 2, 2 microphones 2031 are provided in each microphone element 203, it is understood that 3 microphones and 4 microphones can be provided in each microphone element 203, and the number of microphones 2031 in each microphone element 203 can be determined according to the application.

It is worth mentioning that the arrangement of the microphones in the microphone elements on each side makes the direction of the microphone elements listening to the sound source closer to the direction of the human ear listening to the sound source, thereby improving the listening effect of the microphone elements.
It will be appreciated that the face of the end of the neck collar 202 that is in direct contact with the skin of the user should not be provided with a microphone element 203 in order to better listen to the sound source.
In one example, the control portion 30 may be disposed on the neck collar 202, or may be disposed on the earphone line 201. As shown in fig. 4, the control unit 30 may include: a receiving module 301, a determining module 302 and a processing module 303.

The determining module 302 is specifically configured to: for each sound wave in the first sound, the following processing is performed: determining the sound source direction of the sound wave according to the time value of the sound wave received by each microphone 2031; determining the distance between the sound source of the sound wave and the microphone according to the sound wave intensity of the sound wave received by each microphone 2031; and if the sound wave direction belongs to a first direction and/or the distance is smaller than a preset threshold value, determining that the sound wave belongs to effective sound waves, otherwise, determining that the sound wave belongs to noise sound waves, wherein the first direction is the visual angle direction of the user.
As each microphone is arranged in the manner shown in fig. 3, the time value of sound wave received by each microphone is different, and the intensity of the same sound wave received by each microphone is different due to the different distance between the sound source and the microphone. For example, as shown in fig. 3, 3 microphone m1 and 3 microphone m3 receive sound wave S1 at time t1, and microphone m2 and microphone m4 receive sound wave S2 at time t 2; according to the time difference between t1 and t2, the sound source direction of the sound wave S1 can be determined, and the intensity of the sound wave received by m1, m3 m2 and m4 is different, so that the distance between the sound wave and the microphone can be determined. It will be appreciated that four or more microphones arranged in a circular or spherical array to form a beam-forming array provide signals that can be used to determine the direction from which sound is received using more sophisticated signal processing algorithms. Of course, each microphone employs a high-sensitivity digital microphone.
And if the sound wave direction belongs to a first direction and/or the distance is smaller than a preset threshold value, determining that the sound wave belongs to effective sound waves, otherwise, determining that the sound wave belongs to noise sound waves, wherein the first direction is the visual angle direction of the user. The preset threshold can be set according to practical application, and the first direction is a visual angle direction of a user, namely the first direction is a direction viewed by eyes of the user when the user wears the neck ring.
The processing module 303 amplifies the effective sound wave, attenuates the noise, thereby obtaining a second sound, and transmits the second sound to the sound amplification portion, which plays the second sound.
It is worth mentioning that the microphone is arranged on the neck ring, so that the microphone can intercept the sound source in the range of 180 degrees in front of the user, the interception range can be reduced, the unwanted sound on the side surface and the back surface is reduced, and the collection of unnecessary sound waves is avoided.
