Headset device with speakers, signal processing method and analysis system thereof

A signal processing method, adapted to a headset device with speakers, comprising:

• receiving a first ambient sound adjacent to a human ear by a first sound receiving assembly, and converting the first ambient sound into a first captured signal by the first sound receiving assembly;
• transmitting the first captured signal to a signal processing module in a speaker assembly;
• sequentially performing transfer function calibration signal processing and inversion signal processing on the first captured signal by the signal processing module, wherein the transfer function calibration signal processing calibrates the first captured signal through a transfer function with respect to a transmission distance of an output sound from the speaker assembly to the human ear;
• and
• providing a processed first captured signal to an output module of the speaker assembly for outputting toward the human ear.

A signal processing method, adapted to a headset device with speakers, comprising:

• transmitting an audio sound to a human ear by the output module of a speaker assembly;
• receiving the audio sound and a first ambient sound adjacent to the human ear by a first sound receiving assembly, and converting the audio sound and the first ambient sound into a first captured signal by the first sound receiving assembly;
• eliminating an audio signal in the first captured signal;
• transmitting the first captured signal with the audio signal eliminated to a signal processing module in the speaker assembly;
• sequentially performing elimination signal processing, transfer function calibration signal processing, and inversion signal processing on the first captured signal with the audio signal eliminated by the signal processing module, wherein the transfer function calibration signal processing calibrates the first captured signal through a transfer function with respect to a transmission distance of an output sound from the speaker assembly to the human ear;
• and
• providing a processed captured signal to an output module of the speaker assembly for outputting toward the human ear.

An analysis system, adapted to a headset device with speakers, comprising:

• a measurement module having an artificial head and a sound receiving assembly, the sound receiving assembly configured on the artificial head, the headset device with speakers configured on the artificial head, a speaker assembly corresponding to the sound receiving assembly;
• a sound output module, electrically connected to the speaker assembly;
• a sound receiving module, electrically connected to the sound receiving assembly;
• and
• a detection assembly, electrically connected to the sound output module and the sound receiving module;
• wherein, the detection assembly outputs a first sound signal;
• the first sound signal is transmitted to the speaker assembly by the sound output module;
• the speaker assembly outputs a first sound;
• the first sound is transmitted through the air to the sound receiving assembly and is received as a second sound;
• the sound receiving assembly converts the second sound into a second sound signal;
• the second sound signal is transmitted to the detection assembly by the sound receiving module;
• the detection assembly calculates a transfer function relationship between the first sound signal and the second sound signal, wherein the transfer function relationship is configured to be applied to a calibration unit of a signal processing module in the speaker assembly to compensate for a playback influence arisen from a transmission distance between the speaker assembly and a human ear.
