How to configure the speaker unit of the professional speaker

The sound propagation focuses on the treble, and the power must be more than twice that of the bass. The bass, on the other hand, focuses on the general range of the vocal range, which should be able to respond in the 100Hz range. It is recommended that the woofer power is 120W and the tweeter power is 80W.

Generally, the speaker needs 3 units, with 3 speakers, that is, treble, midrange, and one woofer is enough, which is also standard, but there are also two treble and two woofers, depending on personal like, if you use two woofers, pay attention to the matching of the woofer and the power amplifier output, for example, the output is 8 ohms, the horn is also 8 ohms, and a woofer is enough, if the output is 4 ohms, the horn is 8 ohms, and you can use two woofers to splice together (become 4 ohms), my memories I hope you like it.

Generally, the speaker needs to drive the speaker, it depends on the output power of your amplifier. Generally, hobbyists can use two-unit speakers, such as in bedrooms, computer desktop stereos, etc.

The speakers in the two-unit speaker are a woofer and a tweeter. The diameter of the woofer is more than 7 inches, and the diameter of the tweeter is 2 to 3 inches. Then use the two-way divider to drive the two horns, the circuit diagram is as follows:

L in the figure is a hollow inductance coil, on a plastic frame, with enameled wire wound 200 times, c electrolytic capacitor, the capacity is 5 10 microfar.

There is one, there are two, there are three, there are n more, and if you can generally do two well, you are already a great god.

There are several categories of speakers:(The speaker unit is in the speaker,The performance is the same as the speaker)1,Household speakers:

Floor speakers (bass is more prominent), bookshelf speakers (mid and high tones are more prominent), monitors (HIFI sound quality high fidelity).

These megabytes of speakers listen to the best.

2. Professional stage speaker, 15-inch speaker, high power, no subwoofer, good singing.

The KTV speaker also sings well, and the bass is poor.

3. Ceiling speakers, embedded speakers, wall-mounted speakers, and medium and high tones are suitable for listening to human voices. Listening to ** bass is not satisfied.

4. The subwoofer has only a bass below 200 Hz, no middle and high tones, and is used with a bookshelf box, and cannot be used alone.

5. Computer speakers (with, suitable for students, sound quality is average, **cheap.)

Commonly used speakers are these five categories.

There are also special-purpose speakers, which are relatively rare, so I won't introduce them.

Horn unit. The main structure of the speaker unit is composed of choke ring, sound cone, centering piece, magnetic circuit (including magnet, T iron, voice coil), basin frame, etc., and the impact on the life of the speaker is not only that the voice coil is burned by abnormal use, but mainly the choke ring and the sound cone. Choke:

The life sequence of choke ring materials is cloth edge, rubber-plastic composite edge, silicone rubber edge, foam edge ....... It is more easily damaged by the foam edge (such as JBL has an LX series speaker), due to the use of foam edge speaker unit, it will be cracked and almost scrapped in 3-5 years of normal use, I have helped a friend repair N such speakers, without exception, the foam folding ring is damaged. Of course, the material composition and manufacturing process of the foam edge are different, and its life will be different.

The second is to count the silicone rubber edge, the original domestic "Feile" bass like to use this choke, its shortcomings are mainly if the process is improper, for a long time, it is easy to age and produce inert deformation and tortoise, and affect the use. Today's speaker manufacturers still widely use silicone rubber chokes and plastic-plastic chokes for the majority. Accessories for active speakers:

Cabinet, speaker, crossover, power amplifier (including pre-amp signal selection, equalizer). Bluetooth speaker refers to the audio equipment with a built-in Bluetooth chip and a Bluetooth connection instead of a traditional cable connection. Bluetooth speakers apply Bluetooth technology to traditional digital and multi-** speakers, so that users can avoid the stumbling of annoying wires and listen freely in various ways**.

The speaker connects with Bluetooth** devices such as mobile phones, tablets or laptops for convenience and speed. Bluetooth is a low-cost, high-capacity, short-range wireless communication specification. A Bluetooth laptop is a laptop with Bluetooth wireless communication function.

At present, Bluetooth speakers are mainly portable speakers, the shape is generally small and portable, Bluetooth speaker technology is also gradually valued and accepted by consumers by virtue of its convenient characteristics, most of the common Bluetooth speakers on the market are mono speakers (single speaker unit), and some multi-channel speakers with excellent sound quality (two or more than two speaker units) have also emerged. From the point of view of specifications, although the Bluetooth standard has been proposed, the former is mainly reflected in the RF modulation mode of Bluetooth in line with Wi-Fi, and the latter is reflected in the application of automatic power control, that is, low power consumption. From the perspective of chip-level applications, suitable for the version.

Bluetooth digital speakers have built-in batteries, which are truly wireless. The quality of the built-in battery directly determines the time and service life of the Bluetooth digital speaker. Before purchasing, please carefully inquire about the actual ** time and the number of repeated charging attenuation.

It is recommended that consumers choose polymer lithium batteries when choosing Bluetooth Bluetooth speakers, which is not dangerous. Multi-speaker large-scale home Bluetooth speakers are mainly good at sound quality, which is relatively expensive. Based on the high demand for technical support, it is generally designed and produced for large brand merchants.

What this kind of Bluetooth speaker pursues is the breakthrough of the upper limit of sound quality,Therefore, it is aimed at users who have higher requirements for sound quality,It is relatively niche because it is expensive。
