Abstract
Low-profile electronic component apparatus and methods of manufacturing and utilizing the same, for use with low-profile mobile devices and other applications. In one embodiment, the mobile device comprises a wireless-enabled smartphone, tablet, or laptop computer, and the component comprises an audio speaker which is recessed into a metallic support element, the latter recessed into the mobile device outer housing. The support element is coated with an insulating material, and conductive traces formed thereon for electrical interface with the contacts of the speaker. When assembled, the installation results in a substantially reduced overall vertical profile, thereby both potentially reducing the overall required thickness of the host device, and creating additional volume within the device housing (such as for other components, and/or enhanced audio response of the speaker) resulting in an additional spacing between the speaker component and any extant antenna assemblies.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
(11) Reference is now made to the drawings wherein like numerals refer to like parts throughout. As used herein, the terms “board” and “substrate” refer generally and without limitation to any substantially planar, stepped, or curved surface or component upon which other components can be disposed. For example, a substrate may comprise a single or multi-layered printed circuit board (e.g., FR4), a semi-conductive die or wafer, or even a surface of a housing or other device component, and may be substantially rigid or alternatively at least somewhat flexible.
(12) As used herein, the terms “portable device”, “mobile computing device”, “client device”, “portable computing device”, and “end user device” include, but are not limited to, personal computers (PCs) and minicomputers, whether desktop, laptop, or otherwise, set-top boxes, personal digital assistants (PDAs), handheld computers, personal communicators, tablet computers, portable navigation aids, J2ME equipped devices, cellular telephones, smartphones, personal integrated communication or entertainment devices, or literally any other device capable of interchanging data with a network or another device.
(13) As used herein, the terms “speaker”, “speaker component” and “speaker element” refer without limitation to any device capable of emitting acoustic energy within one or more desired frequency ranges. Speakers may include, purely as examples, cone-and-coil type devices, piezoelectric transducers, phased array audio systems, passive radiators, sub-acoustic transducers (e.g., sub-woofers), plasma arc devices, electrostatic speakers, etc.
(14) As used herein, the terms “top”, “bottom”, “side”, “up”, “down”, “left”, “right”, and the like merely connote a relative position or geometry of one component to another, and in no way connote an absolute frame of reference or any required orientation. For example, a “top” portion of a component may actually reside below a “bottom” portion when the component is mounted to another device (e.g., to the underside of a PCB).
(15) As used herein, the term “wireless” means any wireless signal, data, communication, or other interface including without limitation Wi-Fi, Bluetooth, 3G (e.g., 3GPP, 3GPP2, and UMTS), HSDPA/HSUPA, TDMA, CDMA (e.g., IS-95A, WCDMA, etc.), FHSS, DSSS, GSM, PAN/802.15, WiMAX (802.16), 802.20, narrowband/FDMA, OFDM, PCS/DCS, Long Term Evolution (LTE) or LTE-Advanced (LTE-A), analog cellular, CDPD, satellite systems such as GPS, millimeter wave or microwave systems, optical, acoustic, and infrared (i.e., IrDA).
(16) Overview
(17) The present disclosure provides, in one salient aspect, methods and apparatus for reducing the profile of electronic components (such as e.g., audio speakers) installed in electronic devices, such as e.g., within “thin” devices such as smartphones, tablets, and laptop computers. Concurrently, reductions in interior volume consumed by such components within the host device, and interference between such components and antennae of the host device, may be realized as well.
(18) Advantageously, the various aspects of the present disclosure can be applied to any number of types of mobile or non-mobile devices, and also may obviate use of more costly and/or complicated processes such as laser direct structuring (LDS).
(19) In one implementation, the methods and apparatus include replacement of a portion of the host device housing in the desired installation location with an insert or support element of significantly lower width than the surrounding housing. In this fashion, the component(s) (e.g., speaker) are recessed into the housing volume, thereby reducing their vertical profile within the interior volume of the host device.
(20) In one variant, a direct deposition process is used to deposit conductive traces on the insert or support element in order to facilitate electrical connection and reduce manufacturing cost.
Detailed Description of Exemplary Embodiments

(37) Next, per step 604, the (two dimensional) material shape is formed into the three-dimensional shape shown in
(38) Next, per step 606, the formed support element 202 is then coated wholly or partly with an electrically insulating material. For example, in one embodiment the coating can be applied using any number of techniques including vapor deposition, spraying (e.g., via atomization gun), dip-coating, etc. In one implementation, the coating is deposited so as to provide adequate electrical insulation yet not unnecessarily increase the thickness of the support element 202 as a whole. Alternatively, the support element may be oxidized using well understood techniques in order to provide the requisite level of insulation. It is also appreciated that the aforementioned coating can be applied prior to any of the steps of the method 600, e.g., at time of manufacture of the sheet/roll stock, or before deformation but after cutting.
(39) Next, per step 608, the conductive traces are disposed onto the relevant support element surfaces. In one variant, a conductive ink or fluid deposition technique is applied, using for example the methods and apparatus disclosed in co-owned U.S. patent application Ser. No. 14/736,040 filed Jun. 10, 2015 entitled “METHODS AND APPARATUS FOR CONDUCTIVE ELEMENT DEPOSITION AND FORMATION”, which claims priority to U.S. Provisional Patent Application Ser. No. 62/018,410 filed Jun. 27, 2014 entitled “METHODS AND APPARATUS FOR CONDUCTIVE ELEMENT DEPOSITION AND FORMATION”, as well as U.S. Provisional Patent Application Ser. No. 62/026,560 filed Jul. 18, 2014 entitled “METHODS AND APPARATUS FOR CONDUCTIVE ELEMENT DEPOSITION AND FORMATION”, and/or co-owned and co-pending U.S. patent application Ser. No. 13/782,993 entitled “DEPOSITION ANTENNA APPARATUS AND METHODS” filed Mar. 1, 2013, which claims priority to U.S. Provisional Patent Application Ser. No. 61/606,320 of the same title filed Mar. 2, 2012, U.S. Provisional Patent Application Ser. No. 61/609,868 of the same title filed Mar. 12, 2012, and U.S. Provisional Patent Application Ser. No. 61/750,207 of the same title filed Jan. 8, 2013, and/or U.S. patent application Ser. No. 14/620,108 filed Feb. 11, 2015 and entitled “METHODS AND APPARATUS FOR CONDUCTIVE ELEMENT DEPOSITION AND FORMATION”, which claims priority to U.S. Provisional Patent Application Ser. No. 61/939,197 entitled “DEPOSITION ANTENNA APPARATUS AND METHODS” filed Feb. 12, 2014, each of the foregoing incorporated herein by reference supra. Using such techniques, the traces can be readily applied to various three-dimensional geometries, and easily cured thereafter, thereby providing a rapid and cost-efficient approach to conductive trace formation. Other techniques may be used as well, such as for example use of templates or masks combined with large area spray deposition, silk screening techniques, etc. As above, the conductive trace deposition and/or curing process (if required) can be performed at various points within the manufacturing method 500, such as at time of material stock fabrication, after cutting but before forming, etc. The conductive traces can also be formed in two or more parts, such as where one portion is deposited prior to material deformation, and another deposited after the deformation, so as to ensure that the trace electrical and mechanical properties are not compromised during bending or deformation of the underlying material.
(40) Next, at step 610, the support element 202 is insert molded using a polymer material in order to form the polymer housing. While the use of insert-molding is exemplary, it is readily appreciated that other known techniques may be utilized such as transfer molding techniques, etc.
(41) Finally, at step 612, the speaker component 302 is placed within the support element 202 and the conductive leads present on the speaker component are attached to the conductive traces 207 thereby finishing the manufacturing process.
(42)
(43) Next, per step 704, the (two dimensional) material shape is formed into the three-dimensional shape shown in
(44) Next, per step 706, the formed support element 252 is then coated wholly or partly with an electrically insulating material. For example, in one embodiment the coating can be applied using any number of techniques including vapor deposition, spraying (e.g., via atomization gun), dip-coating, etc. In one implementation, the coating is deposited so as to provide adequate electrical insulation yet not unnecessarily increase the thickness of the support element 252 as a whole. Alternatively, the support element may be oxidized using well understood techniques in order to provide the requisite level of insulation. It is also appreciated that the aforementioned coating can be applied prior to any of the steps of the method 700, e.g., at time of manufacture of the sheet/roll stock, or before deformation but after cutting.
(45) Next, at step 710, the support element 252 is insert molded using a polymer material in order to form the polymer housing. While the use of insert-molding is exemplary, it is readily appreciated that other known techniques may be utilized such as transfer molding techniques, etc. Moreover, the support element 252 and the housing element 304 may be separately formed with the support element 252 subsequently post-inserted into the housing element (i.e., after the housing element 304 has been formed)
(46) Next, per step 710, the conductive traces are disposed onto the relevant support element surfaces. In one variant, a conductive ink or fluid deposition technique is applied, using for example the methods and apparatus disclosed in co-owned U.S. patent application Ser. No. 14/736,040 filed Jun. 10, 2015 entitled “METHODS AND APPARATUS FOR CONDUCTIVE ELEMENT DEPOSITION AND FORMATION”, which claims priority to U.S. Provisional Patent Application Ser. No. 62/018,410 filed Jun. 27, 2014 entitled “METHODS AND APPARATUS FOR CONDUCTIVE ELEMENT DEPOSITION AND FORMATION”, as well as U.S. Provisional Patent Application Ser. No. 62/026,560 filed Jul. 18, 2014 entitled “METHODS AND APPARATUS FOR CONDUCTIVE ELEMENT DEPOSITION AND FORMATION”, and/or co-owned and co-pending U.S. patent application Ser. No. 13/782,993 entitled “DEPOSITION ANTENNA APPARATUS AND METHODS” filed Mar. 1, 2013, which claims priority to U.S. Provisional Patent Application Ser. No. 61/606,320 of the same title filed Mar. 2, 2012, U.S. Provisional Patent Application Ser. No. 61/609,868 of the same title filed Mar. 12, 2012, and U.S. Provisional Patent Application Ser. No. 61/750,207 of the same title filed Jan. 8, 2013, and/or U.S. patent application Ser. No. 14/620,108 filed Feb. 11, 2015 and entitled “METHODS AND APPARATUS FOR CONDUCTIVE ELEMENT DEPOSITION AND FORMATION”, which claims priority to U.S. Provisional Patent Application Ser. No. 61/939,197 entitled “DEPOSITION ANTENNA APPARATUS AND METHODS” filed Feb. 12, 2014, each of the foregoing incorporated herein by reference supra.

(48) It will be recognized that while certain aspects of the disclosure are described in terms of a specific sequence of steps of a method, these descriptions are only illustrative of the broader methods of the disclosure, and may be modified as required by the particular application. Certain steps may be rendered unnecessary or optional under certain circumstances. Additionally, certain steps or functionality may be added to the disclosed embodiments, or the order of performance of two or more steps permuted. All such variations are considered to be encompassed within the disclosure disclosed and claimed herein.
(49) While the above detailed description has shown, described, and pointed out novel features of the disclosure as applied to various embodiments, it will be understood that various omissions, substitutions, and changes in the form and details of the device or process illustrated may be made by those skilled in the art without departing from the disclosure. The foregoing description is of the best mode presently contemplated of carrying out the disclosure. This description is in no way meant to be limiting, but rather should be taken as illustrative of the general principles of the disclosure.
