Description

Slim speaker with bass frequency variable technology {Slim speaker with bass frequency variable technology}

The present invention relates to a slim speaker to which a variable bass frequency technology is applied, and more particularly to a slim speaker to which a bass frequency variable technology is applied to vary a bass frequency through a baffle portion formed in a moving path of a bass sound.

In general, a speaker is a sound device that emits sound waves by converting an electrical signal into vibration of a diaphragm to generate a small density wave in the air.

Specifically, the loudness of the speaker is determined according to the frequency of the input electrical signal, and the loudness is determined according to the amplitude.

Among them, the height of the sound is expressed by dividing 20 ~ 499㎐ by bass, 500 ~ 1,999㎐ by mid, and 2,000 ~ 20,000㎐ by treble in the range of 20 ~ 20,000㎐.

According to this, the speakers are divided into high, mid and low, and full band, and the high is the tweeter with short output wavelength, and the mid is the midranger or squaker. ), And the low-end drink is a woofer, which means that the output wavelength is long.

In this case, one speaker may be configured to output sounds of various heights from low to high, but there is a disadvantage in that the output sound is not harmonious compared to the input electric signal.

Accordingly, a speaker designed to output sounds of various heights from low to high trebles has a speaker unit for outputting a high tone, a speaker unit for outputting a midrange, and a speaker unit for outputting a low tone. In the case of a speaker unit for output, the diameter of the speaker unit itself is larger than that of the speaker unit for high-power output, and the space of the ring for amplifying the bass becomes larger.

However, in recent years, there has been an increasing demand for slim speakers that are attached to a thin and narrow bottom so that they can output high quality sound signals without compromising the aesthetics of the surrounding environment. It is required to design and develop a slim speaker while outputting the same.

In particular, high-power design specifications are required for speakers installed in large public facilities such as gymnasiums, auditoriums, audio-visual rooms, etc., and the thickness is reduced due to the adoption of a large volume enclosure and a large speaker unit. There is a problem that cannot be designed.

In addition, the speaker installed in a large public space, such as a gymnasium, auditorium, audio-visual room, etc., due to the above-described technical limitations, the speaker is installed in a protruding form without reducing its thickness, thereby not being aesthetically harmonized with the surrounding environment. In order to protect the speaker from an external impact (for example, a ball, a sports facility, and a user impact when installed in a gymnasium), a separate protection net must be provided to further damage surrounding aesthetics.

In addition, in the case of speakers installed in large public facilities such as gymnasiums, auditoriums, and audio-visual rooms, there is a problem that a human accident such as a fall of the speaker due to an earthquake or the like and a collision between the protruding speaker and the user may occur.

The present invention can provide a slim speaker to which the bass frequency variable technology is applied, which can reinforce bass by varying bass frequencies of bass sounds.

In addition, the present invention can provide a slim speaker to which the bass frequency variable technology is applied, which can be installed to face the midrange output unit so that the midrange sounds overlap.

In addition, the present invention can provide a slim speaker to which the bass frequency variable technology with reduced thickness is applied while varying the bass frequency of the bass sound to output a combination of high, middle and bass sounds.

In addition, the present invention by fixing the housing portion to the wall through the fixing bracket portion, the low-frequency bass can be prevented from falling even if the building shakes the accident that the slim speaker to which the low frequency variable technology is applied from the wall due to earthquakes and external forces, etc. It is possible to provide slim speakers with frequency varying technology.
