Abstract

An assembly (100) for acoustic sealing of a transducer (104) in a communication device is provided. The assembly (100) allows for assembly along one axis (112) and acoustical sealing along another axis (115). The assembly (100) allows for another transducer (106) to be acoustically sealed on a different plane than that of the first transducer (104). Through the use of a compliant member (204) and rigid member (108) coupled to the transducer (104) a floating seal is formed between the chassis (102) and the housing (103) of the communication device (100).

Claims

1. An apparatus providing an acoustic seal for a transducer, comprising:

a cup-style housing;

a chassis having an aperture formed therein for retaining the transducer;

a compliant member coupled to the transducer; and

a substantially rigid member providing a seal between the chassis and the housing.

2. The apparatus of claim 1, wherein the substantially rigid member is formed having a chamfered surface.

3. The apparatus of claim 1, further comprising adhesive disposed on the substantially rigid member.

4. The apparatus of claim 1, further comprising another transducer and a flexible circuit board, wherein the flexible circuit board mechanically couples the transducer and the other transducer, and wherein the other transducer forms an independent acoustic seal with the housing by using another compliant member and another substantially rigid member.

5. The apparatus, of claim 4, wherein the transducer and the other transducer are assembled on different planes.

6. An acoustical assembly for a communication device, comprising:

a cup-style housing;

a sub-assembly, comprising;

a chassis having an aperture formed therein,

a transducer retained within the aperture;

a substantially rigid member operatively coupled to the transducer;

at least one compliant member operatively coupled to the transducer; and

the sub-assembly insertable into the housing through a first assembly axis, the substantially rigid member forming a seal between the housing and chassis through a second assembly axis.

7. The acoustical assembly of claim 6, wherein the first and second assembly axis are substantially perpendicular to each other.

8. An assembly for acoustical porting of a transducer, comprising:

a housing having an opening;

a sub-assembly comprising;

a chassis having an aperture formed therein,

a transducer retained within the aperture;

a substantially rigid member operatively coupled to the transducer;

at least one compliant member operatively coupled to the transducer; and

wherein the sub-assembly slidably inserts into the opening of the housing such that the chassis, the substantially rigid member, and the at least one compliant member compressibly align and seal about the transducer.

9. An assembly for acoustical porting of a transducer, comprising:

a housing having first and second audio grills and an opening;

a sub-assembly comprising;

a chassis having a first and second apertures formed therein,

first and second transducers retained within the first and second apertures respectively;

first and second substantially rigid members operatively coupled to the first and second transducers respectively;

a first compliant member coupled between the first substantially rigid member and the first transducer;

a second compliant member coupled between the second substantially rigid member and the second transducer; and

wherein the sub-assembly slidably inserts into the opening of the housing such that the first and second substantially rigid members align and seal about the first and second grills respectively, and the first and second compliant members compressibly seal about the first and second transducers.

10. The assembly of claim 9, wherein the first and second compliant members enable each of the first and second transducers to float independently of each other.

11. A radio, comprising:

a cup-style housing;

a sub-assembly comprising;

a chassis having first and second apertures formed therein;

a speaker;

a first compliant member coupled to the speaker;

a first substantially rigid member coupled to the first compliant member;

a first support ledge formed about the first aperture for supporting the speaker;

a microphone aligned within the second aperture;

a second compliant member coupled within the second aperture;

a second substantially rigid member coupled to the second compliant member;

a flex mechanically coupling the speaker and microphone;

a printed circuit board (pcb) having electronic circuitry;

an electrical interconnect coupled to the pcb;

a second support ledge protruding from the chassis for supporting the flex, the flex making electrical contact with the electrical interconnect of the pcb; and

wherein the first compliant member and first substantially rigid member provide a seal between the chassis and the housing, and the second compliant member and second substantially rigid member form a second seal between the chassis and the housing thereby allowing the speaker and microphone to compress against the housing independently of each other.

12. The radio of claim 11, wherein the speaker and microphone are assembled on different planes.

13. The radio of claim 11, further comprising a third compliant member coupled between the speaker and the chassis about the first aperture.
