Abstract
The invention provides an earphone and a set of earphones. The earphone includes a processing circuit and a filtering module. The processing circuit acquires a first speech signal and performs a pre-processing operation on the first speech signal to generate a second speech signal. The filtering module includes high-pass, low-pass, and band-pass filters. The processing circuit is further configured to: receive first, second, and third signals respectively from the high-pass, low-pass, and band-pass filters; perform a noise reduction operation on the second and third signals to generate a fourth signal; and perform a signal synthesis operation on the first and fourth signals to synthesize the first and fourth signals to form an output speech signal.
