Description

Game drum

The present invention relates to a game drum, and more particularly to a game drum including a microelectromechanical pressure sensing module.

With the booming game industry, the demand for input devices for inputting operational information to game consoles has also increased. Conventional input devices, such as game console drums, use pressure sensing elements, such as capacitive films, to simulate the force exerted by the player in the game in a manner that strikes the rubber drumhead. The game drum will generate a signal of 0 and 1 depending on whether it is subjected to pressure, and the signal will be input to the host of the game drum to control the force applied in the game. However, the input device cannot accurately know the magnitude of the pressure, and the sensitivity is low, and the reliability is poor, which affects the player's performance in the game project.

In view of this, it is necessary to provide a game drum to instantly know the magnitude of the player's exertion and to improve the player's participation in the game.

Hereinafter, the embodiment will be taken as an example to illustrate a game drum that can instantly know the magnitude of the player's force.

A game drum includes a drum body having a receiving cavity, a pressure sensing module disposed in the receiving cavity, a pressure capsule and an output interface. The pressure sensing module includes a processing unit, a power supply unit that supplies power to the processing unit, and a microelectromechanical pressure sensor. The pressure capsule is coupled to the MEMS pressure sensor for sensing the pressure The pressure experienced by the bladder translates the pressure into a pressure sensing signal. The pressure sensing signal is transmitted to the processing unit. The processing unit is configured to calculate a pressure value of the pressure capsule according to the pressure sensing signal. The output interface is connected to the processing unit for connecting to the terminal device, so that the user can know the pressure value by using the terminal device.

The game drum uses a high-sensitivity pressure sensing module to instantly measure the pressure of the pressure capsule, so that the player can immediately know the force exerted, improve the player's performance, and further stimulate the player to participate in the game.

The force receiving surface 271 is connected to the inner side wall of the drum body 21 to close the receiving cavity 211. The fixing surface 272 is provided with an opening (not shown). The pressure bladder 27 is made of a material having elastic deformation ability. In the present embodiment, the pressure bladder 27 is made of rubber. When When the force surface 271 of the pressure bladder 27 is hit, the pressure bladder 27 will be compressed by pressure while generating an air flow at its opening. When the pressure disappears, the pressure bladder 27 resumes deformation.

The pressure sensing module 22 includes a micro electromechanical pressure sensor 221, a processing unit 222, a wireless transmission unit 223, a power supply unit 224, a control unit 225, and a DC to DC power conversion unit 226.

The microelectromechanical pressure sensor 221 uses a microelectromechanical system for pressure measurement, which may be a piezoresistive microelectromechanical pressure sensor or a capacitive microelectromechanical pressure sensor and other types of microelectromechanical pressure sensors. The MEMS system refers to a micro-electromechanical system that integrates a miniature sensor, an actuator, and a signal processing and control circuit, a interface circuit, a communication, and a power supply. The MEMS pressure sensor 221 is housed in the receiving cavity 211, which is in contact with the fixing surface 272 of the pressure bladder 27 and seals the opening of the pressure bladder 27. The microelectromechanical pressure sensor 221 carries the entire pressure bladder 27. Once the pressure bladder 27 is compressed by the pressure, the airflow generated at the opening directly acts on the MEMS pressure sensor 221. The MEMS pressure sensor 221 is configured to acquire the pressure applied by the pressure capsule 27 and convert the pressure value into a sensing signal representing a pressure, and the sensing signal is a digital signal. The MEMS pressure sensor 221 and the processing unit 222 are electrically connected by a data transmission channel (not shown). The sensing signal is transmitted to the processing unit 222 via the data transmission channel.

The processing unit 222 can be a micro processing unit or a dedicated integrated circuit for calculating the pressure of the pressure capsule 27 according to the received sensing signal. The wireless transmission unit 223 is electrically connected to the processing unit 222. Data transmission is possible between the wireless transmission unit 223 and the processing unit 222. The wireless transmission unit 223 is for transmitting data to the control unit 225 or receiving data from the control unit 225. The power supply unit 224 supplies power to the wireless transmission unit 223 and the processing unit 222. A DC to DC power conversion unit 226 may be further disposed between the power supply unit 224 and the processing unit 222. By DC to DC power conversion unit 226 The voltage of the power supply unit 224 is converted to a voltage suitable for the processing unit 222. In this embodiment, the wireless transmission unit 223 is a Bluetooth transmission unit, and the power supply unit 224 is a battery pack.

The control unit 225 is for recording and storing the pressure value transmitted by the wireless transmission unit 223, and controlling the operation of the display device 23.

This embodiment employs the display device 23 as a terminal device. The display device 23 and the drum body 21 including the pressure sensing module 22 are prepared and used simultaneously.

At this time, the force receiving surface 271 of the pressure bladder 27 does not close the receiving chamber 211. The striking wall is attached to the force receiving surface 271 and closes the receiving cavity 211. When the striking wall is struck, the striking wall transmits the force it receives to the force receiving surface 271 of the pressure bladder 27, whereby the pressure bladder 27 is compressed, and at the opening thereof, acts on the MEMS pressure. The air flow of the detector 221. Alternatively, the pressure bladder 27 can be plural. At this time, the MEMS pressure sensor 221 can be correspondingly set to a plurality or a single number. However, all of the openings of the pressure bladder 27 must be sealed by the microelectromechanical pressure sensor 221. Further, the pressure capsule 27 can be disposed directly on the side of the microelectromechanical pressure sensor 221 near the pressure bladder 27 without the opening, and when the pressure capsule 27 is compressed by force, it transmits the pressure to the micro.
