Step 6200: and comparing the preset sound intensity reference value information with the current optimized sound information.
The preset voice intensity reference value information may be preset previously, or the acquired currently input singing voice information may be defined as voice intensity reference value information; the currently input singing voice information is used as the voice intensity reference value information, the corresponding reference can be adjusted according to the currently input singing voice information, and large deviation is avoided under the condition that the voice intensity corresponding to the currently optimized voice information is reduced.
Step 6210: and if the current optimized sound information is smaller than the sound intensity reference value information, outputting the current optimized sound information as the current playing information.
Step 6220: and if the current optimized sound information is larger than the sound intensity reference value information, reducing the sound intensity corresponding to the current optimized sound information until the sound intensity is lower than the sound intensity reference value information, and outputting the sound intensity as the current playing information.
If the current optimized sound information is larger than the preset sound intensity reference value information, the current optimized sound information is processed to reduce the sound intensity until the current optimized sound information is smaller than the sound intensity reference value information, which shows that no matter how the current optimized sound information is circularly amplified, the relatively formed amplification gain is smaller than 1, so that the amplification process is always close to 1, and the wireless amplification condition can not be generated, thereby achieving the problem of preventing howling.
The method for reducing the sound intensity corresponding to the current optimized sound information comprises the following steps:
step 6300: and acquiring current optimized sound information.
Wherein, the current optimized sound information is a voltage signal; .
Step 6400: and reducing the voltage signal corresponding to the current optimized sound information through the preset voltage reduction resistor.
The voltage reduction resistor can be a fixed resistor, namely the voltage reduction resistor is used for reducing the sound intensity of the current optimized sound information, and the voltage signal reduction mode is simple in structure and easy to achieve. The voltage reduction resistor can also be provided with a plurality of voltage reduction resistors, and the resistance values of the voltage reduction resistors are sequentially increased; the specific reduction process is shown in step 6500.
Step 6500: and forming a priority according to the resistance value of the voltage reduction resistor from small to large, and sequentially passing the current optimized sound information through the preset voltage reduction resistor according to the priority to reduce the current optimized sound information until the current optimized sound information is lower than the sound intensity reference value information.
Different voltage reduction circuits are switched in according to the priority through the arrangement of a plurality of resistors, so that the voltage signal is reduced through the combination, namely, the reduction degree of the sound intensity is ensured to be small, the subsequent sound output is not influenced, and the output sound can be ensured not to generate howling.
The input singing voice information which is not subjected to reduction processing is used as the output voice information transmitted to the next Karaoke treasure, and in the process of any one-level transmission, the voice intensity corresponding to the input singing voice information transmitted previously cannot be gradually reduced, so that the input singing voice information transmitted at each level can be ensured to keep corresponding intensity, and the normal transmission is ensured to form a chorus mode. Therefore, the input singing voice information acquired by the last K singing treasure is used as the output voice information output by the last K singing treasure to be output.
