PURPOSE:To enable a speaker to hear his or her voice of quality close to that when other people hear it by sending the source voice of the speaker directly to his or her ear by a dish type self-voice hearing device consisting of a series of a sound collection parts, a sound conduction part and a sound transmission part which have bottom plates and side plates respectively. CONSTITUTION:The dish type self-voice hearing device consists of three parts, i.e. the sound collection part 1, sound conduction part 2 and sound transmission part 3, which have the bottom plates A and side plates B respectively. When this device is used, the sound collection part 1 and sound conduction part 2 are opened and held at a constant angle of 70 - 90 deg. so that a sound is reflected efficiently and the sound conduction part 2 and sound transmission part 3 are opened at a constant angle of 150 - 180 deg. so that the sound flows naturally and the device is held naturally. In this state, the sound collection part 1 is held before the mouse at a slight interval, the end of the sound transmission part 3 is set covering the ear of the speaker, and the device is used while held like a receiver. Consequently, the speaker can hear his or her voice which is reflected and collected physically simultaneously with voicing and has quality close to that when other people hear. |
