Frederickson 及 Bryce 在1975年对一种含有二套部件的植入咽后壁与颈椎间的电子喉装置进行了实验研究。研究的目的有三:(1) 设计制造一种电子喉植入咽后壁与颈椎之间,是一种被动发声器,其电源由体外信号源经皮肤传导。(2) 以动物实验鉴定此装置的组织接受性、耐用性及发声能力。(3) 鉴定作为喉截除术后病人发声装置的应用价值。装置在体外的部分包括多脉冲振荡器及电 In 1975, Frederickson and Bryce conducted an experimental study of an electronic throat device with two sets of components implanted between the posterior pharyngeal wall and the cervical vertebra. The purpose of the study is threefold: (1) design and manufacture of an electronic throat implanted between the posterior pharyngeal wall and the cervical spine, is a passive sound generator, the power from the external signal source through the skin conduction. (2) animal experiments to identify the device’s tissue acceptability, durability and vocal ability. (3) Identify the value of the device as a human voice device after laryngectomy. The extracorporeal part of the device includes a multi-pulse oscillator and electrical
