Tws wireless earphones can be divided into headsets and earbuds. Tws wireless earphones are generally larger and have a certain weight, so they are not convenient, but the sound quality is good, and their expressiveness is very strong; tws wireless earphones are small and easy to carry, mainly easy to carry Traveling to listen to music and make phone calls, the current true tws wireless earphones, earbuds, can be widely connected to Bluetooth devices. The technology of Bluetooth headsets has been very mature, and the sound quality and applications have greatly improved, which can satisfy most of us. scenes to be used.
According to the principle of energy conversion, earphones mainly have three categories: balanced armature and electrostatic earphones.
1. Moving coil earphone refers to a miniature tws wireless earphones.
When the current passes through the voice coil, the voice coil becomes an electromagnet, which will interfere with or attract the permanent magnet to drive the diaphragm to produce sound. 99.5% of earphones are driven by moving coil. The moving coil driver is durable and reliable. At present, most earphone earplugs fall into this category.
2. Moving iron earphones are also called balanced armature.
The voice coil bypasses a precision iron sheet called "balanced armature" located in the center of the permanent magnetic field. This iron sheet drives the diaphragm to sound under the action of magnetic force. The moving iron is inserted into the center point of a miniature diaphragm through a precisely structured connecting rod to generate vibration and sound. Generally, high-end headphones use moving iron tws wireless earphones.
3.The basic principle of tws wireless earphones (also called capacitive) is to place an extremely thin diaphragm in an electrostatic field.
The change of the input signal causes the fluctuation to drive the diaphragm to produce sound, and the diaphragm is in a changing electric field. The diaphragm is extremely thin, accurate to a few microns (currently the diaphragm of STAX's new generation of electrostatic earphones is accurate to 1.35 microns), and the coil drives the diaphragm to sound under the drive of the electric field. Although the sound pressure level is not as large as that of moving coil earphones, the structure is precise, and the material requirements are very high. Most of them are assembled and debugged by hand, so they are expensive and are basically not considered as daily earphones. But the response speed is fast, all kinds of tiny details can be eliminated, and the distortion is extremely low.
The structure of the earphone cavity is mainly open, semi-open, and closed (closed).
1. Open style: Open style tws wireless earphones are currently the more popular style of earphones. Generally speaking, it has a natural sense of hearing and is comfortable to wear. It is commonly used in tws wireless earphones for home appreciation. The feature is that the sound-transmitting ear pads are made of sponge-like microporous foamed plastic. It is small in size and comfortable to wear. It no longer uses thick sound-dyed pads, so there is no sense of isolation from the outside world, and the sound can be leaked, and vice versa, the outside sound can also be heard. If the earphone is open to a high degree, you can hear the sound from the other side unit, forming a certain mutual feed, making the listening feel natural. But the low frequency loss is large, and some people say that its low frequency is accurate.
2. Semi-open type: There are no strict regulations, and the sound can only enter but not exit, or only exit but not enter. Adjust accordingly as needed. It is a new type of earphone that combines the advantages of closed and open tws wireless earphones. It adopts a multi-diaphragm structure, except for an active active oscillator. In addition to the diaphragm, there are multiple passive driven diaphragms. It has many characteristics such as full and rich low-frequency description, bright and natural high-frequency description, and clear levels. This kind of earphone is widely used in many tws wireless earphones.
3. Closed type: The earmuffs put a lot of pressure on the ears to prevent the sound from coming in and out, and the sound is positioned correctly and clearly, which is more common in the professional monitoring field. The closed earphone wraps your ears with its own soft sound pad so that it is completely covered. This type of headset has a large sound pad, so it is larger, but with a sound pad, it can be used in noisy environments without being affected. The earmuffs put a lot of pressure on the ears to prevent the sound from entering and exiting, and the sound is correctly positioned and clear. This is more common in the professional monitoring field. The disadvantage is that the bass is seriously stained.
