Referring to fig. 1 and fig. 2, in a preferred embodiment, the operation assembly includes an intelligent terminal 10 and an operation accessory 20, the operation accessory 20 is a peripheral device of the intelligent terminal 10, and is sleeved outside the intelligent terminal 10, for example, a handle of the peripheral device (a full-wrapping type, a half-wrapping type, or a type that only partially wraps the intelligent terminal 10), the operation accessory 20 has an operation key 21, the operation key 21 faces outward, and a user can apply a pressing force to the operation key 21, thereby implementing an effect of pressing a mechanical entity key. In order to ensure the integrity of the housing of the intelligent terminal 10, the intelligent terminal 10 includes a main control circuit board, and the main control circuit board has a control chip and other electronic devices, so as to control the use of the intelligent terminal 10. The main control circuit board further comprises an ultrasonic sensor assembly 12, which is fixedly mounted on the main control circuit board so as to receive instructions from the control chip or send electric signals to the control chip, wherein the position of the ultrasonic sensor assembly 12 is opposite to the operation keys 21 of the operation accessory 20.
Specifically, the ultrasonic sensor component 12 includes an ultrasonic transmitter and an ultrasonic sensor, and since the ultrasonic transmitter is just opposite to the operation key 21, when the ultrasonic transmitter transmits an ultrasonic wave, the ultrasonic sensor returns to the ultrasonic sensor and is received by the ultrasonic sensor after penetrating through the housing 11 of the intelligent terminal 10 and touching the operation key 21. When the user presses the operation key 21, so that the operation key 21 moves towards the intelligent terminal 10, since the operation key 21 is closer to the ultrasonic transmitter and the ultrasonic sensor, once the operation key 21 moves towards the intelligent terminal 10, the time for returning the ultrasonic wave emitted from the ultrasonic transmitter to the ultrasonic sensor is shortened, and therefore, when the time for receiving the reflected ultrasonic wave by the ultrasonic sensor is obviously shorter than the reflection time when the ultrasonic wave is initially sent, it is detected that the operation key 21 has been pressed and triggered by the user.
The changed reflection time of the reflected ultrasonic wave enables the ultrasonic sensor to recognize the change, so as to change the output electric signal of the ultrasonic sensor, for example, a trigger signal is sent to a control chip on the main control circuit board to inform the control chip of the event that the operation key 21 is triggered.
After receiving the trigger signal, the control chip generates a trigger instruction for the event triggered by the operation key 21, and sends an expected interaction instruction after the control and operation key 21 is triggered to the display screen for displaying, such as unlocking, locking the screen, adjusting the volume, activating a mute mode, and the like.
Through the configuration, on the one hand, the use experience of the entity key effect is still provided for the user, on the other hand, because holes do not need to be formed in the intelligent terminal 10, the consistency of the shell 11 of the intelligent terminal 10 can be kept, the die sinking and manufacturing processes of the shell 11 of the intelligent terminal 10 are simplified, and the shell of the intelligent terminal 10 is integrally formed without the openings or the holes.
Further, the operation accessory 20 is hollowed out to form an inner cavity for accommodating the smart terminal 10, and when the smart terminal 10 is mated with the operation accessory 20, the housing 11 of the smart terminal 10 is in interference fit with the operation accessory 20, so that the smart terminal 10 can be stabilized in the operation accessory 20. Optionally or alternatively, the operation accessory 20 is also hollowed to form an inner cavity for accommodating the smart terminal 10, the inner cavity has a connecting element, and when the housing 11 of the smart terminal 10 is fitted with the inner cavity, the connecting element stabilizes the position of the housing 11, for example, the connecting element may be a fastener, and is engaged with a fastening hole outside the housing 11 of the smart terminal 10, or the connecting element may be a magnetic element, and the housing 11 also has a magnetic element, and after the two magnetic elements are magnetically attracted, the smart terminal 10 is stabilized in the inner cavity, or the connecting element is a locking screw, and after the locking screw is selected into the fastening hole outside the smart terminal 10, the smart terminal 10 is stabilized in the inner cavity.
The positional relationship and matching relationship between the operation key 21 and the ultrasonic sensor module 12 are not limited to any positions, that is, the operation key 21 is provided on any one of the side of the operation accessory 20 in the longitudinal direction, the back side facing away from the smart terminal 10, the front side facing the smart terminal 10, and the top or bottom side in the longitudinal direction, and correspondingly, the ultrasonic sensor module 12 is provided on any one of the inner wall of the side of the smart terminal 10 in the longitudinal direction, the front side facing the operation key 21, the back side facing away from the smart terminal 10, and the top or bottom side in the longitudinal direction.
In addition to applying an operation instruction to the smart terminal 10 using the operation keys 21, the user may directly apply an operation instruction to the smart terminal 10 using a contact (a click, a long press, a double click, or the like) of an organism such as a finger with the smart terminal 10. When the intelligent terminal 10 is directly touched by a finger, the ultrasonic wave emitted by the ultrasonic emitter is reflected by the organism and then received by the ultrasonic sensor, and the ultrasonic sensor changes the output electric signal according to the received reflected ultrasonic wave, and then generates a trigger instruction in accordance with the operation key 21. Therefore, even if the smart terminal 10 is not provided with the operation accessory 20, the integrity of the housing 11 of the smart terminal 10 can be ensured only by using a finger touch manner.
Further, since the operation button 21 is different from the ultrasonic change caused by the finger pressing, the control chip has an ultrasonic change threshold a and an ultrasonic change threshold b, the ultrasonic change threshold a corresponds to the finger touch, and the ultrasonic change threshold b corresponds to the operation button 21 trigger. When the variation of the received reflected ultrasonic wave and the initial ultrasonic wave is larger than or equal to the ultrasonic wave variation threshold value a or the ultrasonic wave variation threshold value b, the control chip generates a corresponding trigger signal. Because the two are not coexisted temporarily, the control chip is provided with a switching unit, and a user operates the switching unit to inform the control chip of a mode of using a finger to touch or operating a key 21 to trigger in the current use state, so that the ultrasonic change threshold value a or the ultrasonic change threshold value b is selected to be used.
Alternatively, to simplify the operation by the user, only the ultrasonic variation threshold a is arranged in the control chip, and the variation acts on the operation key 21. Specifically, the variation of the ultrasonic wave by the stroke of the operation key 21 is adjusted to be consistent with the variation of the direct contact of the finger (or the material, hardness, etc. of the operation key 21 may also be adjusted), and then the sensing variation of the ultrasonic sensor is consistent regardless of the triggering by using the operation key 21 or the direct contact of the finger, and when the variation of the reflected ultrasonic wave received by the ultrasonic sensor is greater than or equal to the ultrasonic variation threshold a than the initial ultrasonic wave, a trigger signal is generated.
In a preferred embodiment, the operation key 21 is a mechanical key formed by any one of plastic matching soft glue, plastic elastic wall, spring, soft glue, hot melt fixing, screw fixing and adhesive fixing, which can effectively prolong the service life of the key function, the mechanical fatigue of the traditional mechanical key of the intelligent terminal 10 is only 10 ten thousand to 100 ten thousand times, and if a user selects the key function of the operation key 21 without direct contact or the mode of direct point contact of a finger, the problem of mechanical fatigue damage does not exist.
The smart terminal may be implemented in various forms. For example, the terminal described in the present invention may include an intelligent terminal such as a mobile phone, a smart phone, a notebook computer, a PDA (personal digital assistant), a PAD (tablet computer), a PMP (portable multimedia player), a navigation device, and the like, and a fixed terminal such as a digital TV, a desktop computer, and the like. In the following, it is assumed that the terminal is a smart terminal. However, it will be understood by those skilled in the art that the configuration according to the embodiment of the present invention can be applied to a fixed type terminal, in addition to elements particularly for moving purposes.
It should be noted that the embodiments of the present invention have better practicability and are not intended to limit the present invention in any way, and any person skilled in the art may change or modify the technical contents disclosed above to equivalent effective embodiments, but all the modifications or equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention still fall within the scope of the technical solution of the present invention.
