Even though we buy and sell Bluetooth speaker everyday everywhere, but do you know what is a wireless Bluetooth speaker , how to define them? Wireless Bluetooth speaker relies on Bluetooth transfer protocol (A2SP stereo Protocol) messaging wireless speaker, refers to the application of the Bluetooth technology on the traditional digital and multimedia speaker, allow users more freedom to enjoy music. When it comes to "Bluetooth" technology, it is necessary to look at "Bluetooth" is. "Bluetooth" is a support device for short distance communication (10 m) radio technology. It uses microwave frequencies, 1 M bytes per second transfer rate, the maximum transmission distance of 10 meters, by increasing the transmitter power of up to 100 metre, including mobile phones, PDA, wireless headphones, laptop, related peripherals and other devices to wirelessly exchange information. "Bluetooth" technology, to simplify communications between mobile communicati...

Have you been a trouble How to distinguish the waterproof level of Bluetooth speakers？ Today i will tell you how to distinguish the waterpoof level , so that you will know which waeterpoof level you should buy ,if you want to put the speaker into the water. Bluetooth speaker waterproof  protection level 0 meaning no protection 1 drip I type vertical falling water droplets without harmful effects 2 drip II type and vertical direction 15 "within the scope of falling water droplets without harmful effects 3 rainproof type vertical direction and no harmful effects of the rainfall; 4 splash type under arbitrary direction of the water splash no harmful effect 5 antispray type in any direction by the water jet directly without harmful effects: 6 waterproof type arbitrary direction directly by a jet of water can not enter the internal 7 anti immersion type under specified conditions even dip into the water will not impact 8 water medium long time immersion water under Can be s...

Today we will talk about sounds tone and Timbre. Tone means that has a specific and usually steady pitches signal , in common it’s high and low tone level of speaking voice is high and low tone level. It mainly depends on the frequency, but also with the sound intensity. High frequency sounds make the human ear's response was to high pitch and low frequency sounds make the human ear's response to low pitch . Tone frequency (Hz) has a logarithmic relationship changes. Frequency of different instruments playing the same notes, sound different, but their tone is the same, which is he same played the sound frequency . Timbre means sound quality of the voice is a characteristic quality of the voice sound different from another. Different instruments in the same tone, sounds can be different. This is because their base frequency is the same, but the large difference in the harmonic components. Timbre depends on not only the fundamental frequency, but also related to the harmonics o...

Have you think about that use a real gun to play a game on your home after work off, it's really very cool and relax!The AR Gun is a new way to play game which is different from the traditional way. Combined AR technology with electronic technology, cooperate with the AR Gun APP, then you can enjoy augmented reality game experience. Augmented Reality Game Experience Simply need a smartphone and download the AR Gun App (it is compatible with iOS and Android OS), then you can enjoy experience the augmented reality game experience., which is different from the traditional games play. Built-in Virtual Radar With the build-in Virtual Radar, players by walking or turning around to find the enemy, and pull the trigger and kill target object. It seems like that you are the part of the game. How to use  Step1: Open the battery cover and install 2 * AAA battery Step2: Close the battery cover Step3: Search AR-Gun app and download from App store or Goo...

Today we will talk about Signal to noise ratio(SNR),it will directly may you feel the speaker sounds if it's clear or cloundy. SNR Means ratio of normal playback sound signal with noise signal (power). Expressed in Db. For example, a tape recording SNR is 50dB, noise power output signal power higher 50dB. Signal to noise ratio more higher higher, noise more less . According to International Electrotechnical Commission requirements pre-amplifier SNR is higher than or equal to 63dB, post-amplifier SNR higher than or equal to 86dB ,integrated amplifier SNR higher than 63dB . Integrated amplifier SNR the best value should be higher than 90dB ; Radiohead: 50dB of FM stereo, in fact, should more than 70dB;56dB of tape recording (normal),signal-to-noise ratio has improved a lot after the Dolby noise reduction After the Dolby B noise reduction, signal to noise ratio can reach 65dB, Dolby c noise reduction SNR up to 72dB  (all common); CD SNR more than 90dB , high-end can be up to more th...

Today ,we will talk about the Impedance,although this indicator performance do not impact the speaker sounds, it is better not to buy low-impedance, speakers recommended value is the standard of 8Ω. It refers to the speaker input signal ratio of voltage and current. Input impedance of the speaker is generally divided into high impedance and low impedance.Higher than 16Ωis the high impedance of;lower than 8Ωis low impedance.Standard impedance is 8Ωin the of speaker power amplifier same with output power ,and low impedance speakers can get bigger power output, but impedance is too low will cause under-damped and the deterioration of the bass and so on. So although this indicator performance do not impact the speaker sounds, it is better not to buy low-impedance, speakers recommended value is the standard of 8Ω. Headphone impedance is high impedance--32Ω is common. The impedance of the power amplifier and can be marked for equivalent impedance, such as 4Ω output of 130W, rough...
