Description

Earmuffs with intelligent recognition and selective noise cancellation capabilities.

This invention relates to an earmuff device, and more particularly to an earmuff device with intelligent recognition and selective noise cancellation capabilities.

Most existing active noise-canceling headphones use full-band noise cancellation technology, which cannot effectively distinguish between sound sources that should be retained and those that should be eliminated. This design may make it difficult for users to perceive warning sounds in their environment during daily use, such as vehicle horns or alarms, leading to safety concerns. Furthermore, if users wish to retain human voice conversations or alert sounds, current products lack the ability to selectively enable or intelligently adjust these sounds. In addition, current technology is insufficient in dynamic adaptability and sound recognition capabilities, failing to provide differentiated processing for different environmental conditions.

Therefore, it is necessary to propose a device that can identify the type of ambient sound and selectively filter and control it, so as to balance noise reduction effect and environmental awareness.

Therefore, the purpose of this invention is to provide an earmuff device with intelligent recognition and selective noise reduction functions to solve the problems of learning technology.

The invention addresses the problems of learner technology by providing an earmuff device with intelligent recognition and selective noise reduction capabilities, comprising: an earmuff body; a pair of microphones electrically connected to the earmuff body for collecting external sounds; a pair of audio processing modules electrically connected to the microphones and the earmuff body for analyzing the external sounds acquired by the microphones; and a noise reduction unit electrically connected to the audio processing modules for performing noise reduction processing based on the processing results of the audio processing modules.

In one embodiment of this invention, an earmuff device with intelligent recognition and selective noise cancellation is provided, and a control unit is electrically connected to the audio processing module.

In one embodiment of this invention, an earmuff device with intelligent recognition and selective noise cancellation is provided, wherein the control unit is a button.

The technology employed in this invention provides an earmuff device with intelligent recognition and selective noise reduction capabilities that conditionally filters and reduces sound noise.

The following description, based on Figures 1 and 2, illustrates the implementation of this invention. This description is not intended to limit the implementation of this invention, but rather to provide one example of its implementation.

As shown in Figure 1, an earmuff device 100 with intelligent identification and selective noise reduction function in one embodiment of this invention includes: an earmuff body 1; a pair of microphones 2 electrically connected to the earmuff body 1 for collecting external sound; a pair of audio processing modules 3 electrically connected to the microphones 2 and the earmuff body 1 for analyzing the external sound acquired by the microphones 2; and a noise reduction unit 4 electrically connected to the audio processing modules 3 for performing noise reduction processing based on the processing result of the audio processing modules 3.

According to an embodiment of the present invention, an earcup device 100 with intelligent recognition and selective noise cancellation functions collects external 360-degree sound field signals and performs direction determination through microphones 2, such as MEMS microphone arrays, disposed on the left and right sides of the earcup body 1. Preferably, the microphones 2 are positioned on the outside of the paired earcups to achieve good sound pickup. The collected audio information is transmitted to an audio processing module 3, which uses, for example, a built-in Edge AI processor equipped with a sound classification model to analyze the collected audio information. This allows the module to identify human voices, vehicle sounds, alarm sounds, and background noise, and to customize which sound types to retain or eliminate as needed. Based on the classification results, the noise reduction unit 4 dynamically adjusts the filtering range of the noise reduction circuit, such as preserving the human voice frequency band while suppressing low-frequency noise from the subway, thereby improving the personalized experience and safety.

As shown in Figure 2, in an embodiment of the present invention, the earmuff device 101 with intelligent recognition and selective noise reduction functions further includes a control unit 5, which is electrically connected to the audio processing module 3.

As shown in Figure 2, in an embodiment of the present invention, an earmuff device 101 with intelligent recognition and selective noise reduction functions, wherein the control unit 5 is a button.

Through the control unit 5, users can easily control the audio processing module 3 to freely control the types of audio they wish to retain or delete.

With the above structure, an earmuff device with intelligent recognition and selective noise reduction function can be provided to conditionally filter and reduce noise of sound.

The above description and explanation are merely illustrative examples of the preferred embodiments of this invention. Those skilled in the art may make other modifications based on the scope of the patent application as defined below and the above explanation, but such modifications shall still be within the spirit of the invention and the scope of the claims of this invention.
