Bluetooth speaker

Today ,i will talk about that Db and degree of distortion, they are counterproductive, so we must control well their's relationship, otherwise will poor the speaker timbre and HI-FI. Distortion There is harmonic distortion, intermodulation distortion and transient distortion different. Harmonic distortion is the sound playback was added to the original signal without  harmonic distortion caused by components; intermodulation distortion affects the pitch of the voice ;transient distortion ,because the speaker has a certain inertia, tub body vibrations cannot keep up with electrical signals changes in an instant of shock as a result of the original signal and the differences between the playback sound. It is very important in the speakers and speaker systems, directly affects the timbre of the restored level, this is often expressed as a percentage, the smaller the number represents less distortion. Common multimedia speaker distortion is less than 0.5% is appropriate and distortio...

Today ,we still talk about whats speaker parameters will directly impact the sounds quality.  Yesterday, we have talk about  Power, and what power is better for a Bluetooth speaker.Today we will talk about  and frequency range and frequency response! (1)frequency range: is refers to audio system replay minimum effective playback frequency and highest effective playback frequency range . (2) Frequency response: is refer to the phenomenon that speaker happen sound pressure with frequency changes and occurre to increases or attenuation, and phase with frequency changes , when a constant voltage output audio signal connected with system .this sound pressure and phase relate to frequency changes (changes volume) called frequency response, units DB (Db) Frequency characteristics of sound systems indicate: ordinate of the decibel scale represent power and  a logarithmic scale represent frequency response . High frequency terminal point and low frequency terminal point...

As we all know that the speaker parameters will directly impact the sounds quality! There are few parameters are very important for the speaker quality ,they are power, frequency range and frequency response,Db, degree of distortion,the sensitivity, impedance,signal-to-noise ratio etc. Today i would to elaborate the what's power and what power is good. power,the maximum sound intensity is depend on power ,just like impact of the speakers voice can have .According to international standards, power has two species mark method: (1) rated power (RMS: sine wave are square):  refers to a rated range drive a 8Ω speakers wave forming continued simulation signal, in interval and repeat  times , speakers do not happen to damaged the maximum electric power. (2)moments peak power (PMPO power): refers to speakers in a short time can bear maximum power. The Federal Trade Commission in 1974 requires power calibration standards: two channels to drive an 8Ωspeaker load, harmon...

As a Bluetooth applications, Bluetooth speaker, compared to other wireless speaker has four unique characteristics，and that's why bluetooth speaker is more and more popular,especially the waterproof portable speaker. 1. Highly practical Bluetooth technology specification of integrated global, mobile phones, PDA, wireless headphones, laptop computers, automobiles, medical devices, computer peripherals and other devices, so long as   it   has the Bluetooth adapter, you can easily connect Bluetooth devices, to transmit data or voice communications, widely available, good compatibility.   2. Easy to operate Bluetooth is an instant technology, it does not require fixed infrastructure, and easy to install and set up, connect without cables, very easy to use, simply complete the pairing will be put into use, operate a lower threshold.   3. Transmission speed fast   Compared with other methods such as infrared, Bluetooth transfer protocol has obviou...

Because of the increasingly popular smartphones and tablet computers, tend to be popular, traffic signal, WiFi information transmission communication technologies can effectively protect the user needs. And only one problem is that all mobile phone manufacturers and notebook brand dealers will not solve the problem, this is the phone quality problem, consumers listening to music on mobile phones is unable to meet as a result of its pursuit of music listening pleasure. Traditional acoustic speaker too heavy to carry, making consumers could not hear the music with the bass away from home (Office),so consumers can only choose the headphone. According to the medical assessment, using headphones to listen to music for a long time, not only the ear fatigue, but also close-range high-decibel voice will affect the ears and hearing. Therefore, we urgently need a portable, and bass speaker to replace the headphones listening music. This spawned a relying on the development of Bluetooth wireless...

1.Bluetooth version Bluetooth speaker  inside buid into a Bluetooth chip, which  makes the comparison with traditional audio devices  is more popular  , whether it is a mobile phone, notebook or tablet can connect Bluetooth speaker  very fast. Meanwhile, the Bluetooth version is one of the most important factors influencing quality of Bluetooth speaker, Bluetooth speaker with a 4.0 version currently on the market. In General,the higher version of Bluetooth, the speaker battery life will be longer ,and transmission distance will farther, Bluetooth compatibility would be more.​ 2.Power Under the same conditions, relatively high power Bluetooth speakers sound will better. Of course, this also depends on the maximum power of the speaker, when power exceed it’s own capacity, there will be a speaker "dancing" phenomenon. In order to avoid and reduce similar cases, ...
