loudspeaker?
portable loudspeaker is divided into two ways: wired connection and wireless connection, mostly waist-mounted and back-mounted. In daily life, the application of loudspeakers brings great convenience to people. However, some problems are often encountered during use, which greatly affect the efficiency and mood of work, so it is necessary to choose a good speaker.
power
power determines the size of the speaker sound. The greater the power, the larger the coverage area of the sound, and the more obvious the amplification effect. The choice of power depends on the individual's situation. A classroom with 40-50 people, a power of 5-10W is enough. A large classroom with 100-200 people requires a power of 18-20W. When purchasing, you should check the power in the parameters. For users who require high power, the ten-degree S516 and S92 are recommended, with both power of 25W, which is fully qualified for the large classroom.
sound quality
The quality of sound is affected by the speaker. A good amplifier requires the sound to be fidelity, and the higher the fidelity, the better, so that the sound emitted by the amplifier is clearer and more realistic. The ten-degree product adopts an independent acoustic acoustic electroacoustic system, with original sound output, clear and natural. Taking the ten-degree M500 as an example, the dual-magnetic high-frequency speaker has a realistic and round sound effect.
appearance
A good speaker will cater to consumers' appearance needs while trying to ensure product quality. It usually uses a strong and wear-resistant material in material selection. Ten degrees of products are made of sturdy and wear-resistant ABS material, and they are also very particular about the color selection, including simple and calm classic black, as well as gorgeous and fashionable rose gold , etc. For users who like a beautiful appearance, the two models of Ten Degree S515 and S718 are recommended, which are stylish and beautiful, light and portable.

How did the howling come about and how to avoid it?
When the amplifier is used, when the speaker of the amplifier is close to the microphone, it is easy to produce howling feedback (natural phenomenon). Four reasons for howling: overload, distance, angle, and frequency.
How to effectively avoid howling?
1. Reduce the volume (adjust the combination of volume and reverb), turn the volume to the maximum and easily cause howling and distortion.
2. Change the direction of the microphone and speaker (do not align the microphone's wheat head to the direction of the birth of the speaker)
3. Stay away from the speaker, and you can avoid it (maintaining a distance of about 1 meter will effectively reduce the occurrence of howling)
4. Try not to have other interference such as mobile phones, radios, etc. during the amplifier process.
5. The distance between the microphone should not be too close. It is recommended that the microphone be 1-1.5 cm away from the mouth.

What is the reverberation function? What is its function?
After a sound wave is emitted, the sound waves will reflect when contacting the surface of the obstacle through the air, causing the sound source to produce various echoes from all directions. After these sounds are mixed together, they are what we call reverb. The reverberation function is an important acoustic feature of buildings such as concert halls and theaters. The sound with reverberation will appear thick, real and three-dimensional, while the sound without reverberation will appear thin and powerless. Ten degrees integrates the reverb function into the amplifier. Taking the S516 as an example, the amplification is thick, three-dimensional and round. It is also equipped with a handheld microphone and a remote control. A amplifier is like a small speaker, bringing the sound effect like a KTV.
