no. 1 approach

[0020] The hands-free communication device of the present disclosure has a function of outputting a communication of a user using the communication terminal from a speaker included in the notification terminal. Hereinafter, the hands-free communication device 1 of the first embodiment will be described. exist figure 1 In , a block diagram schematically showing the configuration of the hands-free communication device 1 of the first embodiment is shown. like figure 1 As shown, the hands-free communication device 1 is composed of a relay module 20 , a first signal line 40 , a second signal line 50 , and a voice signal transmitting unit 32 .

[0021] The relay module 20 relays the communication between the call terminal 10 and the notification terminal 30 . The communication terminal 10 is a terminal capable of communication, and specifically corresponds to a mobile phone or a smartphone. like figure 1 As shown, the call terminal 10 is configured by including a microphone 11 ...

no. 2 approach

[0044] Next, a second embodiment of the hands-free communication device 1 will be described. In the above-mentioned first embodiment, it was explained that the voice signal transmitting unit 32 transmits the voice signal based on the received call signal to the relay module 20 via the second signal line 50. However, in the second embodiment, when the voice signal is transmitted The part 32 is different from the first embodiment in that the voice signal based on the received call signal is transmitted to the relay module 20 via the first signal line 40 . About other structures, it is the same as that of 1st Embodiment mentioned above. Hereinafter, the difference will be mainly explained.

[0045] In this embodiment, the relay module 20 and the notification terminal 30 are also connected by the first signal line 40 as the differential signal line of the Universal Serial Bus and the second signal line 50 as the ID signal line of the Universal Serial Bus. , and send and receive ...

Abstract

Provided is a handsfree phone device that does not impair the phone communication quality and that can be realized at low costs. The device includes a relay module configured to relay communication between a phone terminal and an informing terminal, a first signal line and a second signal line interconnecting the relay module and the informing terminal, a wired relay section included in the relay module and configured to transmit a received call signal transmitted from the phone terminal to the relay module to the informing terminal via the first signal line, a voice signal transmitting section included in the informing terminal and configured to transmit a voice signal based on the received call signal to the relay module via one of the first signal line and the second signal line, and an echo canceling section included in the relay module and configured to reduce an echo generated when the received call signal outputted from the speaker is inputted to a microphone included in the relay module, with use of the voice signal.

Description

technical field [0001] The present disclosure relates to a hands-free communication device that outputs a call made by a user using a communication terminal from a speaker included in a notification terminal. Background technique [0002] In recent years, in the situation where communication terminals such as mobile phones are widely used, for example, when a driver holds a communication terminal to make a call while driving a vehicle or the like, there is a possibility that the driving operation will be hindered, so a hands-free communication device is used together. As such a technique, there is, for example, the technique described in JP2013-168845A. [0003] The vehicle-mounted hands-free device described in JP2013-168845A includes a speaker and a microphone. When a mobile phone (communication terminal) has an incoming call and starts a hands-free call, the received voice received by the mobile phone is transferred to the communication interface of the vehicle-mounted h...
