[0035] Please refer to Figure 1 The present invention provides a buffer-type vibration device for vibration feedback, comprising:

[0036] A vibration generating component, the vibration generating component includes a transducer element 10 capable of generating mechanical vibration under the action of an electrical signal;

[0037] The buffer assembly includes an elastic buffer element 23 connected to the vibration generating assembly. The elastic buffer element 23 is bent in at least two dimensions to buffer vibrations through its own deformation when the vibration generating assembly is working.

[0038] In this embodiment, by providing a specially shaped elastic buffer element 23 within the vibration device, the impact force generated during the vibration process is effectively buffered, making the key vibration softer, avoiding the discomfort caused to the user's hand by harsh vibration, and significantly improving the user's comfort when operating the electronic device. It is understandable that because the elastic buffer element 23 curves in at least two dimensions, it effectively reduces the impact of vibration on the vibration device itself and the external structures connected to it, reducing the risk of structural damage caused by long-term vibration, extending the service life of the vibration device and the entire electronic device, and thus reducing the maintenance costs and resource waste caused by equipment failure or damage.

[0039] In addition, the elastic buffer element 23 is made of metal, which can better adjust the amplitude and frequency changes of vibration during the vibration process, which helps to improve the reliability of the device in different usage environments.

[0040] In this embodiment, the vibration generating assembly further includes a first support plate 11 and a second support plate 12 respectively arranged on both sides of the transducer element 10. The two ends of the first support plate 11 and the second support plate 12 are respectively fixedly connected to the transducer element 10, thereby playing the role of stably supporting the transducer element 10.

[0041] The first support plate 11 is provided with a fixing plate 21 for fixing with an external device, so as to facilitate the installation of the entire vibration device at a corresponding position of the electronic device. The second support plate 12 is provided with a buffer component.

[0042] In this embodiment, the first support plate 11 and the second support plate 12 are both arched structures. The ends of the first support plate 11 and the second support plate 12 are tightly fitted with the transducer element 10, and the middle portions of the first support plate 11 and the second support plate 12 respectively protrude outwardly away from the transducer element 10 to form a gap between them and the transducer element 10. This arched structure allows the support plates to better adapt to the deformation of the transducer element 10 during vibration, while also providing suitable space and elasticity for the generation and transmission of vibration.

[0043] Furthermore, the transducer element 10 is a piezoelectric ceramic. Piezoelectric ceramics have good electromechanical conversion performance and can generate precise mechanical vibrations under the drive of electrical signals, meeting the requirements of the vibration device for the vibration source.

[0044] In this embodiment, the buffer assembly includes an elastic sheet 22 connected to the second support sheet 12 , and an elastic buffer element 23 is connected to the elastic sheet 22 .

[0045] The elastic buffer element 23 is a sheet-like structure, which has two forms:

[0046] Please refer to Figure 1 One is to bend in a circuitous manner within the plane where the fixing plate 21 is located. This form increases the buffer distance through a complex bending path within the plane, and can effectively disperse the impact force when the vibration propagates in the direction of the plane;

[0047] Please refer to Figure 2 The other is a double convex profile with periodic undulations, forming a wavy structure protruding outward on both sides of the elastic sheet 22. This three-dimensional wavy structure can buffer the vibration impact force in the direction perpendicular to the plane, making the buffering effect more comprehensive.

[0048] Furthermore, metal sleeves 13 are respectively provided at both ends of the vibration generating assembly. The metal sleeves 13 are fitted over the first support plate 11, the second support plate 12, and the transducer element 10, and are bonded and fixed to the first support plate 11, the second support plate 12, and the transducer element 10. The provision of the metal sleeves 13 enhances the structural stability of the vibration generating assembly and prevents the components from loosening or shifting during vibration.

[0049] Furthermore, the fixing plate 21 is provided with holes, slots or snap-fit structures for installation, so as to facilitate a stable connection with an external device.

[0050] Furthermore, the elastic buffer element 23 is connected to the vibration generating component by means of socketing, gluing or riveting, so as to ensure a reliable connection between the two, effectively transmit vibration and realize a buffering function.

[0051] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concepts of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
