Abstract

This invention discloses a sound mixing apparatus comprising a wireless signal receiver, an outside sound receiver, a sound mixing device and a wireless signal emitter. A first wireless signal is received by the wireless signal receiver and transformed into a first sound signal then sending to the sound mixing device. An outside sound is captured by the outside sound receiver and transformed into a second sound signal then sending to the sound mixing device. The first sound signal and the second sound signal are mixed to form a third sound signal by the sound mixing device, and the third sound signal is transmitted to the wireless signal emitter. The third sound signal then transformed to a second wireless signal and emitted by the wireless signal emitter.

Description

201127095 VI. Description of the Invention: [Technical Field] The present invention relates to a sound mixing device, and more particularly to a sound mixing device capable of mixing external sound and FM broadcast music. [Prior Art] At present, it is almost a habit to listen to FM radio. Whether it is at home, walking or driving, it is quite common to listen to the radio to solve boring time. When listening to some music stations, or when the radio plays your favorite songs, I always want to sing along with the humming, but I want to hear the feeling of singing and singing with music, but now there is no corresponding technology or The equipment can be instantly mixed and played, so that singing must spend a lot of money on KTV or equipment fixed in the home, and there is no way to sing at any time. SUMMARY OF THE INVENTION In view of the above-mentioned problems of the prior art, one of the objects of the present invention is to provide a sound mixing device for solving the inconvenience of having to go to an entertainment place when singing with music and not being able to sing anytime and anywhere. In accordance with another aspect of the present invention, a mixing apparatus is provided that includes a wireless signal receiver, an external audio receiver, a mixer, and a wireless signal transmitter. The external audio receiver includes a wired module and a wireless module. The wireless signal receiver receives the first wireless audio 201127095 signal, converts it into a first sound signal and transmits it to the mixer; and the external audio receiver captures the external sound to form a second sound signal and transmits it to the sound mixer. The mixer mixes the first sound signal and the second sound signal to form a third sound signal and transmits the third sound signal to the wireless signal transmitter. After receiving the third sound signal, the wireless signal transmitter takes the second wireless signal Audio signal is sent. The wired module is connected to a wired microphone, and the wireless module is connected to a wireless microphone. • The first wireless audio signal and the second wireless audio signal are frequency modulated (FM) signals. Among them, the wireless module is a Bluetooth module. Among them, the wireless microphone is a Bluetooth microphone. Among them, the mixer is a digital signal processor (DSp). According to the present invention, the sound mixing device of the present invention can have the following advantages: # This mixing device can transmit the sound by wireless transmission by receiving the audio of the wireless FM broadcast and mixing with the external sound. The signal is played to another device that can listen to the FM radio station, thereby saving the cost of singing at the entertainment venue and improving the convenience of singing at any time and any place. [Embodiment] Please refer to Fig. 1, which is a block diagram showing an embodiment of a sound mixing device of the present invention. In the figure, the mixing device 1 includes a wireless signal receiver 10, an 201127095 external audio receiver 11, a mixer (such as a digital signal processor, DSP) 12, and a wireless signal transmitter 13. The external audio receiver u ^ includes a wired module 110 and a wireless module ln. The wireless signal receiver 10 receives the first wireless audio signal 20, converts it into a first sound signal 21 and transmits it to the mixer 12; and the external audio receiver u = passes the wired module 11 or the wireless module ln The cable = u and the wireless microphone 15 are respectively electrically connected to capture the external sound signal ^ and /, an audio signal 23 is transmitted to the mixer 13, and then the first sound signal 21 and the second sound signal 23 are mixed. The = 24 is transmitted to the wireless signal transmitter 13, and after receiving the third audio signal 24, the wireless transmits it to the second wireless audio signal 25. Miscellaneous two-parameters, Fig. 2, which is another embodiment of the sound mixing device of the present invention, the 'mixing device 1 of the present invention can be installed in two: parallel group, and the wireless module is mixed (That is, the Bluetooth mode will receive the audio, driving, and singing of a certain FM (FM) channel; when the channel is empty, the sound can be broadcasted in a mobile phone 5, and the mixing device of the present invention can be built in. Sound, no-match - hands-free microphone 6 mixing device is transparent, crystal & 1, 3 grams of wind 6 to capture the user's voice, the audio module of the audio receiver receives the hands-free listening 201127095

The sound of the microphone microphone 6 is taken, and the workflow of the mixing device is not repeated as described above. The final mixing device can send the FM signal to the mobile phone 5, and then the built-in speaker 0 of the mobile phone 5 plays the mixed sound; or can open any sound 7 that can receive the FM frequency nearby, and set the sound 7 to adjust to The present invention can be used at any time by the channel set by the mixing device. With the sound mixing device of the present invention, we can transmit the wireless FM radio broadcast and mix with the human voice, and then transmit the mixed signal to another device that can listen to the FM station by wireless transmission. This saves the cost of singing at a entertainment venue and enhances the convenience of singing anywhere, anytime. The above is intended to be illustrative only and not limiting. Any changes or modifications that come within the spirit and scope of the invention are intended to be included in the scope of the appended claims.
