Mobile telecommunications terminal with hands-free operation |
摘要 |
The mobile telecommunications terminal (MF) includes a receiver inset (HK) and a microphone (M), which work together with a conversation circuit (SC), whereby a lower volume level is provided by the receiver inset for an operation of the telecommunications terminal at the ear of a subscriber. An operating element (BE) is arranged in such way, that the conversation circuit is switched in a condition of an existing telephone conversation to a high volume level produced by the receiver inset for a hands-free operation. An additional dynamic speaker may be arranged at the back of the telecommunications terminal for producing the high volume level signal.
