The switching of the noise reduction module 30 and the high-fidelity module 20 is realized through the switch module 400, so that the user can start the noise reduction function in a noisy environment and listen to the audio after noise reduction, and start the high-fidelity module in a quiet environment and listen to the HIFI audio without causing any conflict.
[0036] In this embodiment, the switch module 400 is a physical toggle switch, a touch switch, and a voice-controlled switch, one of which or a combination thereof realizes the control of the noise reduction module and the high-fidelity module, controls whether the noise reduction module 30 performs noise control, and controls whether the high-fidelity module 20 performs audio amplification.
[0037] Please combine Fig.10The switch module 400 includes a noise reduction switch 410 and a high-fidelity switch 420. The noise reduction switch 410 is used to control the noise reduction module 30 to be turned on and the high-fidelity module 20 to be turned off.

Preferably, the noise reduction switch 410 can be set as an ANC button, and the high-fidelity switch 420 can be set as a HIFI button. When the noise reduction module is started, press the ANC button to automatically turn off the HIFI module. When the HIFI module is enabled, press the HIFI button to automatically turn off the noise reduction module, thereby meeting the requirements of some people who have high requirements for sound effects and need to apply the noise reduction function in a specific environment. Its birth has broken the curse of noise reduction without HIFI and HIFI without noise reduction.
[0038] Please combine Figures 6 to 9 The Bluetooth headset also includes a shell 100 and an electroacoustic component 200 arranged in the shell 100, the electroacoustic component 200 includes a first electroacoustic element 210 and a second electroacoustic element 220, the first electroacoustic element 210 is arranged directly or partially directly opposite to the ear canal, the second electroacoustic element 220 is arranged offset from the ear canal, and is arranged at a distance from the first electroacoustic element 210, and the sound frequency of the first electroacoustic element 210 is greater than the sound frequency of the second electroacoustic element 220, so that the first electroacoustic element 210 emits a higher frequency sound, and adopts the principle of ergonomics to directly and quickly transmit it to the ear canal, so that the user has a stronger auditory impact on the high-frequency sound effect, the second electroacoustic element 220 emits a lower frequency sound, which is transmitted to the ear canal after being surrounded, so that the lower frequency sound effect forms a surround sound field, and the high frequency sound effect cooperates with the medium and low frequency sound effect to form a higher HIFI sound effect.
[0039] In this embodiment, the noise reduction module 30 is connected to the left channel 202 and the right channel 201 respectively. The left channel 202 and the right channel 201 are provided with an electroacoustic component 200 for playing audio.
[0040] In this embodiment, the first electroacoustic element 210 is a high-frequency speaker, which is used to output high-frequency sound effects, so that the user can get a stronger sense of auditory impact under high-frequency sound effects, and the second electroacoustic element 220 is a mid-low frequency speaker, which is used to output mid-low frequency sound effects, so that the surround effect formed by the mid-low frequency sound effects is better, giving the user an immersive auditory feast. Of course, in other embodiments, the combination of the first electroacoustic element 210 and the second electroacoustic element 220 can also be in other forms. For example, the first electroacoustic element 210 is a high-mid frequency speaker, and the second electroacoustic element 220 is a low-frequency speaker. The purpose is to make the first electroacoustic element 210 give the ear canal a stronger auditory impact, and the second electroacoustic element 220 forms a surround sound field effect, so as to obtain a higher HIFI sound effect, and provide good conditions for the HIFI of Bluetooth headsets.

The first electro-acoustic element 210 is formed in a smaller size and covers the ear canal directly. The first electro-acoustic element 210 is precisely aligned with the ear canal part of the human ear, so that the first electro-acoustic element 210 can form a stronger impact sound effect for the user. The second electro-acoustic element 220 is formed in a larger size and is misaligned with the ear canal to form a more divergent and perfect surround sound field sound effect. The impact sound effect and the surround sound field sound effect are coordinated to enhance the formation of better HIFI sound effect.
