[0003] In the traditional karaoke solution, the customization of smart terminals is troublesome and requires in-depth customization. It is time-consuming to add sound effects to human voices, and it is easy to increase the delay time. At the same time, only smart terminals can produce sound. It sounds unintuitive, making the user's sense of presence weak and easy to lose rhythm
At the same time, the karaoke device cannot be used without the smart terminal

Embodiment 1
[0061] An embodiment of the present invention, such as figure 1 As shown, the present invention provides a microphone, comprising:
[0062] A microphone 100 , an audio transceiver module 200 , a DSP audio processing chip 300 , and a speaker 400 .
[0063] The microphone 100 is used for collecting the first audio signal.
[0064] The audio transceiver module 200 is connected with the smart terminal and the DSP audio processing chip 300 for receiving the accompaniment audio signal sent by the smart terminal, and sending the accompaniment audio signal to the DSP audio processing chip 300 .
[0065] The DSP audio processing chip 300 is connected with the microphone 100, the audio transceiver module 200, and the speaker 400, and is used to receive and mix the first audio signal and the accompaniment audio signal to obtain the second audio signal. audio signal, and send the second audio signal to the audio transceiver module 200 and the speaker 400 .
[0066] The speaker 400 is c...
Embodiment 2
[0080] Based on the foregoing embodiments, in this embodiment, the same parts as those of the foregoing embodiments will not be described one by one. This embodiment provides a microphone, and the DSP audio processing chip in the microphone includes:
[0081] An audio processing module, configured to perform audio processing on the first audio signal and the accompaniment audio signal respectively.
[0082] Exemplarily, the first audio signal is obtained through the microphone, and the first audio signal is input into the audio processing module, and the first audio signal is separately processed by the audio processing module. The accompaniment audio signal acquired through the wireless module is input to the audio processing module, and the accompaniment audio signal is processed separately.
[0083] An audio mixing module, connected to the audio processing module, configured to mix the audio-processed first audio signal and the accompaniment audio signal to obtain the secon...
Embodiment 3
[0106] Based on the above-mentioned embodiment, the parts that are the same as those in the above-mentioned embodiment in this embodiment will not be described one by one. This embodiment provides a microphone, preferably further comprising:
[0107] The delay setting button is connected with the DSP audio processing chip, and is used for receiving a delay level setting instruction, so that the DSP audio processing chip controls the speaker to delay playing the second audio signal.
[0108] Exemplarily, the first audio signal and the accompaniment audio signal are processed by the microphone to obtain the second audio signal, which has improved playback efficiency and simplified the circuit structure of the smart terminal. Even if there may be a delay in the playback of the two, it is a very small delay, and people may not be able to judge it, which is equivalent to the synchronization of the two sounds. But in order to achieve a better synchronous sounding effect, the present i...

Abstract
The invention relates to the technical field of audio frequency, and provides a microphone and an intelligent karaoke system and method. The microphone comprises a microphone head, an audio receiving and transmitting module, a DSP audio processingchip and a loudspeaker; the microphone head is used for collecting a first audio signal; the audio receiving and transmitting module is connected with the intelligent terminal and the DSP audio processingchip, and is used for receiving an accompaniment audio signal sent by the intelligent terminal and sending the accompaniment audio signal to the DSP audio processingchip; the DSP audio processing chip is connected with the microphone head, the audio receiving and transmitting module and the loudspeaker, and is used for receiving and mixing the first audio signal and the accompaniment audio signal to obtain a second audio signal and sending the second audio signal to the audio receiving and transmitting module and the loudspeaker; the loudspeaker is connected with the DSP audio processing chip and is used for receiving and playing the second audio signal; and the audio receiving and transmitting module is also used for receiving the second audio signal and sending the second audio signal to the intelligent terminal, so that the intelligent terminal plays the second audio signal. According to the method for simultaneously sending the voice and the music by the microphone and the intelligent terminal, the customization of the intelligent terminal is simplified.
Description
technical field [0001] The invention relates to the field of audio technology, in particular to a microphone, an intelligent karaoke system and a method. Background technique [0002] With the gradual improvement of people's quality of life in today's society, people's entertainment methods have become diversified. Karaoke products are commonly used devices in many families and entertainment venues, but the karaoke products currently on the market still have the following disadvantages: [0003] In the traditional karaoke solution, the customization of smart terminals is troublesome and requires in-depth customization. It is time-consuming to add sound effects to human voices, and it is easy to increase the delay time. At the same time, only smart terminals can produce sound. It sounds unintuitive, which makes the user's sense of presence weak and easy to lose rhythm. At the same time, the karaoke device cannot be used without the smart terminal.
