Description

Technical Field

[0001] The utility model belongs to the technical field of sound playback, and in particular relates to a sound playback demonstration device. Background Art

[0002] Sound waves are the propagation form of sound, a kind of mechanical wave, generated by the vibration of an object. In real life, we can use recording and playback equipment to record and play sound, but we cannot intuitively know how the sound fluctuations are generated, nor how the sound is recorded. The sound recording equipment we used before had a recording point that was too small, and we could not intuitively observe the phenomenon of sound being recorded. Utility Model Content

[0003] The purpose of the utility model is to provide a sound playback demonstration device, aiming to solve the problem that the prior art cannot intuitively know how the sound fluctuations are generated, nor how the sound is recorded. The sound recording equipment we used before has a recording point that is too small, making it impossible to intuitively observe the sound being recorded.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sound playback demonstration device, which is composed of a drum, a hammer, a bracket, a spring, a sound recording device and a motor. A hammer is arranged above the drum, and the hammer is rotatably mounted on the bracket. A spring is connected between the bracket and the hammer, and the other end of the hammer is mounted on the sound recording device. The sound recording device includes a waveform recorder and a guide rail, and the guide rail is installed below the waveform recorder. The motor is installed on the fixed frame.

[0005] As a further solution of the present invention, the sound recording device is a rectangular parallelepiped.

[0006] As a further solution of the utility model, the waveform recorder is two sets of tracks that are adjustable up and down.

[0007] As a further solution of the utility model, the waveform recorder is of an adjustable tightness type.

[0008] As a further solution of the utility model, the output shaft of the motor is connected to a sound recording device.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] When the utility model is performing sound recording, firstly, a hammer is placed on the upper surface of the waveform recording device of the sound recording device, and the motor is turned on. The waveform recording device is struck with an auxiliary hammer. At this time, since the waveform recording device of the sound recording device is relatively loose, the striking process will be recorded on the waveform recording device. When playing back the sound, firstly, a hammer is placed on the lower surface of the waveform recording device of the sound recording device, and then the waveform recording device is tightened, and then the motor is turned on. Since there is a waveform in the waveform recording device, the striking process will be simulated to play back the sound, so that the entire process of sound recording and playback can be intuitively observed.

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] Example

[0016] See also Figure 1 The utility model provides the following technical solutions: a sound playback demonstration device, which consists of a drum 1, a hammer 2, a bracket 3, a spring 4, a sound recording device and a motor 8. A hammer 2 is arranged above the drum 1, and the hammer 2 is rotatably mounted on the bracket 3. A spring 4 is connected between the bracket 3 and the hammer 2. The other end of the hammer 2 is mounted on the sound recording device. The sound recording device is a rectangular parallelepiped. The sound recording device includes a waveform recorder 5 and a guide rail 6. The waveform recorder 5 is two sets of tracks that can be adjusted up and down. The waveform recorder 5 is of an adjustable tightness type. A guide rail 6 is installed below the waveform recorder 5. A motor 8 is installed on the fixing frame 7. The output shaft of the motor 8 is connected to the sound recording device.

[0017] The working principle and use process of the utility model are as follows: when recording sound, firstly place the hammer on the upper surface of the waveform recorder of the sound recording device, turn on the motor, and use the auxiliary hammer to hit the waveform recorder. At this time, since the waveform recorder of the sound recording device is loose, the hitting process will be recorded on the waveform recorder. When playing back the sound, first place the hammer on the lower surface of the waveform recorder of the sound recording device, then tighten the waveform recorder, and then turn on the motor. Since there is a waveform in the waveform recorder, the hitting process will be simulated to play back the sound.
