Hi-fi headphones have a wide frequency response and low distortion are desktop HIFI audio can not be compared, especially

some brand headphones, even some top-quality speakers can not be compared. High fidelity headphones to listen to music, its high resolving power, without overly complex configuration, the cost is not worth the stool can get multiple playback sound levels to its desktop portfolio, while easy to use, the effect is not the time to appreciate the impact of the environment . Fidelity headphones sound field balance, level of detail is clear, dynamic enough, especially for high-frequency reproduction with elegant real sweet and warm sound. In addition to a good selection of headphones, choose a good headphone amplifier is also a great need to focus on work. If silver pocket more, then of course you can buy a thousand dollars of finished headphone amplifier, but conservation is our traditional virtues of the Chinese people, the majority of fans here to recommend a pure DC HI-FI headphone amplifier circuit, its pure sound, detail level of clarity, dynamic sufficient bandwidth is very good, and the cost inexpensive, interested persons may wish to try. Circuit diagram is as follows The design is pure DC type, music channel is not a coupling capacitor, so that the music signal if the vehicle is traveling at highway general, high frequency without any coloration amplified and modified by the direct promotion of headphones. Recommended dual 12 ~ 18V transformer can be on this op-amp circuit amplifies part NE5532 into a higher grade of IC to get better results, generally 5532 servo power supply is sufficient, but with a great waste.
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
