Denture-type Electrolarynx is being watched recently because it is easy to control the pitch and volume and it is not exposed on the outside. This system consists of three pars. The first is the Oral-Unit part, which contains a receiver, a loud speaker, and a rechargeable battery. The others are the Transmitter St Control-Unit Part, and the Charging-Unit part. We have newly developed the Korean Denture-type Electrolarynx : NeoVox. That system is designed considering low-power consumption, wireless charging system, small size and the speaker emphasizing low-frequency. So that the laryngectomees feel comfortable to use it and speak naturally.
