DETAILED DESCRIPTION OF THE INVENTION
The present invention discloses an electronic device in which a layer of resonating material is used to enable handling audio waves, for example when receiving, outputting or analyzing the audio waves, or when converting audio waves into computerized audio signals. The layer of resonating material may be connected to a computerized control unit to identify the resonance of the layer in order to extract attributes of the sound waves that resulted in resonance when hitting the layer of resonating material.
In some cases, at least a portion of the smart layer is manufactured differently than other parts of the object made from similar materials (for example, but not limited to, an object that contains smart material elements from glass in other glass elements). The layer of resonating material may be made from different materials, may be made in different density, may be made with a different thickness, may be made with a different electricity conductivity, may include different sensors, may be coated and/or painted over with different materials, may be an integral part of another material, but may be subject to different processes during the manufacturing and/or assembly of the device. The layer of resonating material may be in the form of a glass that is an integral part of a screen display unit glass, or the device' s body. The layer may be manufactured in such manner to include a control unit. The layer may be produced in such manner to include a frequency vibration sensor.
The layer of smart material may function as a speaker. In such a case, sound waves transferred through the layer are amplified by the layer of smart material and can be heard or detected in a remote device. The layer of smart material may function as an amplifier. In such a case, sound waves transferred through the layer are amplified. The amplification may be used to improve the quality of sound, and/or increase the audio volume of the speaker. The layer of smart material may function as a microphone. In such a case, sound waves that hit the layer cause the layer to resonate, and said resonance (or vibration) can be detected or sensed. The layer of smart material may function as an amplifier.
The layer of resonating material comprises a material resonating responsive to sound waves, such as glass, fabric, synthetic or organic, the material may be coated, painted, may be made of a combination of materials or any material desired by a person skilled in the art, from which information concerning audio signals can be extracted. The layer of resonating material may be optimized to accommodate sound wave in frequencies that can be heard or generated by a human being, or according to predefined rules, such as behavior of a predefined device or environment. Such optimization may refer to materials used in the layer, audio processing, sensing audio signals and the like. The layer of resonating material may be connected to an electronic component, sensor, controller, processor, device and the like, in order to either activate the layer of resonating material, to receive data from the layer of resonating material or to control the layer of resonating material.
The layer of resonating material may be connected - wirelessly or wired - to a remote electronic device, such as a sensor, used to sense incoming sound wave, for example, incoming sound wave that are generated by the voice of the user, thus enabling the smart material to function as a microphone. The remote electronic device may be a processor and/or controller configured to process the captured sound from the sensor, and translate the captured sound to audio data. The sensor may be used to test the status of the layer of resonating material. For example, the sensor can be used to check if there are any cracks in the glass that is the smart material, or coated and/or painted over by the smart material.
The remote device may be a control unit. The control unit may be used to generate vibrations in at least a portion of the layer of resonating material, in predefined audio attributes such as frequencies and order, in such manner that vibrations of the layer of resonating material generate sound from the material in accordance to the audio data. The glass vibrations can differ in their frequencies, strength and additional measurable parameters. The control unit may be connected to other components to receive audio-related data and frequency-related data;
The control unit may be used to generate specific vibrations on the layer of resonating material that can be sensed in a predefined quality by the sensors, in such manner that the sensed data can be used to detect cracks or other abnormalities in the layer of resonating material, for example when compared to older measurements.
The layer of resonating material can have directional capabilities, for example by sensing sound wave hitting the layer of resonating material from a specific direction or from various directions. Such directional capabilities may be used as a directional microphone. The layer of resonating material may be placed, manufactured, integrated, or designed in such manner that it amplifies sounds towards a specific direction more than it amplifies sound waves towards other directions, thus functioning as a directional speaker's amplifier. The layer of resonating material may be connected to a computerized or electronic module configured to detect the relative position of the user of the mobile electronic device versus an object with the layer of resonating material, and selectively shift performance to a material portion that is closer to the user.
The layer of resonating material may be connected to a proximity detection unit used to detect if an object is close or touching the layer of resonating material. In such a case, the control unit may selectively relocate the function to another section of the layer of resonating material which is not blocked or interfered by the detected object. The layer of resonating material may be connected - wirelessly or wired - to a sensor that can detect the temperature near the layer of resonating material, for example when heat is generated from the object and/or performance of the layer of resonating material. The control unit may selectively switch performance to other portions of the layer of resonating material in the mobile electronic device if a specific portion of the layer of resonating material has heated in such manner that its performance was affected, or beyond a predefined threshold. The control unit may selectively apply cooling means, to cool a specific smart material portion.
FIG. 1A shows a mobile electronic device, in accordance with a preferred embodiment of the invention. The mobile electronic device 100 comprises a body 110 and a display unit 120. The body may be covered with a case. At least a portion of the display unit 120 may be made of glass or another vibrating material.
FIG. IB shows a mobile electronic device comprising a layer of smart material for enhancing audio functions, in accordance with a preferred embodiment of the invention. The layer of smart material may be used as a speaker 130 of the device 150 or in a microphone 140 of the device. The layer of smart material may be connected to a computerized unit for analysis of the layer's vibration.
FIG. 1C shows a mobile electronic device comprising a layer of smart material attached to or coated on a display unit, in accordance with a preferred embodiment of the invention. The mobile electronic device 160 comprises a body 165 covering the display unit 180. The body 165 comprises a microphone unit, for example in the top segment 170 and bottom segment 175 of the body 165. The display unit 180 comprises four (4) different areas 182, 185, 188, 190 covered by a layer of smart material, for enhancing the processing of audio waves. The different areas 182, 185, 188, 190 may function as speakers. In some cases, the layer of resonating material comprises glass as the resonating material. The glass may be dedicated to be used as either a speaker, microphone or both, may be manufactured differently than other parts of the device made from glass. For example, but not limited to, the glass portion can be made from different materials, may be made in different density, thickness, electronic conductivity, may include different sensors, may be coated or painted, may be subject to different processes during the manufacturing and/or assembly of the device. The mobile electronic device may include means to effect the glass features in such manner that its performance as a speaker or as a microphone or both will change. For example, said electronic device may include heating and/or cooling means that can heat or cool the said glass, and change its performance accordingly;
FIGS. 2A and 2B show a layer of smart material equipped with sensors, in accordance with a preferred embodiment of the invention. The layer of smart material 215 may be embedded in a sheet 210 of another material, for example a layer of glass 215 may be embedded in a layer of metal or plastics used to manufacture an electronic device, or any assembly, for example a wall or a window frame. The layer of glass 215 may resonate responsive to sound waves hitting it, or responsive to an electronic signal injected to it via wires. The sheet of material 210 may be attached to a second sheet 220 comprising sensors, 225, for example a volume sensor or a temperature sensor, and additional computerized modules 230, 235, such as a cooling unit 230 or any operational module 235 that changes the functionality of the layer of resonating material 215.
The electronic device may include more than one said glass portions that can operate simultaneously - for example, to include 4 such glass portions in the 4 corners of the font of the display unit's glass, so the display unit's glass also has 4 speakers in it. The electronic device may include a control mean that can selectively operate and change the glass performance, in accordance with the audio data it is capturing or transmitting. The electronic device may include sensor means to detect real-time touch points by a user, and selectively switch between different glass portions in the device. For example, if data from such touch sensor reflects that a user's finger is placed on a glass portion that is being used as a speaker, the control means may selectively switch the audio content to another glass portion, that is not touched. In another exemplary case, such sensors can indicate that the user is currently operating the device via the touch display unit - for example, writing an email - the control unit of the electronic device may switch the glass functionality (as a speaker and/or microphone) to another glass portions in the device, which are not in the display unit.
Figure 2B shows the layer of resonating material 245 embedded in a sheet 240 of another material. A plurality of sensors 255, 260, 265 is located in the vicinity of the layer of resonating material 245, for example embedded in second sheet 250 attached to the first sheet 240 of the another material. In some cases, the plurality of sensors 255, 260, 265 is and the layer of resonating material 245 are embedded in the same sheet of material, or located in a single compartment in an electronic device.
The sensors may be used to sense incoming sound wave, for example, incoming sound waves generated by the user, thus enabling the resonating material, such as a layer of glass, to function as a microphone. The electronic device may include a processor that can process the captured sound waves detected by the sensor, and translate the detected sound waves to audio data.
The control unit of the device may be used to generate specific vibration, configured to be sensed in a pre-defined quality by the sensors associated with the resonating material, in such manner that the sensed data can be used to detect cracks or other problems in the resonating material. In some cases, the electronic device is a smartphone placed on a table. When the user wishes to conduct a phone conversation, the sensor means may detect his relative position Vs the device, and the control means may switch the microphone and/or speaker functions to glass portions that are closer or optimal for use. The electronic device may include proximity detection sensor used to detect if an object of close or touching the device, and the control means will selectively relocate the function to other glass portions. For example, in one of the use case on the invention, said proximity sensor may detect that the electronic device is being placed in a protective covering case, in such manner that only the display unit is exposed during operation of the device. The control unit may selectively operate only those glass portions in the display unit.
The electronic device may include sensors that can detect the temperature or changes in temperature near the layer of resonating material, for example generated by the device's performance. The control unit may selectively switch performance to other glass portions in the device in a specific glass portion has heated in such manner that its performance was affected. The control unit selectively apply cooling means in the device, to cool a specific glass portion. The user of the electronic device may selectively program the glass portions in the device to perform a specific function. For example, but not limited to, the user may select specific glass portions to perform as microphones, and may assign such performance differently to each computerized application in the electronic device. In some cases, the user may select specific glass portions to perform as speakers, and may assign such performance differently to each computerized application in the electronic device.

A first electronic device 330 is located on a second electronic device 320 and audio signals are transferred between the two electronic devices via a layer of resonating material, such as glass, contained in at least one of the two electronic devices 330, 320. The second electronic device 320 may be mounted on a surface 310, such as a working desk.
In some cases, a system of the subject matter includes at least 2 having sensors as described above. The sensor may be contained or connected to at least one of the two devices, configured to capture the vibrations or resonance of a resonating material generated by sound waves, whether generated by the first electronic device 330 or by the second electronic device 320.
In some cases, the second electronic device 320 is used as an amplifier, for example when a resonating material of the first electronic device 330 is used to output the audio waves, and when in touch with a resonating material of the second electronic device 320, the audio is received by the second electronic device glass (being used as a microphone) or glass portions, and then said audio is transmitted or outputted via the second device glass. In some cases, the first electronic device 330 might be a media player, and it can be placed on a second device, which is a tablet, a smartphone or even a TV.
Figure 4 shows two electronic devices, at least one of them comprises a layer of resonating material and an indication unit, according to exemplary embodiment of the subject matter. The electronic device 410 is mounted on a surface and comprises several sections comprising resonating material that function as speakers or microphones. Segments 420, 422, 425 and 428 function as speakers. When outputting signals via the resonating materials, the indication unit may generate a visible indication, for example by changing the color of those segments, or by illuminating in a predefined color or direction. In some cases, the entire display unit may be covered with a green light when the speakers 420, 422, 425 and 428 output sound waves. Similarly, segments 430, 435 of the electronic device 410 comprise resonating material used as a microphone, to detect sound waves. When the segments 430, 435 operate as microphones, the indication unit generates light or another indication, for example an alert or a vibration.
The indication unit may generate a visible indication, for example, in the form of a color, shape, icon and the like. The indication may be different per functionality of the layer of resonating material, for example, when said resonating material is used as a speaker, its color might be red, and when used as a microphone, the indication may be blue. The indication may be limited to active portions or segments of the layer of resonating material, for example, a specific glass portion currently used as a microphone, be indicated by a blinking blue light. The indication unit may be controlled by the control unit, and be part of the display unit and/or be embedded in the layer of resonating material.

Figure 6 shows a vehicle comprising a layer of resonating material, according to exemplary embodiments of the subject matter. The vehicle 600 comprises a front segment 605, for example comprising an engine, a body 610 and a rear segment 620, for example comprising a luggage compartment. The body 610 comprises four (4) windows - front right window 615, rear right window 612, front left window 625 and rear left window 627. At least a portion of the four windows may comprise a layer of resonating material, so the windows may function as microphones, speakers, amplifiers and sensors as disclosed above.
In some cases, a window in the vehicle 600 may be coated and/or painted over with such resonating material. The resonating material may function as a microphone, for example when the resonating material is embedded in a window next to the driver and the driver turns to the window when speaking. The driver's voice may be transferred to the vehicle's speakers, whether integral speakers of the vehicle, a predefined speaker located near a passenger, or speakers that comprise the resonating material. In some other cases, the resonating material is embedded in a rear window, to amplify the driver's sound.
In another embodiment of the invention, sensors located in the car, that can detect the presence of a passenger (for example, weight sensors under the seats), can be used to direct the captured voice to the near speaker and window, and also to activate a specific window as a microphone. In other cases, the layer of resonating material may include touch-sensitive elements - and a user may activate different functions via the touch elements - for example, select a specific passenger location to whom he wants his voice directed to. In some other cases, the layer of resonating material may function, or integrate into, a display unit in the window. In such a case, the user may use touch sensitive means in the window to activate the display and to activate the layer of resonating materials. Figure 7 shows a layer of resonating material used as a sensor, according to exemplary embodiments of the subject matter. A vehicle 710 traveling on a road 700 comprises a window 720 with a layer of resonating material capable of identifying a direction from which the sound waves 730 are detected. The sound waves 730 may be from a bicycle 740, or a bicycle horn.
The sensor may be used to sense the surrounding of sensor, to detect movement, temperature, pulse, light and the like. The sensor may have directional capabilities, i.e. - be more sensitive to sound wave from specific directions. The layer of resonating material may be used as a sensor by sensing vibrations caused by the presence of sound waves from its surrounding environment. The layer of resonating material may be used to enable sound recognition, for example when configured, manufactured or integrated in such manner and/or from such materials that are more sensitive to pre-defined sound types, vibrations and/or frequencies. For example, the layer of resonating material, may be configured to be more sensitive to sounds generated by bicycles 740. When bicycles 740 sounds are "hitting" the smart material, a processing unit connected to the layer of resonating material may generate an indication to the diver concerning the bicycles 740 traveling near him, and he need to be aware.
The layer of resonating material can have directional capabilities. The indication may include an estimated direction of the origin of the bicycles 740 sound. The layer of resonating material may be configured or manufactured or integrated in such manner and/or from such materials that are more sensitive to human voice. A vehicle 710 comprising the layer of resonating material may be used to determine the location of passenger in the vehicle 710. For example, if a mother is driving, and there is an infant in the back seat, detection of sounds, recognizing them as persons, can be used to determine that there are only 2 persons in the car, and their relative position.
In some cases, the layer of resonating material may be used to authenticate a person or entity, to determine the identity of a user of an object utilizing such smart materials. For example, a vehicle security system may use the layer of resonating material to determine the identity of the person who wishes to enter or operate the vehicle 710 and to enable the activation of the vehicle 710 according to the sound wave signature. The processing unit connected to the layer of resonating material may determine the signature based on a sequence of pre-defined sound waves. For example, by requiring the user to record as a reference a specific sentence, when he is in a specific position vs. the layer of resonating material. Authentication of the audio signature will be performed when the user reproduces these sound waves in the same manner and matching is determined.
The layer of resonating material may be used as a filter to block audio signals, for example based on a sound signature or audio property such as frequencies, sounds in specific volume or another parameter desired by a person skilled in the art. The filter may be used to enable access or use of predefined sounds or sound wave frequencies and/or sounds in specific volume.
