DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Reference will be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.

Referring to FIGS. 3 and 4 , the wireless controller for a video game player of the present invention comprises a video game system 10 and a wireless receiver 50 , wherein the video game system 10 is connected to a wireless receiver 50 . The wireless receiver 50 is for receiving a sound transformer 30 . The wireless receiver 50 comprises a first communication interface 55 for connecting with the video game system 10 , and a first control circuit 51 is conjunct with the first communication interface 55 . The first control circuit 51 comprises a first memory chip receiver 52 , a second memory chip receiver 53 , a first wireless receiving/transmitting circuit 54 , an amplifier 56 and a microphone 57 . The first memory chip receiver 52 is connected to a second communication interface 35 of the sound transformer 30 , and the first wireless receiving/transmitting circuit 54 is connected to a second wireless receiving/transmitting circuit 61 of a wireless controller 60 for signal communication.

The sound transformer 30 comprises a second control circuit 31 , a volume control button 32 , a microphone switch 33 , a headset jack 34 and a second communication interface 35 connecting with the second control circuit 31 , wherein the headset jack 34 is connected with the first control circuit 51 of the wireless receiver 50 through a sound transmission wire 43 .

The wireless controller 60 comprises a third control circuit 62 , a second wireless receiving/transmitting circuit 61 , a button 63 , a microphone switch 64 and a volume control button 65 , wherein the second wireless receiving/transmitting circuit 61 , the button 63 , the microphone switch 64 and the volume control button 65 are connected to said third control circuit 62 .

As described above, the wireless receiver 50 is connected to the video game system 10 , and the first memory chip receiver 52 of the wireless receiver 50 is for receiving a sound transformer 30 and the headset jack 34 is connected with the sound first control circuit 51 of the wireless receiver 50 through a sound transmission wire 43 .

The actual functioning of the wireless controller for a video game player of the present invention will now be described as follows. The signals input by the button 63 on the wireless controller 60 is transmitted in a orderly fashion to the third control circuit 62 , the second wireless receiving/transmitting circuit 61 and the first wireless receiving/transmitting circuit 54 , the signal is further transmitted to the first control circuit 51 , and then finally transmitted to the video game system 10 through the first communication interface 55 .

According to another embodiment of the present invention, the wireless controller 60 comprises a microphone switch 64 and a volume control button 65 for turning the microphone 57 on or off and for adjusting the amplifier 56 of the wireless receiver 50 respectively. When the user adjusts the microphone switch 64 or the volume control button 65 , the signal will be transmitted by the third control circuit 62 and the second wireless receiving/transmitting circuit 61 to the first wireless receiving/transmitting circuit 54 of first wireless receiver 50 , then to the first control circuit 51 to finally control the microphone 57 or the amplifier 56 as desired.

The user can also adjust the microphone 57 and the amplifier 56 of the wireless receiver 50 by operating the volume control button 32 and microphone switch 33 that is set on the sound transformer 30 . When the user operates the volume control button 32 and the microphone switch 33 , the signal is transmitted to the headset jack 34 through the second control circuit 31 , then to the first control circuit 51 through the sound transmission wire 43 , to control the amplifier 56 and the microphone 57 respectively.

Furthermore, the first control circuit 51 comprises an auto-gain circuit 511 , an echo canceling circuit 512 , a volume control circuit 513 and a microphone control circuit 514 . The auto-gain circuit 511 is for balancing the over-loud or over low volume, and the echo canceling circuit 512 is for canceling the cross-talk. The volume control circuit 513 is for controlling the volume of the amplifier 56 , and the microphone control circuit 514 is for controlling the microphone 57 to receive sound signal.

While the invention has been described in conjunction with a specific best mode, it is to be understood that many alternatives, modifications, and variations will be apparent to those skilled in the art in light of the foregoing description. Accordingly, it is intended to embrace all such alternatives, modifications, and variations in which fall within the spirit and scope of the included claims. All matters set forth herein or shown in the accompanying drawings are to be interpreted in an illustrative and non-limiting sense.
