Abstract

The utility model relates to a multifunctional integrated electroacoustic guitar, which belongs to the field of musical instruments. The multifunctional integrated electroacoustic guitar comprises a sound pickup, a timbre switching circuit and an acoustic frequency decoder, and is characterized in that a synthesis effect processor chip is fixed at the side edge of the electroacoustic guitar, and the synthesis effect processor chip is electrically connected with the sound pickup, the timbre switching circuit and the acoustic frequency decoder respectively. The string sound wave of the sound pickup is converted into electric energy and conveyed to the chip for timbre synthesis, the timbre switching circuit carries out timbre switching via the chip, and the chip carries out effect processing to an acoustic frequency signal, which is processed by an acoustic frequency decoding chip, connected with an acoustic frequency output, and played via a player, thus no external effect processor is needed for timbre switching. The multifunctional integrated electroacoustic guitar is different from a common traditional electroacoustic guitar, belongs to a sophisticated electronic musical instrument integrating multiple functions, is pretty suitable for being used in band rehearsals and live performances, and can achieve a perfect playing effect when being played.

Description

Multifunctional integrated formula electroacoustic guitar

Technical field

The utility model relates to a kind of musical instrument, and particularly multifunctional integrated formula electroacoustic guitar is so that the guitar fan uses widely.

Background technology

Various circuit that connects of electroacoustic guitar musical performance form in the past is also very loaded down with trivial details.If the external effect device of playing at the scene or also need adding in addition during rehearsal changes the required tone color of guitar fan; And effect device is through the power lead power supply; As play time outage at the scene and can't normally play; Effect device must tramp with one's feet when switching tone color and step on, and is very inconvenient.

Summary of the invention

Defective to above-mentioned field; The present invention provides a kind of multifunctional integrated formula electroacoustic guitar, does not need external effect device, when switching tone color, also switches without pin; Use when being highly suitable for band's rehearsal and on-the-spot performance, when playing, can reach perfect playing effect.

Multifunctional integrated formula electroacoustic guitar comprises acoustic pickup, the tone color commutation circuit; And audio decoder, it is characterized in that: the side at the electroacoustic guitar is fixed with a synthesis effect processor chip, said synthesis effect processor chip respectively with acoustic pickup; Tone color commutation circuit and audio decoder are electrically connected.

Said synthesis effect processor chip is provided with external power supply, and function operating key and power switch form closed circuit with the synthesis effect processor chip.

Also be in series with LED display in the said closed circuit.

Said tone color commutation circuit comprises the tone color switch key, and said acoustic pickup is positioned at the string below, and the tone color switch key is positioned at the back lower place of acoustic pickup.

The utility model installs a synthesis effect processor chip additional through the side at the electroacoustic guitar, it respectively with acoustic pickup, tone color commutation circuit; Be connected with audio decoder, the string sound wave of acoustic pickup transfers electric energy to, is transported to chip and closes look; Switch tone color by the tone color commutation circuit through chip, chip carries out effect process to sound signal, is handled by the audio decoder chip and links audio frequency output; Play back again through player, when therefore wanting to switch tone color, do not need to add in addition external effect device.

One feed circuit are arranged on the synthesis effect processor chip, can adopt the common batteries power supply, make outage also can normally play.

LED display can correctly show the duty of synthesis effect processor chip.

The utility model is compared with existing electroacoustic guitar, and following effect is arranged:

1, the multifunctional integrated formula electroacoustic of the utility model guitar in the time of need changing tone color for the electroacoustic guitar when playing at the scene, does not need other external effect device, can directly use the built-in synthesis effect processor of this multifunctional integrated formula electroacoustic guitar to play.

2, the synthesis effect processor of the multifunctional integrated formula electroacoustic of the utility model guitar mainly is an embedded synthetic effect chip on electroacoustic guitar side panel in the past, and has power supply, uses one piece of 9V battery, has omitted cover feed circuit, and is simple and convenient.

3, the space of the present invention's right hand capable of using; No longer switch tone color completely with pin; Switch the back lower place (to scroll head) of tone color key at acoustic pickup, required tone color can be conveniently switched in the performance so no matter orientation of each on platform can both be incisively and vividly.

4, the inner commercially available synthesis effect processor chip of the multifunctional integrated formula electroacoustic of the utility model guitar the is integrated repertoire of external effect device has in the past avoided connecting because of external effect device unfavorable factors such as loaded down with trivial details fault that causes and interference.

The multifunctional integrated formula electroacoustic of the utility model guitar is different from general traditional electroacoustic guitar, is multi-functional being integrated in one or perfect electronic musical instrument, uses when being highly suitable for band's rehearsal and on-the-spot performance, when playing, can reach perfect playing effect.
