Provide an electric guitar amplifier that can perform the action. [Constitution] An input plug B, which is a variable insertion jack, is plugged into the cable connection port of the electric guitar, so that no cable is required by connecting it. Further, it is composed of a battery A and a small speaker C, which are a power supply together with an effector. This is a cableless type ultra-compact electric guitar amplifier with built-in speaker.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention breaks the concept of a guitar amplifier that used to be a conventional cable connection method, and is designed to be directly connected to an electric guitar. Is also built in.

[0002] Therefore, when practicing or performing, it can be enjoyed regardless of location because it saves labor and facilitates carrying.

[0003] Further, an effector for imparting personality to the sound quality is built in, and the sound quality of a standard electric guitar and the sound quality passed through the effector can be arbitrarily selected.

[0004]

[Prior art]

 Conventional guitar amplifiers connect an electric guitar and a guitar amplifier via a cable and exhibit the effect of playing a guitar for the first time.

[0005] In this state, the performance only plays the original sound of the guitar. To obtain a performance effect that requires individuality, an effector that plays a distortion of the sound is connected, and the effect is connected. It needs to be raised.

[0006] Therefore, in a general performance, it is necessary to connect a guitar amplifier, an effector, and an electric guitar by a cable in advance, so that preparation is time-consuming, and is often not used for individual practice.

[0007] Aside from the guitar, it is very difficult to carry a guitar amplifier, an effector, and a cable, and it is often not used even when players gather to perform a simple performance.

[0008] Furthermore, due to the problem of installation location and noise, it is often not used depending on the location.

In addition, if a guitar amplifier, an effector, a cable, and the like are newly prepared, a financial burden on a player becomes large.

[0010] Therefore, although it is indispensable for electric guitar performance, it must be positioned as expensive even in view of the frequency of use.

[0011]

[Problems to be solved by the invention]

 This invention aims to reduce the financial burden by reducing the installation and connection of equipment such as guitar amplifiers and effectors, which are indispensable for playing electric guitars.

[0012] In order to prevent troubles caused by noise, by appropriately controlling the volume, even in a room without soundproofing equipment, such as a home or a friend's house, it is possible to perform without hesitation around. Provide electric guitar amplifiers.

[0013]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in the present invention, a battery for power supply, an effector, and a small speaker are integrated with a super-miniaturized guitar amplifier to commercialize.

[0014] Therefore, there is no need to install instruments such as a guitar amplifier and an effector, and the connection with each instrument is performed by wiring within the instrument or by printed wiring, so that connection by a cable is not required.

Further, since the connection between the guitar amplifier and the electric guitar uses a variable plug-in jack, the connection can be made regardless of the type of the guitar, and the time, place, environment (outdoors, etc.) It is a thing that can be performed without choosing a performance.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a flowchart of the ultra-small electric guitar amplifier with a built-in speaker according to the present invention, and FIG. 2 is a sequence diagram of the ultra-small electric guitar amplifier with a built-in speaker according to the present invention.

In playing the electric guitar, the input plug B, which is a variable plug-in jack formed on the ultra-compact and built-in speaker electric guitar amplifier of the present invention, is inserted into the cable connection port of the electric guitar.

The feature of the ultra-compact electric guitar amplifier with built-in speaker according to the present invention is that connection with a guitar amplifier, an effector, and an electric guitar can be completed by only one operation described above, and no cable is required. It is a cableless type tool.

When the power switch A2 of the connected electric guitar amplifier is turned on, power is supplied from the built-in battery A, and all performance functions are on standby.

In the flowchart of FIG. 1 and the sequence of FIG. 2, the first-stage amplifier G1 is an amplifier serving as a sound source, the voltage limiting amplifier G2 is an amplifier for changing a sound quality, and the low-frequency amplifier G3 is a speaker. This is an amplifier for exhibiting the function of (1).

In the sequence of FIG. 2, IC1 indicates a low frequency amplifier integrated circuit (IC), IC2A and IC2B indicate an operational amplifier (IC), and IC2C indicates IC2A and IC2B. Indicates power input.

When an electric guitar is played in this state, it is converted into an electric signal according to the sound range and sent to the first-stage amplifier G1. To obtain a unique performance such as sound distortion, the sound quality switch E is used. By switching, the standard sound E2 and the distorted sound E3 can be arbitrarily selected.

The music played in this way is played from a small speaker C via a first-stage amplifier G1 through a voltage limiting amplifier G2, and through a low-frequency amplifier G3.

[Effect of the invention]

 The development of the electric guitar amplifier of the present invention does not require installation and connection of equipment such as guitar amplifiers and effectors that are indispensable for playing electric guitars, so that the financial burden is reduced. .

In addition, since an appropriate level of volume is suppressed to prevent troubles caused by noise, an electric guitar amplifier capable of performing a performance act without hesitation in the surroundings even in a room without soundproofing equipment, such as a home or a friend's house. I will provide it.

The connection between the guitar amplifier and the electric guitar of the present invention can be easily made by using a variable insertion jack, so that the connection can be made regardless of the type of guitar.

Further, since a battery as a power source is built in, the performance can be performed regardless of time, place, and environment (such as indoors).
