Acoustic coupler and data transmission apparatus using the same
First Claim
1. An acoustic coupler comprising:
- a receive part housing having a first end and a second end;
a transmit part housing having a first end and a second end;
a coupling member mechanically coupling said receive part housing and said transmit part housing;
a first microphone fastened to the first end of said receive part and receiving an acoustic signal from a transmitter portion of a handset of a telephone when said acoustic coupler is set to said handset;
a first speaker fastened to the second end of said receive part and outputting an acoustic signal to an operator;
a second speaker fastened to the first end of said transmit part and outputting an acoustic signal to a receiver portion of the handset;
a second microphone fastened to the second end of said transmit part and inputting an acoustic signal from the operator; and

Abstract
An acoustic coupler for a data communication device with a housing having a receiver and a coupling member mechanically coupling the receive housing and the transmitter housing. The acoustic coupler also includes a first microphone as part of the receiver for receiving an acoustic signal from a transmitter portion of a handset of a telephone, when the acoustic coupler is set to the handset. A first speaker is fastened to the second end of the receive part and outputting an acoustic signal to an operator, with yet a second speaker being fastened receiver portion of the housing for outputting an acoustic signal to a receiver portion of the handset. A second microphone is fastened to another part of the receiver which is for inputting an acoustic signal from the operator, and a coupling circuit for electrically coupling the first microphone, the second microphone, the first speaker and the second speaker to a data transmission apparatus. This arrangement allows for a more reliable connection of a data transmission device to the communication medium, be it radio or wired.
