A microphone holder includes a housing comprising a base portion having a first aperture therein and sidewall portions disposed on the base to provide the housing with a microphone receiving cavity region. A cover, having a second aperture therein, is disposed over the cavity region of the housing and a baffle is disposed a predetermined distance over a first surface of the cover in the region of the second aperture.

A portable telephone or other signaling system features a remote or portable unit responsive to operator voice and control signals to modulate infrared emitting diodes with narrowband, FM low duty cycle pulses which are received by a telephone network unit operative to demodulate the infrared signals, control the telephone network connection and to transmit and receive voice signals from the network. The portable unit utilizes narrowband FM pulse modulation to optimize the use of battery power. The portable unit further includes means for transmitting on-and-off hook indicia and dialing pulses with the same efficient, narrowband FM pulse modulation. The network base unit includes infrared receiving and decoding means in order to identify audio signals and apply them to the telephone network as well as to detect dial pulses and on- and off-hook indicia to process them for connecting and disconnecting the network unit to the telephone network. Audio signals from the telephone network are sent via a loudspeaker in the network unit to the region of the remote unit along with ring signals.

An automatic handset lifter is used with a wireless communication system. The system attaches to a conventional telephone and creates a communication link between the telephone and a portable device such as a wireless headset. The system automatically detects the ringing of the telephone by sensing magnetic fields of the telephone speaker. Upon ring detection, the system creates a communications link with the remote device and deploys a mechanical lifting device to lift the handset. Lifting the handset activates the telephone cradle switch to answer the phone and thereby allows the remote device to communicate over the telephone.

摘要:
The present invention is directed most particularly to wireless communication systems for interconnection with telephone systems, and more particularly to methods and apparatus to suppress unwanted and annoying audio spikes or bursts that infiltrate the wireless system from ultimately reaching the user's earpiece. An embodiment of the invention is directed to a telephone headset amplifier system with a noise blanking or squelching capability, which attenuates the incoming audio signal when the incoming signal exceeds a predetermined threshold.

A telephone headset including a boom microphone, an earphone, and an ear support constructed and arranged to be adjusted and comfortable for a wearer. The headset is configured with an adjustable ear support to fit a variety of ear sizes without affecting the balance of the ear support on the ear of the wearer. The ear support includes a rotational hinge which is biased into a given position by a compression washer. The earphone is removably and adjustably attached to a mounting ring which in turn is smoothly is movably attached to the ear support by a spring biased ball and socket joint. The combination of flexible joints and removability of the earphone provides the degrees of freedom and striction necessary to permit the earphone to be worn comfortably on either ear of the wearer. A strain relief for the electrical connections is attached to the earphone which directs the electrical connections toward the plane of the head, thereby eliminating a torque which otherwise would tend to dislodge the ear support from the ear. The earphone includes a series of openings in its rear surface to maximize its acoustics. The boom microphone includes a spring biased ball and socket joint to movably fix the orientation of the microphone with respect to the wearer to a good comfort level. The boom microphone ball and socket joint is configured with a tab and stop to prohibit 360 degree rotation of the boom to prevent strain on the electrical connections to the microphone.
