Referring to FIG. 1, an exemplary communication device 100 is shown, in accordance with an embodiment of the present invention. The communication device 100 can be, for example, a wireless clam-shell telephone. In FIG. 1, a housing 101 of the communication device 100 can include two portions—a flip portion 102 and a base portion 104. It should be appreciated that various embodiments of the present invention can also be practiced in a communication device that comprises only one housing portion. The flip portion 102 can house a display 106, an earpiece port 108, a transducer, and a seal (not shown in FIG. 1). The base portion 104 can include a keypad 110 for entering numbers and text, etc., and an audio receiver 112 for receiving input audio signals from users.
Referring to FIG. 2, an image of an underneath side of a seal 200 is shown, in accordance with a first embodiment of the inventive arrangements. The seal 200 may be an integrated structure that protects and insulates the components of the communication device 100 while providing extra space inside the flip portion 102. It is understood, however, that the seal 200 can be constructed of two or more pieces that are joined together through any suitable means. The extra space can be used, for example, to increase the display size while providing a good audio quality to a user of the communication device 100.
The seal 200 can be made of any suitable material that provides the required insulation and support and allows audio signals to be routed without undue attenuation. As an example, the seal 200 can be constructed of a compliant material, such as silicon rubber, although other suitable substances can be used, even rigid materials. The term compliant material can mean any material that can be molded or formed into a three-dimensional shape. The seal 200 can include a transducer portion 202, a display portion 204, and an audio tunnel 206. The transducer portion 202 can insulate a transducer (not shown here) in the communication device 100. The shape of the transducer portion 202 can be circular, rectangular or any other shape that complements the shape of the transducer. The transducer portion 202 can include an audio port 208 that can help direct audio signals to the outside of the communication device 100, including those signals that enter the audio tunnel 206.
The display portion 204 can protect the display 106 in the communication device 100. An exemplary display for communication devices is a liquid crystal display (LCD). The shape of the display portion 204 may complement the shape of the display 106 and can protect the display 106 from dust, liquids, and other such contaminants or from the shock produced when the device 100 is accidentally dropped or bumped. As will be described below, the audio tunnel 206 can provide a passage for audio signals to propagate underneath parts of the display 106 and to disperse out of the communication device 100.
Referring to FIG. 3, an image of a top side of the seal 200 is shown, in accordance with the first embodiment of the inventive arrangements. The transducer portion 202, the display portion 204, and the audio port 208 are shown in FIG. 3. As will be shown later, it is on the top side of the seal 200 where a transducer and the display 106 can be positioned.
Referring to FIG. 4, a cross-sectional image of the flip portion 102 of the communication device 100 is shown, in accordance with an embodiment of the present invention. The flip portion 102 can include the seal 200, the display 106, the earpiece port 108 and a transducer 402. The audio signals generated by the transducer 402 can be dispersed out through the earpiece port 108. As explained earlier, the seal 200 can include the transducer portion 202, the display portion 204, and the audio tunnel 206. The transducer portion 202 of the seal 200 can include the audio port 208, which can be communicatively coupled with the audio tunnel 202 to provide a passage for the audio signal to disperse out the communication device 100 through the earpiece port 108. A potential path taken by the audio signals generated by the transducer 402 is represented by several arrows.
In one embodiment, the flip portion 102 may include an audio seal 410, which can include an aperture 412. This audio seal 410 is an optional feature, although the aperture 412 can help direct sound from the transducer to the earpiece port 108. In another embodiment, the earpiece port 108 can include a grill (not shown) or a mesh (not shown) to help prevent dirt or other contaminants from entering the flip portion 102 through the earpiece port 108.
In accordance with an embodiment of the invention, the audio tunnel 206 can be positioned beneath the display 106. In particular, the audio tunnel 206 can be positioned beneath a non-active part 404 of the display 106. A non-active part of the display can be defined as a part of the display 106 that does not display actual images. As can be seen, the transducer portion 202 can protect the non-active part 404 of the display 106. The display 106 can also include an active part 406, which can be defined as that part of a display that actually displays images. In one arrangement, the display portion 204 of the seal 200 can protect at least a portion of the active part 406 of the display 106.
In view of the audio tunnel 206, the earpiece port 108 can be positioned farther away from the top of the flip portion 102. This configuration, however, does not require the display 106 to be moved farther away from the top of the flip portion 102, as a portion of the display 106 can be positioned over the audio tunnel 206. In addition, prior art systems include displays in which the non-active portion of the display is positioned at the end of the display that is opposite that of the top of the flip portion. In contrast, because the non-active part 404 of the display 106 is positioned near the top of the flip portion 102, the inventive system can allow for more room at the opposite end of the display 106.
Referring to FIG. 5, another cross-sectional diagram of the flip portion 102 of the communication device 100 is shown, in accordance with another embodiment of the present invention. The seal 200 is positioned inside the flip portion 102. The audio port 208 and the audio tunnel 206 can route audio signals from the transducer 402 to disperse out of the communication device 100. The audio tunnel 206 can route the audio signals underneath the non-active part 404 of the display 106. The audio signals may be dispersed out from the communication device 100 through the earpiece port 108.
In accordance with an embodiment of the present invention, the distance, ‘l’, from the tip of the flip portion 102 to the bottom of the earpiece port 108, can be varied depending on the overall design of the flip portion 102. Accordingly, in one arrangement, the length of the audio tunnel 206 can be kept such that audio signals can propagate underneath the display 106. For example, the distance from the tip of the flip portion 102 to the bottom of the earpiece port 108 can be kept as 0.013 meters (13 millimeters). This position of the earpiece port 108 has been experimentally determined to provide best audio quality to the users. It is understood, however, that the distance from the top of the flip portion 102 to the bottom of the earpiece port 102 can be any other suitable distance.
Referring to FIG. 6, a flowchart for a method for assembling a communication device is shown, in accordance with an embodiment of the present invention. In accordance with an embodiment of the present invention, the communication device can be a wireless clam-shell device. The communication device can include a housing portion, which can have a seal, a display, a transducer and an earpiece port. At step 602, the transducer can be positioned on a transducer portion of the seal. The seal can further include an audio port and an audio tunnel.
At step 604, the display can be placed on a display portion of the seal such that the display portion, for example, can be placed behind the audio tunnel. The display can have an active part and a non-active part. In accordance with an embodiment of the present invention, the non-active part of the display can be positioned behind the audio tunnel. At step 606, the transducer, the display, and the seal can be positioned inside a flip portion of the communication device such that the seal can form the audio tunnel, which, coupled with the audio port, can provide an underneath passage for audio signals to disperse out of the communication device through the earpiece port.
At step 608, the earpiece port can be positioned such that the bottom of the earpiece port lies at a distance of, for example, approximately 13 mm from the tip of the flip portion of the communication device. At step 610, the audio tunnel can be positioned such that an end of the audio tunnel can be extended to a bottom of the earpiece port. It must be noted that the method is not limited to the order of the steps listed here, and the method may include a greater or fewer number of the steps presented here.
Various embodiments of the present invention provide a seal in a communication device. The seal can protect and insulate a display and a transducer in the communication device. The seal can make provisions for extra space inside the communication device. The extra space can be utilized for some other purposes, such as providing a bigger display, while ensuring a good audio quality to users of the communication device.
While the preferred embodiments of the invention have been illustrated and described, it will be clear that the invention is not so limited. Numerous modifications, changes, variations, substitutions and equivalents will occur to those skilled in the art without departing from the spirit and scope of the present invention as defined by the appended claims.
