Technical Field

[0013] The specific embodiments shown below are intended to be descriptions of various configurations of the subject technology and are not intended to represent the only configuration that the subject technology can be put into practice. The accompanying drawings are incorporated herein and constitute a part of the detailed description. The detailed description includes specific details intended to provide a thorough understanding of the subject technology. However, it will be clear and obvious to those skilled in the art that the subject technology is not limited to the specific details shown herein and can be put into practice without these specific details. In some cases, well-known structures and components are shown in block diagram form to avoid blurring the concept of the subject technology.

[0014] Portable electronic devices (such as mobile phones, portable music players, tablet computers, laptop computers), wearable devices (such as smart watches, headphones, earbuds, other wearable devices), etc. typically include one or more audio transducers, such as one or more microphones for receiving sound input and / or one or more speakers for generating sound. However, challenges may arise when implementing audio transducers (such as speakers) into compact electronic devices, where space for the audio transducer and other components of the electronic device (such as a display) may be limited.

[0015] According to various aspects of the subject disclosure, an audio transducer system (such as a speaker system) for an electronic device mitigates electromagnetic interference to a display of the electronic device. For example, the speaker system may include a first speaker and a second speaker, both of which are installed adjacent to a data line of the display (e.g., a conductive element configured to carry a data signal to a display pixel of the display). The first speaker and the second speaker may operate acoustically and mechanically in phase while being electrically out of phase (e.g., one hundred and eighty degrees out of phase). In one or more specific implementations, this may be achieved by providing a speaker magnet (e.g., a permanent magnet) with reversed magnetic polarity to the first speaker and the second speaker. A speaker control current may then be provided in opposite directions through the voice coils of the first speaker and the second speaker to operate the first speaker and the second speaker to generate sound. In one or more other specific implementations, the winding of the voice coil of the first speaker may be wound in a direction opposite to the direction of the winding of the voice coil of the second speaker, rather than providing different currents.

[0016] exist Figure 1 An exemplary electronic device is shown in FIG. Figure 1In the example of FIG. 1 , electronic device 100 includes a display such as display 110 mounted on a front face of housing 106. Electronic device 100 may include one or more input / output devices (such as a touch screen incorporated into display 110), buttons, switches, dials, crowns, keyboards, and / or other input and / or output components disposed on or behind display 110 or disposed on, behind, or within other portions of housing 106. Display 110 and / or housing 106 may include one or more openings to accommodate buttons, speakers, light sources, or cameras (as examples).

[0017] exist Figure 1 In the example of , the electronic device 100 includes a plurality of speakers 114 disposed within the housing 106 (e.g., disposed behind the display 110). For example, the speakers 114 can be oriented to project sound through the display 110, through one or more openings in the display 110, and / or through one or more openings in the housing 106.

[0018] exist Figure 1 In the example of , the display 110 includes a plurality of data lines 112 that are each configured to carry display data signals for operating one or more display pixels 116 of the display connected to the data lines 112. For example, the data lines 112 may be conductive traces or other conductive physical pathways that carry data signals to the display pixels 112 of the display 110 for operating the display pixels 112 to generate display content on the display 110. Although Figure 1 Although not shown, it should be understood that the display 110 may also include one or more other control lines (such as address lines) that are connected to the display pixels 116 and arranged substantially perpendicular to the data lines 112. Figure 1 As shown, in one or more specific implementations, two speakers 114 can be disposed adjacent to each of one or more of the data lines 112 (e.g., behind or below the data lines). In this example, the two speakers 114 are disposed adjacent to a first of the data lines 112 on the left side of the electronic device 100, and the two speakers 114 are disposed adjacent to a second of the data lines 112 on the right side of the electronic device 100. In other examples, more than two speakers (e.g., multiple pairs of speakers) can be disposed adjacent to one or more of the data lines 112.

[0019] In one or more use cases, the speakers 114 may be configured to output a stereo (or spatial) output, wherein two speakers 114 disposed adjacent to a first of the data lines 112 on the left side of the electronic device 100 output a first channel (e.g., a left channel) of the stereo (or spatial) output, and two speakers 114 disposed adjacent to a second of the data lines 112 on the right side of the electronic device 100 output a second channel (e.g., a right channel) of the stereo (or spatial) output.

[0020] exist Figure 1 In the example of FIG. 1 , the electronic device 100 can be implemented using a housing that is small enough to be portable and carried or worn by a user (e.g., Figure 1 The electronic device 100 may be a handheld electronic device such as a tablet computer or a cellular phone or a smart phone, or a wearable device such as a smart watch, a hanging device, a headlamp device, etc.). However, Figure 1 The configuration of the electronic device 100 is merely illustrative. In other implementations, the electronic device 100 may be a computer, such as a computer integrated into a display (such as a computer monitor), a laptop computer, a media player, a gaming device, a navigation device, a computer monitor, a television, headphones, earbuds, or other electronic equipment. As discussed herein, in some implementations, the electronic device 100 may be provided in the form of a wearable device such as a smart watch. In one or more implementations, the housing 106 may include one or more interfaces for mechanically coupling the housing 106 to a strap or other structure for securing the housing 106 to the wearer.

[0021] Figure 2 Illustrated Figure 1 A cross-sectional side view of a portion of electronic device 100 is shown. Figure 2 In the example of FIG. 1 , two speakers 114 are shown adjacent to one of the data lines 112 in the display 110. Figure 2 As shown, data lines 112 may be coupled to display circuitry 230 (e.g., a display data driver) of display 110. Data lines 112 may carry data signals generated by display circuitry 230 to one or more display pixels of display 110 (e.g., in response to receiving display content for display from other device circuitry of electronic device 100).

[0022] like Figure 2As shown, each of the speakers 114 may include a front volume 209 and a rear volume 211. The front volume 209 and the rear volume 211 may be separated by a sound generating component 215 (e.g., a diaphragm or an actuatable component of a micro-electromechanical system (MEMS) speaker). In one or more specific implementations, the sound generating component 215 may be mechanically coupled to the voice coil 203 so that when the voice coil 203 moves (due to the interaction of the field generated by the current in the voice coil with the magnetic field of the magnet 205), the sound generating component 215 moves to generate sound.

[0023] As shown in the figure, Figure 2 The sound generating components 215 of each of the speakers 114 in the electronic device 100 are oriented in the same direction to generate audio output (e.g., project sound) in the same direction (e.g., toward and / or through the display 110). In one or more implementations, the speakers 114 can be mounted within fifty millimeters (e.g., within twenty millimeters, within ten millimeters, within two millimeters, or within one millimeter of the display 110). In one or more implementations, the speakers 114 can be mounted to the display 110 or can be mounted to another internal structure of the electronic device 100 and separated from the display 110 by an air gap.

[0024] exist Figure 2 In the example of , each speaker in the speaker 114 includes a speaker circuit 222. As discussed in further detail below, the speaker circuit 222 may include, for example, a voice coil 203, a magnet 205, and / or other speaker circuits. In one or more specific implementations, the electronic device 100 may also include other circuits such as a device circuit 224. The device circuit 224 may include one or more processors, memories, acoustic components, tactile components, mechanical components, electronic components, or any other suitable components of an electronic device. In one or more specific implementations, the device circuit 224 may also include one or more sensors, such as an inertial sensor (e.g., one or more accelerometers, gyroscopes, and / or magnetometers), a heart rate sensor, a blood oxygen sensor, a positioning sensor, a microphone, and the like. In one or more specific implementations, the device circuit 224 may include one or more amplifiers configured to provide a control signal to the speaker 114 (e.g., by providing a modulated control current via the voice coil 203 of the speaker 114).

[0025] As shown, speaker 114 may be mounted adjacent to data line 112 of display 110. Because speaker circuit 222 includes electromagnetic components (e.g., a magnet and a voice coil), operating speaker 114 may generate an electromagnetic field that may corrupt and / or otherwise interfere with data signals in data line 112. In some scenarios, such electromagnetic interference may result in visible artifacts on display 110.

[0026] According to aspects of the subject disclosure, two speakers 114 mounted adjacent to the same data line 112 can be configured to mitigate electromagnetic interference to the data line 112 and / or the display 110. For example, two speakers 114 mounted adjacent to the same data line 112 can be operated acoustically and mechanically in phase, and electrically out of phase. In this way, electromagnetic interference from one speaker 114 can be partially or completely canceled by another speaker 114.

[0027] For example, Figure 3 As shown, the first speaker 114A and the second speaker 114B can be oriented in the same direction 300. For example, in one or more specific implementations, the orientation of the speaker can be defined by the direction of movement 309 of the voice coil of the speaker (e.g., toward and away from the front of the speaker) and / or the orientation of the diaphragm of the speaker (e.g., which can control the main direction of the sound output by the speaker). For example, the sound generating components 215 (such as diaphragms) of both the first speaker 114A and the second speaker 114B can be oriented in the same direction (e.g., parallel) to project sound in substantially the same direction 300 (or in substantially parallel directions). For example, the diaphragm of each speaker can have an inner surface facing the rear volume 211 and an outer surface facing the display 110. In one or more specific implementations, the orientation of the speaker can be defined by the direction facing the outer surface of the diaphragm. In one or more specific implementations, the orientation direction of the speaker 114 can be defined as a direction extending through the center of the speaker and from the outer surface of the diaphragm toward the display 110.

[0028] As an example, the first speaker 114A and the second speaker 114B can represent Figure 2 The two speakers 114 can represent Figure 1 The two rightmost speakers 114 or Figure 1 The two leftmost speakers 114 (e.g., two speakers 114 adjacent to the same data line 112) may be arranged such that the first speaker 114A may have a first magnet 205A oriented in a first polarity orientation, and the second speaker 114B may have a second magnet 205B oriented in a second polarity orientation substantially opposite to the first polarity orientation. For example, in Figure 3 In the embodiment, the north (N) pole of the first magnet 205A of the first speaker 114A may be arranged closer to the front of the first speaker 114A (e.g., closer to the sound generating component 215) than the south (S) pole of the first magnet 205A, and the south (S) pole of the second magnet 205B of the second speaker 114B may be arranged closer to the front of the second speaker 114B (e.g., closer to the sound generating component 215) than the south (S) pole of the second magnet 205B.

[0029] As shown, the voice coil 203A of the first speaker 114A can be formed by one or more windings of wire 302, so that the first magnet 205A is disposed within the open hole of the coil formed by the windings of wire 302. In order to actuate the sound generating component 215 of the first speaker 114A (see, e.g., Figure 2 ), a control current (e.g., modulated according to desired audio content to be output by the first speaker 114A) may be passed through the voice coil 203A (e.g., through windings of the wire 302). The changing magnetic field within the coil induced by the control current combines with the magnetic field of the first magnet 205A (e.g., which may be fixed in place) to cause the voice coil 203A to move relative to the fixed position of the first magnet 205A. The sound generating component 215 of the first speaker 114A may be mounted to or otherwise mechanically coupled to the voice coil 203A such that movement of the voice coil 203A relative to the first magnet 205A causes the sound generating component 215 to move and generate sound (e.g., project sound in the direction 300).

[0030] The voice coil 203B of the second speaker 114B may be formed by one or more windings of the wire 303, such that the second magnet 205B is disposed within the open bore of the coil formed by the windings of the wire 303. To actuate the sound generating component 215 (e.g., see Figure 2 ), a control current (e.g., modulated according to desired audio content to be output by the second speaker 114B) may be passed through the voice coil 203B (e.g., through the windings of the wire 303). The changing magnetic field within the coil induced by the control current combines with the magnetic field of the second magnet 205B (e.g., which may be fixed in position) to cause the voice coil 203B to move relative to the fixed position of the second magnet 205B. The sound generating component 215 of the second speaker 114B may be mounted to the voice coil 203B such that movement of the voice coil 203B relative to the second magnet 205B causes the sound generating component 215 of the second speaker 114B to move and generate sound (e.g., project sound in the direction 300).

[0031] Because the first magnet 205A is oriented differently from the second magnet 205B, in order to cause the first speaker 114A and the second speaker 114B to output the same audio content simultaneously (e.g., in order to operate the first speaker 114A and the second speaker 114B acoustically in phase), the control current in the voice coil 203A may be different (e.g., equal in magnitude and opposite in direction) from the control current in the voice coil 203B. Figure 3As shown, the control current in the voice coil 203A can be provided in a first direction 304 (e.g., into the page to the left of the first magnet 205A and out of the page to the right of the first magnet 205A), and the control current in the voice coil 203B can be provided in a second direction 306 that is substantially opposite to the first direction 304 (e.g., out of the page to the left of the second magnet 205B and out of the page to the right of the second magnet 205B). In this way, the control currents in the voice coil 203A and the voice coil 203B can cause the voice coil 203A and the voice coil 203B (e.g., and the corresponding sound generating components 215 attached thereto) to move in the same manner at the same time (e.g., mechanically in phase), while the magnetic field generated by the voice coil 203A can be substantially out of phase (e.g., substantially equal in magnitude and substantially opposite in direction, such as one hundred and eighty degrees out of phase) with the magnetic field generated by the voice coil 203B.

[0032] In various implementations, providing control currents in the first speaker 114A and the second speaker 114B in substantially opposite directions may be achieved by providing opposite currents to the voice coil 203A and the voice coil 203B from one or more amplifiers (e.g., from the device circuit 224) or by winding the wire 303 of the voice coil 203A in a direction opposite to the winding direction of the wire 302 of the voice coil 203B. For example, Figure 4 An exemplary implementation is illustrated in which the wire 302 of the voice coil 203A is wound in the same direction as the wire 303 of the voice coil 203B (e.g., both the wire 302 and the wire 303 may be wound in a right-hand winding direction, such as in Figure 4 In the example, or both wire 302 and wire 303 can be wound in a left-hand winding direction), and control current is input into each voice coil in the opposite direction (e.g., as controlled by one or more amplifiers such as an amplifier of device circuit 224).

[0033] Another example: Figure 5 An exemplary implementation is illustrated in which the wire 302 of the voice coil 203A and the wire 303 of the voice coil 203B are wound in substantially opposite directions. Figure 5 In the example of FIG. 1 , the wire 302 of the voice coil 203A is wound in a right-hand winding direction, and the wire 303 of the voice coil 203B is wound in a left-hand winding direction. As shown, in this configuration, the same control current can be provided to the voice coil 203A and the voice coil 203B, and substantially opposite (e.g., electrically out of phase) flows of current in the voice coil 203A and the voice coil 203B can be caused by the different winding directions of the two voice coils.

[0034] Figure 6 This example shows that Figure 314A and 14B in an arrangement of FIG. 14B. As shown, the magnetic field generated by the first speaker 114A (e.g., relative to the first speaker 114A) may be substantially opposite in direction (e.g., and equal in magnitude) to the magnetic field generated by the second speaker 114B (e.g., relative to the second speaker 114B). Figure 6 In the example of FIG. 1 , it can be seen that the plurality of data lines 112 pass through both the first speaker 114A and the second speaker 114B (e.g., pass in front of and / or over the sound generating component 215). In this arrangement, any effect of the magnetic field of the first speaker 114A or the second speaker 114B on the data transmitted through the data line 112 can be substantially cancelled by the magnetic field of the other of the first speaker 114A or the second speaker 114B.

[0035] exist Figures 3 to 6 In examples of the present invention, the first speaker 114A and the second speaker 114B may be disposed on a common side of the electronic device 100 (e.g., both on the left side or both on the right side), or both may be disposed at or near the center of the electronic device 100. In these examples, the first speaker 114A and the second speaker 114B may be operated to output the same audio content. For example, both the first speaker 114A and the second speaker 114B may be operated to output the left channel of a stereo output or a spatial output, both the first speaker 114A and the second speaker 114B may be operated to output the right channel of a stereo output or a spatial output, or both the first speaker 114A and the second speaker 114B may be operated to output the center channel of a stereo output or a spatial output. In these examples, the first speaker 114A and the second speaker 114B may be operated acoustically and mechanically in phase, and electrically out of phase, as described herein, to output the same audio content.

[0036] In one or more implementations, an electronic device (such as electronic device 100) can be capable of rotating from one orientation (e.g., portrait or landscape orientation) to another orientation (e.g., landscape or portrait orientation). Figure 7 The electronic device 100 is illustrated in Figure 1 The orientation shown is a use case in which the orientation is rotated approximately ninety degrees. In one or more specific implementations, the electronic device 100 can be configured to modify the video and / or audio content output by the electronic device in response to a change in the device orientation. For example, in Figure 1 The electronic device is outputting video content on the display 110 and audio content from the speaker 114 and is rotating to Figure 7In the use case of the orientation of the electronic device 100, the electronic device (e.g., device circuitry 224) can rotate the video content on the display 110 (e.g., and / or adjust the size, resolution, etc.). In this use case, the electronic device 100 can also modify the output of the speaker 114 in response to the change in the device orientation.

[0037] For example, the two rightmost speakers 114 may be Figure 1 The right channel of the stereo output is output in the orientation of Figure 1 However, when the electronic device 100 is rotated to Figure 7 When the orientation is such that Figure 1 The two bottom most speakers 114 (eg, rotated to Figure 7 on the right side of the device) is operated to Figure 7 The orientation outputs the right channel of the stereo output, and Figure 1 The two top speakers 114 (eg, rotated to Figure 7 The left side of the device in the image is operated to output the left channel of the stereo output.

[0038] However, if Figure 7 As shown, the data line 112 rotates with the electronic device 100. For this reason, if two speakers 114 adjacent to the same data line are operated to output different audio content, it may be difficult or impossible to electrically operate the two speakers in phase to mitigate the impact on the data line 112. In one or more specific implementations, the electronic device 100 (e.g., the device circuit 224) may further modify the audio content to allow (e.g., continue) the audio content to be played in the same phase as the data line 112. Figure 7 The invention can reduce interference with the data line 112 of the display 110 in the orientation of the display 110. For example, a magnetic field that changes with a specific frequency or within a specific frequency range can be predetermined to be most likely to interfere with the data line 112 of the display 110. Therefore, in one or more specific implementations, the electronic device 100 can modify a portion (such as a frequency band) of the left and right channels of the stereo output to form a mono channel in the frequency band. The mono channel within the frequency band can then be output by two speakers 114 adjacent to the same data line 112 (for example, even when these speakers are arranged on the left and right sides of the electronic device 100), so that at least in the frequency band, the two speakers 114 adjacent to the same data line 112 can operate acoustically and mechanically in phase, and electrically out of phase. In one or more specific implementations, other portions of the stereo output (such as other frequency bands) can remain split between the two speakers 114 along the same data line 112 (for example, left and right).

[0039] In one or more embodiments, if two different channels of audio content being output by two speakers 114 adjacent to the same data line 112 are highly correlated (e.g., for a scene in a video where the sound source is directly in front of or behind a viewer), the electronic device 100 may operate the two speakers 114 adjacent to the same data line 112 acoustically and mechanically in phase and electrically out of phase without modifying the audio content of the two different channels.

[0040] Figure 8 A flowchart illustrating an example process for operating an acoustic transducer system of an electronic device having a display according to one or more specific implementations is illustrated. For the purpose of explanation, this document mainly refers to Figure 1 and Figure 2 The process 800 is described with reference to the electronic device 100. However, the process 800 is not limited to Figure 1 and Figure 2 800, and one or more blocks (or operations) of process 800 may be performed by one or more other components or other suitable devices. Further for the purpose of explanation, the blocks of process 800 are described herein as occurring sequentially or linearly. However, multiple blocks of process 800 may occur in parallel. In addition, the blocks of process 800 do not have to be performed in the order shown, and / or one or more blocks of process 800 do not have to be performed and / or may be replaced by other operations.

[0041] exist Figure 8 In an example of, at block 802, a first speaker (e.g., first speaker 114A) oriented in a first direction (e.g., direction 300) may be operated (e.g., by an electronic device (such as electronic device 100) in which the first speaker is disposed). For example, the first speaker may include a first magnet (e.g., first magnet 205A) oriented in a first polarity orientation. For example, the first polarity orientation may be defined by the north (N) pole of the first magnet being closer to a diaphragm (e.g., sound generating component 215) of the first speaker than the south (S) pole of the first magnet. For example, operating the first speaker may include projecting sound corresponding to audio content primarily in the first direction by the first speaker oriented in the first direction.

[0042] At block 804, a second speaker (e.g., second speaker 114B) oriented in a first direction (e.g., direction 300) may operate acoustically and mechanically in phase with the first speaker and electrically out of phase with the first speaker. For example, the second speaker may include a second magnet (e.g., second magnet 205B) oriented in a second polarity orientation substantially opposite to the first polarity orientation (e.g., as described herein in conjunction with Figure 3For example, the second polarity orientation may be defined by the north (N) pole of the first magnet being further from the diaphragm (e.g., sound generating component 215) of the second speaker than the south (S) pole of the second magnet. For example, operating the second speaker may include projecting additional sound corresponding to the audio content primarily in the first direction by the second speaker oriented in the first direction.

[0043] In one or more specific implementations, a first speaker may have a first voice coil wound in a first direction, and a second speaker may have a second voice coil wound in a second direction substantially opposite to the first direction (e.g., to operate the second speaker acoustically and mechanically in phase with the first speaker and electrically out of phase with the first speaker), such as in Figure 5 In one or more other specific implementations, the first speaker may have a first voice coil wound in a first direction, and the second speaker may have a second voice coil wound in the first direction (e.g., as in Figure 4 ), and current may be provided via the first voice coil (e.g., by an amplifier) ​​in a direction substantially opposite to the first direction (e.g., to operate the second speaker acoustically and mechanically in phase with the first speaker and electrically out of phase with the first speaker).

[0044] In one or more specific implementations, when the first speaker and the second speaker are operated, a display (e.g., display 110) including at least one data line (e.g., data line 112) passing through (e.g., in front of) the first speaker and the second speaker can also be operated (e.g., to output video content corresponding to the audio content being output by the first speaker and the second speaker, such as an audio track of a video file for which the video track is being displayed). For example, operating the second speaker electrically out of phase with the first speaker can reduce electromagnetic interference of the first speaker (e.g., by operating the electromagnetic field generated by the first speaker) with the display.

[0045] In one or more specific implementations, operating the second speaker electrically and mechanically in phase with the first speaker and electrically out of phase with the first speaker may include passing a first current through a first voice coil of the first speaker in a first current direction and passing a second current through a second voice coil of the second speaker in a second current direction (e.g., as described herein in conjunction with Figure 3 , Figure 4 and / or Figure 5 described above).

[0046] In one or more implementations, operating the first speaker and the second speaker may include operating the first speaker and the second speaker in a first orientation (eg, Figure 1In one or more implementations, process 800 may further include operating the first speaker and the second speaker to output a first channel of a stereo output in response to the orientation of the device changing from the first orientation to the second orientation (e.g., Figure 7 The operation of the first speaker may be modified to output a portion of a second channel of the stereo output in response to a change in an orientation of the electronic device, such as a second orientation rotated approximately ninety degrees relative to the first orientation. For example, the change in orientation may cause the first speaker to rotate from one side (e.g., the right or left side) of the electronic device (e.g., relative to a user of the electronic device) to another side (e.g., the left or right side) of the electronic device, and to output at least a portion of a different channel (e.g., the left channel or the right channel) correspondingly based on the different positions of the first speaker (e.g., relative to a user of a device including the first speaker and the second speaker).

[0047] In one or more specific implementations, in response to a change in orientation: another portion of the second channel of the stereo output may be modified to generate a mono output. The first speaker and the second speaker may be operated to output a mono output (e.g., when the electronic device is in a second orientation). In this way, even in an orientation where the first speaker and the second speaker are disposed on different sides of the electronic device (e.g., and partially output different channels of audio content), at least a portion of the operation of the first speaker and the second speaker (e.g., a portion corresponding to the mono output) may be kept acoustically and mechanically in phase, and electrically out of phase. For example, a portion of the second channel may include a first frequency band of the second channel, and another portion of the second channel may include a second frequency band of the second channel. For example, the second frequency band may include one or more frequencies that are predetermined to affect a display of a device (e.g., electronic device 100) that includes the first speaker and the second speaker.

[0048] In one or more specific implementations, process 800 may also include identifying another portion of the stereo output based on the audio content in the stereo output. For example, the electronic device 100 may determine that the audio content in the first channel is substantially uncorrelated with the audio content in the second channel. The electronic device may then identify another portion of the stereo output in the second frequency band for modification in response to determining that the first channel is substantially uncorrelated with the audio content in the second channel (e.g., and the operation of the first speaker and the second speaker will therefore not be one hundred and eighty degrees out of phase). A portion of the audio content of the first channel (e.g., a portion in the second frequency band) may also be modified to a mono output. For another example, the electronic device may determine that the audio content in the first channel is highly correlated with the audio content in the second channel, and may operate the first speaker to output the second channel (e.g., without modification) and operate the second speaker to output the first channel (e.g., without modification).

[0050] The bus 908 generally represents all system buses, peripheral busses, and chipset buses that communicatively connect the many internal devices of the electronic system 900. In one or more specific implementations, the bus 908 communicatively connects one or more processing units 912 with the ROM 910, the system memory 904, and the permanent storage device 902. The one or more processing units 912 retrieve instructions to be executed and data to be processed from these various memory units in order to perform the processes disclosed in the present subject matter. In different specific implementations, the one or more processing units 912 can be a single processor or a multi-core processor.

[0051] ROM 910 stores static data and instructions required by one or more processing units 912 and other modules of the electronic system 900. On the other hand, permanent storage device 902 can be a read-write memory device. Permanent storage device 902 can be a non-volatile memory unit that stores instructions and data even when the electronic system 900 is turned off. In one or more specific implementations, a mass storage device (such as a magnetic disk or optical disk and its corresponding disk drive) can be used as permanent storage device 902.

[0052] In one or more specific implementations, a removable storage device (such as a floppy disk, a flash drive and its corresponding disk drive) can be used as the permanent storage device 902. Like the permanent storage device 902, the system memory 904 can be a read-write memory device. However, unlike the permanent storage device 902, the system memory 904 can be a volatile read-write memory, such as a random access memory. The system memory 904 can store any of the instructions and data that one or more processing units 912 may need at runtime. In one or more specific implementations, the processes disclosed in the subject matter are stored in the system memory 904, the permanent storage device 902, and / or the ROM 910. The one or more processing units 912 retrieve instructions to be executed and data to be processed from these various memory units in order to perform the processes of one or more specific implementations.

[0053] The bus 908 is also connected to an input device interface 914 and an output device interface 906. The input device interface 914 enables a user to transmit information and select commands to the electronic system 900. Input devices that can be used with the input device interface 914 may include, for example, a microphone, an alphanumeric keyboard, and a pointing device (also referred to as a "cursor control device"). The output device interface 906 may, for example, enable the display of images generated by the electronic system 900. Output devices that can be used with the output device interface 906 may include, for example, printers and display devices, such as liquid crystal displays (LCDs), light emitting diode (LED) displays, organic light emitting diode (OLED) displays, flexible displays, flat panel displays, solid-state displays, projectors, speakers or speaker modules, or any other device for outputting information. One or more specific implementations may include devices that act as both input devices and output devices, such as touch screens. In these specific implementations, the feedback provided to the user may be any form of sensory feedback, such as visual feedback, auditory feedback, or tactile feedback; and input from the user may be received in any form, including acoustic, voice, or tactile input.

[0054] Finally, if Fig. 9 As shown, bus 908 also couples electronic system 900 to one or more networks and / or to one or more network nodes via one or more network interfaces 916. In this manner, electronic system 900 may be part of a computer network, such as a LAN, a wide area network ("WAN"), or an intranet, or may be part of a network of networks, such as the Internet. Any or all components of electronic system 900 may be used with the subject disclosure.
