Abstract

The present invention provides a portable electric guitar that can be used as a general speaker, which allows the sound of a guitar being played on the neck to be amplified through a speaker unit even without a body, and by connecting the speaker unit and the neck with a hinge unit so that the speaker can be folded at one end of the neck, it is easy to carry and allows the guitar to be played anytime and anywhere without being restricted by location. Additionally, the speaker unit can be detached from the neck through a detachable unit, so the speaker can be independently connected to a device capable of listening to music, such as a smartphone, MP3 player, or radio, to play music.

Description

Portable Electric Guitar The present invention relates to a portable electric guitar, and more specifically, to a portable electric guitar in which a speaker that amplifies the sound of the guitar being played on the neck is configured to be foldable at one end of the neck, making it easy to carry and allowing the guitar to be played anytime and anywhere without being restricted by location, and also allowing the speaker to be detached from the neck as needed and used as a means to listen to music. Generally, the guitar is a type of string instrument that produces sound by plucking the strings, and compared to other instruments, it can be applied to various genres of music. In addition, the guitar is relatively easy to play compared to other string instruments such as the cello and violin, and it is an instrument capable of expressing a wide range of pitches and rhythms. It is the most widely known and accessible instrument with various forms, timbres, and functions, and is relatively widely distributed compared to other string instruments. An electric guitar, which is one type of guitar, generally consists of a body in which a sound amplifier is built, a neck coupled to the body, a head coupled to the neck, and strings connected to a bridge mounted on the head and the body. In addition, a pickup that converts the vibration of the strings into an electrical signal is mounted on the front of the body. On the other hand, electric guitars are designed with the body and neck directly connected, and are typically assembled at the time of factory shipment. They are not designed to be disassembled except in special circumstances such as repairs or maintenance. Therefore, since the guitar must be used until it is damaged after being shipped from the factory, there is a disadvantage in that a new guitar must be purchased if one becomes tired of the body shape or other features. Moreover, for a beginner to learn to play the guitar, it is most important to master chords and scales through consistent practice; however, conventional electric guitars, which include both the body and neck, are too bulky to carry around, so there are inevitably many limitations to practicing while on the go without being restricted by location. FIG. 1 is a drawing illustrating the overall configuration of a portable electric guitar according to a preferred embodiment of the present invention. FIG. 2 is a drawing illustrating the state in which the speaker part of the portable electric guitar of FIG. 1 is folded to the neck starting from the hinge unit. FIGS. 3 and FIGS. 4 are drawings illustrating the hinge unit structure of FIG. 2.
