Description

Technical Field

[0001] The present invention relates to the field of vibration simulation technology, in particular to an integrated modular touch simulation vibration device. Background Art

[0002] Touch simulation devices usually have vibration generating devices installed inside the device, such as motors, speakers, eccentric wheels (rotor motors) driven by motors, linear motors, piezoelectric vibration motors, etc. When these devices realize touch simulation, the hardware is driven by software, so that the quantified and digitized vibration information can be correctly transmitted to the hardware to realize vibration simulation. For example, a game controller with a vibration function is connected to a game console, and the software in the console controls the motor in the game controller to generate vibration, so that explosions, shootings, the material of the road surface where the game character walks, driving a car on different roads, touching objects of different properties, etc., or interactive feedback, can all be simulated through vibration and transmitted to the hands with rich sensory nerves. Provide players with a real experience with a sense of presence, and provide a content experience of touch in addition to vision and hearing.

[0003] However, traditional devices for sensing vibration information have the following disadvantages:

[0004] At present, there are few types of devices that provide vibration information and they are limited. In the field of console games and PC games, only game controllers with vibration motors have vibration functions. In the field of music creation, such devices do not exist. For example, if an expansion module is a MIDI pad, the pad is a tool for music creators to input percussion instrument signals to computers or other MIDI devices. However, when creators use pure pads, they cannot experience the real feeling brought by percussion instruments.

[0005] Insufficient device integration. Different rotor motors and linear motors can provide different vibration experiences. At present, mobile phones basically only have one linear motor integrated inside, and game controllers usually only have two rotor motors of different sizes, which are insufficient in terms of the richness of tactile information and force scale that can be simulated.

[0006] The product has a single application area. Usually, the motor installed on a device is only used in one area. For example, a game controller is only used to play games, instead of a product that can be used in multiple areas in a modular way to save resources. Summary of the invention

[0007] The purpose of the present invention is to provide an integrated modular touch simulation vibration device to solve the problem that at present, there are few types of devices that provide vibration information and they have limitations as mentioned in the above background technology.

For example, if one expansion module is a MIDI pad, the pad is a tool for music creators to input percussion instrument signals into computers or other MIDI devices. However, when creators use pure pads, they cannot experience the real sense of the percussion instrument.

It is a strong positioning and weak connection mechanism, which can be used for basic fixation of maintenance and debugging of products. At the connection between the product base and the upper cover, there is a positioning ring on the base with an outer diameter equal to the inner diameter of the upper cover.

The fitting top is located on the four edges of the upper part of the upper cover, so there is a fitting top on the edge of each side of the upper part of the upper cover.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. For the first time, the scene vibration simulation system is integrated into a device as a single concept, and a modular expansion method is used to realize different multi-modal vibration simulation functions in multiple demand fields. This concept and expansion method are both the contents claimed for protection by this patent;

[0018] 2. Use multi-axis and multi-form, including eccentric rotor motor, linear motor, and original brushless motor-driven rotor eccentric integrated motor array to simulate the vibration with richer, more delicate and faster response;

[0019] 3. The response mode of the linear motor group wheel start. Since the linear motor has a resonant frequency, the strongest vibration volume (amplitude) provided by the frequency outside this frequency will drop rapidly as it moves away from the resonant frequency. The response mode of the group wheel start, that is, when the response frequency required by the vibration content under the premise of maintaining a specific vibration volume exceeds the range of the vibration frequency that the motor can maintain at this specific vibration volume, the motor will be immediately grouped, the wheel group will respond, and the complementary vibration in the stop range will be performed to achieve frequency compensation. It can be divided into up to four groups, and the highest response frequency is increased to four times that of a single motor of the same specification;

[0020] 4. Motor anti-stepping distribution equivalent vibration strategy. Because the linear motor has a heavy counterweight, there is a certain startup delay and a long disconnection and return time in the instantaneous response due to mechanical inertia. The main control of this patent requires that when the vibration information of a motor arrives, the displacement of the counterweight caused by the last time has not been returned and cannot be started within the time length that the user can perceive. The main control will adopt an automatic distribution plan to transmit this vibration to the nearest startable motor for vibration;

[0021] 5. Differential wave conduction design: the material filled inside the shell of the present invention contacts the motor to achieve vibration transmission to the shell surface, so as to achieve high-volume vertical vibration transmission and reduce horizontal wave conduction; realize left and right hand partition vibration, and weaken the mechanical wave transmitted from the left area to the right area;

[0022] 6. Strong positioning base and upper cover buckle group. The main device is a box-shaped device in appearance. It has several interfaces, including at least two USB Type-C universal serial interfaces for charging and exchanging information with the computer, and a 5-pin contact communication interface. The main device shell is divided into three parts: base, upper cover, and fitting top. After disassembly, the interior consists of a battery pack, a composite multi-axial vibration motor array, a component bracket, a shell support and fixing bracket, threaded holes, a main control board, multiple types of motors, and filling materials;

[0023] 7. By integrating the motor array, control system, interface, communication solution, and power supply solution into a shell, switching different uses through expansion module connection, and realizing the simulation of vibration information for users through the collaborative work of multiple types of motor arrays, the vibration quantity and information richness upper limit that can be provided by the present invention will be much higher than the existing vibration simulation devices on the market. It is a new form of vibration simulation device.

[0024] The present invention uses the expansion keyboard module to simulate the touch of the game scene with multiple types of motors, giving players an immersive experience; by expanding the MIDI percussion pad module to simulate the vibration of percussion instruments, creators of electronic contemporary music creation can also experience the good feedback experience of traditional real instrument recording creators when creating. At the same time, the modular design of the present invention allows users to switch between multiple functions in more than the two application scenarios listed above, so that a set of hardware can be used for different scenarios and different functions, with high application efficiency.
