How Mylar speaker works
The permanent magnet generates a magnetic field in the annular air gap of the magnetic circuit through the yoke, and the voice coil connected with the loudspeaker paper basin is inserted into the annular air gap. The permanent magnet is surrounded by the external yoke, which can avoid the interference of the external stray magnetic field. In turn, it can also reduce the influence of the permanent magnet magnetic field on the outside. The loudspeaker can make sound, which actually generates sound waves through the piston movement of the diaphragm. The movement of the piston is formed through the mutual inductance between the voice coil and the driving magnet. When the sound passes through the magnetic field in the form of current, the coil will produce vibration of different frequencies due to the change of current strength, and then drive the paper basin to produce sounds of different frequencies and strengths.

What are the main parameters of the mylar speaker?
The main parameters of loudspeaker include rated impedance, power, frequency characteristics, resonant frequency, sensitivity, distortion, equivalent mass, equivalent compliance, elastic coefficient, equivalent volume of total quality factor, equivalent vibration radius, magnetic induction intensity, magnetic flux, linear range, directivity, etc. 1. Rated impedance The rated impedance of loudspeakers is also called the nominal impedance value, that is, the minimum impedance of loudspeakers after the resonant peak. There are 4 Ω, 6 Ω, 8 Ω, 16 Ω and 32 Ω. The rated impedance is usually about 1.1 times the DC resistance of the speaker voice coil. 2. The power of power loudspeaker is divided into rated power, minimum power, maximum power and instantaneous power, and the unit is W. The rated power, also known as the nominal power, refers to the average input electric power of the loudspeaker that works normally and continuously for a long time without obvious distortion. The minimum power, also known as starting power, refers to the reference electric power value that the loudspeaker can be pushed to work. The maximum power, also known as the maximum carrying power, refers to the maximum input power that the speaker can withstand when working continuously for a long time. Instantaneous power, also known as instantaneous withstand power, refers to the maximum power that the loudspeaker can withstand in a short time (10ms), generally 8~30 times of the rated power. 3. Frequency characteristic The frequency characteristic of a loudspeaker refers to the rule that when the signal voltage of the input loudspeaker is constant, the output sound pressure of the loudspeaker on the reference axis changes with the frequency of the input signal. It is a frequency response curve (referred to as frequency response) that changes with frequency, reflecting the radiation ability of loudspeakers to sound waves of different frequencies. The frequency response curve of the loudspeaker is an irregular continuous curve with many peaks and valleys. The resonant frequency of the loudspeaker is taken as the low frequency unlimited frequency, and the intersection of the high frequency end of the frequency response curve is taken as the high frequency upper limit frequency. Frequency range between low frequency lower limit and high frequency upper limit. This is called the effective frequency range of the speaker. The flatter the frequency response curve of the loudspeaker, the smaller the frequency distortion, and the wider the effective frequency range. Generally, the frequency range of bass speakers is 20HZ~3kHz, that of mid-range speakers is 500HZ~5kHZ, and that of tweeters is 2~20kHz. 4. Resonant frequency Resonant frequency refers to the lowest frequency that can be replayed by the loudspeaker, which is related to the diameter of the loudspeaker. The resonant frequency of the bass speaker generally decreases with the increase of its diameter. The resonant frequency of the 6-inch (in=0.0254m) bass speaker is about 50HZ, the resonant frequency of the 8-inch (in=0.0254m) bass speaker is about 40HZ, the resonant frequency of the 10 inch bass speaker is about 30HZ, and the resonant frequency of the 12 inch bass speaker is about 20HZ. Resonant frequency is an important parameter that determines the low frequency characteristics of loudspeakers. The lower the value, the better the quality and strength of the loudspeakers’ bass playback. 5. Sensitivity sensitivity, also known as output sound pressure level, is mainly used to reflect the electroacoustic conversion efficiency of loudspeakers. High sensitivity loudspeaker, which can be driven with less electric power. The sensitivity of loudspeakers can be expressed in two ways: characteristic sensitivity level and average characteristic sensitivity. The former is the most commonly used and has a small error. 6. Distortion The distortion of loudspeakers is mainly shown by the difference between the playback sound and the original sound. It is divided into harmonic distortion, transient distortion, intermodulation distortion and phase distortion. 7. Equivalent mass The equivalent mass of a loudspeaker, also known as the vibration mass, is the sum of the static mass of the loudspeaker vibration system (referring to the mass of the diaphragm and voice coil itself) and the co vibrating mass (referring to the mass of some air layers that vibrate together on both sides of the diaphragm). The equivalent mass is proportional to the diameter of the loudspeaker and inversely proportional to the resonant frequency of the loudspeaker. 8. Equivalent compliance Equivalent compliance, also known as force compliance or sound compliance, refers to the tightness of the speaker mounting system (refers to the softness of the folding ring and positioning support) or the compliance of the displacement after being stressed. 9. Elastic coefficient The elastic coefficient of the loudspeaker, also known as the equivalent stiffness of the vibration system, is a parameter representing the rigidity of the cone basin folding ring and the positioning support, which is proportional to the resonant frequency of the loudspeaker and inversely proportional to the equivalent mass of the vibration system. 10. Total quality factor The total quality factor of a loudspeaker, also known as the Qts value, is used to reflect the slow energy consumption of its vibration system, that is, the size of the vibration system loss. 11. Equivalent volume Equivalent volume of loudspeaker refers to the equivalent air volume of the compliance of loudspeaker vibration system. The larger the diameter of the loudspeaker, the larger its equivalent volume. 12. Equivalent vibration radius The equivalent vibration radius of a loudspeaker is also called the effective area of the diaphragm, which represents the area conducive to sound radiation, and generally refers to the length from the center of the diaphragm to the middle of the folding ring. 13. Magnetic induction intensity and magnetic flux Magnetic induction intensity, also known as magnetic gap intensity, is used to indicate the quality mark of magnetic field intensity in the air gap of loudspeakers. The magnetic flux is equal to the product of the magnetic induction intensity and the average value of the air gap area. 14. Linear range The linear range of a loudspeaker refers to the maximum linear displacement of the diaphragm. When the loudspeaker works, if the displacement of the diaphragm exceeds the linear range, the playback distortion will increase. 15. Directivity Directivity refers to the characteristic that the sound pressure radiation ability of loudspeakers in different directions changes with frequency, or refers to the ability of loudspeakers to radiate sound waves to all directions of space. The higher the signal frequency of the input speaker, the stronger the directivity.
Introduction to the Main Components of the mylar speaker
1. Sound Diaphragm The sound film is one of the main components of mylar speaker. It has a decisive impact on the performance and sound quality of the earphone speaker. Without a good sound film, it cannot become a good mylar speaker. The spiral distribution of concave grooves on the sound film is called ripples, which alleviate the wind drum surface caused by the split vibration of the high pitch resonance band, making the peak surface of the frequency response relatively flat, and increasing the strength of the sound film
2. Voice coil The voice coil can be said to be the heart of the mylar speaker and one of the main components of the headphone speaker. After conducting electricity, the voice coil moves in a magnetic field, driving the vibration of the voice film. The voice coil uses methanol to stick self-adhesive wires together
3. Magnetic circuit When the voice coil conducts electricity and vibrates, the part of the coil that supplies the magnetic field at a right angle is called the magnetic circuit. Its function is to form magnetic poles and guide the magnetic flux (beam) of the permanent magnet into the charitable gap as a metaphor, which is the wire that introduces current
4. Bracket The bracket is the mother body for installing vibration components, magnetic circuits, and other components Mask: A protective sound film that emits sound radiation, so its size and shape have an impact on the characteristics of earphone speakers.
