The using method comprises the following steps: the top end of the vibrating piece 2 is flatly stuck and tightly stuck to the lower pharynx part of the esophagus (the upper opening of the esophageal duct) at the head and neck. The optimum sound transmission point is different for different people because of different total laryngectomy operation methods, the size of postoperative scars, whether the hyoplastron is cut off or not, or the change of muscle tissues after radiotherapy, and different neck muscles. Generally, the muscles are thinnest at the upper end of the neck and on both sides of the upper mouth of the esophagus, and the part of the esophagus closest to the skin is the best. If the neck tissue scar is hard and solid after radiotherapy, a sound transmission point can be found out on the chin at the bottom of the mouth (under the mouth); finding the best sound transmission point, the vibrating piece 2 is flat and tight, so that the vibration sound is sealed by the surrounding skin of the vibrating piece 2, the vibration sound is not transmitted out of the neck and only can be transmitted into the upper mouth of the esophagus, and the sound can be generated through the resonance and the sound amplification of the oral cavity; the mouth cavity plays a great role when the device is used, not only is like a normal person to speak out a word which the person wants to speak according to the change of the mouth shapes such as lips, teeth, tongue and the like, but also plays a role in resonance and diffusion like a loudspeaker, so when the device is used for speaking, the mouth shape can be optimally widened, the mouth shape is large, and the emitted volume is also large; when the device is used for speaking, the habit of speaking during normal persons in the past must be changed, the mode of using lung gas to drive vocal cords cannot be used any more (actually, the vocal cords can drive, and only gas can be uselessly sprayed out of a tracheostoma), and the disturbance sound cannot be generated by the rush of the esophageal gas. Either lung qi or esophageal qi can seriously interfere with the pronunciation of the electronic larynx. Can only breathe normally naturally at ordinary times, because the user can talk only by changing the mouth shape; when the pronunciation is practised, the switch button is pressed by the thumb, and the mouth is opened to pronounce, when the user is first to learn, the user opens the big mouth and presses the switch to pronounce an o character. The user can give out the words you want to speak according to the change of the mouth shape, when the user learns the words at first, such as o, wo, babble, 1, 2 and 3, and when the user speaks a word and presses the word, the user immediately releases the switch button after speaking the word, and the switch button and the speech are required to be synchronously operated. During practice, the frequency and the volume are continuously adjusted to find a frequency segment and a volume segment which are suitable for the user. After the habit is used, the speech speed can be accelerated, the frequency is adjusted again, and the frequency section under the ordinary speech speed is found.
