♀柠檬没我萌你是我要找的那只蓝鲸么首先让我们来看看声音传导的部分原理。我们耳朵的外面(外耳)与中耳、内耳是不相通的,中间有一层鼓膜。声音会先传到鼓膜,鼓膜震动传到锤骨,接着锤骨捶打砧骨,砧骨被敲醒了之后,就通知镫骨:“快醒醒,有声音!”镫骨也被震醒了以后,声音才会传到内耳里面去。中耳的鼓室内还有两条小肌肉非常重要,分别为鼓膜张肌和镫骨肌,它们是为了防止锤骨和镫骨用力 ♀ lemon did not I Meng you are the blue whale I am looking for? Let us first take a look at part of the principle of sound conduction. The outside of our ears (outer ear) and the middle ear, inner ear is not the same, with a layer of tympanic membrane in the middle. The sound will be transmitted to the tympanic membrane first, and the tympanic membrane vibrates to the malleus, and then the malleus beats the incus. After the incus is awakened, the tarsal bone is informed: “wake up, sound!” After waking up, the sound will spread to the inner ear. There are two small muscles in the middle ear tympanum is very important, respectively, tympanic membrane and tarsal muscles, they are to prevent the malleus and stapes force
