Description
Technical Field
The invention relates to the field of musical instruments, in particular to a portable bakelite drum.
Background
The current structure of electroacoustic percussion instruments generally comprises a primary piezoelectric device or other sensing devices attached to a synthetic wood (or other material) surface; sensing the force level of the attached wood or other material surface layer being knocked by the user or drummer. The amplitude/signal strength is detected by MIDI electronics, which in turn "triggers" prerecorded and stored outputs, typically stored in digital form, of the acoustic drum tone. In the prior art, a low-quality sensing device is attached to the knocking surface of the synthetic wood or the plywood, and various fine striking performances in the percussion performance cannot be reproduced by triggering the prerecorded sampling tone color output mode, so that the tone quality is poor, and the method is limited to the mode of triggering and sampling the tone color. If the sensing means is used only as a "trigger" mechanism, any background noise may occur in the band, and the listener will hear the pre-recorded color that was triggered, rather than the original signal itself that caused the "trigger" mechanism.
For example, in the prior art, the sensing device is not distinguished at all by tapping on the striking surface using a drum brush, or by tapping with a drum stick. It is more unlikely that the soothing effect of the drum will be reproduced. Other tools such as hands, feet, and sticks are not used during knocking.
In the prior art, for example, a card flood drum (Cajon) is a rectangular box, which is made of six faces, typically wooden plates, and one or more of the faces is/are attached with sensing devices. But more, one surface is provided with a round hole for placing a microphone into the pick-up; the structure of the african drum (djembe) is a drum head, a cavity and a ring for hooping the drum head on the cavity, the cavity is usually formed by digging holes in raw wood, and a product formed by injection molding of synthetic materials is also available. The bottom of an african drum is empty and if the microphone is aimed at the head, the high frequencies in the picked-up tone will be excessive, however for convenience during performance, it is often necessary to pick up sound from the head. In order to pick up low frequencies more, the microphone is extended from the bottom of the drum, so that a firm drum stand needs to be manufactured, the trouble is very high, and the African drum is not so portable; most of these instruments require a microphone to amplify the sound. Microphones tend to feed back (howl) and also tend to pick up sounds (strings) of other instruments in the vicinity, thus affecting the fidelity of the percussion instrument to some extent.
In the prior art, a low-quality and low-output induction device is used, no high-output electric signal is used for amplification, and a fine and soft percussion music performance such as jazz is required, so that the percussion music is easy to fall into noise or hissing sound in an electronic circuit. Without a high output high quality sensing device, there is not a strong enough signal source and the signal to noise ratio is low.
Disclosure of Invention
