In order to explain the technical solution of the present invention, the following detailed description is made with reference to the specific drawings and examples.

Referring to fig. 1, an embodiment of the present invention provides a key structure 1 for being mounted on an installation main body 2 and further being used in an electronic device such as a speaker. In the present embodiment, the key structure 1 is used to control an audio device and the like. Of course, the key structure 1 may also be used in other suitable electronic devices.

With further reference to fig. 2, the key structure 1 includes a circuit board 11, key contacts 12, and a soft rubber cover 13. Wherein, the number of the key contact 12 is at least one, and the key contact is arranged on the circuit board 11. The soft rubber cover 13 covers the circuit board 11. Specifically, the soft rubber sleeve 13 includes a first soft rubber layer 131 correspondingly covering the key contact 12 and a second soft rubber layer 132 extending from two ends of the first soft rubber layer 131, and the first soft rubber layer 131 and the second soft rubber layer 132 are integrally formed.

Obviously, the embodiment of the utility model provides an in the utility model provides a button structure 1, cover on circuit board 11 through integrated into one piece's first soft glue layer 131 and second soft glue layer 132 in with the soft gum cover, compare in current button structure 1, this button structure 1's simple structure, when reaching waterproofly, because this soft gum cover 13 has certain elasticity, can bear and transmit load, therefore, this button structure 1 can give certain cushioning effect when receiving external force vibration, avoid the mutual vibration between button structure 1 and the installation main part 2. Furthermore, when the loudspeaker is used in a sound box, the phenomenon that the components collide with each other or rub each other due to the fact that the air flow pressure in the cavity impacts the key structure 1 when the loudspeaker works normally in a closed space can be prevented, and therefore noise is generated.

In one embodiment, the first soft adhesive layer 131 and the second soft adhesive layer 132 are integrally formed and made of the same material, so that the one-step molding is facilitated. Specifically, the first soft rubber layer 131 and the second soft rubber layer 132 are both made of soft plastic materials, such as soft plastic materials with certain elasticity, toughness and hardness, such as silicone rubber. Of course, in practice, the materials of the first soft adhesive layer 131 and the second soft adhesive layer 132 may be different.

In an embodiment, further referring to fig. 3, the upper surface of the first soft adhesive layer 131 is higher than the upper surface of the second soft adhesive layer 132, and a first groove 1311 is formed inside the first soft adhesive layer 131 to form a deformation space. The first groove 1311 ensures that the soft rubber sleeve 13 can give a certain buffering effect when receiving external force vibration, and avoids the vibration of other components from being transmitted to the key structure 1, thereby causing mutual collision or friction between the components in the key structure 1. In addition, since the first soft adhesive layer 131 covers the key contacts 12, and the first soft adhesive layer 131 has certain elasticity, the first groove 1311 also provides a certain elastic expansion space, so that the key contacts 12 can be conveniently touched by hands, and the hand feeling of the key is increased to a certain extent.

In the present embodiment, in order to further press the key contacts 12 well, the inner surface of the first soft adhesive layer 131 is in contact with the upper surfaces of the key contacts 12. Here, "in" inner surface "means in the vicinity of the first recess 1311, and" up "in" upper surface "means in the direction away from the circuit board 11. It can be understood that, by setting the inner surface of the first soft adhesive layer 131 to be in contact with the upper surface of the key contact 12, the user can press the key contact 12 by directly contacting the first soft adhesive layer 131 without giving a certain external force, so that the first soft adhesive layer 131 is elastically pressed down to be in contact with the key contact 12.

Of course, in other embodiments, the inner surface of the first soft adhesive layer 131 may be higher than the upper surface of the key contact 12, so as to avoid misoperation. The selection can be made according to actual requirements.

In one embodiment, a second recess 1321 is formed in the second soft adhesive layer 132, and the height of the second recess 1321 is higher than the height of the circuit board 11. Through seting up second recess 1321 in second soft glue layer 132, also can give certain deformation space for this button structure 1 can provide certain buffer capacity when receiving external force, further avoids the impact between button structure 1 and the installation main part 2.

Of course, in other embodiments, the height of the second recess 1321 may be set flush with the height of the circuit board 11 as long as a certain deformation space can be given.

In an embodiment, further referring to fig. 2, a flange 133 for matching with the mounting body 2 is disposed around the second soft adhesive layer 132, and by disposing the flange 133, a double-sided adhesive is added on one side of the flange 133, so as to facilitate attaching the entire key structure 1 to the mounting body 2. Specifically, the flange 133 is ring-shaped, the double-sided tape is 3M double-sided tape, and the 3M double-sided tape is manufactured by 3M company, and is widely used in products such as computers, mobile phones, communication, home appliances, and audio-visual devices.

note that, in order to attach the entire key structure 1 to the mounting body 2, the width of the flange 133 is in a range of 3mm to 5 mm. This width ensures that the flange 133 can be stably attached to the mounting body 2, and if it is too narrow, it is likely to fall off, and if it is too wide, it is likely to occupy a space of the mounting body 2. Specifically, the shape of the circuit board 11 is an elongated shape, and therefore, the flexible rubber sleeve 13 covering the circuit board 11 is also an elongated shape, where the "width of the flange" refers to a direction along the width of the circuit board 11.

The utility model also provides an electronic equipment, please refer to fig. 1 and fig. 2, and this electronic equipment includes the equipment main part, and the outside of equipment main part is equipped with the button structure 1 described for above-mentioned arbitrary embodiment, and the equipment main part is installation main part 2 described for above-mentioned embodiment.

In one embodiment, in order to facilitate mounting the circuit board 11, the main body of the device extends toward the circuit board 11 with a plurality of mounting posts 21, and the circuit board 11 is correspondingly provided with mounting holes 110 for mating with the mounting posts 21.

Specifically, mounting holes 110 are respectively formed at two ends of the circuit board 11, the mounting holes 110 are further formed between every two key contacts 12 on the circuit board 11, and the mounting holes 110 are respectively arranged in one-to-one correspondence with the mounting posts 21, so that the circuit board 11 can be stably fixed on the device body while the circuit board 11 is accurately positioned.

In the present embodiment, in order to stably mount the circuit board 11 on the device main body without shaking due to an external force, a double-sided tape is added to the back surface of the circuit board 11, and then the circuit board is assembled to the device main body.

In one embodiment, the electronic device is an audio device, the main body of the device is an audio device main body, and the audio device main body is provided with a mounting groove 22 for mounting the key structure 1.

the above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
