| 摘要 |
The present invention relates to a voice recording and playback unit incorporated into a handsfree kit for a portable cellular telephone used in a vehicle which uses a single-chip voice recording/playback device to directly record one-way or two-way conversations occurring between the cellular telephone and either the external microphone or speaker components of the handsfree kit. When the telephone is up on a call, the voice recording and playback unit can record both sides of a conversation. When the telephone is not up on a call, the voice recording and playback unit functions as a memo pad and allows the user to dictate messages or memos. Control of the voice recording and playback unit is accomplished by the use of an actuator, such as a pushbutton mounted on the cradle of the handsfree kit or a sequence of keys on the keypad of the cellular telephone. |
