A device that converts sound into electrical energy for sending to a separate point.
Device which converts acoustical energy (sound) into electrical energy for transmission to a distant point.
A user end device used to transmit and receive audio-frequency signals generated by voice.
An instrument that directly modulates carrier waves with voice or other acoustic source to be transmitted to a remote location and reconverted into received waves of audible signals. Invented by Alexander Graham Bell.
electronic equipment that converts sound into electrical signals that can be transmitted over distances and then converts received signals back into sounds; "I talked to him on the telephone"
transmitting speech at a distance
a device that enables us to hear sound at a distance, just as television enables us to see at a distance
a device that translates one's speech into analog electrical signals, allowing them to engage in communication over extended distances
a low voltage transmitter and receiver for distributing and reproducing sounds over a distance
an audio class device (for the speech) and a HID class device (for the buttons)
a rather primitive peripheral device
a wonderful tool because it encourages verbal communication
A device that converts acoustical (sound) energy into electrical energy for transmission to a distant point.
A device often taken for granted if you have easy access to the use of one. Used mostly for voice communications. A telephone takes sound and converts it into electrical waves, which can then be sent over communications channels.
A user end instrument that is used to transmit and receive voice-frequency signals.
Apparatus designed to convert sound waves into electrical waves which are sent to and reproduced ata distant point.
The telephone or phone is a telecommunications device which is used to transmit and receive sound (most commonly voice and speech) across distance. Most telephones operate through transmission of electric signals over a complex telephone network which allows almost any phone user to communicate with almost any other.
