The preferred embodiments of the present application are provided in the accompanying drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.

[0025] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present application. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0026] For the description of this application, non-limiting Figure 1 The marks “upper”, “lower”, “left” and “right” shown in the figure are used to facilitate the understanding of the embodiment and are not intended to limit the present application.

[0027] Figure 1-Figure 9 The embodiment of the headset of the present application for industrial high-noise environment is shown, including a back hanger 1, a right ear hanger 2, a left ear hanger 3, a left face-attaching component 4, a right face-attaching component 5 and a stick microphone component 6. The back hanger 1 is connected between the right ear hanger 2 and the left ear hanger 3, the left face-attaching component 4 is connected to the left ear hanger 3, the right face-attaching component 5 is connected to the right ear hanger 2, and the stick microphone component 6 is connected to the left face-attaching component 4 or the right face-attaching component 5; a power supply component 21 is arranged in the right ear hanger 2, an electric control board 31 is arranged in the left ear hanger 3, and the power supply component 21 and the electric control board 31 are connected by a connecting line 32 is electrically connected, and the connecting line 32 is passed through the rear hanging 1; bone conduction speakers are arranged in the left face-stick component 4 and the right face-stick component 5, and the stick microphone component 6 has a accommodating cavity, a bone conduction microphone 61 is arranged at the upper part of the accommodating cavity, and an air conduction microphone 62 is arranged at the lower part of the accommodating cavity, the bone conduction speaker, the bone conduction microphone 61 and the air conduction microphone 62 are electrically connected to the electronic control board 31, the bone conduction microphone 61 is used to pick up external sounds in the first noise environment, and the air conduction microphone 62 is used to pick up external sounds in the second noise environment.

[0028] In some embodiments, the ambient noise in the first noise environment is greater than 90dB. In this application, an air conduction microphone 62 and a bone conduction microphone 61 are set in the stick microphone assembly 6. The bone conduction microphone 61 is used to pick up external sounds in the first noise environment, that is, when the ambient noise is greater than 90dB, the voice information of the personnel is collected through the bone conduction microphone 61, and the air conduction microphone 62 is used to pick up external sounds in the second noise environment, that is, when the ambient noise is less than or equal to 90dB, the air conduction microphone 62 is used to collect the voice information of the personnel, thereby ensuring that the voice information of the personnel can be clearly picked up in different environments. In this way, accurate information exchange between personnel in industrial high-noise environments is ensured.

[0029] The ambient noise in the second noise environment is less than or equal to 90dB. When the ambient noise is less than or equal to 90dB, the voice information of the personnel can be better collected through the air conduction microphone 62. It also avoids the distortion of the voice picked up by the bone conduction microphone 61. When the ambient noise is greater than 90dB, the external ambient noise will cause greater interference to the air conduction microphone 62, which makes it difficult for the air conduction microphone 62 to pick up voice information and it is difficult to obtain voice information stably. Therefore, at this time, the bone conduction microphone 61 is used to pick up voice information to ensure accurate communication of information between personnel in the industrial high-noise environment.

[0030] In some embodiments, Figure 2 As shown, an auxiliary microphone 33 is provided in the left ear hook 3, and the auxiliary microphone 33 is electrically connected to the electric control board 31. The auxiliary microphone 33 is used to pick up external environmental noise. The external environmental noise is picked up by the auxiliary microphone 33, and the picked up environmental noise is sent to the electric control board 31. The electric control board 31 determines whether the external environment is the first noise environment or the second noise environment according to the picked up environmental noise. Then the air conduction microphone 62 or the bone conduction microphone 61 is controlled to pick up voice information.

[0031] In some embodiments, Figure 2 and Figure 3 As shown, the left face-attaching component 4 is connected to the stick-microphone component 6, and the stick-microphone component 6 includes an extension 63 and a receiving component 64. One end of the extension 63 is connected to the left face-attaching component 4, and the other end is connected to the receiving component 64. The middle of the extension 63 has a strip hole 631. The material inside the extension 63 is titanium wire, and the material outside is silicone or plastic. In this way, the stability of the structure is achieved, ensuring that the stick-microphone component 6 is not easy to turn over, ensuring the face-attaching effect. At the same time, there is a certain flexibility of eversion, ensuring that the headset can adapt to different human face structures.

[0032] In some embodiments, Figure 4 As shown, the accommodating member 64 includes a stick microphone shell 641 and a stick microphone cover 642. The stick microphone shell 641 and the stick microphone cover 642 are enclosed to form an accommodating cavity. Silicone can be filled in the accommodating cavity to bond the bone conduction microphone 61 and the air conduction microphone 62 and play a waterproof role. A partition 643 is provided in the accommodating cavity. The partition 643 divides the accommodating cavity into a first cavity 6431 and a second cavity 6432. The bone conduction microphone 61 is provided in the first cavity 6431, and the air conduction microphone 62 is provided in the second cavity 6432. The first cavity 6431 is located at the upper part, and the second cavity 6432 is located at the lower part, thereby avoiding the mutual influence of the air conduction microphone 62 and the bone conduction microphone 61, and ensuring the stability of picking up voice information.

[0033] In some embodiments, Figure 5-Figure 8As shown, a connector 644 is provided in the container 64. The connector 644 includes an air conduction connector 6441, a bending portion 6442 and a bone conduction connector 6443 which are connected in sequence.

The bone conduction connector 6443 is two plate-like structures parallel to each other, one for mounting the bone conduction connector 6443 and the other for supporting the connector 644. An air conduction microphone 62 is provided inside the air conduction connector 6441. The air conduction microphone 62 is located between the air conduction connector 6441 and the partition 643. The air conduction microphone 62 faces a direction away from the extension member 63. There is a gap between the partition 643 and the inner wall of the container 64. The bending portion 6442 extends in a direction away from the air conduction microphone 62 and is located at the gap. An air hole is provided at the bottom of the container 64 opposite to the air conduction microphone 62 to facilitate the conduction of sound. The bone conduction connection part 6443 is disposed in the first cavity 6431, and a bone conduction microphone 61 is disposed on the bone conduction connection part 6443, and the bone conduction microphone 61 faces the direction of the microphone cover 642. The air conduction microphone 62 and the bone conduction microphone 61 are easily fixed by the connection member 644, and the stability of the installation of the air conduction microphone 62 and the bone conduction microphone 61 is ensured. A gasket 65 is also disposed between the air conduction microphone 62 and the accommodating member 64, and the gasket 65 is used to ensure the stability of the connection member 64.
