    摘要: An electronic device has an electrically adjustable shutter. The shutter may be placed in a transparent state or a nontransparent state. The shutter may overlap a portion of a display, may overlap a liquid contact indictor or a structure with text in a device, or may overlap an optical component such as an optical proximity sensor, ambient light sensor, visible light-emitting diode or laser, infrared light-emitting diode or laser, visible light image sensor, or infrared light image sensor. Control circuitry in the electronic device may place the shutter in an opaque state to hide an overlapped component from view or may place the shutter in a transparent state to allow the overlapped component to transmit or receive light. The adjustable shutter may exhibit changes in its transmission spectrum in different modes of operation and may be used as a camera filter or neutral density filter.

    摘要: An electronic device has an exterior housing with a piezoelectric speaker disposed in an opening formed within the housing. The piezoelectric speaker includes a speaker diaphragm that is secured within the opening with a vibration isolator. The vibration isolator allows the diaphragm to vibrate independently from the housing.

    摘要: A mobile phone may include a housing. The housing may include a first housing component including a cladding portion formed from a first metal and defining a first portion of a side exterior surface of the mobile phone, and a core portion coupled to the cladding portion, the core portion defining a portion of an interior surface of the mobile phone and formed from a second metal different from the first metal, a second housing component defining a second portion of the side exterior surface of the mobile phone, and a joint structure coupled to the first housing component and the second housing component and defining a third portion of the side exterior surface of the mobile phone between the first portion of the side exterior surface and the second portion of the side exterior surface. The cladding portion may be bonded directly to the core portion.
