Description

Brush drive device

The invention relates to a driving device, in particular to a brush drive device for a music player.

Generally speaking, in order to create a specific atmosphere in a specific occasion, such as creating a lively atmosphere at a party, DJs will push the vinyl record on the record player with their hands to control the rotation or steering of the record to adjust The playback speed or repeat playback of the clip music; in addition, the volume can be adjusted to produce special music effects and create a lively atmosphere.

With the development of the times, one of the current mainstream methods of storing music is to store music as an audio file in a digital signal format. Users can use an audio player to read and directly play the audio file stored in it, or Use the audio player to read audio files externally connected to another device (such as a mobile phone or hard drive) to play music.

Therefore, in order for the DJ to still be able to simulate the operating experience of pushing a vinyl record while controlling the audio player, an analog turntable can also be installed on the current audio player. During the process of playing music, the analog turntable is driven at the same time; when the DJ moves the analog turntable with the rhythm of the music, the analog turntable will slow down or rotate in the opposite direction, and its rotational state is converted into an electrical signal and transmitted to the audio player. The main body of the machine is used to control the music that plays the corresponding special music effects.

Because the DJ can move the analog turntable in accordance with the rhythm of the music, he can be more immersed in the music and boost the atmosphere of the scene. Therefore, developing an easy-to-operate and durable driving device that can simulate the feel of brushing a vinyl record is one of the goals of continuous research by people in the technical field.

Therefore, it is an object of the present invention to provide a brush disk driving device that can overcome at least one disadvantage of the prior art.

Audio player 90. In this embodiment, the second light sensor 82 is connected to the circuit board 112 using a signal line, and the signal is connected to the audio player 90 .

When in use, the motor 312 is powered on and rotates and drives the turntable 32 to rotate synchronously. With the friction provided by the wear-resistant pads 331, the scraper assembly 53 rotates synchronously with the turntable 32. At this time, the scraper mold Group 5 is in this linked state. When a user (not shown), such as a DJ, applies force to brush the scraper assembly 53 diagonally downward, the scraper assembly 53 will also be affected by the downward thrust, and will not move in conjunction with the turntable 32 At this time, the scraper module 5 and the turntable 32 rotate at different speeds. In particular, through the arrangement of the wear-resistant pads 331, the user can smoothly brush the scraper assembly 53 to slow down the rotation speed of the scraper assembly 53, pause the rotation, or rotate in the opposite direction.

Therefore, the user can use the scratching plate assembly 53 as a simulated turntable, and the scratching action produces a scratching feel similar to operating a traditional vinyl record.

In addition, the scraper module sensor 8 senses the rotational state of the scraper module 5 and transmits the change signal of the rotational state to the central processing system (not shown) inside the audio player 90 to When the audio player 90 plays an audio file in a digital format, it can produce corresponding special changing sound effects. Since the above-mentioned technology of converting the rotational state into the corresponding special change sound effect is well known to those with ordinary knowledge in the technical field, it will not be described in detail here.

To sum up, the new brush plate driving device 10 of the present invention utilizes the design that the axial bearing 4 is disposed between the base 1 and the turntable module 3 in the axial direction A, and the axial bearing 4 is in The stress on the upper components in the vertical direction is relatively even, which can improve the overall durability of the device and help increase the service life of the device. Furthermore, by utilizing the design of the shaft barrel 2, the first rotating shaft 311 and the second rotating shaft 51 are respectively located at the bottom and top of the shaft barrel 2. When the transmission line group 63 is a cable, the transmission line group 63 can be appropriately expanded. The predetermined inner diameter of the shaft barrel 2 allows the transmission line set 63 to be directly inserted into the audio player 90 through the shaft barrel 2, thus saving time and convenience in assembly. In addition, by utilizing the design of the first magnetic component 522 and the second magnetic component 532, the scraper assembly 53 can be easily removed from the scraper lower seat 52 or sucked back, making disassembly and assembly very convenient. The novel and innovative design can indeed achieve the purpose of this new model.

However, the above are only examples of the present invention, and should not be used to limit the scope of the present invention. All simple equivalent changes and modifications made based on the patent scope of the present invention and the content of the patent specification are still within the scope of the present invention. Within the scope covered by this new patent.
