Abstract: A supplementary hand free transceiver of a fixing network wired telephone installed to a wired telephone for providing to a non-built-in, non-amplified hand free transceiver is disclosed. The present invention has a hand free transceiver formed by a circuit box suitable for various telephones. No extension line is required and no original function is necessary to be changed. The original telephone can be added with a hand free function (no audio amplifying). Therefore, in using the telephone, the user's hands may operate freely. Furthermore, the receiver is not clamped in the neck portion so that the user may operate a telephone conveniently.

Abstract: A click-muting circuit for a headset microphone connected to a telephone, comprising a user operated mute switch, a click eliminator circuit connected across the microphone for gradually creating a short circuit across the microphone in response to closure of the mute switch, and a hard muting circuit connected in series with the microphone for disconnecting the microphone after the short circuit has been established.

Abstract: A headset storage device includes a headset cradle, a switch and a manual override device. The headset cradle has two positions: a first position when the headset cradle is supporting a headset and a second position when the headset cradle is not supporting a headset. The switch couples the audio signal to the alternate audio system when the headset cradle is in the first position and to the headset when the headset cradle is in the second position. The manual override device forces the headset cradle into one of the two positions regardless of whether the headset cradle is supporting a headset.

Abstract: A telephone indicator system includes a telephone having a base and a handset. The telephone includes a cradle disposed on the base configured to receive the handset. The system also includes an indicator disposed on an least two elevated surfaces of the telephone to notify a user of a telephone message. The indicator may be disposed on at least two elevated surfaces of the handset. The system may also include another indicator disposed in the cradle of the telephone to notify the user of another telephone message while the handset is in use.

Abstract: A telephone having a voice activated dialing feature includes a base, a handset and a transmission line coupled therebetween. Also coupled to the transmission line at a location intermediate the base and handset is a voice recognition/voice tone generation (or “VR/VTG”) circuit for detecting an audio signal originating at sound detection/generation (or “SD/G”) circuitry located within the handset and generating, in response thereto, a series of tones for propagation along the transmission line. Telephone circuitry within the base detects the series of tones and establishes a call in response thereto. The VR/VTG circuit is located entirely within a housing having first and second connector plugs.

Abstract: A device for allowing a user to pick up a telephone handset without using his or her hands is disclosed. The device includes a control unit having a control circuit arranged inside a casing. The control circuit is connected between a telephone and a handset of the telephone. A first activation key is provided on the control unit for allowing signal received by the telephone to be passed to the handset so as to allow the user to answer a phone call by hand picking up the handset. The control unit has a signal receiving/transmitting device which is coupled, via electromagnetic waves, to a counterpart receiving/transmitting device arranged in a headset. A second activation key is formed on the headset whereby the user may actuate the second activation key for allowing signals received by the telephone to be passed to the headset.

Abstract: A headset is provided for telecommunications. This headset generally comprises a hearing/speaking set, as it is called, with at least one ear piece and a band which is placed over the neck or head of the person telephoning. Further, the headset is outfitted with a microphone arm comprising a holder having a microphone which is arranged at the front end of the holder, that is, in direct proximity to the mouth of the person telephoning. It is the object of the invention to improve and simplify the previous solutions for professional headsets. The headset for telecommunications comprises a microphone arm with a free end on which a microphone is arranged, and wherein the audio signals received by the microphone are fed to a telecommunications device for further processing, wherein the headset has an illumination arrangement which is activated when telephoning with the headset.

Abstract: A headset docking device is connected to an audio device by a cord. When the headset is placed in a headset dock, a reel activation button is depressed which instantaneously retracts the cord. Examples of audio devices include a cradle, a cellular phone and a computer, all using the headset docking device.

Abstract: A telephone set comprises a main body and a handset. A storage cavity is formed in the main body for receiving the handset which has a slender body to be inserted into an opening of the storage cavity. A resilient actuator is disposed in the storage cavity and mounted to a hook switch on an electronic circuit within the main body. When the handset is received in the storage cavity, the resilient actuator is pressed to push a button that opens the hook switch to disconnect the circuit of the telephone set. When the handset is removed from the storage cavity, the resilient actuator returns to its free position and releases the button that activates the switch to connect the circuit of the telephone.

Abstract: A portable telephone has an external earphone set electrically connected thereto by a jack plug and socket. The earphone set includes a microphone, at least one speaker, and a remote control unit having a display and a control switch. The portable telephone performs a calling operation depending on an operation of the control switch. When a destination phone number is input by means of voice recognition, it is displayed on the display for check. The dialing is started by the voice input. Further, the input phone number can be corrected by means of the control switch and the voice input.

Abstract: A telephone includes a telephone circuit, a connector, and a switch. The connector is capable of being connected to a voice input/output interface in a network for a computer. The switch makes a selection as to whether a hand-set having a microphone and a loudspeaker is to be connected to the connector or to the telephone circuit. In this telephone, a hand-set accessory therefor can also be connected, as a voice input/output device for the personal computer, to the voice input/output interface for the computer network.

Abstract: Disclosed is a hinge unit for a compact headset, which includes a speaker housing and a microphone housing, and which can be worn on the user's ear. The hinge unit comprising: a pair of opposed side hinge arms provided in the speaker housing at one side thereof; a central hinge arm provided in the microphone housing and assembled between the side hinge arms; and a current-carrying means having a pair of first current-carrying hinge members provided in the side hinge arms, and a pair of second current-carrying hinge members provided in the central hinge arm between the first current-carrying hinge members to slidingly surface contact with the first current-carrying hinge members, allowing the speaker housing and the microphone housing to be fully detached, both mechanically and electrically.

Abstract: Conventional telephone sets normally include a microphone housing defining an opening to the exterior which communicates with a cavity in the microphone housing within which is located an internal microphone, and leads connecting the internal microphone with a PCB. An improvement is proposed, namely the provision of an external microphone connected to a plug which is receivable snugly within the opening, thus to substantially block external sound from reaching the internal microphone. Contact devices link the PCB with portions of the plug and thus with the external microphone.
