Description

[0002] With the development of display technology, many display circuits are usually integrated on a remote controller (such as a capacitive touch remote controller, etc.), such as a display screen and logic function indicator lights, etc. Since the power consumption of the display circuit is relatively high, the battery life of the remote controller is relatively poor. Therefore, more and more remote controllers use low-power display screens, or use low-power LED dual-eight displays instead of display screens to reduce power consumption, but the battery life of the remote controller is still not long enough.

[0003] Currently, in order to extend the usage time, some remote controllers will enter the sleep state when not in use for a long time and will be woken up when the touch button is pressed again. However, when the user cannot see the buttons on the remote controller clearly, it is very inconvenient to wake up the remote controller, resulting in a poor user experience. Utility Model Content

[0025] In order to be able to more clearly understand the above-mentioned objects, features, and advantages of the present disclosure, the solution of the present disclosure will be further described below. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0026] Numerous specific details are set forth in the following description to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all the embodiments.

[0027] Figure 1 The following is a schematic structural diagram of a vibration wake-up circuit provided for an embodiment of the present disclosure. As Figure 1 shown, the vibration wake-up circuit includes: a controller 120, a vibration switch 110, and a signal optimization processing circuit 130. The signal optimization processing circuit 130 is respectively connected to the controller 120 and the vibration switch 110; the controller 120 is configured to output an original signal, wherein the level value of the original signal is a first level; the vibration switch 110 is configured to switch the switch state between open and closed in response to a user's vibration operation, so as to switch the level value of the original signal between the first level and a second level to become a pulse signal; the signal optimization processing circuit 130 is configured to perform optimization processing on the pulse signal.

[0028] Specifically, the controller 120 is capable of outputting an original signal, and the level value of the original signal is a first level. In one example, the first level is a high level, and correspondingly, the second level is a low level. In another example, the first level is a low level, and correspondingly, the second level is a high level.

[0029] Optionally, the controller 120 may include an MCU, but is not limited thereto. It can be understood that the MCU has advantages such as low power consumption and high reliability. Selecting the MCU as the controller 120 can achieve effects such as reducing power consumption and improving reliability.

[0030] Specifically, the vibration switch 110 is capable of switching the switch state in response to a user's vibration operation.

[0031] Among them, the vibration operation can be any operation that can cause the vibration switch 110 to switch its switch state. For example, operations such as making the remote control vibrate, displace, or accelerate, which can be specifically embodied as the user picking up, shaking, or tapping the remote control, etc., but are not limited thereto.

[0032] In some examples, in response to a user's vibration operation, the vibration switch 110 can switch from an open state to a closed state. In other examples, in response to a user's vibration operation, the vibration switch 110 can switch from a closed state to an open state. The present disclosure does not limit this.

[0033] The following describes the typical structure of the vibration switch 110, but does not constitute a limitation to the present disclosure.

[0034] Optionally, the vibration switch 110 includes a steel ball and a metal conductive layer, and a first contact and a second contact are provided on the metal conductive layer.

[0035] Specifically, the vibration switch 110 includes a freely moving steel ball and a metal conductive layer, and a first contact and a second contact are provided on the metal conductive layer. In some examples, when the vibration switch 110 senses external vibration, the internal steel ball will roll between the first contact and the second contact, so that the first contact and the second contact come into contact, forming a circuit, and the vibration switch 110 closes. In the absence of vibration, the steel ball returns to its original position, the first contact and the second contact separate, the first contact and the second contact are disconnected, and the vibration switch 110 is disconnected. Therefore, the vibration switch 110 can switch its switch state according to whether there is vibration. Of course, in some examples, it can also be that when the vibration switch 110 senses external vibration, the internal steel ball will roll to its original position, the first contact and the second contact separate, the first contact and the second contact are disconnected, and correspondingly, in the absence of vibration, the steel ball will be located between the first contact and the second contact, so that the first contact and the second contact come into contact.

[0036] In some examples, when the vibration switch 110 switches from the off state to the on state, the level value of the original signal can be switched from the first level to the second level, and the original signal becomes a pulse signal. Correspondingly, when the vibration switch 110 switches from the on state to the off state, the level value of the original signal can be switched from the second level to the first level. In other examples, when the vibration switch 110 switches from the on state to the off state, the level value of the original signal can be switched from the first level to the second level, and the original signal becomes a pulse signal. Correspondingly, when the vibration switch 110 switches from the off state to the on state, the level value of the original signal can be switched from the second level to the first level.

[0037] Exemplarily, when the user does not perform a vibration operation, the vibration switch 110 can remain in the off state. When the user performs a vibration operation, in response to the user's vibration operation, the vibration switch 110 can switch from the off state to the on state, so that the level value of the original signal is switched from a high level to a low level, and the original signal becomes a pulse signal. When the user stops the operation, the vibration switch 110 switches from the on state to the off state again, so that the level value of the original signal is switched from a low level to a high level.

[0038] Specifically, the signal optimization processing circuit 130 can optimize the pulse signal.

[0039] Optionally, the signal optimization processing circuit 130 includes a filtering circuit, a frequency selection circuit, and / or a debouncing circuit, but is not limited thereto.

[0040] It can be understood that an unoptimized pulse signal is usually a messy and irregular signal. Through optimization processing, the pulse signal can be filtered, frequency - selected, and / or debounced to obtain a regular pulse signal in a preset frequency band. In this way, the accuracy of vibration wake - up can be improved.

[0041] Specifically, when the controller 120 detects a pulse signal, that is, when it detects that the level value of the original signal switches from the first level to the second level, it can wake up the remote control to implement the vibration wake - up function.

[0042] Those skilled in the art should understand that the pulse signal generated by the vibration wake - up circuit can not only be used for the wake - up function, but also be used in instruments such as vibration detection, displacement, and automation systems.

[0043] In the embodiment of the present disclosure, the controller 120 can output an original signal with a level value of the first level. The vibration switch 110 can respond to the user's vibration operation to switch the switch state, so as to switch the level value of the original signal from the first level to the second level, becoming a pulse signal. The signal optimization processing circuit 130 can optimize the pulse signal. The processed pulse signal can replace the touch signal in the prior art to implement the wake - up function. In this way, for the remote control provided with this vibration wake - up circuit, in the sleep state, the user can wake up the remote control by vibration operations such as picking up, shaking, or tapping the remote control. The wake - up method is very convenient and is conducive to the convenient use of power saving of the remote control.

[0044] Figure 2 FIG. [FIGURE NUMBER] is a schematic structural diagram of another vibration wake - up circuit provided by the embodiment of the present disclosure. Figure 3 FIG. [FIGURE NUMBER] is a circuit element diagram of a vibration wake - up circuit provided by the embodiment of the present disclosure. As Figure 2 and Figure 3 shown, the signal optimization processing circuit 130 includes a filtering and frequency - selecting circuit and a debouncing circuit. Specifically, the signal optimization processing circuit 130 includes a resistor R and a capacitor C; the first end of the resistor R is connected to the controller 120, and the second end of the resistor R is connected to the first contact 1 of the vibration switch 110; the first end of the capacitor C is connected to the first contact 1 of the vibration switch 110, and the second end of the capacitor C is connected to the second contact 2 of the vibration switch 110, and the second contact 2 of the vibration switch 110 is grounded.

[0045] Specifically, the capacitor C and the resistor R constitute a filtering and frequency - selecting circuit, and at the same time, the capacitor C is also a debouncing circuit.

[0046] The filtering and frequency - selecting circuit can filter and frequency - select the pulse signal, which helps to remove the interference in the pulse signal.

[0047] The debounce circuit can perform debounce processing on pulse signals. Specifically, when the vibration switch 110 is vibrated, the capacitor C starts to charge or discharge, and this process has a certain delay. The specific time is determined by the resistance value multiplied by the capacitance value, and this delay time is greater than the jitter time (generally from a few milliseconds to dozens of milliseconds), so that the level value of the original signal remains unchanged before the switch state of the vibration switch 110 stabilizes, thus effectively filtering out the jitter signal.

[0048] In some examples, the resistor R is a fixed resistor.

[0049] In other examples, the resistor R includes a variable resistor. That is, the resistance value of the resistor R is adjustable.

[0050] Optionally, the variable resistor includes a wire-wound variable resistor or a digital variable resistor. But it is not limited to this.

[0051] Specifically, when the variable resistor includes a wire-wound variable resistor, the user can adjust its resistance value by means such as sliding a dial, and the adjustment method is simple and convenient.

[0052] Specifically, when the variable resistor includes a digital variable resistor, the user can adjust its resistance value through the controller 120, which is beneficial to achieve precise adjustment.

[0053] In some examples, the capacitor C is a fixed capacitor. But it is not limited to this.

[0054] In other examples, the capacitor C includes a variable capacitor. That is, the capacitance value of the capacitor C is adjustable.

[0055] Optionally, the variable capacitor includes an air variable capacitor, a ceramic variable capacitor, or a thin-film variable capacitor.

[0056] Specifically, its capacitance value can be adjusted by means such as a manual knob or screw adjustment, and the adjustment method is simple and convenient.

[0057] Specifically, when the user hopes for a lower sensitivity to reduce the risk of accidental touch, the resistance value of the variable resistor can be increased and / or the capacitance value of the variable capacitor can be increased. Correspondingly, when the user hopes for a higher sensitivity, the resistance value of the variable resistor can be decreased and / or the capacitance value of the variable capacitor can be decreased.

[0058] It can be understood that by setting the variable resistor and / or the variable capacitor, the user can flexibly adjust the sensitivity of the vibration wake-up function by adjusting the resistance value and / or the capacitance value.

[0059] Continue to refer to Figure 3 , a resistor can also be connected between the resistor R and the controller 120, and the level value of the original signal can be detected through this resistor, etc.

[0060] Next, in combination withFigure 3 The principle of vibration wake-up is described in detail. As Figure 3 shown, the controller 120 is an MCU. The controller 120 includes a preset pin (such as pin 27), and the preset pin is used for interrupt wake-up. The vibration switch 110 is a highly sensitive sensor. It detects vibration operations through steel balls, and the contact resistance R between the first contact 1 and the second contact 2 causes continuous on-off changes in the high and low resistance values, thereby causing high and low level changes at the preset pin of the MCU. Among them, when the vibration switch 110 is stationary, it is usually in an open state. When it receives operations such as vibration, tilt, and movement, it can switch to a closed state, and the preset pin changes from a high level to a low level, generating a pulse signal. After the pulse signal is screened, filtered, and debounced by a filtering and frequency selection circuit and a debouncing circuit, a pulse signal in a preset frequency band is obtained. This preset frequency band pulse signal serves as an interrupt signal. After being detected by the preset pin of the MCU, the MCU can perform a wake-up action, thereby achieving the effect of head-up display.

[0061] The present disclosure also provides a remote controller, which includes the vibration wake-up circuit provided in any embodiment of the present disclosure.

[0062] Specifically, the remote controller may further include a display circuit.

[0063] Specifically, the remote controller may be a capacitive touch remote controller, etc., but is not limited thereto.

[0064] Exemplarily, in the application of power saving of the remote controller, the head-up display function is used in a more user-friendly scenario. When the user does not use the remote controller, the remote controller is in a sleep state. When a vibration operation such as vibration, displacement, and acceleration is applied to the remote controller, the vibration wake-up circuit outputs a corresponding pulse signal, which can quickly wake up the remote controller and enter the working state to achieve the purpose of power saving.

[0065] It should be noted that since the remote controller includes a vibration wake-up circuit, the remote controller provided in the embodiments of the present disclosure has the same or corresponding technical effects as the vibration wake-up circuit, which will not be elaborated here.

[0066] It should be noted that in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements that are inherent to such process, method, article, or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the said element.
