Description

Network and enclosure for speakers {Speaker network and enclosure}

The present invention relates to a network and enclosure for a speaker, and more particularly, to a speaker network and an enclosure for simplifying network mounting and minimizing damage to the enclosure when replacing the speaker network.

In general, an audio speaker is composed of an enclosure, a unit, and a cross-over network.

The enclosure refers to a speaker case made of wood or plastic, that is, the housing of the speaker, the unit refers to a diaphragm mounted in a round shape on the front of the speaker housing, and the network divides the output signal of the amplifier according to the frequency band. An electronic component device that functions to deliver one or more units to one or more units and is usually mounted on the inner wall of the enclosure.

The enclosure serves to prevent the sounds from the units from canceling each other out. The phases of the sound coming from the front and rear of the unit are reversed, so without an enclosure, part of the sound is canceled out, producing a small volume. So assemble the speaker unit into the enclosure.

The unit is a part that makes a sound by moving the diaphragm. Most speakers are equipped with multiple units. Since one unit cannot output all bands of sound, each unit allocates a band and outputs sound.

At this time, the network is responsible for transferring the signal input from the amplifier (Amplifier) to each unit. The network acts as a filter that distinguishes the sound signal for each band.

Here, the reference point for dividing the band for each unit is a cross-over frequency. When dividing the sound band, not all speakers divide by the same standard, but there are some differences between speaker manufacturers. In general, a divided band is, but not necessarily, one unit responsible for the output. Two units may be in charge of the executive, and several units may be in charge of the lows.

When the network divides the signal band from the amplifier into two kinds of low and high frequencies, it is called a two-way method. When the network divides into three types of low, mid and high frequencies, it is called a three-way method.

For example, "3way 4 speaker, Cross-over Frequency: 2KHz / 8KHz" in the speaker's specification means that the sound band is divided into three kinds of high, mid, and low frequencies, and four units are used for this purpose. The reference frequency for dividing mids is 2KHz and the reference frequency for dividing mids and highs is 8KHz.

The good sound the listener feels must be in harmony with the three elements of the unit, enclosure and network. Even if the speaker of the same cost, the three components sound completely different.

On the other hand, because the good sound depends on the subjectivity of the listener, the listener may go through a speaker tuning process according to his / her preference, and it is common to tune a network known to have the greatest effect on sound quality among the three factors.

Hereinafter, a general network tuning process will be described with reference to FIGS. 1 to 3.
