Embodiment 1

[0026] Such as Figure 1-2 As shown, a touch vibration feedback device includes a panel 1 and a deformable feedback diaphragm 3 arranged on the panel 1, the feedback diaphragm 3 is fixed on the upper end of a conductive plate 4, and a coil is arranged outside the conductive plate 4 5. There is a permanent magnet 6 inside the conduction plate 4, the coil 5 is connected to the trigger signal, an electromotive force sensing unit 2 is provided in the device or a touch sensing unit 8 is provided on the feedback diaphragm, the electromotive force sensing unit 2 or the The touch sensing unit 8 is connected to the trigger signal.

[0027] In this embodiment, the touch-sensing unit 2 is a flexible touch-sensing capacitive key, and the touch-sensing capacitive key and the coupling electric field will generate parasitic capacitance. When the finger touches the touch-sensing capacitive key, the capacitance value will change, as The touch-sensing capacitive key provides a feedback signal,...

Embodiment 2

[0044] Such as image 3 As shown, a touch vibration feedback device includes a panel 1 and a deformable feedback diaphragm 3 arranged on the panel 1. The feedback diaphragm 3 is fixed on the upper end of a conductive plate 4, and a coil is arranged outside the conductive plate 4. 5. There is a permanent magnet 6 inside the conduction plate, the coil 5 is connected to the trigger signal, and the feedback diaphragm 3 is provided with a touch sensing unit 2, and the touch sensing unit is connected to the trigger signal.

[0045] In this embodiment, the feedback diaphragm 3 , the conductive plate 4 , the panel 1 and the trigger are the same as those in the first embodiment.

[0046] Such as Figure 4As shown, when there are more than one touch-sensing units and they are close together, some adjustments are made on the basis of Embodiment 1. Usually, each touch-sensing unit needs a corresponding coil to drive the vibration. In order to reduce the number of coils, multiple The adj...

Abstract

The invention relates to a touch vibration feedback device. The device comprises a panel and a deformable feedback vibrating diaphragm arranged on the panel. The feedback vibrating diaphragm is fixedat the upper end of a conduction disc. A coil is arranged outside the conduction disc, a permanent magnet is arranged in the conduction disc, the coil is in signal connection with a trigger, an electromotive force induction unit is arranged in the device or a touch induction unit is arranged on the feedback vibrating diaphragm, and the electromotive force induction unit or the touch induction unitis in signal connection with the trigger. The electromagnetic coil is used for driving the feedback vibrating diaphragm to vibrate. An electromotive force sensing unit is arranged in the device or atouch sensing unit is arranged on the feedback vibrating diaphragm. When the trigger receives an induced electromotive force or a touch signal, the coil is powered on, and the powered-on coil drives the conduction disc and the feedback vibrating diaphragm to move upwards, so that fingers of a user sense vibration feedback.

Description

technical field [0001] The invention relates to a vibration device, in particular to a touch vibration feedback device and a vibration method. Background technique [0002] At present, most vibration feedback methods on the market use eccentric motors or Taptic Engine linear motors similar to Apple mobile phones. These motors can provide relatively good vibration feedback effects, but the cost is high on some feedback devices that only require a few keystrokes to vibrate. , and the placement of the vibration motor needs to be carefully designed to achieve a better experience. [0003] In some low-cost devices or occasions where only a few key feedbacks are required, sound feedback or color and light changes are mostly used to give user feedback. If vibration feedback can be added to a device that only needs a few buttons, it will definitely bring a good user experience to the user. Nowadays, the form of touch is widely used in various electrical equipment. Touch can bring ...
