Embodiment Construction

[0029] A BT-compatible in-vehicle device having a Bluetooth (registered trademark) communication function (this application also refers to Bluetooth as “BT”) will be described with reference to the drawings. In one embodiment, it is assumed that a BT-compatible mobile phone having a BT communication function is carried in a compartment of a vehicle equipped with the in-vehicle device, both the in-vehicle device and the mobile phone are in a BT communication executable state.

[0030] Such as figure 1 As shown in , a BT communication system 1 includes an in-vehicle device 2 (which corresponds to a short-range wireless communication device) installed in a vehicle and a mobile phone 3 (which corresponds to a communication counterpart device) carried in the compartment of the vehicle. correspond). The vehicle-mounted device 2 includes a control part 4 (corresponding to the control unit and the control device), a BT module 5 (corresponding to the connection unit and the connection...

Abstract

A short-range wireless communication apparatus is disclosed. The short-range wireless communication apparatus comprises: multiple connection devices and a control device. The connection devices are capable of simultaneously connecting multiple communication interfaces to a communication counterparty apparatus to enable sound data transfer. When the control device determines that, in cases where the communication interfaces are communicably connected, there arises a request to start outputting the sound data transferred by one of the communication interfaces, the control device disconnects another one of the communication interfaces while keeping the one of the communication interfaces connected and causes a sound data output device to output the sound data transferred from the communication counterparty apparatus by the one of the communication interfaces.

Description

technical field [0001] The present invention relates to a short-distance wireless communication device capable of simultaneously connecting a plurality of communication interfaces to a communication counterpart device, the device including a plurality of connection devices for realizing voice data transmission from the communication counterpart device through the plurality of communication interfaces . Background technique [0002] A short-distance wireless communication device having a short-distance wireless communication function can connect a short-distance wireless communication line to a communication counterpart device such as a mobile phone. By connecting an audio data transfer protocol specifying audio data transfer to the communication counterpart device, the short-distance wireless communication device receives audio data transmitted from the communication counterpart device based on the audio data transfer protocol, and outputs sound from a speaker.
