1. Field of the Invention
The present invention relates to a multimedia playing/recording device, and more particularly to a multimedia playing/recording device that can play digital multimedia data provided by a computer at regular time. If there in an incoming call from a web phone, the button on the device can be pressed to control and receive the call from the web phone, and a software program is used to control and automatically switch the device into a telephone. Further, the present invention also includes a phone receiving/transmitting interface which can be connected to a phone or a mobile phone for making and receiving calls from the phone voice playing/recording device.
2. Description of the Related Art
A web phone allows users to make a call to any place around the world within a few minutes, and most importantly the cost for such call is very low or even free of charge. Therefore, the web phone becomes very popular after the web phone and its application software such as Skype MSN, or other softphone are introduced. For example, Skype uses a softphone caller having a very good voice quality, and adopts an end-to-end encryption. Furthermore, Skype also allows voice conference of many parties to satisfy the requirements of multinational enterprises.
In general, a set of earphone and microphone is required for using a softphone. The set of earphone and microphone is inserted separately into a microphone socket and a speaker output socket of a computer. Therefore, the web phone can be used with the control of the softphone. However, the foregoing application does not allow its use simultaneously for many parties (such as a conversation between family members and friends at a remote end) since the earphone and microphone set is provided for the use of one person and hanged on the user's body. Furthermore, the user's movement will be limited as well.
Therefore, a phone voice receiving/playing device is needed, such that the device can play digital multimedia data of a computer at regular time. If there is an incoming call from a web phone, a software program controls and automatically switches the phone voice receiving/playing device into a phone for the use of many parties.
It is a primary objective of the present invention to provide a phone voice receiving/playing device that can play digital multimedia data of a computer. If there is an incoming call from a web phone, a software program controls and automatically switches the multimedia playing/recording device into a phone for receiving a softphone call.
Another objective of the present invention is to provide a phone voice receiving/playing device, such that if there is an incoming call from a web phone, a speaker will output a voice signal and a microphone will receive and record a voice signal for using the phone voice receiving/playing device by many parties.
A further objective of the present invention is to provide a phone voice receiving/playing device having a phone receiving/transmitting interface, such that the phone receiving/transmitting interface can be connected to an external phone or a mobile phone for making or receiving a call.
To achieve the foregoing objectives, the phone voice receiving/playing device of the invention comprises: a casing having a front casing and a rear casing, and the front casing is engaged with the rear casing, and the front casing has at least one first opening; a printed circuit board installed in the casing for containing the following elements; an interface connector coupled to the printed circuit board by passing a cable through the casing for coupling a computer system; an interface medium chip set coupled to the interface connector; a medium enhanced chip set coupled to the interface medium chip set; a medium playing device coupled to the medium enhanced chip set and exposed from the first opening; and a voice input device coupled to the medium enhanced chip set; such that if a software program of the computer system detects an incoming call signal of a web phone, the software program will control the interface medium chip set to convert an interface serial signal and a medium signal. After the signal is processed by the medium enhanced chip set, the signal is outputted from the medium playing device. Meanwhile, the signal inputted from the voice input device can be sent to the computer system by a reverse process.
To make it easier for our examiner to understand the objective of the invention, its structure, innovative features, and performance, we use a preferred embodiment together with the attached drawings for the detailed description of the invention.
The present invention will now be described in more detail hereinafter with reference to the accompanying drawings that show various embodiments of the invention.

The interface connector 11 is coupled to the printed circuit board 10 by passing a cable 111 through the casing 30, and preferably comes with a digital serial signal USB or IEEE1394 interface plug for coupling a USB or IEEE1394 port 21 of a computer system 2 (a shown in
The interface medium chip set 12 is coupled to the interface connector 11 and further comprises a digital serial signal USB or IEEE1394 interface for processing an interface serial signal of the interface connector 11. The interface medium chip set 12 can execute the conversion between the interface serial signal and a medium signal, and the medium signal can be sent to the medium enhanced chip set 13 for processing.
The medium enhanced chip set 13 is coupled to the interface medium chip set 12 and capable of executing an echo cancel, a volume control, and a surrounding process for the medium signal outputted from the interface medium chip set 12, and then the medium signal is outputted from the medium playing device 14.
The medium playing device 14 is coupled to the medium enhanced chip set 13 and exposed from the first opening 311, and preferably comes with a speaker, so that several parties can listen to the content of the voice signal of the web phone through the speaker. The phone voice receiving/playing device 1 of the invention further comprises an external speaker socket 18 coupled to the medium enhanced chip set 13 and exposed from the second opening 321. If an external speaker (not shown in the figure) is plugged into the external speaker socket 18, the speaker 14 will be disabled to improve the voice effect of listening to the multimedia signals.
The voice input device 15 is coupled to the medium enhanced chip set 14, and preferably comes with a built-in microphone exposed from the casing 30, so that users can input voice signals. After the voice signal is processed (such as an echo cancel, a volume control, or a surrounding process) by the medium enhanced chip set 13, the voice signal is sent to the interface medium chip set 12 and converted into the interface serial signal, which is outputted to the computer system 2. To provide a better voice receiving effect, the present invention further comprises a microphone socket 16 coupled to the medium enhanced chip set 14 and exposed from the third opening 322. If an external microphone 4 with a better performance (as shown in
In addition, the phone voice receiving/playing device of the invention further comprises a phone receiving/transmitting interface 17 installed on the printed circuit board 10 and coupled to the medium enhanced chip set 13 and exposed from the fourth opening 323 for plugging in a phone to receive/transmit voice signals. The phone receiving/transmitting interface 17 is a microphone socket or a RJ-11 socket for plugging an earphone microphone 51 (as shown in
