[0003] Currently, in esports, noise reduction control is typically achieved by first putting the headset on the player's ears and then manually pressing the noise reduction button on the headset casing to activate the noise reduction effect. However, manually pressing the noise reduction button on the headset casing to adjust the noise reduction requires significant adjustments to the position or posture of the hand to reach the button, which is inconvenient and can easily distract the player, thus affecting the performance of the game. In addition, this adjustment method is not intuitive and can easily lead to accidental touches during operation, which can easily lead to unnecessary changes in the noise reduction level or activation of other functions, thereby interfering with the player's normal user experience.

[0004] Therefore, it is necessary to design a novel noise reduction control device and system to overcome the above-mentioned defects. Utility Model Content

[0032] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the present invention is described in detail below with reference to the embodiments.

[0033] Certain terms are used throughout the specification and claims to refer to specific components. Those skilled in the art will understand that manufacturers may use different terms to refer to the same component. This specification and claims do not distinguish components by name, but rather by their functional differences. Throughout the specification and claims, the term "including" is open-ended and should be interpreted as meaning "including, but not limited to."

[0034] The present invention proposes a noise reduction control system, which includes headphones 2 and a noise reduction control device 1. The noise reduction control device 1 is communicatively connected to the headphones 2 to send a noise reduction level signal to the headphones 2 and instruct the headphones 2 to process the acquired ambient noise at a corresponding level.

[0035] Reference Figures 1 to 2 As shown, Figure 1 The following is a schematic diagram showing the structure of a noise reduction control device 1 according to an embodiment of the present invention. Figure 2 The present invention discloses a structural block diagram of a noise reduction control system according to an embodiment of the present invention.

[0036] The noise reduction control device 1 includes a housing 10, a touch control unit 11, a first interface 12, a second interface 13, and a first processing unit 14 (not shown). The first interface 12 is exposed from an opening of the housing 10 and is communicatively connected to the earphone 2. The second interface 13 is exposed from another opening of the housing 10 and is data-connected to a source device 3 (e.g., a PC). The source device 3 transmits the audio signal to the earphone 2 via the noise reduction control device 1. The touch control unit 11 is configured on the housing 10 to receive the user's touch operation. The first processing unit 14 is disposed in the housing 10. The first processing unit 14 is coupled to the first interface 12, the second interface 13, and the touch control unit 11, respectively. Specifically, when the user touches the touch control unit 11, the first processing unit 14 generates a corresponding noise reduction level signal based on the received touch operation; the first interface 12 sends the noise reduction level signal to the earphone 2 to instruct the earphone 2 to perform corresponding level processing on the received ambient noise.

[0037] In one embodiment, the noise reduction level signal includes at least a noise reduction off signal, a first-level noise reduction signal, a second-level noise reduction signal, and a third-level noise reduction signal. The present invention is not limited thereto. It is understood that in actual designs, more noise reduction levels may be preset to facilitate users to more finely adjust the noise reduction effect based on different ambient noise levels and personal preferences, thereby meeting the needs of different users and improving product applicability.

[0038] The first, second, third, and off noise reduction signals are configured to be sequentially triggered by touch operations. For example, in one embodiment, a user presses touch control 11 once to trigger the first noise reduction signal, then presses it again to switch to the second noise reduction signal. Continuing the same operation sequentially triggers the third and off noise reduction signals. However, the present invention is not limited to this. In this way, different noise reduction level signals are sequentially issued through simple and intuitive touch operations, eliminating the need for complex multi-step operations or memorizing different button combinations, resulting in improved intuitiveness and ease of use.

[0039] It can be seen that the noise reduction control device 1 proposed in the present invention exists independently of the main body of the earphone 2 in the form of an external device. Through intuitive and convenient touch operation, it can trigger different noise reduction level signals, instructing the earphone 2 to process the acquired ambient noise at the corresponding level, thereby improving the gaming listening effect. This effectively avoids the situation mentioned in the prior art where the user wears the earphone 2 and manually touches the noise reduction button on the earphone 2 shell to adjust the noise reduction, which requires a significant adjustment of the hand position or posture and is not intuitive to operate, thus causing accidental touches or interference with the game. The noise reduction control device 1 proposed in the present invention is reliable in operation and can provide a smooth operating experience, allowing users to freely and intuitively select the appropriate noise reduction level based on the current ambient sound level, and the usage scenarios are more diverse and convenient.

[0040] In one embodiment, the touch panel 11 includes a touch area 11S for receiving user touch operations. The touch area 11S is embedded in the surface 10s of the housing 10 of the noise reduction control device 1 to provide an intuitive and smooth touch experience. Furthermore, the touch panel 11 can utilize capacitive touch technology or resistive touch technology to receive user touch commands, but the present invention is not limited thereto.

[0041] Further preferably, the first interface 12 and the second interface 13 are respectively located on both sides of the shell 10 and are not coplanar with the touch area 11S. This helps to optimize the spatial layout of the noise reduction control device 1, improve the convenience of touch operation, and make it more convenient for users to connect or disconnect the source device 3 and the headphones 2, effectively avoiding interference or conflict between cables, and helping to ensure the stability of the transmission of the above-mentioned audio signals and noise reduction level signals.

[0042] In one embodiment, the noise reduction control device 1 further includes a plurality of light-emitting components, which are arranged on the housing 10 and coupled to the first processing unit 14. The first processing unit 14 is also used to control the number of light-emitting components that are lit to indicate the current noise reduction level, thereby providing visual feedback and intuitively displaying the current degree of noise reduction. Further preferably, the light-emitting components are embedded in the edge or center of the touch area 11S, so that when the user performs a touch operation, it not only triggers the change in the noise reduction level, but also provides a corresponding lighting effect to achieve instant visual feedback. In addition, in other preferred embodiments, the light-emitting components are directly embedded in the surface 10s or interior of the housing 10, and the light thereof can be displayed through the housing 10 to indicate the current noise reduction level while maintaining the neatness and smoothness of the noise reduction control device 1. The present invention is not limited to this.

[0043] In one embodiment, the first interface 12 is connected to the headset 2 in a wired or wireless manner, and the second interface 13 is connected to the source device 3 in a wired or wireless manner. Preferably, the first interface 12 is a Type-C interface, the headset 2 is connected to the Type-C interface by wire, and the second interface 13 is connected to the source device 3 in a wired manner. The present invention is not limited to this. In other embodiments, the wireless connection includes but is not limited to wireless communication technologies such as Bluetooth and Wi-Fi.

[0044] Further, if Figure 2As shown, in one embodiment, the headset 2 further includes a microphone 21, a transceiver unit 22, a second processing unit 23, and a speaker unit 24. The microphone 21 is used to receive ambient noise, and the transceiver unit 22 is coupled to the first processing unit 14 of the noise reduction device to receive a noise reduction level signal. The second processing unit 23 of the headset 2 is coupled to the transceiver unit 22. Based on the relationship between the noise reduction level signal and preset noise reduction parameters, the second processing unit 23 generates corresponding noise reduction parameters, thereby reducing the ambient noise received by the microphone 21. Specifically, the second processing unit 23 of the above-mentioned earphone 2 stores the correspondence between the noise reduction level signal and the noise reduction parameter. The second processing unit 23 determines the target noise reduction parameter based on the received noise reduction level signal and the correspondence. The second processing unit 23 is also used to generate an anti-phase sound wave opposite to the ambient noise sound wave based on the target noise reduction parameter to reduce the ambient noise received by the microphone 21. In addition, the second processing unit 23 is also configured to mix the played audio signal and the anti-phase sound wave to obtain a mixed audio signal, which is played through the speaker unit 24 of the earphone 2.

[0045] In summary, the noise reduction control device 1 proposed in the present invention exists independently of the main body of the earphone 2 in the form of an external device. The noise reduction control device 1 includes a housing 10, a touch control unit 11, a first interface 12, a second interface 13, and a first processing unit 14. The user performs simple and intuitive touch operations based on the current ambient noise. The first processing unit 14 generates a corresponding noise reduction level signal based on the received touch operation. The first interface 12 sends the noise reduction level signal to the earphone 2, instructing the earphone 2 to process the received ambient noise at a corresponding level, thereby improving the gaming listening experience. The operation is reliable and intuitive, allowing users to freely and intuitively select the appropriate noise reduction level based on the current ambient sound level, making the usage scenarios more diverse and convenient.
