Embodiment Construction

[0025] The following is a detailed description of the graphics:

[0026] figure 1 It shows the composition and layout of the electronic artificial throat according to an embodiment of the present invention, the electronic artificial throat includes a remote control switch 101, a wireless transmitting device 102, a wireless receiving device 103, a waveform generation and processing system 104, a power amplifier circuit 105, a microelectronic - Force conversion system 106 .

[0027] In use, the switch signal generated by the remote control switch 101 in response to the user's operation is sent to the wireless transmitting device 102 . The wireless transmitting device 102 wirelessly transmits the switching signal; the wireless receiving device 103 receives the wirelessly transmitted switching signal, and sends the received switching signal to the waveform generating and processing system 104 .

[0028] The waveform generation and processing system 104 includes a memory capable ...

Abstract

The invention relates to a remote switch type artificial electronic larynx; a switch (101) is separated from an equipment main body, the equipment main body is fixed at the neck part of a user, the switch (101) is arranged on the finger or in a pocket of the user; the equipment comprises a remote switch, wireless transmitting / receiving devices (102, 103), waveform generation and processing system(104, 10), a power amplifying circuit (105, 9) and a minitype electricity-power conversion system (106). The remote switch transmits a switch signal to the equipment main body wirelessly, after the equipment is started, the wave forms generated by the waveform generation and processing system are converted into an analog signal which is transmitted to the power amplifying circuit, and then the analog signal is converted into mechanical vibration by the electricity-power conversion system after being power-amplified, the vibration is applied to the neck part of a patient to generate glottis waves, the wave forms form voice outside the lips through the modulation of the tongue, nasal cavity, oral cavity, lips and the like.

Description

technical field [0001] The invention belongs to the field of voice rehabilitation for voice-deficit patients, and in particular relates to a design method of a remote control switch type electronic artificial larynx. Background technique [0002] Among the various means used by human beings to communicate, voice is the most basic, effective and important one. At present, there are hundreds of thousands of patients with laryngeal cancer and other serious laryngeal diseases in the world. In order to treat laryngeal diseases, they have to undergo laryngectomy. Lose the ability to use voice for language communication. Electronic artificial laryngos have been used for about 40 years as an external voice rehabilitation method for voice-deficit patients. The current electronic artificial larynx is designed in one piece. During use, the patient puts the artificial larynx against his own larynx, and manipulates the pulse generated by the control switch. The pulse is applied to the ...
