Description

Technical Field

[0001] The utility model relates to the technical field of sound boxes, in particular to a pedal-type electric guitar sound box. Background Art

[0002] Electroacoustic instruments, such as the electric guitar, electric bass guitar, and electric erhu, evolved from acoustic instruments. They do not have an acoustic resonance chamber structure, so they cannot produce a sound loud enough to meet the requirements of the performance environment. However, they have their own transducers that convert the vibrations of the instrument strings or diaphragms into electrical signals. Only after the transducer is output to an external device for amplification can a satisfactory sound effect or volume be achieved.

[0003] These external devices can be divided into two categories by type. The first category: front-end effects processors (such as the GEMBOX II digital guitar multi-effects processor), which can be implemented in either analog or digital form. There are many types of effects processors, and their primary function is to adapt the input electric instrument signal to the front-end impedance and frequency response, and to add additional audio processing to achieve the desired sound effect. However, these products only have effects processing functions, and the output power is generally only sufficient to drive headphones. To achieve a sufficiently loud sound, the signal must be further amplified.

[0004] The second category: amplifiers that can perform front-end sound processing on the signal (such as the 5150III split guitar speaker) and amplify the processed signal to obtain sufficient volume. This type of product generally appears in the form of a dedicated speaker for some kind of electro-acoustic instrument, such as guitar speakers, saxophone speakers, erhu speakers, etc.

[0005] Both of the above-mentioned two types of products can correctly process the signals of electro-acoustic instruments and obtain the correct instrument timbre; however, the functions or characteristics of the two products will be somewhat unsuitable in the situations where performers usually practice. For example, the first type of products must be connected to an external power amplifier or plugged into headphones to hear a loud enough sound when practicing at home. The second type of products are very large and weigh dozens of kilograms. They cannot be carried outdoors or when traveling. When practicing at home, their volume is often too loud to cause disturbance to others.

[0006] For home practice or travel practice scenarios, various speaker manufacturers have designed smaller portable speakers to meet the needs of players practicing at home or while traveling. These products integrate front-end effect processing circuits suitable for electric instruments and have low-power sound amplification capabilities. The volume is appropriate and will not cause disturbance to others during home practice, such as the JA-02II portable electric guitar speaker.

[0007] Although the above-mentioned speakers are highly portable and can correctly process and amplify the signals of electro-acoustic instruments, they do not have the ability to connect an external control pedal, so channel switching can only be done manually. In other words, the performer must interrupt the current performance and switch to the desired channel to obtain the appropriate sound before continuing to practice.

[0008] The speaker, patented with ZL201520692529.4, has three pre-amplifier signal processing channels and two control pedals integrated into the speaker casing. Users can switch between desired tone channels without interrupting performance, solving the problem of portable speakers having to switch channels manually. However, there are still limitations on the number of available effects. Utility Model Content
