[ detailed description ] embodiments

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 4, the present embodiment provides a dual-color mode key.

This embodiment includes button soft casing 1 and button stereoplasm inner shell 2, button soft casing 1 and button stereoplasm inner shell 2 mould plastics integrated into one piece by the double-colored mould, button soft casing 1 on be equipped with button function sign 11, button stereoplasm inner shell 2 on be equipped with the button hole 21 that corresponds with button function sign 11 and be located the button piece 22 in the button hole, button piece 22 on be equipped with the elastic arm 23 of connecting button piece 22 and button hole 21 inner wall. According to the double-color-mold key provided by the embodiment, the soft key outer shell and the hard key inner shell are integrally formed by adopting a double-color-mold injection molding technology, the soft key outer shell provides comfortable hand feeling for a user, meanwhile, the hard key inner shell provides structural support for the soft key outer shell, when the double-color-mold key is used, only the key function mark on the soft key outer shell is pressed, after the key block in the hard key inner shell is stressed and pressed to a corresponding metal sheet in the control chip to complete key operation, the elastic arm fixedly connected with the key block in the hard key inner shell drives the key block to rebound and recover the original state, so that the whole key is not easy to dent and deform, and the durability of the key is improved; moreover, the integrated into one piece's structure can not produce the clearance between button and shell, plays fine dustproof and waterproof function, has greatly promoted customer experience.

Furthermore, the number of the elastic arms 23 is two, the two elastic arms 23 are respectively arranged at two ends of the key block 22, when pressure is applied to the key block 22, the elastic arms 23 at the two ends can be uniformly stressed to drive the key block 22 to rebound, and the elastic structure is stable.

Furthermore, the key block 22 is located in the center of the key hole 21 and has a fitting gap 24 with the key hole 21, one end of the elastic arm 23 is fixedly connected with the key block 22, the other end of the elastic arm 23 extends along the outer contour of the key block 22 in the fitting gap 24 and is finally fixedly connected with the inner wall of the key hole 21, a first gap 241 is formed between the extension section of the elastic arm 23 and the key hole 21, and a second gap 242 is formed between the extension section of the elastic arm 23 and the key block 22. As shown in fig. 1, in this embodiment, the elastic arms 23 at the two ends of the key block 22 are arranged in a "Z" shape, the second gap 242 formed between the extending section of the elastic arm 23 and the key block 22 is correspondingly arranged in a "Z" shape, and the first gap 241 formed between the elastic arm 23 and the key hole 21 is arranged in an arc shape. With the structure, the elastic arm 23 can partially fill the fit gap 24, and the influence of the depression caused by the shrinkage deformation of the region opposite to the key hole 21 in the soft key shell 1 due to the overlarge fit gap 24 on the user experience is prevented.

Further, the widths of the first gap 241 and the second gap 242 are both 1 mm. The 1mm gap width is beneficial to reducing the shrinkage deformation of the area opposite to the key hole 21 in the soft shell 1 of the key, so that the structure of the key is more stable.

Furthermore, the thickness of the elastic arm 23 at the connection end of the elastic arm 23 and the key hole 21 is smaller than the thickness of the elastic arm 23 at the connection end of the elastic arm 23 and the key block 22, and the adoption of the structure with the local thickness reduced is beneficial to the elasticity of the elastic arm 23.

Furthermore, a key bump 221 is disposed at one end of the key block 22 away from the soft key housing 1. When pressure is applied to the key block 22, the key bumps 221 on the key block 22 can be conveniently contacted with the metal sheet on the control chip to complete the key operation.

Furthermore, the soft shell 1 of the key is made of TPU or TPE. The TPU is named as thermoplastic polyurethane elastomer rubber, the strength is high, the wear resistance is good, and the durability of the bicolor mold key made of the TPU is high; the TPE is a thermoplastic elastomer material, has the performances of high elasticity, aging resistance and oil resistance, and the bicolor mold key made of the TPE material has comfortable hand feeling and good customer experience. In addition, as shown in fig. 2, the soft key outer shell 1 is provided with a connecting hole 12 at one end of the hard key inner shell 2, which is beneficial to preventing the soft key outer shell 1 from being pulled high during demolding, so that the molding of the double-color mold key is more delicate and the quality is higher.

Furthermore, the key hard inner shell 2 is made of PC + ABS or ABS material. The ABS has good comprehensive performance, high impact strength and good chemical stability, is a tough, hard and rigid material with wide application, and the PC and ABS material combines the formability of the ABS material and the mechanical property, the impact strength, the temperature resistance, the ultraviolet resistance and other properties of the PC, so that the ABS has good comprehensive performance and high impact strength, and the PC, the ABS or the ABS material can be adopted to ensure that the structure of the key hard inner shell 2 is more stable.

Further, the number of the key function identifiers 11 is three, and the three key function identifiers are respectively a volume plus key 111, a volume minus key 112 and a switch function key 113, and the switch function key 113 is arranged between the volume plus key 111 and the volume minus key 112. As shown in fig. 1, in this embodiment, the volume plus key 111 is shown by a "+" key, the volume minus key 112 is shown by a "-" key, and the switch function key 113 is shown by an ellipse with a gentle and prominent coaxial center, so that the key function identifier is simple, and is convenient for users to understand and use.

This embodiment still provides an earphone, and this earphone has above-mentioned double-colored mould button, makes the whole more exquisite durable of earphone, not only dustproof and waterproof, feels better moreover, has greatly promoted customer experience.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
