Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
88 words
A shielded electronic device that is susceptible to electromagnetic radiation or that emits electromagnetic radiation, comprising: a housing having a speaker opening and a shielding means; a speaker having front and back sides and a diaphragm coated with a metal layer; the electronic device disposed within the housing and coupled to the speaker; the speaker mounted in the housing with the metal layer electrically coupled to the shielding means, thereby covering the speaker opening to prevent transmission of spurious electromagnetic or radio frequency radiation through the speaker opening.
Claim 2
Dependent Claim
88 words
A shielded electronic device that is susceptible to electromagnetic radiation or that emits electromagnetic radiation, comprising: a housing having a speaker opening and a shielding means; a speaker having front and back sides and a diaphragm coated with a metal layer; the electronic device disposed within the housing and coupled to the speaker; the speaker mounted in the housing with the metal layer electrically coupled to the shielding means, thereby covering the speaker opening to prevent transmission of spurious electromagnetic or radio frequency radiation through the speaker opening.
Claim 3
Dependent Claim
23 words
The shielded electronic device of claim 1, wherein the metal layer is electrically coupled to the housing shielding means with a conductive polymer.
Claim 4
Dependent Claim
15 words
The shielded electronic device of claim 2, wherein the speaker diaphragm is a plastic film.
Claim 5
Dependent Claim
26 words
The shielded electronic device as described in claim 2, wherein the metal layer prevents the transmission of spurious electromagnetic or radio frequency radiation through the diaphragm.
Claim 6
Dependent Claim
16 words
The shielded electronic device of claim 2, wherein the metal layer is a sputtered metal coating.
Claim 7
Dependent Claim
20 words
The shielded electronic device of claim 2, wherein the diaphragm is coated with the metal layer on one side only.
Claim 8
Dependent Claim
79 words
A communication device, comprising: a housing having a speaker opening and a shielding means; a speaker having front and back sides and a diaphragm coated with a metal layer; a radio receiver disposed within the housing and coupled to the speaker; the speaker mounted in the housing with the metal layer electrically coupled to the shielding means, and the speaker covering the speaker opening to prevent the ingress or egress of spurious radio frequency radiation through the speaker opening.
Claim 9
Dependent Claim
79 words
A communication device, comprising: a housing having a speaker opening and a shielding means; a speaker having front and back sides and a diaphragm coated with a metal layer; a radio receiver disposed within the housing and coupled to the speaker; the speaker mounted in the housing with the metal layer electrically coupled to the shielding means, and the speaker covering the speaker opening to prevent the ingress or egress of spurious radio frequency radiation through the speaker opening.
Claim 10
Dependent Claim
21 words

Claim 12
Dependent Claim
15 words
The communication device of claim 7, wherein the metal coating is a sputtered metal coating.
Claim 13
Dependent Claim
19 words
The communication device of claim 7, wherein the diaphragm is coated with the metal layer on one side only.
Claim 14
Dependent Claim
23 words
The communication device of claim 7, further comprising a radio transmitter disposed within the housing, the communication device thereby comprising a two-way radio.
