Electronic speech aid device |
摘要 |
An electronic speech aid device to be worn by a wearer, includes an ear plug, a micro-microphone, a processing module and a micro-speaker. The ear plug is to be inserted into an acoustic meatus of the wearer. The micro-microphone is disposed on the ear plug for receiving a larynx sound, which results from attempt by the wearer to speak, from a larynx of the wearer through the acoustic meatus and for converting the larynx sound into a larynx-sound signal. The processing module is electrically connected to the micro-microphone for receiving and processing the larynx-sound signal to output a voice signal. The micro-speaker is electrically coupled to the processing module for receiving and outputting the voice signal. |

1. An electronic speech aid device adapted to be worn by a wearer, comprising:
an ear plug adapted to be inserted into an acoustic meatus of the wearer; a first micro-microphone disposed on said ear plug for receiving a larynx sound, which results from attempt by the wearer to speak, from a larynx of the wearer through the acoustic meatus and for converting the larynx sound into a larynx-sound signal; a processing module electrically connected to said first micro-microphone for receiving the larynx-sound signal therefrom and for processing the larynx-sound signal to output a voice signal, wherein said processing module includes a filter for eliminating at least one of a feedback signal and a noise in a signal associated with the larynx-sound signal, said filter including a digital signal processing circuit and a feedback signal canceling circuit; a user-operable interface including an analog/digital selecting switch operable to switch between an analog output enabling mode and a digital output enabling mode; a first micro-speaker electrically coupled to said processing module for receiving the voice signal and for outputting the voice signal; and wherein said digital signal processing circuit filters the signal associated with the larynx-sound signal in a digital format when said analog/digital selecting switch is in the digital output enabling mode, and said feedback signal canceling circuit eliminates the feedback signal in the signal associated with the larynx-sound signal in an analog format when said analog/digital selecting switch is in the analog output enabling mode. |
