Abstract

The invention discloses a durable resilient mobile phone external volume key which comprises a mobile phone and an external key. The side of the mobile phone is provided with a mounting groove. A volume increasing control area and a volume reducing control area are symmetrically arranged at the bottom of the mounting groove. The bottom, which is close to the side wall, of the mounting groove is a receiving surface. Insertion pieces are symmetrically arranged on the receiving surface. Each insertion piece is a rectangular piece. Each insertion piece is hollow inside. A fixed shaft is arranged in each insertion piece. The outer side of each insertion piece is symmetrically connected with first elastic pieces at intervals. Each first elastic sheet is triangular. The first elastic pieces are fixedly connected with the insertion pieces. According to the invention, the external key is improved by improving the side of a blind mobile phone; the external key is waterproof, is prevented from protruding, and is stably arranged; the external key is prevented from stressing a volume control area in the case of ordinary collision; a pressing elastic member is prevented from being stuck; and the durable resilient mobile phone external volume key is especially for blind people to use.

Description

technical field [0001] The invention relates to the technical field of mobile phones for the blind, in particular to a rebound-type external volume key for durable mobile phones. Background technique [0002] The mobile phone for the blind generally refers to a mobile phone specially designed for the blind in terms of functional operation. A mobile phone specially produced for the blind. All functions of the mobile phone can be output in the form of voice, and the blind can perform corresponding operations through the information given by the voice system, including sending short messages. A screen voice navigation software is installed on some ordinary mobile phones equipped with a certain smart phone system platform, so that the blind can operate part or all of the functions on the mobile phone. The software needed by individuals is more popular with the blind. [0003] Existing external volume keys of mobile phones are mostly protruding settings, and such a design metho...
