| Abstract: |
This invention involves a headset for use with a cellular telephone. The headset comprises an acoustical earpiece assembly adapted for the acoustical transmission of sound to the ear, a device for mounting the earpiece assembly on the head in a position adjacent an ear of a person wearing the headset, and a flexible acoustical receiving tube having an upper end connected to the earpiece assembly and a lower end attached to an acoustical receiving cup. The headset also includes a device for releasably attaching the acoustical receiving cup to a telephone in a position where the mouth of the cup is disposed closely adjacent the telephone speaker for receiving sound emitting from the speaker. The acoustical cup transmits sound to the earpiece assembly via the acoustical receiving tube. The earpiece assembly has a transmitter mechanism for picking up sounds made by a person wearing the headset, and for transmitting such sounds to the transmitter of the telephone.

What is claimed is:
1. A headset for a cellular telephone, said cellular telephone having a speaker and a transmitter, said headset comprising:
- a) an acoustical earpiece assembly adapted for the acoustical transmission of sound to the ear;
- b) a device for mounting the earpiece assembly on the head in a position adjacent an ear of a person wearing the headset;
- c) an acoustical receiving system comprising:
- i) a flexible acoustical receiving tube having an upper end connected to said earpiece assembly, and a lower end;
- ii) an acoustical receiver attached to the lower end of the acoustical receiving tube; and
- iii) a device for releasably attaching the acoustical receiver to said telephone in a position where the receiver is disposed for receiving sound emitting from the speaker of the telephone, said acoustical receiver being adapted for the acoustical transmission of said sound to said earpiece assembly via said acoustical receiving tube; and
- d) electrical transmitter means attached to the earpiece assembly for picking up sounds made by the person wearing the headset, and for transmitting such sounds to the transmitter of the telephone, said electrical transmitter means including a microphone support extending forward from the earpiece assembly at one side of the head of the person wearing the headset to a position generally adjacent the mouth of the person, a microphone at the forward end of the support, and electrical conductor means for connecting the microphone to a microphone mechanism associated with the transmitter of the telephone;
said acoustical receiving system being operable to transmit sound acoustically from the speaker of the telephone to the ear, and said electrical transmitter means being operable to transmit sound electronically from the person wearing the headset to the transmitter of the telephone.
