General knowledge of helmet and procurement rules
In the strict sense, the helmet is a listening device with the body's large enough to be worn on the head. 4 important things you can not know title = "headset"> This is not the headphone plug suitable for most players. Would you wear a helmet? According to the theory of transduction, the headphones can be divided into two main types: type electrodynamic (moving-coil type) and capacitive (Electrostatic) The principle of electrodynamic type is the electric current passing through the loop current in the magnetic field, to pronounce the diaphragm. The benefits of helmet sale you do not know the characteristics of high sensitivity, can withstand a higher power, stable quality sound and relatively simple structure. hat `s circle capacitive wireless, the diaphragm is generally used as a mobile electrode. When adding the signal to the diaphragm, it gets the sound of the vibration attraction and repulsion due to the change of polarity signal on the posts. It is characterized by broad bands, the sound quality is excellent, but the structural complexity and the price is high.
- What is a good headset then? First, it must have the color of pure tones and athentic
Sampling units of the helmet does not require high power, usually no more than 0.2W. Therefore, the sound can be kept as the economy the original sound source amplification step by step the circuit. Because the application of high-tech materials is currently achieve full range headphones regeneration is not difficult, frequency response a little better indicators helmet is better than the 20-20KHZ, many high-level point up to 10-30KHz, while the distortion of up to 0.2% or less, and that the vast majority of sound systems is difficult to achieve. Because the vibrating membrane of the helmet is lightweight, transient characteristic is good and the controllability is also strong. Unlike speakers who may be affected by the movement of pistons and affect the quality of its big regeneration. Therefore, the headphones have a good resolution, a wide dynamic range and natural sound quality.
- Meaning of birth spacing. Sound travels around your head forward one way round, while the sound system, sound reinforcement before the audience and spread in depth.
So when you wear a helmet sitting in the concert hall at the front of the middle, almost reached the position of the driver, the whole body immersed in music. This feeling can be Extraordinary!
- clear sense of direction. There is only one pivot point, and can accurately restore the provision of the pan is made by the Registrar of the instruments of different audio source, and reappears in full voice played by the band while eliminating different direction.
While it is difficult for the sound system to do so. We know all that after the sound system is placed, there is a fixed listening position. So when you wear the helmet, you can move easily. You must have a good sense now.
When you buy a headset, you must pay special attention to a technical standard, its impedance. Usually, the impedance of headphones is low or average 30-50ohm. Headphones can be plugged directly into a Walkman or other instruments, such as VCDs, LDs, CDs, DVDs, tapes, radio, etc. dynamic impedance of headphones is more upscale than 300 ohms or more, which is available to be encouraged by an amplifier Dedicated headphone, such as: Singh HD-580, HD-600 of the impedance is 300 ohms.
Have you been touched after listening my introduction above, it is better to do, buy a helmet as soon as possible. You can even do not think there will be such a great improvement in sound quality Walkman Once you have changed your helmet.
