How do you represent the parameters of the speaker? What is the difference between Speaker 6 and 8?

The speaker is also known as the "horn", the parameters of the speaker:

1. The nominal impedance is the rated impedance, and the nominal impedance is generally printed on the speaker before leaving the factory. Unit: Ohm.

2. Rated power.

It is the power of the speaker to work normally, and it can work if it exceeds the rated power, but it will be distorted and easy to heat.

It can even lead to damage to the speaker. The unit is watts.

w)。3. The wider the frequency response range, the wider the range can emit a variety of sounds, but the relationship between design and process is generally tens of hertz.

to tens of kHz. Unit: Hz.

Horn 6 8 The difference is:

The internal resistance of the horn in Europe is 6; The internal resistance of the horn of 8 ohms is 8.

Because the internal resistance is small, the voltage change will be more obvious than that of 8 ohms, so the sensitivity of its sound quality is higher than that of 8 ohms.

Horn 6 8 The difference is:

The internal resistance of the horn in Europe is 6; The internal resistance of the horn of 8 ohms is 8.

Ou speaker, e68a8462616964757a686964616f31333431363031 Because the internal resistance is small, the voltage change will be more obvious than 8 ohms, so the sensitivity of its sound quality is higher than that of 8 ohms.

1 inch = .

The horn is counted by inches, and 6 inches are inches and inches.

The inch (吋) is a unit of length used in the United Kingdom (UK, i.e. the United Kingdom (Commonwealth) and its former colonies, generally 1in=, in the imperial system, 12 inches is 1 foot, and 36 inches is 1 yard.

In liquid crystal displays, the specifications are generally 17 inches, 19 inches, 22 inches, etc. In mobile phones, the screen size now generally has inch, inch, inch, inch, inch, etc.

In tablets, the screen size is generally inches, inches, inches. The size of the display is usually measured in the length of the diagonal line, measured in inches. Inches are generally abbreviated as "inches" here.

1. Measure the size of the speaker (speaker excitation, bridge lead loss jargon "unit") according to the effective vibration radius. That is, according to the outer edge of the paper cone is not pressed into the diameter of the fixed rubber ring, it is customary to use inches for the caliber of the horn.

2. Most of the rulers used by ordinary people are metric, and after measuring the diameter of the paper cone, there are more sensitive and less centimeters, divided by centimeters is equal to one inch), which is inches.

The relationship between speaker size and power is that the size is large and the power is high. Naturally, the larger the speaker size, the better, and the larger the diameter speaker, the better the performance in the low frequency section, with lower transient distortion and better sound quality.

The size of the speaker is the size of the speaker horn, for a round speaker speaker, it is expressed in terms of its diameter, such as 16 cm; In the case of non-round speaker horns, it is expressed in terms of the maximum dimensions of its appearance, e.g. 15 23 cm. This parameter is mainly for coaxial speakers.

The size of the speaker is large, and the relative power is also large, and it is not beneficial to increase the power of a certain size.

In terms of material, the size of the speaker is large, the area of the vibrating body is large, the air resistance of the vibrating body is large, and the power of the vibrating body should be increased. At present, large speakers are used for low frequencies, and all those who know the horns believe that the horns cannot be in the full frequency band, and the bass does not produce high tones, and the high tones do not produce low sounds. Now there is a magnetic field countermeasure servo horn, which is the full band, high sound pressure, high efficiency, long stroke (100mm), high power (500kw and large), it is already the most ideal horn.

There is no necessary relationship between the size and power of the speaker, and the problem of false standard of the speaker's power has existed for many years.

If there is no false standard, it is the actual power of the power amplifier, and the actual power is slightly less than the power amplifier.

The caliber of the horn of the same power is different, his frequency response performance is different, and the timbre is also different.

If the power is the same, the parameters are the same, the caliber is large, and it must be soft to look at the power, and the power amplifier does not recommend how much caliber the speaker is.

Hello:——1. Any product has the problem of false standard, so "false standard of speaker power" is not discussed. In the power amplifier output, it is all based on power, "it is recommended to push the speaker of what caliber instead of how many watts of horn", which is a non-professional layman's term and is absolutely not credible.

2. "What is the essential difference between the two horns in addition to the caliber?" What is it? ”.

The main indicators of the speaker are: impedance (in ohms) and power (in watts). Because the diaphragm (paper cone) material of the same power speaker is different, the power it receives is also different.

Therefore, there is a difference in the diameter of the same power horn.

3. "Is there a difference in the requirements for power amplifiers?" ”.On the contrary, the horn is the load for the power amplifier configuration, and it should be said how much power the power of the power amplifier is needed.

4. "Why do some amplifiers recommend how big caliber to push instead of how many watts of horns?" ”.This is misleading for the layman.

The speaker must be based on impedance and power, and the voice coil line of the loudspeaker with large power is thicker and can pass a larger current to ensure the sound of the rated power.
