Abstract

An integrated sound/telephone headset system is provided comprising a music source, a telephone, a headset having a microphone and earphones, and a control system. The control system receives music from the music source, a telephone ring signal from a telephone line, the telephone audio, and ambient sounds received by the microphone. A handset lift device is manually actuated by the user to select between a bypass mode and operational modes. When operating in the bypass mode, the phone is answered with its handset, and the headset is connected to a mixer with audio input from the music source, the ambient sounds, and a ring tone indicating a ring signal on the telephone line. When in the operational modes, a user initiates or answers a call by lowering the microphone, which switches the headset from the mixer to the telephone and connects the telephone to the telephone line. At the end of the conversation, the user reverses these actions by raising the microphone to switch the headphones back to the mixer and disconnecting the phone from the phone line.

Claims

1. An integrated sound/telephone headset system, comprising:

at least one sound-generating device that transmits electrical signals representative of sound;

a telephonic instrument capable of being coupled to a public switched telephone network and that transmits electrical signals representative of sound and that receives microphone electrical signals for transmission on the public switched telephone network;

a headset that converts received electrical signals into sound, said headset including a microphone for transmitting microphone electrical signals that represent sound detected by the microphone;

indicating means for indicating a mode; and

a control system connected to the sound-generating device, the telephonic instrument, the headset, and the indicating means, wherein the control system connects the headset to at least one of the sound-generating device and the telephonic instrument as a function of the indicated mode, said control system including a mixer that mixes the electrical signals from the sound-generating device with the microphone electrical signals, for a given indicated mode.

2. An integrated sound/telephone headset system according to claim 1, wherein the control system connects the telephonic instrument to the headset to enable the transmission of electrical signals to the headset to produce sound and the transmission of microphone electrical signals to the telephonic instrument, when a telephone mode is indicated.

3. An integrated sound/telephone headset system according to claim 2, wherein the control system sets the telephonic instrument on-line to the public switched telephone network, when the telephone mode is indicated.

4. An integrated sound/telephone headset system according to claim 3, wherein the control system includes a handset lifter device that lifts a handset from the telephonic instrument to enable the telephonic instrument to be set on-line.

5. An integrated sound/telephone headset system according to claim 1, wherein the operation of the sound-generating device can be paused, and the control system includes a pause control device that pauses the sound-generating device for a given indicated mode.

6. An integrated sound/telephone headset system according to claim 1, wherein the control system connects the sound-generating device to the headset to enable the transmission of electrical signals to the headset to produce sound, when a sound mode is indicated.

7. An integrated sound/telephone headset system according to claim 1, wherein the indicating means for indicating a mode comprises a position sensor that senses a position of the microphone, the position being indicative of the mode.

8. An integrated sound/telephone headset system according to claim 1, wherein the indicating means for indicating a mode detects a verbal command through the microphone that indicates the mode.

9. An integrated sound/telephone headset system according to claim 1, wherein the means for indicating a mode can detect a ring signal on the public switched telephone network, and will indicate the mode in response to detecting a ring signal.

10. An integrated sound/telephone headset system according to claim 1, wherein the control system can detect a ring signal on the public switched telephone network, and will transmit electrical signals representing the ring signal to the headset to generate a ringing sound in the headset.

11. An integrated sound/telephone headset system according to claim 1, wherein the control system can detect a ring signal on the public switched telephone network, and further mixes electrical signals representing the ring signal.

12. An integrated sound/telephone headset system according to claim 1, wherein said at least one sound-generating device comprises a computer system.

13. An integrated sound/telephone headset system according to claim 1, wherein the sound-generating device generates electrical signals representative of music.

14. A control system for use in an integrated sound/telephone headset system having a sound generating device, a telephonic instrument, and a headset having a microphone, said control system connected to said sound-generating device, said telephonic instrument and said headset, said control unit comprising:

means for connecting said headset to said telephonic instrument when said control system is in a telephonic mode;

means for connecting said headset to said sound-generating device when said control system is in a sound mode, and

a mixer for mixing electrical signals from said sound-generating device with microphone electrical signals generated by said microphone when said control system is in a selected one of said telephonic and sound modes.

15. The control system of claim 14, wherein said control system is in said telephonic mode when said microphone in said headset is in a lowered position.

16. The control system of claim 15, wherein said control system is in said sound mode when said microphone in said headset is in a raised position.
