Technical field

[0001] The present invention relates to the technical field of handheld devices, and in particular to a tactile feedback structure of a handheld device. [Background Technology]

[0002] Buttons are press-activated control devices, critical components for controlling product functions and widely used across a wide range of product categories. Traditional buttons require a certain amount of pressure to deform a built-in spring, generating a reverse spring force to provide tactile feedback. This results in a monotonous tactile experience and lacks a rich tactile experience. To address this pain point, tactile solutions have emerged on the market that use motor vibration to replace physical buttons. However, the vibration of these buttons is dispersed, failing to achieve a concentrated tactile feedback within the key area. This significantly reduces their practicality and limits their application in various scenarios.

[0003] Therefore, it is necessary to provide a new handheld device to solve the above technical problems.

[0004] [Summary of the invention]

[0005] An object of the present invention is to provide a handheld device with a concentrated vibration area for tactile feedback and diversified vibration sensations.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a handheld device, comprising a shell provided with an opening, a button accommodated in the shell and partially extending out of the shell from the opening, a sensor connected to the button for detecting the pressed state of the button, a chip electrically connected to the sensor, a vibration motor arranged on a side of the sensor away from the button, and an elastic connecting member, wherein a suspension structure composed of the button, sensor, and vibration motor is connected to the shell through the elastic connecting member.

[0007] Preferably, the shell forms a wall surrounding the opening and is spaced apart from the button.

[0008] Preferably, the elastic connecting members are a pair, one end of each elastic connecting member is connected to the vibration motor, and the other end is fixed to the shell.

[0009] Preferably, the handheld device further comprises a connecting block provided between the vibration motor and the elastic connecting member, and the elastic connecting member is connected and fixed to the vibration motor via the connecting block.

[0010] Preferably, the connecting block is a plastic block or a metal block.

[0011] Preferably, the connecting block is fixed to the elastic connecting member or the vibration motor by gluing or welding.

[0012] Preferably, the elastic connecting member includes a first connecting portion partially connected to the connecting block and a second connecting portion horizontally bent and extended from the first connecting portion to connect to the shell, and both the first connecting portion and the second connecting portion are sheet-like structures.

[0013] Preferably, the button includes an extension portion having a size smaller than that of the opening and a stop portion having a size larger than that of the opening.

[0014] Preferably, the vibration direction of the vibration motor is perpendicular to the pressing direction of the button.

[0015] Compared with related technologies, the handheld device provided by the present invention includes a shell with an opening, a button housed in the shell and partially extending out of the shell from the opening, a sensor connected to the button to detect the pressed state of the button, a chip electrically connected to the sensor, a vibration motor disposed on the side of the sensor away from the button, and an elastic connector. The suspension structure formed by the button, sensor, and vibration motor is connected to the shell via the elastic connector. In the handheld device of the present invention, the button structure can produce a variety of tactile effects, providing tactile feedback of different frequencies, different durations, and different vibration times in different scenarios. The design of the suspension structure formed by the button, sensor, and vibration motor concentrates the tactile feedback in the button area, retaining the function of the physical button and making the application of the button more diverse.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Please refer to Figures 1-4 at the same time. The present invention provides a handheld device 100, which includes a shell 1 with an opening 11, a button 2 accommodated in the shell 1 and partially extending out of the shell 1 from the opening 11, a sensor 3 arranged below the button 2, a chip 4 arranged in the shell 1 and electrically connected to the sensor 3, a vibration motor 5 arranged on the side of the sensor 3 away from the button 2, and an elastic connecting member 6.

[0022] A receiving space 10 is formed in the housing 1 . The opening 11 is provided on a side of the housing 1 and communicates with the receiving space 10 . The housing 1 includes a surrounding wall 12 surrounding the opening 11 .

[0023] The button 2 is partially accommodated in the receiving space 10 and partially extends out of the shell 1 from the opening 11. The button 2 includes an extension portion 21 having a size smaller than the size of the opening 11 and a stop portion 22 having a size larger than the size of the opening 11. The extension portion 21 extends out of the shell 1 from the opening 11, and the stop portion 22 limits the length of the extension portion 21 extending out of the shell 1. The height of the extension portion 21 is greater than the height of the stop portion 22. The shape of the extension portion 21 matches the shape of the opening 11, and the extension portion 21 is spaced apart from the surrounding wall 12 forming the opening 11, that is, the extension portion 21 of the button 2 does not contact the shell 1, so that the button 2, sensor 3, and vibration motor 5 constitute a suspended structure suspended in the shell receiving space 10.

[0024] The sensor 3 may be a pressure sensor, which is connected to the button 2 to detect the pressing state of the button 2. The pressing state includes whether there is a pressing action, the strength of the pressing, and the duration of the pressing.

[0025] The chip 4 is electrically connected to the sensor 3 and the vibration motor 5. When the button 2 is pressed, the sensor 3 recognizes the pressing information, including the pressing time and force, and sends an electrical signal to the chip 4. The chip 4 then sends a corresponding preset vibration signal to the vibration motor 5 based on the received pressing information, causing the vibration motor 5 to vibrate according to the preset vibration signal to provide tactile feedback.

[0026] The vibration direction of the vibration motor 5 is perpendicular to the pressing direction of the button 2 , or the vibration direction of the vibration motor 5 is parallel to the pressing direction of the button 2 . Preferably, the vibration direction of the vibration motor 5 is perpendicular to the pressing direction of the button 2 .

[0027] The suspension structure composed of the button 2, sensor 3, and vibration motor 5 is connected to the shell 1 through the elastic connector 6. The elastic connector 6 is a pair, and one end of each elastic connector 6 is connected to the vibration motor 5, and the other end is fixed to the shell 1. Specifically, the elastic connector 6 includes a first connecting portion 61 that is partially connected to the vibration motor 5 and a second connecting portion 62 that is horizontally bent and extended from the first connecting portion 61 and connected to the shell 1. The first connecting portion 61 and the second connecting portion 62 are both sheet-like structures. Due to the flexible effect of the elastic connector 6, the inertial force of the vibration is concentrated on the suspension structure, so that people can feel a locally concentrated vibration when touching the button 2.

[0028] The elastic connector 6 can be directly connected to the vibration motor 5 or indirectly fixed to the vibration motor 5. Preferably, in this embodiment, the handheld device 100 also includes a connecting block 7 arranged between the vibration motor 5 and the elastic connector 6. The connecting block 7 is fixed to the end of the first connecting portion 61 of the elastic connector 6, and the elastic connector 6 is connected and fixed to the vibration motor 5 through the connecting block 7. The connecting block 7 is a plastic block or a metal block, or is made of other harder materials. The connecting block 7 can be fixed to the elastic connector 6 or the vibration motor 5 by gluing or welding. For example, if the connecting block 7 is made of plastic material, it is fixed to the elastic connector 6 or the vibration motor 5 by gluing; if the connecting block 7 is made of metal material, it is fixed to the elastic connector 6 or the vibration motor 5 by gluing or welding.

[0029] In the present invention, since the vibration motor 5, the sensor 3 and the button 2 are connected as a whole to form a suspended structure, the vibration motor 5 will drive the button 2 to vibrate together. Due to the suspension effect of the elastic connector 6 and the position setting of the suspension structure, the tactile effect generated by the vibration is concentrated in the button area, and the vibration sense is concentrated. At the same time, changing the preset vibration signal can make the button 2 produce different tactile effects, which can be applied to different application scenarios, bringing richer application effects, and greatly enhancing practicality.

[0030] Compared with related technologies, the handheld device provided by the present invention includes a shell with an opening, a button housed in the shell and partially extending out of the shell from the opening, a sensor connected to the button to detect the pressed state of the button, a chip electrically connected to the sensor, a vibration motor disposed on the side of the sensor away from the button, and an elastic connector. The suspension structure formed by the button, sensor, and vibration motor is connected to the shell via the elastic connector. In the handheld device of the present invention, the button structure can produce a variety of tactile effects, providing tactile feedback of different frequencies, different durations, and different vibration times in different scenarios. The design of the suspension structure formed by the button, sensor, and vibration motor concentrates the tactile feedback in the button area, retaining the function of the physical button and making the application of the button more diverse.

[0031] The above is only an embodiment of the present invention. It should be pointed out that those skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements are all within the scope of protection of the present invention.
