摘要:
A telephone terminal includes a receiving detector which detects a signal level of a receiving voice signal incoming from the main device, a transmitting detector which detects a signal level of a transmitting voice signal to transmit it to the main device, an adjustment device to adjust the transmitting voice signal and a controller which obtains a control value capable of switching a communication state from a receiving state to a transmitting state to make an acoustic echo to be added to the transmitting voice signal be minimum, based on each signal level of the receiving voice signal and signal level of the transmitting voice signal, and controls the adjustment device based on the control value.

A tape carrier package is used as a controller for controlling a liquid crystal display panel, and the tape carrier package are connected to each other with use of a heat seal. The liquid crystal display panel is stack to one face of a liquid crystal display panel substrate via spacer, on the other hand, the tape carrier package is stack to the other face thereof, and then, the liquid crystal display panel substrate is attached to a main circuit board by means of a retaining member, thereby the liquid crystal display panel being attached to a display window of a telephone housing. Therefore, a structure around the liquid crystal display panel is simplified, so that the number of components can be reduced, and also an assembling work can be readily performed.

摘要:
A terminal apparatus includes: an network interface that is connected to a communication network for transmitting data packets including a voice packet containing voice data; a microphone that receives voice and converts into a voice signal; a converter that converts the voice signal into the voice packet for transmitting through the communication network via the network interface, and converts the voice packet received by the network interface into the voice signal; a speaker that outputs the voice signal converted by the converter; a storage unit that stores volume values each corresponding to a plurality of different operation modes; a detection unit that detects the operation mode; and a control unit that reads the volume value corresponding to the detected operation mode from the storage unit and controlling a signal level of the voice signal output from the speaker based on the read volume value.
