Description

TECHNICAL FIELD

The present disclosure relates to the technical field of electronic products, and in particular, to an electronic device, a key assembly, and a key control method.

BACKGROUND

Most existing key structures on automobiles, keyboards and the like devices are conventional mechanical pressing structures having a large pressing stroke, and an elastic member (for example a spring) is used inside. The elastic member generates deformation and an inverse process when being subjected to an external force (for example, a finger pressing force), so that a user's finger feels press feedback. However, the inventors have found that at least the following problems exist in the related art: the existing key structure directly induces press feedback by finger pressing, which is very mechanic and clumsy; the user can only feel vibration feedback through one type of operation (i.e., pressing); and therefore, the key can only enable the corresponding electronic device to implement one type of function (for example, only the delete function), such that the user cannot control the electronic device through the key to achieve multiple functions, and the different needs of the user cannot be met.

The processor is configured to, when receiving the sensed data, acquire a vibration mode corresponding to the sensed data, and control the linear motor to vibrate according to the vibration mode.

The user confirms whether the corresponding operation is completed according to the vibration feedback so that the user can control the electronic device to achieve a variety of functions through different operations on the key, making it convenient for the user to control the electronic device.

A third embodiment of the present disclosure relates to a key control method applied to a processor of an electronic device in the second embodiment. As shown in FIG. 3, the key control method includes the following steps.

In step 101, an operation of a user on a key housing is sensed by a sensing element, and sensed data is generated.

In this embodiment, the sensing element is disposed on a surface of the key housing, and the key housing is disposed on a base through an elastic member.

In one example, the sensing element may be a pressure sensor or a capacitive sensing element. The embodiment does not impose any limitation on the type of the sensing element, which may be set according to actual needs.

In one example, the sensed data includes one or any combination of pressure information, a touch area, a number of touch points, a sliding direction and a number of touches of the operation by the user. The embodiment does not impose any limitation on the type of the sensed data.

In step 102, a vibration mode corresponding to the sensed data is acquired.

In this embodiment, a preset correlation between the sensed data and the vibration mode is pre-stored in the processor. Therefore, the processor acquires the vibration mode corresponding to the sensed data according to the sensed data and the preset correlation between the sensed data and the vibration mode.

In this embodiment, the vibration mode includes one or a combination of the vibration intensity and the number of vibrations. The embodiment does not impose any limitation on the vibration mode.

In step 103, a linear motor mounted on the key housing is controlled to vibrate according to the vibration mode to cause the key housing to generate corresponding vibration feedback in response to the vibration of the linear motor.

In the present embodiment, the operation of the user on the key housing, the vibration mode, and the vibration feedback correspond to each other.

The embodiment of the present disclosure provides a key control method for controlling a key assembly provided by the embodiment of the present disclosure. That is, when an operation of a user on a key housing is sensed by a sensing element, the sensing element generates sensed data, acquires a vibration mode corresponding to the sensed data, and controls a linear motor to vibrate according to the vibration mode, so that the key housing generates corresponding vibration feedback in response to the vibration of the linear motor. That is, the embodiment of the present disclosure can generate vibration feedback for a corresponding operation according to different operations of the user. The user confirms whether the corresponding operation is completed according to the vibration feedback, so that the user can control the electronic device to achieve various functions by different operations on the key, thereby making it convenient for the user to control the electronic device.

A fourth embodiment of the present disclosure relates to a key control method. The fourth embodiment is improved on the basis of the third embodiment. The main improvement is that in the fourth embodiment of the present disclosure, a method of acquiring the vibration mode is provided.

The key control method of the present embodiment is as shown in FIG. 4. Steps 201 and 203 of the present embodiment are the same as steps 101 and 103 of the first embodiment, and step 202 of the present embodiment includes the following sub-steps.

In sub-step 2021, a pressure level of the pressure is identified from the pressure information.

In the present embodiment, when the sensed data is the pressure information, this step is performed. Moreover, a preset correlation between the pressure and the pressure level is pre-stored in the processor. One pressure level corresponds to a plurality of pressure values. In this embodiment, the pressure of the user's operation is identified from the pressure information. The pressure level corresponding to the pressure is identified according to the preset correlation.

In sub-step 2022, a vibration mode corresponding to the pressure level is acquired according to a preset correlation between the pressure level and the vibration mode.

In the present embodiment, when the vibration mode is vibration intensity, the preset correlation is a preset correlation between the pressure level and the vibration intensity. Different vibration intensities control the electronic device to achieve a function of the corresponding intensity. When the vibration mode is the number of vibrations, the preset correlation is a preset correlation between the pressure level and the number of vibrations. Different numbers of vibrations control the electronic device to achieve the function for a corresponding number of times.

In one example, the pre-stored pressure level includes level 1 pressure and level 2 pressure. The level 1 pressure corresponds to level 1 vibration intensity. The level 2 pressure corresponds to level 2 vibration intensity. When the pressure level of the pressure is identified as level 2 pressure, the vibration intensity corresponding to the level 2 pressure is acquired as the level 2 vibration intensity. However, this is merely an exemplary explanation, which is not limited in practice.

Compared with the third embodiment, in the embodiment of the present disclosure, when the sensed data is pressure information, the pressure level of the pressure is identified from the pressure information, and a vibration mode corresponding to the pressure level is acquired according to a preset correlation between the pressure level and the vibration mode, which provides a method of acquiring the vibration mode.

A fifth embodiment of the present disclosure relates to a key control method. The fifth embodiment is improved on the basis of the third embodiment. The main improvement is that in the fifth embodiment of the present disclosure, a method of acquiring the vibration mode is provided.

The key control method of the present embodiment is as shown in FIG. 5. Steps 301 and 303 of the present embodiment are the same as steps 101 and 103 of the first embodiment, and step 302 of the present embodiment is as follows.

In sub-step 302, a vibration mode corresponding to the number of touch points is acquired.

In the present embodiment, when the sensed data is the number of touch points, this step is performed. Further, in the present embodiment, a preset correlation between the number of touch points and the vibration mode is pre-stored.

In one example, the vibration mode is the number of vibrations. It is preset that a single-point touch corresponds to one vibration, and a multi-point touch corresponds to two vibrations. When the number of touch points is two, the acquired corresponding vibration mode is two-vibration. This is merely an illustrative explanation, which is not limited in practice.

Compared to the third embodiment, in the embodiment of the present disclosure, when the sensed data is the number of touch points, a vibration mode corresponding to the number of touch points is acquired, that is, another method of acquiring the vibration mode is provided.

A person skilled in the art can understand that the above embodiments are specific embodiments for implementing the present disclosure, and various changes can be made in the form and details without departing from the spirit and scope of the present disclosure.
