Environmental sensors may include one or more environmental sensor components and one or more acoustic components. Acoustic components may include a speaker or a microphone. Environmental sensor components may include a temperature sensor, a pressure sensor, a humidity sensor, a gas sensor, or other sensors or combinations of sensors for sensing attributes of the environment surrounding the device. The environmental sensor may have an enclosure with an opening. The enclosure may be formed from a rigid support structure and a portion of a printed circuit. The opening may be formed in the rigid support structure or the printed circuit. The opening in the enclosure for the environmental sensor may be aligned with an opening in an outer structural member for the device. The outer structural member may be a housing structure or a cover layer for a device display. ## Claims ### Claim 1 An electronic device comprising: a housing having a first opening; a printed circuit; a rigid support structure attached to the printed circuit; an acoustic component attached to the printed circuit; and a sensor attached to the printed circuit, wherein the rigid support structure and a portion of the printed circuit form an enclosure that surrounds the sensor and the acoustic component, wherein the enclosure comprises a second opening, and wherein air passes through the first and second openings into the enclosure. ### Claim 2 (depends on 1) The electronic device defined in claim 1, wherein the sensor comprises a sensor selected from the group consisting of: a gas sensor, a smoke detector, a pressure sensor, a temperature sensor, and a humidity sensor. ### Claim 3 (depends on 2) The electronic device defined in claim 2, wherein the acoustic component comprises a microphone. ### Claim 4 (depends on 1) The electronic device defined in claim 1, wherein the sensor comprises a gas sensor that is configured to measure a concentration of a gas. ### Claim 5 (depends on 4) The electronic device defined in claim 4, wherein the gas comprises a gas selected from the group consisting of: carbon monoxide, carbon dioxide, alcohol vapor, propane, ozone, nitric oxide, nitrogen dioxide, benzene, methane, hydrogen, and oxygen. ### Claim 6 (depends on 1) The electronic device defined in claim 1, wherein the second opening comprises an opening in the rigid support structure. ### Claim 7 (depends on 6) The electronic device defined in claim 6, wherein the second opening is aligned with the first opening. ### Claim 8 (depends on 1) The electronic device defined in claim 1, wherein the second opening comprises an opening in the printed circuit. ### Claim 9 (depends on 8) The electronic device defined in claim 8, wherein the second opening is aligned with the first opening. ### Claim 10 (depends on 1) The electronic device defined in claim 1, wherein the acoustic component comprises a permeable membrane, wherein the second opening is aligned with the permeable membrane, and wherein air passes through the second opening and the permeable membrane into the enclosure. ### Claim 11 (depends on 1) The electronic device defined in claim 1, wherein the acoustic component and the sensor are formed from a common semiconductor die. ### Claim 12 (depends on 1) The electronic device defined in claim 1, further comprising: mesh that covers that first opening. ### Claim 13 An electronic device comprising: a housing having a first opening; and an environmental sensor having an enclosure with a second opening, wherein the environmental sensor includes an acoustic component with a permeable membrane and a sensor, and wherein air passes through the first opening, the second opening, and the permeable membrane into the enclosure. ### Claim 14 (depends on 13) The electronic device defined in claim 13, further comprising: mesh that covers the first opening. ### Claim 15 (depends on 13) The electronic device defined in claim 13, wherein the acoustic component comprises a microphone. ### Claim 16 (depends on 15) The electronic device defined in claim 15, wherein the sensor comprises a sensor selected from the group consisting of: a gas sensor, a smoke detector, a pressure sensor, a temperature sensor, and a humidity sensor. ### Claim 17 (depends on 13) The electronic device defined in claim 13, wherein the enclosure is formed by a printed circuit and a rigid support structure attached to the printed circuit. ### Claim 18 An electronic device comprising: a housing having a first opening; mesh that covers the first opening; a printed circuit; a rigid support structure attached to the printed circuit; an acoustic component attached to the printed circuit; and a gas sensor attached to the printed circuit that is configured to measure a concentration of a gas, wherein the gas comprises a gas selected from the group consisting of: carbon monoxide, carbon dioxide, alcohol vapor, propane, ozone, nitric oxide, nitrogen dioxide, benzene, methane, hydrogen, and oxygen, wherein the rigid support structure and a portion of the printed circuit form an enclosure that surrounds the gas sensor and the acoustic component, and wherein the enclosure comprises a second opening. ### Claim 19 (depends on 18) The electronic device defined in claim 18, wherein the acoustic component comprises a microphone. ### Claim 20 (depends on 18) The electronic device defined in claim 18, wherein the acoustic component comprises a speaker.
