Earphone capable of protecting hearing of ears

Abstract

The invention relates to the technical field of earphones, in particular to an earphone capable of protecting hearing of ears, which comprises a voltage stabilizing module, a volume limiter, an audio amplification module, an audio feedback module, a volume control module and a loudspeaker. The output end of the voltage stabilizing module is connected with the volume limiter, the audio amplification module and the audio feedback module through transmission lines; a capacitor C1 is arranged at the output end of the volume limiter, the end, away from the volume limiter, of the capacitor C1 is electrically connected with the input end of the audio amplification module and the input end of the audio feedback module, a capacitor C5 is arranged on one side of the audio amplification module, and surrounding sound can be conveniently collected through the arrangement of the volume limiter. Through the arrangement of the audio amplification module and the audio feedback module, the volume of over-high or over-low sound can be conveniently adjusted, so that an operator can hear clearly and conveniently, and meanwhile, the sound can be pressed down instantly when the sound is suddenly larger in decibel during use, so that the ears are effectively protected, and the hearing is protected.

Description

technical field [0001] The invention relates to the technical field of earphones, in particular to an earphone for ear protection. Background technique [0002] In industrial work environments, noise (eg vibrations) generated periodically or continuously, for example from the mechanical handling of machines (eg drilling) or alarm speakers, may be a common phenomenon. Typically, at low and high frequencies, this can be detrimental to workers' ears and can potentially cause vibration-induced hearing loss or hearing impairment during short- or long-term exposures. Potential hearing impairment concerns are commonly found in manufacturing and other industrial facilities, but can also arise in military settings, airport settings, entertainment venues, and a variety of other environments that involve exposure to high levels of noise or vibration. In general, hearing damage due to prolonged exposure to vibration (especially at low frequencies) may go unnoticed in the short term, bu...
