Why are large portable speakers more popular?

Nowadays,large portable speaker are very common in the market. Not long ago, Meizu also released a small Bluetooth speaker. So why are large portable speakers so popular?

How to use tws bluetooth headset

After the tws bluetooth headset is paired, the mobile phone needs to search for bluetooth devices. Generally, it takes about 5 seconds tosearch for the tws bluetooth headset.Most cell phone passwords are 0000 or 1234, but some are specially set by the manufacturer, which will be detailed in your tws bluetooth headset manual.

Advantages of live broadcast

How to better choose and use dancing speaker

For music lovers, they have a set of their favorite sound system, and one of the important components-speakers, play a decisive role in the quality of the replay sound, so when choosing dancing speakers, they will take great pains, but apart from comparing the speaker technology In addition to indicators and listening evaluation, some small knowledge about dancing speakers will also allow you to better choose and use dancing speakers.

The advantages of bluetooth wireless headphones

Don't worry, in order to cope with these situations, bluetooth wireless headphones have emerged, of course, the invention of bluetooth wireless headphones must be attributed to the development of science and technology and the infinite wisdom of human beings.

How to select mini portable speaker

We always want a clean voice with no other noise.However, when a mini portable speaker makes sound, it will produce noise, which comes from the resonance of the box body, the reflection inside the box body, the distortion of the mini portable speaker when it makes sound,the reverberation produced by the environment and so on.

Tws bluetooth speaker sound quality evaluation

In recent years the tws bluetooth speaker developed rapidly, all kinds of styles a lot, look to attract fashion. Tws bluetooth speaker size is getting smaller but better sound quality, people are increasingly demanding high quality. How to assess the sound quality is good or bad? Can be judged from the following aspects:


Stereo feeling

The sense of the sense of space (sense of surround), the sense of orientation (sense of direction), the sense of depth (sense of thickness), and the like, are called stereo sounds. Nature of the various sound field itself is full of three-dimensional sense, it is analog sound source sound like a most important feature. The de Boer effect proves that the physiological characteristics of human ear are as follows: when the tws bluetooth speaker pressure difference Δp = 0dB and the time difference Δt = 0ms, the senses of the two sound sources are the same, There are two sound sources; and when △ p> 15dB or △ t> 3ms, the human ear to feel there are two sound sources, sound pressure to the sound pressure or the sound source before the move, the sound of every 5dB The pressure difference is equivalent to the time difference of lms. Haas effect further proves that when △ t = 5ms ~ 35ms, the human ear feel that there are two sound sources; and when the time of near-reflex sound, delayed direct sound or two sound sources △ t> 50ms, even once The loudness of the reflected sound or lagged sound is many times greater than that of the direct sound or the leading sound, and the sound source direction is still determined by the direct sound or the leading sound. According to the physiological characteristics of the human ear, as long as through the sound intensity, delay, reverberation, space effects and other appropriate control and processing, artificial tws bluetooth speaker manufacturing in the ears with a certain time difference △ t, phase difference △ θ, Poor △ P sound state, and make this state and the original sound source in the binaural sound waves produced exactly the same state, people will be able to truly and completely feel the stereo sound reproduction. Compared with monaural sound, Tws bluetooth speaker usually has a decentralized sound distribution of the sound volume properly, high definition, low background noise characteristics.

Positioning sense

If the sound source is around, up and down, before and after the recording of different directions to send, the receiver should be able to reproduce the sound of the original sound field sound source reproduce the orientation, which is positioning. According to the physiological characteristics of the human ear, from the same sound source to reach the ears of the direct sound of the maximum time difference of 0.44ms ~ 0.5ms, while there is a certain sound pressure, phase difference. Physiological and psychological proof: 20Hz ~ 200Hz bass mainly by the two ears of the phase difference positioning, 300Hz ~ 4kHz Alto mainly by sound pressure differential positioning, higher treble mainly by time difference positioning. Visible, the location of the main sense of the direct arrival of the first to reach the ears of the decision, and the delay to reach the ears of a reflection of the sound and the reflection of the reverberations of the main four times the main simulation of the spatial surround sound.

Sense of space

Although a direct reflection of sound and sound, little effect on the direction of sound, but the reflection is always from all directions to reach the ears, the size of the surrounding space to determine the hearing has an important impact, so that the human ear has been surrounded surrounded Of the feeling, this is the sense of space. Sense of space is more important than positioning.

Layering feeling

Sound high, medium and low frequency response balanced, treble homophonic rich, clear and slim and not harsh, midrange bright highlight, plump full but not blunt, bass thick without nasal.

Thickness feeling

Bass steady strong, thick and not muddy, treble is not missing, moderate volume, a certain brightness, reverb appropriate distortion small.

Clear and turbid

Sound system to make people feel clear, the frequency response should be wide and uniform, especially in the high-frequency density, appropriate reverberation, can better distinguish the instrument's tone and location, otherwise called turbidity.

Rounded and hairy

Mellow is not distorted, especially in the high-frequency distortion of a very small voice, this kind of sound feel happy, sweet. Bass is not muddy, tenor is not blunt, treble does not pierce. Hairy and mellow relative, the main feeling is rough voice, there is audible distortion. If the sound of 5% distortion, most people have a feeling of hairy, professionals can listen to 3%.

Plump and withered

Sound thick, loudness, a sense of good high-frequency, reverberation than the foot, good transient response is called fullness, otherwise it was withered.

Bright and gray

Bright refers to the sound field in the high, medium and bass balance on the basis of slightly prominent in the treble, and there are rich homophones, reverberation, moderate distortion. Gray refers to a serious lack of treble, bass relaxation, poor resolution.

Broad and thin

Wide sound frequency response, treble bright, bass sufficient, thin voice often lacks bass or treble.

Dry and wet

Mainly refers to the reverberation effect. Reverberation time is short, the depth of the performance of dry. Reverberation too, the performance of wet. The tws bluetooth speaker of the wet and dry is sometimes determined by the software can also be caused by the listening environment.

Scene feeling

Sound bright, the proliferation of good, there is a certain reverb, especially in the 800 ~ 5000Hz more intensive sound, the closest effect of the concert hall, known as a good sense of the scene.
