the higher the voltage, the higher the current, and the higher the power outputif the voltage is too low and the sound is amplified, it will easily cause sound distortionwhen using it, choose the volume close to the maximum, which may cause distortion and affect the sound qualityif the current is too low and the horn cannot be brought up, the voltage will be pulled down, which will lead to abnormal operation or poor sound qualityhow to choose the power supply?the power supply with the board is very key, the selected power supply ripple must be small, ripple large power supply will lead to power amplifier bottom noise, there is a current soundhow to select speakers?about the speaker type: commonly used speakers are generally 4-8 ohms50w(r and l channel), maxif you only have 12v 1a, you can have 3-4 inch speakersif you only have 9v12v or 1a 2a power supply, you can also use it but with low power1chip: tpa3116d2(with am anti-interference function)power: dc12-24v/5aadapter speaker: 20-100w, 4-8ωoutput power: max100w(subwoofer)quantità: 1 pzil pacchetto include:1 x amplifier boarddomanda e risposta:1specifica:item type: amplifier boardmodel: zk-tb21materiale: componenti elettronicicolore: blackversione bluetooth: 5if you are above 19v 5a, no problem with 8-10 inches, power must be highly valuedit is recommended to use 18v19v24v power supply with current above 5a0 (nessuna schermatura, 10 m)sensibilità di ingresso: 500 mvingresso audio: aux+bluetoothchannel: 2

Introduce:when we diy audio, because the initial sound is not big, we will add a power amplifier module to the audio to amplify the soundwhen connecting, connect the white port of the 5pin cable with the white anti-reverse port on the module, and connect the female port with the pin headers of other devicesfor the purpose of wiring, we also distribute a 5pin line, one end of the line is a white anti-reverse plug interface (matching the white terminal on the module), and the other end is a 5pin dupont line female interfaceat the same time, in order to facilitate fixing the module to other devices, the module comes with a positioning hole with a diameter of 3mmit outputs two-channel stereo, and the power can reach 10w+10wthis module mainly uses the pam8610 chip, and its gain is 32dbhere we will introduce a power amplifier module-keyes brick pam8610 digital power amplifier 2x10w dual-channel stereo power amplifier module1%)low quiescent currentpopnoise suppressioninterface: 254mm pitch 5pin anti-reverse interface4pin green terminal block (spacing is 35mm)positioning hole: 3mm in diameterpackage includes:1 x pam8610 digital power amplifier boardtechnical parameter:wire length: 200mminput voltage: dc 7-15v10w@10%thd 1 channel output into a 8ω load at 13vlow noise: -90dbefficiency: greater than 90% efficiencygain 32dbwith shutdown/mute/fade functionover current, thermal and short-circuit protectionlow thd+n (0

the sound wave force on the object at the node of the standing wave overcomes the effect of gravity and finally achieves the effect of suspensionworking principle: ultrasonic standing wave levitation is through the existence of a certain distance between the ultrasonic transmitting end and the reflecting end (or another transmitting end) (called the harmonic cavity distance), and the transmitting wave and the reflected wave (or another sound wave) are continuously superimposed to form a standing waveit is not supported to control the floating object to move up and downthe device consists of a single chip microcomputer, a driver chip and two ultrasonic probesmainly used for students or diy electronics enthusiasts to learn about ultrasonic standing wave suspensionworking current: 100mamicro usb 5v powerpackage includes:1 x diy kitworking principle:this is a mini ultrasonic levitation device that can suspend foam balls

the capacity is around 110uf and the passage of the subwoofer (ultra low frequency) can be adjusted through the capacitor limit3: a capacitor is added to the ground at the bass output position to make the bass frequency more smooth2: the treble part uses 2 capacitors in parallel and can be adjusted through the switch to adjust the volumethe penetration of high frequency will be better than that of a capacitor, and the sound quality will be relatively delicatethe frequency division point is above 200hzthis frequency divider is installed on the bookshelf box, which reflects the low frequency betterbookshelf boxes are generally placed in not very large places in the room to listen to, the distance is relatively close, and the commonly used volume is not very large5 meters to 2 meters, and the dull music is not gooduse 3~8 inches of bass, suitable for listening to the low frequency at a distance of 01: in addition to an inductor on the bass line, a capacitor is also connected in seriesthe frequency is particularly clean and nice, suitable for small rooms such as bedrooms, offices, and tea rooms(recommended for woofers of 3-8 inch speakers)impedit is suitable for expressing vocals and strings because there is no interference from heavy bassfeature:brand: weahmodel: 204power: 250wcrossover point: 2500hz-3000hz adjustable, there are 4 frequency points adjustable through two switchesintroduce:this is a high-low two-frequency divider designed for bookshelf boxes
