Description

说明书发明名称：具有听力保护功能的婴幼儿车技术领域 Instruction manual Title: Infant car with hearing protection technology

[0001] 本实用新型涉及生命健康领域，尤其涉及一种具有听力保护功能的婴幼儿车。 [0001] The present invention relates to the field of life and health, and in particular to a baby carriage with hearing protection function.

背景技术 Background technique

[0002] 人们生活的环境经常会产生猛烈的环境噪音，例如摇滚音乐声、汽车喇叭声、轮船鸣笛声、炮竹声以及打雷声等。一般地，人们长期生活在 90dB以上的噪声环境中，会影响听力。如果突然暴露在高达 120dB以上的噪声环境中，人们耳膜会破裂出血而遭受损害，导致双耳失去听力。因此，人们需要对避免长期生活在噪音较大的环境下，对于婴幼儿的听力保护显得尤其重要。人们采用耳塞塞入耳朵内或者将防噪保护套佩戴在耳廓外对听力进行保护。然而，由于婴幼儿的耳朵较小，不方便佩戴且容易脱落，因而耳塞或者防噪保护套不能有效对婴幼儿听力进行保护，致使婴幼儿听力遭受外界环境噪音的损伤，从而影响婴幼儿的听力和身心健康。婴幼儿车是供婴幼儿玩耍或睡觉的护理装置，然而现有的婴幼儿车不具有保护婴幼儿听力的功能，因此不能保护婴幼儿听力而避免遭受外界环境噪音对婴幼儿听力造成伤害。 [0002] The environment in which people live often produces violent environmental noise, such as rock music, car horns, ship whistle, gunfire, and thunder. In general, people who live in a noise environment above 90 dB will affect their hearing. If suddenly exposed to a noise environment of more than 120dB, people's eardrum will rupture and suffer damage, resulting in hearing loss in both ears. Therefore, people need to avoid long-term life in a noisy environment, especially for the hearing protection of infants and young children. People use earplugs to put them in their ears or wear a noise-proof protective cover outside the auricle to protect them. However, since the ear of the infant is small, it is inconvenient to wear and it is easy to fall off, the earplug or the noise-proof protective cover can not effectively protect the hearing of the infant, and the hearing of the infant is damaged by the external environmental noise, thereby affecting the hearing of the infant. And physical and mental health. Infant cars are nursing devices for infants to play or sleep. However, existing infant cars do not have the function of protecting the hearing of infants and young children, so they cannot protect the hearing of infants and children from external environmental noises.
