## Background
BACKGROUND
Although many people are accustomed to modern “smart phones” that they carry around in their pocket, the small form factor is less ideal for prolonged use. When portability is not a priority, such as in a desk environment, people prefer larger telephones that provide better ergonomics, desk stability, and ready availability. However, these large telephones can seem outdated in comparison to their thinner and lighter consumer counterparts.

DESCRIPTION
As shown in FIG. 1A, telephone 100 can be a modern and attractive desk or wall-mounted telephone. In some embodiments, telephone 100 has handset 102 and display panel 106. Phone 100 can have physical buttons such as volume rocker 106 and mute button 108. Phone 100 can contain unibody plate 104 for aesthetic design and structural support. In some embodiments, telephone 100 can be placed on a desk in various positions provided by stand 112. In some embodiments, stand 112 can fold with the remainder of telephone 100 allowing telephone 100 to be mounted on a wall.
FIG. 1B depicts an exploded view of some components of telephone 100. For example, display panel 106 can be placed on the front portion of unibody plate 104 while speaker mount 120, speaker cradle 122, and electronics board 126 can be placed on the back portion (e.g., rear) of unibody plate 104. Backplate 128 can be placed behind unibody plate 104 and can cover internal components such as electronics board 126 while also providing some structural support. Volume rocker 106 and mute button 108 can be placed in front of unibody plate 104 and within openings in display panel 106. It should be understood that FIGS. 1A and 1B are not complete representations of the components that can comprise telephone 100. In some embodiments, telephone 100 has more or fewer components. For example, in some embodiments, telephone 100 can omit handset 102 and in some embodiments, telephone 100 can have an antenna for wireless communication.
Display panel 106 can be a touchscreen display panel. In some such embodiments, display panel 106 can present various interfaces such as a 10-key dialer, a directory, status indicators, etc. In some embodiments, display panel 106 can facilitate video telephony. Display panel 106 can be combined with haptic feedback to enhance touchscreen usability and provide intuitive interaction. Display panel 106 can comprise a hard transparent panel such as glass. Display panel 106 can have an opaque bezel surrounding a display element such as a liquid crystal display. Within the bezel region, there can be translucent or transparent regions through which indicator lights can be seen. In some embodiments, the bezel can have one or more apertures cut out, through which buttons (e.g., mute button 108) can pass through. In some embodiments, there is a translucent or transparent region surrounding an aperture where an indicator light can be seen. For example, if the aperture is a circle and mute button 108 passes through the circle, there can be a translucent ring around the aperture that, when illuminated, can indicate that telephone 100 is muted. In some embodiments, display panel 106 can contain processing and battery power so that it can be removed and operate independently from telephone 100, for example as a tablet computer or mobile telephone. In some embodiments, display panel 106 is attached to telephone 100 along with a cushion element such as rubber to absorb small vibrations that might result from user operation and to provide a seamless fit between display panel 106 and the rest of telephone 100.
FIG. 2A depicts an example unibody plate 104 in isolation from other components. In some embodiments, unibody plate 104 is a single piece of material. Unibody plate 104 can be made out of aluminum, magnesium, plastic, wood, carbon fiber, etc. and can be machined, die-cast, forged, carved, 3D printed, grown, molded, etc. Unibody plate 104 can be created using a combination of materials and techniques. Unibody plate 104 can be made of denser materials that, because of the increased weight, signal to the user that telephone 100 is a premium product of sturdy construction. Unibody plate 104 can have exposed portions such as speaker vent 202 as well as hidden portions (i.e., hidden when telephone 100 is assembled) such as display cradle 208. Unibody plate 104 can contain openings such as pass-through 206, USB aperture 230, and headset aperture 232 whereby components such as cables can pass through or be accessed through unibody plate 104. In some embodiments, such openings are in places not required for structural support. In some embodiments, openings can be created to optimize weight, encourage heat dissipation, and minimize material cost. In some embodiments, such an optimal weight is a weight that minimizes slippage of telephone 100 while resting on a desk during normal use. Because telephone 100 utilizes unibody plate 104, telephone 100 can be thinner as the unibody plate provides strength and rigidity to the assembled device. The materials chosen for the unibody plate must be able to provide the requisite strength and rigidity to support all of the phone components, and especially the display panel. Components can be glued or fastened to unibody plate 104.
Unibody plate 104 can have a front portion and a back portion. In FIG. 2A, the front portion is the visible portion while the back portion is the opposite side (shown in FIG. 2C). In some embodiments, back plate 128 is mounted to the back portion of unibody plate 104. In some embodiments, the perimeter of unibody plate has a ridge designed to receive clips on back plate 128.
Front panel 104 can snap in, rest upon, or otherwise be supported by unibody plate 104. In some embodiments, display cradle 208 can be a recessed portion of unibody plate 104 wherein display panel 106, when installed, lies flush with an exposed surface of unibody plate 104.
Speaker vent 202 can be a grating, mesh, collection of apertures, etc. to mitigate the passage of dust and debris while allowing sound to pass through.
FIG. 2B shows a side view of unibody plate 104. Thickness 250 can be the maximum width of unibody plate 104 (excluding mount 240a and mount 240b which can be located towards the center of unibody plate 104). In some embodiments, thickness 250 also represents the perimeter thickness of telephone 100 (excluding a fillet) while telephone 100 can have a greater thickness towards the center of telephone 100. Therefore, an exposed perimeter of unibody plate 104 can appear to substantially define the overall thickness of telephone 100, with the thicker elements being relatively hidden. Thickness 250 can be greater than 4.5 millimeters (“mm”) to accommodate USB aperture 230 and less than 20 mm. Other effective ranges of thickness 250 can include 5 mm-9 mm and 7.5 mm-8.5 mm.
FIG. 3A shows speaker assembly 300. Speaker assembly 300 can be integral to unibody plate 104 or be made of separate components. Speaker assembly 300 can house a speaker (not depicted) that can be used for “speakerphone” capabilities of telephone 100. In some embodiments, speaker assembly 300 is set behind speaker vent 202 formed in the unibody plate. As depicted in FIG. 1B, speaker assembly can comprise speaker mount 120 and speaker cradle 122. In some embodiments, speaker mount 120 and speaker cradle 122 are one integrated unit. In some embodiments, speaker mount 120 can have ridge 302 as a feature. Ridge 302 can provide an acoustic seal by interfacing with the unibody plate to provide enhanced sound quality from speaker assembly 300 and prevent rattling between speaker assembly 300 and unibody plate 104. In some embodiments, ridge 302 is rubber, silicone, glue, adhesive, wood, plastic, etc. In some embodiments, ridge 302 is a feature that is contiguous with speaker mount 300. In some embodiments, speaker cradle 122 does not hold a speaker but is a speaker (i.e., a transducer).
FIG. 3B shows an exploded view of speaker assembly 300 including speaker mount 120 and speaker cradle 120. Speaker cradle 120 can have an interior portion 306 formed inside of speaker cradle 120 and mounting holes 304 for mounting speaker cradle 120 to back plate 128.
FIG. 4 depicts an exploded view of mute button 108. As mentioned previously, in some embodiments, mute button 108 is positioned alongside a touchscreen and within an aperture in display panel 106. In some embodiments, other buttons (e.g., volume rocker 106) can be made using the principles disclosed for mute button 108 but for other tasks such as “pick up”, “hang up”, “speakerphone”, “volume”, etc. Mute button 108 can provide a tactile response to help a user recognize that mute button 108 has been pressed. In some embodiments, mute button 108 or a region near or surrounding mute button 108 can be illuminated to indicate mute button's 108 status, for example, when telephone 100 is muted.
Cap 402 can be affixed to translucent dome 406a which can rest on or be integral to translucent dome 406b which can be held by button holder 408. Translucent dome 406a and translucent dome 406b can collectively be referred to as translucent dome 406. Mute button 108 can comprise illumination element 410 that can provide a status indicator for mute button 108. Cap 402 can be opaque, translucent, or a combination of the two. For example, cap 402 can be generally opaque except for a translucent icon or design on top. Cap 402 can have a contact portion where a user can push to activate mute button 108. Cap 402 can be fixed to translucent dome 406 using adhesive, friction, etc. In some embodiments, cap 402 is a material that is painted on or combined with translucent dome 406.
Translucent dome 406 can comprise two components that are jointly molded using a double shot injection mold. In some embodiments, translucent dome 406a can be a stiff material while translucent dome 406b can be a more flexible material such as silicone. In some embodiments, translucent dome 406a has central portion 412 for receiving cap 402 and outer portion 414. Outer portion 414 can diffuse light coming from illumination element 410 so that it appears uniform from above. For example translucent dome 406 can be located directly under display panel 106. This can permit a ring of uniform light to be seen through display panel 106 in a region surrounding the cap which resides within an opening in display panel 106. Tab 416 can protrude horizontally from translucent dome 406a and activate a switch in telephone 100 that detects that mute button 108 has been depressed.
Button seat 408 can be attached to a PCB and can hold translucent dome 406 in place to prevent slipping. Button seat 408 can have a raised lip for this effect.
FIG. 5A shows the inside of back plate 128 in isolation. Back plate 128, when combined with other components of telephone 100, can form one or more cavities. For example, speaker cavity 504 to house speaker assembly 300 and electronics cavity 502. Electronics cavity 502 can be a central location within back plate that provides space for more bulky components of telephone 100 to be hidden. For example, electronics cavity can accommodate at least one telecommunications port (e.g., an RJ45 port, RJ11 port, etc.) as well as a power receptacle. Back plate 128 can be attached to a back portion of unibody plate 104. In some embodiments, back plate 128 has tabs 416 for connecting to unibody plate 104. This can make it so that back plate 128 does not require screws to mount it onto unibody plate 104 and thus back plate 128 can have no visible screws or screw holes (though internal, hidden, screws and holes may be used).
FIG. 5B shows a side view of back plate 128. As discussed above, electronics cavity 502 can be located centrally within back plate 128 to keep thickness 250 around the perimeter of telephone 100 to a minimum and creating the impression that thickness 250 is the defining width of telephone 100. The shape of back portion of back plate 128 can be triangular, curved, trapezoidal etc. Thickness 504 can represent the width of back plate 128 at electronics cavity 502 (e.g., defining the “thickest dimension” of the “thickest portion”). Thickness 504 can be 15 mm-50 mm, including ranges of 20 mm-25 mm, and 22 mm-23 mm. Thickness 504 can be 22.5 mm. Various thicknesses 504 can be appropriate based on the size and type of components in electronics cavity 502. Backplate can have openings through which cables and pass.
