INSTRUCTIONS: TECHNICAL FIELD OF THE INVENTION The present invention relates to a sound reproducing apparatus, and more particularly to a sound emitting apparatus capable of providing a multi-channel and clean audio. [Prior Art] Music is a good medicine for modern people to relax and wash their minds, and the sound-emitting device for outputting music is one of the necessary tools for modern people. The conventional sound-playing device mainly uses reading devices such as cassettes. The electromagnetic head, the laser head for the optical disc or the processor for reading the audio file, reads the music signal stored in the cassette, the optical disc or the memory and transmits it to the output of the η 八八, the output of the audio is monotonous and has no multi-channel. In addition, users cannot get good audio quality when listening to music in noisy environments. Furthermore, if the user wants to listen to multi-channel and clean audio, it will cost a lot of money on the playback device and the audio-visual equipment. _ Therefore, how to invent a sound emitting device so that the sound emitting device can provide multi-channel and clean audio without spending a lot of money will be actively disclosed by the present invention. SUMMARY OF THE INVENTION In view of the shortcomings of the above-mentioned conventional sound-emitting device, the inventor feels that he has not perfected it, exhausted his mind and researched and overcome it, and developed a kind of sound reproduction based on his accumulated experience in the industry for many years. The device, in order to reach the sound-emitting device, can provide multi-channel and clean audio without the cost of a large amount of money. The main object of the present invention is to provide a sound emitting device which, by means of a virtual sound processing circuit and a noise canceling circuit, causes an output of a multi-channel sound source and a reverse noise source, thereby providing a sound emitting device without requiring a large amount of money. The purpose of multi-channel and clean audio. To achieve the above objective, the sound reproducing apparatus of the present invention comprises: a virtual sound processing circuit that receives a left channel sound source and a right channel sound source to output at least one multi-channel sound source; and a noise canceling circuit by at least a sound source receiver receives at least one noise source, the noise cancellation circuit reversely processes the noise source to output at least one reverse noise source; a central processing circuit controls the virtual sound processing circuit and the noise cancellation circuit to And transmitting the multi-channel sound source and the reverse noise source to at least one sound source output device; and a power supply circuit for supplying power to the central processing circuit, the virtual sound processing circuit and the noise cancellation circuit. The sound source receiver is a microphone, and the sound source outputter is a speaker. Thereby, the sound reproducing apparatus of the present invention can provide multi-channel and clean audio without a large amount of money. DETAILED DESCRIPTION OF THE INVENTION In order to fully understand the objects, features and effects of the present invention, the present invention will be described in detail by the following specific embodiments and the accompanying drawings. A schematic diagram of a preferred embodiment of the present invention, as shown, the sound reproducing device 9 of the present invention comprises a virtual sound processing circuit 2, a noise 200941452 sound removing circuit 3, a central processing circuit 1 and a power supply circuit 4. . The virtual sound processing circuit 2 receives a left channel sound source 2 and a right channel source 2 2. to output at least one multi-channel sound source 2 3 (such as 5.1 channel) 'the noise canceling circuit 3 At least - the sound source receiving H 3 1 (such as a microphone) receives at least one noise source 3 1 1 , the noise canceling circuit 3 reversely processes the sound source 3 i 2 to output at least one reverse noise source 3 2 , the central processing circuit 1 Controlling the operation of the virtual sound processing circuit 2 and the noise canceling circuit 3 to transmit the multi-channel sound source 23 and the reverse noise source 32 to at least the sound source output device 5 (such as (4)), the power supply circuit 4 is powered The central processing circuit 1, the virtual sound processing circuit 2, and the dividing circuit 3. The second figure is a schematic diagram of the application of the preferred embodiment of the present invention. Please refer to the figure of the figure as shown in the figure of the same figure. The sound reproducing device 9 of the present invention can be built in the headphone 6 1 , the speaker 6 2 or the reading. In the taking device 6, when the sound reproducing device 9 of the present invention is used, the reading device 6 transmits the left channel sound source 2 and the right channel sound source Q 2 to the virtual sound processing of the sounding center 9 of the present invention. The circuit 2 causes the virtual sound processing circuit 2 to output the two multi-channel sound sources 23 to the sound source output n5 in the two earphones 6 1 (such as the taste (4) output or the sound source output device 5 in the two speakers 6 2 (such as La P8). At the same time, the noise canceling circuit 3 receives the noise source 3 1 1 by the two-source receiver 3 (for example, a microphone), and the noise canceling circuit 3 reversely processes the noise source 3 1 1 to output the second counter. Output from the noise source 3 2 to the audio source output 5 (such as La P8) in the headphone 6 ,, or the audio source output 5 (such as 八八) in the second speaker 6 2 . When all the audio sources are transmitted to the earphone 6 When the 200941452 power output device 5 (such as (4)) or the sound source output device 5 (such as (4)) in the speaker 62 The reverse noise source 3 2 will cancel the noise source m, and the user can use the sound and clean audio. The user of the present invention does not need to spend a lot of money on the expensive playback device. : Listening to multi-channel audio, in addition, 'users don't have to spend a lot of money on expensive audio-visual decoration to hear clean audio. As mentioned above, the invention is fully in line with the three requirements of patent: new reliance W And the industry is profitable. In terms of novelty and progress, the system uses the virtual sound processing circuit and the noise cancellation circuit to cause the whole source and the reverse noise _ output, and then the audio device can not be = money Provide multi-channel and clean sound (4) utility; in terms of usability, using the products derived from the present invention, the demand of the former market can be satisfied. The preferred embodiment discloses that the skilled person should understand that the embodiment is only used to reduce the scope of the present invention. It should be noted that both the change and the replacement of the change should be set.
