Adjustable sub-vacuum earplugs

Abstract

The invention provides an adjustable sub-vacuum earplug and relates to the field of sound insulation devices. The earplug includes a sound-insulating shell, a sound-transmitting diaphragm, and an air pump; wherein: the sound-insulating shell has a cavity, and the sound-insulating shell is provided with a sound-transmitting hole, and the sound-transmitting hole communicates with the cavity; The sound-transmitting diaphragm is packaged on the sound-transmitting path of the sound-transmitting hole; the air extractor communicates with the cavity, and is used to extract or put back part of the gas in the cavity. The present invention simply adjusts the air density state in the earplugs and cooperates with the change of the tension of the sound-transmitting diaphragm, which can not only enhance the sound insulation and noise reduction effect of the earplugs for hearing protection, but also reduce the sound insulation and noise reduction effects of the earplugs to Guarantee the ability of the wearer to communicate, and switch between the two states of sound insulation and communication as needed.

Description

technical field [0001] The invention relates to the field of sound insulation devices, in particular to an adjustable sub-vacuum earplug. Background technique [0002] The main function of earplugs is to reduce the intensity of noise transmitted to the outer ear by preventing the transmission of sound waves in a noisy environment, so as to achieve sound insulation and noise reduction and protect hearing. In many construction work environments, operators not only need to wear earplugs to protect their own hearing, but also need to have effective communication skills to ensure the smooth completion of work and avoid safety accidents. However, while traditional earplugs block noise, they also block the ability of operators to obtain communication information and safety information through hearing, that is, it is impossible to switch between the two states of sound insulation and communication.

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: to overcome the unsatisfactory sound insulation effect and the lack of communication function of the existing earplugs, and to provide an adjustable sub-vacuum earplug, which can adjust the air density state in the earplug easily and cooperate with the sound transmission diaphragm. The change of tightness can not only enhance the sound insulation and noise reduction effect of the earplugs for hearing protection, but also reduce the sound insulation and noise reduction effect of the earplugs to ensure the wearer's ability to communicate, and switch between the sound insulation and communication states as needed
