Introduction: Audio horn is the soul of a stereo, which directly determines the quality of the sound quality. It also determines the price of the audio and determines the lifespan of the audio.
A horn is actually a conversion device that converts electrical energy into sound. When different electron energy is transmitted to the coil, the coil generates an energy that interacts with the magnetic field of the magnet. This interaction causes the disk to vibrate because the energy of the electron changes at any time. The coil of the horn will move forward or backward, so the horn's paper tray will follow the movement. This action will change the degree of air density and produce sound.
The first thing you should pay attention to when selecting a speaker is the sound pattern. The most common one is the dynamic sounding. The basic principle is to place a current-carrying wire perpendicular to the magnetic field into the magnet between the north and south poles, and the wire will be affected by magnetic lines and currents. The interaction between the two moves, and a diaphragm is attached to the root line. As the current changes, the diaphragm moves back and forth. At present, more than 90 percent of the cones are dynamically designed. This method is better than the general electromagnetic sound effect, while the use of high efficiency; in addition to the thickness of the diaphragm is also an important factor affecting the sound quality of the speaker, on the other hand the thickness of the speaker also determines the size of the true volume, which are It is a factor that we need to consider.
The choice of partners in the selection of partners is based on the needs of the product to select the most suitable one in order to maximize the benefits, while better ensuring product quality and sales. Shenzhen Xinda Electronics Co., Ltd. is a well-known electro-acoustic enterprise integrating R&D, production and sales. Its products include electro-acoustic products such as loudspeakers, receivers, and microphones. It has rich experience in this area.
Steel poles are commonly used to carry several types of electric power lines, distribution lines and lighting system. Distribution lines carry power from local substations to customers. They generally carry voltages from 4.6 to 33kV for distances up to 30 miles, and include transformers to step the voltage down from the primary voltage to the lower secondary voltage used by the customer. A service drop carries this lower voltage to the customer's premises.
