Abstract

This application relates to three-dimensional seals for buttons. More specifically, a button assembly including a watertight seal and a method of manufacturing the same are provided. The button assembly may include a button made of a rigid material having a trim and a stem. The stem may extend from the bottom surface of the button and may activate a switch of the electronic device when said button is actuated. Furthermore, the button assembly may include a sealing member made of a soft material having a stem receiving hole. The sealing member may be fixed to the button and the inner surface of the housing of the electronic device. A stem receiving aperture may fit around and engage the stem. In some embodiments, the button can include a cavity, and the sealing member can include a protruding member. In these embodiments, the cavity may receive a protruding member to provide better positioning of the sealing member and button during assembly.

Description

Background technique [0001] The invention relates to a button assembly for electronic equipment, in particular to a waterproof seal for the button in the electronic equipment and a manufacturing method thereof. [0002] One common way for users to provide input to electronic devices, such as portable media players and cellular telephones, is through the use of buttons. A switch (eg, a dome switch or a push-button switch) is typically mounted behind the button and activates the switch when the user actuates the button. When activated, the switch implements an electrical circuit and can provide electrical signals to other components of the electronic device. [0003] In some applications, it is beneficial for the button assembly to have a watertight seal in order to prevent liquids from entering the electronic device and contacting the internal components of the device. For example, if a user mistakenly pours liquid on an electronic device, the liquid can sometimes contact the...
