Description

Speaker {A SPEAKER}

The present invention relates to a speaker, and more particularly, the sound generated by the baffle is output between the horn and the duct coupled to the speaker unit to help output the sound generated from the speaker unit and at the same time the sound output from the speaker unit. It's about a speaker that's smooth and can reach long distances.

In general, a speaker refers to a device that finally outputs sound, and in a strict sense, a speaker is divided into a speaker unit and a speaker system. The speaker unit refers to a component composed of a magnet, a coil surrounding the coil, and a diaphragm. And, a speaker system is a kind of set that collects several speaker units, arranges them in a ring, and has terminals for connecting to an amplifier. The term speaker refers to this speaker system.

The high, mid, and low frequencies classified by the speaker are classified according to the frequency used. The points of the frequencies classified into the high, mid, and low frequencies are called crossover points. Then, the frequency is divided into high, mid, and low frequencies according to the crossover point, which is processed by a channel divider.

The signal divided into high, mid, and low by the channel divider is amplified by a power amp and then output through the speaker. In this case, the treble, midtone, and bass have different frequency bands. Thus, a high pass filter (HPF), a band pass filter (BPF), and a low pass filter (LPF) are installed to generate high, mid, and low frequencies in one signal source. do. In this way, the signal filtered by each filter is next amplified by a power amplifier for high, mid, and low frequencies, respectively, and then output to a speaker.

In a generally known structure of a speaker, a magnetic circuit portion consisting of a yoke with a magnet built therein and a bobbin wound with a voice coil, a vibration plate having an inner circumference connected to the upper edge of the magnetic circuit portion, and the vibration The damper for adjusting the vibration of the plate and the frame is fixed to one end of the damper, the speaker is configured as an edge for fixing the upper edge of the upper end of the vibration plate.
