Referring to fig. 4, the frame 111 includes a plastic frame 1111 and a metal frame 1112, the metal frame 1112 is disposed outside the plastic frame 1111, the plastic frame 1111 and the middle plate 112 are integrally formed by injection molding, and the middle plate 112 is made of metal or plastic. In this embodiment, the metal frame 1112 is an appearance member of the frame 111, and can provide a metal appearance texture to improve the overall texture of the electronic device 100. Meanwhile, the plastic frame 1111 can play a good role in buffering, so as to improve the anti-falling performance of the electronic device 100. In addition, the plastic frame 1111 and the middle plate 112 are integrally formed by injection molding, which not only has simple process and low cost, but also has stable overall structure of the middle frame 110, so as to provide stable support for structural members such as the battery 120 or the motherboard in the electronic device 100.

As shown in fig. 5 and 8, the middle plate 112 is provided with a first wire passing groove 111a, the vibration element 130 is spaced from the bottom wall of the first wire passing groove 111a to form a gap, and at least a part of the first leveling section 151 is accommodated in the first wire passing groove 111a, so as to reduce the stacking thickness of the middle plate 112 and the first leveling section 151 in the thickness direction of the electronic device 100, and thus the electronic device 100 is light and thin.

The side wall of the mounting groove 110b close to the vibrating assembly 130 is provided with a clearance groove 111b, and the bending section 152 is accommodated in the clearance groove 111b, so that the battery 120 in the mounting groove 110b is prevented from being scratched by the bending section 152 to damage the electric core of the battery 120, and the use safety of the battery 120 is effectively ensured.

Further, in the first direction, the depth of the clearance groove 111b is equal to the thickness of the bent section 152, so that the bent section 152 is compactly disposed between the middle plate 112 and the battery 120 and does not scratch the battery 120.

As shown in fig. 5, 8 and 9, the vibration assembly 130 includes a bracket 131 and a motor 132, the bracket 131 is connected to the middle plate 112, and the motor 132 is connected to the bracket 131. The bracket 131 is used to connect the motor 132 with the middle plate 112, so that a space for arranging the first leveling section 151 is formed between the bracket 131 and the middle plate 112, and at the same time, the bracket 131 can ensure the installation stability of the motor 132, so that when the electronic device 100 performs a vibration prompt, the vibration of the motor 132 in the working state can be transmitted to the middle frame 110 by the bracket 131, so that a user can obtain a vibration feeling.

Further, the vibration assembly 130 includes a back adhesive layer 133, and the motor 132 is connected to the bracket 131 through the back adhesive layer 133.

In some embodiments, the bracket 131 is made of stainless steel or 7-series aluminum alloy, so that the bracket 131 has sufficient structural strength, so that the motor 132 can directly drive the middle plate 112 to vibrate through the bracket 131, and the bracket 131 cannot vibrate relative to the middle plate 112, thereby reducing the noise generated by the forced vibration of the bracket 131 when the motor 132 transmits vibration to the middle frame 110 through the bracket 131.

A damping piece 1321 is disposed between the bracket 131 and the middle plate 112, and the first leveling section 151 and the damping piece 1321 do not overlap with each other, so that the vibration of the bracket 131 relative to the middle plate 112 is suppressed by the damping piece 1321.

Further, the number of the damping pieces 1321 is 2 or more than 2, and the damping pieces are respectively located at two sides of the first leveling section 151 in the first direction, so that when the motor 132 vibrates, vibration energy transmitted to the middle plate 112 by two sides of the bracket 131 is consistent, the vibration effect is improved, and no vibration stress is generated on the first leveling section 151, so as to maintain the electrical performance of the flexible circuit board 150.

The damping sheet 1321 includes at least one of a PET (Polyethylene terephthalate) tape and a silicone sheet. Such a damping piece 1321 has a good damping effect to suppress the bracket 131 from vibrating against the middle plate 112 due to the vibration of the motor 132.

As shown in fig. 11, one side of the damping sheet 1321 may have an adhesive layer 1322 to be coupled between the bracket 131 and the middle plate 112 through the adhesive layer 1322, which is simple to assemble, and may realize pre-fixing of the bracket 131 and the middle plate 112 so as to couple the bracket 131 and the middle plate 112 with the screw 130 b.
