Abstract
Mobile terminals include a housing, an electronic circuit and a speaker assembly positioned in the housing. The speaker assembly includes a first speaker positioned adjacent a first side of the electronic circuit and a second speaker positioned adjacent the first speaker on the first side of the electronic circuit. A grommet may be positioned in the housing that is configured to receive the first speaker and the second speaker and the first speaker and the second speaker are positioned in the grommet. The first speaker can be a receiver speaker and the second speaker can be a micro-speaker.
Claims31
A mobile terminal comprising:
- a housing;
- an electronic circuit positioned in the housing;
- a first speaker positioned adjacent a first side of the electronic circuit;
- a second speaker positioned adjacent the first speaker on the first side of the electronic circuit;
- a grommet positioned in the housing that is configured to receive the first speaker and the second speaker, wherein the first speaker and the second speaker are positioned in the grommet, wherein the grommet is configured to provide a seal between a front face of the first speaker and a back face of the first speaker and between a front face of the second speaker and a back face of the second speaker and wherein the housing comprises a front face including a keypad and an earpiece and wherein the first speaker and the second speaker are positioned between the electronic circuit and the front face and wherein the electronic circuit comprises a printed circuit board, the mobile terminal further comprising a first passageway acoustically coupling the front face of the first speaker to the earpiece;
- and
- a second passageway acoustically coupling the front face of the second speaker to an opening in a face of the housing remote from the earpiece, wherein the first passageway includes a first high frequency forward tuning volume adjacent the front face of the first speaker and wherein the second passageway includes a second high frequency forward tuning volume adjacent the front face of the second speaker, the mobile terminal further comprising:
- a first low frequency back tuning volume adjacent the back face of the first speaker;
- and
- a second low frequency back tuning volume adjacent the back face of the second speaker.
