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 sub-assembly, including;

a chassis having an aperture formed therein;

a compliant member coupled within the aperture for retaining the transducer; and

a substantially rigid member coupled to the transducer, the substantially rigid member providing a seal between the chassis and the housing;

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, wherein the transducer and the other transducer are assembled on different planes;

first and second grills formed in the cup-style housing; and

wherein the sub-assembly'"'"'s transducer and the other transducer comprises a speaker and a microphone, the sub-assembly being slideably insertable into the cup style housing such that the speaker and microphone align with the first and second audio grills.

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

5. The acoustical assembly of claim 4, wherein the first assembly axis and the second assembly axis are substantially perpendicular to each other.

6. The apparatus of claim 5, wherein the sub-assembly slideably inserts into the cup-style housing such that the chassis, the substantially rigid member, and the compliant member compressibly align and form a seal about the transducer.
