Abstract
Improved approaches for providing a speaker within a housing of a portable electronic device are disclosed. The housing of the portable electronic device can be compact, such as a low profile housing. In one embodiment, an acoustic chamber for a speaker can be formed internal to a housing for a portable electronic device using non-dedicated space. In another embodiment, irregular surfaces can be sealed so that an acoustic chamber for a speaker can be formed internal to a housing for a portable electronic device.
Claims33
A portable electronic device, comprising:
- a housing;
- a speaker provided in said housing;
- a back volume for said speaker, said back volume being formed from an area within said housing that is not dedicated to said back volume;
- and
- a front volume for said speaker, said front volume being formed from an area within said housing that is not dedicated to said front volume.
A portable electronic device, comprising
- a printed circuit board;
- electrical components mounted on said printed circuit board;
- an EMI shielding structure attached to said printed circuit board, said EMI shielding structure be provided over one of more of said electrical components;
- a speaker attached to said EMI shielding structure;
- and
- a form-in-place seal used to at least in part form an acoustic chamber for said speaker.
A method for assembling a portable electronic device having an internal acoustic back volume, said method comprising:
- obtaining a printed circuit board;
- attaching electrical components to the printed circuit board;
- attaching an EMI shielding can to the printed circuit board such that the EMI shielding can is placed over one or more of the attached electrical components;
- attaching a speaker to the EMI shielding can;
- applying a form-in-place sealant to one or more particular locations of the assembled printed circuit board;
- curing the form-in-place sealant;
- and
- thereafter assembling the portable electronic device such that the assembled printed circuit board is provided within a housing of the portable electronic device and such that the internal acoustic back volume is formed within the portable electronic device housing and coupled to the speaker.
A portable electronic device, comprising
- a housing;
- electrical components provided within said housing;
- an internal structure provided within said housing;
- a speaker provided within said housing and attached to said internal structure;
- and
- a form-in-place seal provided within said housing, said form-in-place seal being used to at least in part form an acoustic chamber for said speaker.
