Abstract

When connections among a cellular telephone, a car stereo body part and an operation part are made by wireless and the operation part is attached to the car stereo body part, a call using the cellular telephone is enabled at the side of the car stereo body part and when the operation part is detached from the car stereo body part, a call using the cellular telephone is enabled at the side of the operation part. As a result of this, a driver enables a handsfree call by placing a microphone for driver near to the driver of a sun visor etc. and when a fellow passenger wants to call instead of the driver, a call is enabled in the operation part 11 by detaching the operation part from the car stereo body part.

Claims

1. A handsfree call apparatus provided in a vehicle-mounted electronic device in which an operation part can be attached and detached to and from a body part and can communicate between each of the operation part and the body part and a cellular telephone by a wireless communication line, the apparatus comprising:

an attachment and detachment detector for detecting attachment and detachment of the operation part to and from the body part; and

a control section for enabling a handsfree call through the cellular telephone at the side of the body part when the attachment and detachment detector detects that the operation part is attached to the body part and enabling a call through the cellular telephone at the side of the operation part when it detects that the operation part is detached from the body part.

2. A handsfree call apparatus provided in a vehicle-mounted electronic device in which an operation part can be attached and detached to and from a body part and can communicate between each of the operation part and the body part and a cellular telephone by a wireless communication line, the apparatus comprising:

a first voice input section provided at the side of the body part;

a second voice input section provided at the side of the operation part;

a first communication section for sending voice inputted to the first voice input means at the side of the body part to the cellular telephone by the wireless communication line;

a second communication section for sending voice inputted to the second voice input means at the side of the operation part to the cellular telephone by the wireless communication line;

an attachment and detachment detector for detecting attachment and detachment of the operation part to and from the body part;

a first control section for sending only voice inputted by the first voice input section when the attachment and detachment detector detects that the operation part is attached to the body part and outputting a continuation signal while the operation part is attached to the body part; and

a second control section for sending only voice inputted by the second voice input section when the continuation signal is not outputted from the body part.

3. A handsfree call method using a vehicle-mounted electronic device in which an operation part can be detached from a body part and each of the operation part and the body part is provided with a microphone for call and can communicate with a cellular telephone by wireless, the method comprising:

switching a microphone at the side of the body part and a microphone at the side of the operation part according to attachment and detachment of the operation part to and from the body part;

enabling a call using the cellular telephone at the side of the body part while the operation part is attached to the body part; and

enabling a call using the cellular telephone at the side of the operation part while the operation part is detached from the body part.
