Portable Guitar Speaker {PORTABLE SPEAKER FOR GUITAR}

The present invention relates to a portable guitar speaker,

More particularly, to a portable guitar speaker which is easy to store and carry by allowing a speaker to be mounted on a guitar body so as to amplify and output the acoustic guitar when it is played using an acoustic guitar.

An acoustic guitar is a guitar that is played with a unique tone by amplifying the vibration of a string through a bass drum, or body, without a separate electrical device, and is often called an augiter.

However, when playing with an acoustic guitar alone in a theater, it is necessary to amplify the sound of the acoustic guitar as it is, and output it through an amplifier, since the sound is small.

As a typical method for outputting a conventional guitar performance, there is a method of mounting a microphone near the sound hole of the body. In this case, it is inconvenient to use the microphone due to the limitation of the installation of the microphone. In order to prevent other sounds It is necessary to use a precise sound microphone. Such a sound microphone is expensive to cost several million won, so it is limited to be used in public.

Accordingly, there is a need for a technology for transmitting the original tones as they are, and a pickup is used as a device for implementing the technology.

Pickups for acoustic guitars are very versatile, depending on the way they are operated,

Typically mounted on other saddle bridges, piezo pickups that convert the vibration of guitar strings into electrical signals to be output, as well as pick-ups used in electric guitars, are mounted on guitar sound holes, A magnetic sound hole pickup that amplifies sound through being transmitted to a head of a guitar body or a vibrating pickup which is attached to a head of a guitar body or neck and converts the vibration transmitted to an electric signal for output.

Among such guitar pickups, there is a "magnetic pickup for acoustic guitar" of Korean Patent Laid-Open Publication No. 10-2000-0057798 (September 25, 2000)

The above-mentioned prior art 1 is a magnetic pick-up apparatus in a guitar string, which has a first pickup for a high tone corresponding to a first guitar string set of guitar strings and a second pickup for bass corresponding to a second guitar string set, Wherein the first and second pickups each have a respective pickup output taken separately from the pick-ups; and a treble adjustment control coupled to the magnetic pickup device for independently adjusting the output from the first pickup And an output adjusting device including the output adjusting device.

However, the prior art is limited to detecting other sounds and converting them into electric signals. In order to amplify and output sound with a human perceivable sound, a separate output device such as an amplifier is required, There is a problem that it is inconvenient for the player to move because the output device and the guitar are connected to each other through a wire.
