• Haptics may be defined as tactile feedback technology that interacts with a user through his sense of touch by applying force or vibrations to a surface or object. Haptic feedback may be localized to a part of the screen.
• the device may have no conventional speaker.
• the device may drive only one of a set of actuators under the screen under some circumstances. For example, when a user is making a phone call, only one actuator may be driven, so as to produce sound from only one part of the screen, which may be held next to the user's ear. This helps to keep the sound localized to near the user's ear, which helps to prevent other individuals from hearing the phone call.
• Prototype Device It is possible to improve audio quality by selecting a 0.5mm glass screen thickness instead of a more conventional 0.8mm.
• New actuators We used new non-led actuators for the prototype that are closer to the mass producible actuator.
• the device uses Thermoplastic elastomer (TPE) surface material which is not that widely used in this kind of consumer electronics. The effect on wearing can be tested with the prototype.
• Thermoplastic elastomers (TPE) sometimes referred to as thermoplastic rubbers, are a class of copolymers or a physical mix of polymers (usually a plastic and a rubber) which consist of materials with both thermoplastic and elastomeric properties.
• Thermoplastic elastomers show both advantages typical of rubbery materials and plastic materials.
• the prototype device incorporates highly packed electronics which will increase the heat production compared to products currendy in the market. To distribute the heat evenly and to avoid heat spots the design has an aluminum center part. High surface temperatures were expected due to high amount of current consumed by the electronics and the prototype incorporates heating resistors for the expected amount of device power consumption.
• the mechanics trial prototype can serve as an antenna test and development platform later on.
• the prototype integrates the following parts:
• the design consists of several entities: engine board, main Flexible Printed Circuit (FPC), battery and audio actuators on display glass.
• FPC Flexible Printed Circuit
• the main components in the engine board are the two audio amplifiers LM48560 by National Semiconductors. They have the smallest package available for such amplifier.

• the external voltage boosting components (coil, diode and capacitor) provide the required 30V driving voltage for the audio actuators from battery voltage. Test points are added for audio input signals and 2-pin connector is added for easy audio actuator output connection.
• DIP switches are used for amplifier settings and input port selection. DIP switches are described in Figure 22 and electrical design details are presented in Figure 23.
• Linear Technology LTC1733 IC is used as a charging IC. It is a stand-alone Li-ion charger with programmable charging current suitable for USB charging. Charging current is set to 500mA with resistor R123. There is a green LED on board indicating the charging status: when the LED is on, charging is ongoing. See Fig. 24 for charging IC electrical design details.
• the main FPC includes the USB connector used for battery charging and board-to-board connector for engine board connection.
• the USB interface design includes standard protection components for ESD and over voltage protection. The electrical design details are presented in Figure 25.
• the design area with most emphasis is the window suspension design. Items that have negligible effect of the results are designed with less detail. For example cover snap-fit locking construction is not final and therefore the covers fixing is backed up with tape on most of the mechanical reliability tests.
• the device has two display windows made of Corning Gorilla glass.
• a 0.5 mm thick flat Gorilla glass was selected to further minimize the device thickness and to improve the audio performance.
• this was against the reliability recommendation to use minimum 0.8 mm thick glass instead. Verifying the reliability of this thin glass is one of the most important targets of the testing rounds.
• a 0.8 mm thick cylinder curved Gorilla glass was used for the device back side.
• Device front window working as the audio panel, is suspended by soft 0.75 mm thickness gasket material.
• This soft gasket allows the window to float and it also seals the back cavity. Note that the cover lip under the window is between the display module and the window at left and right side areas of the device. It is part of a critical thickness path of the device (see Figure 30).
• DMA components on the bottom and top end of device are be fixed by adhesive tapes to the bottom of the front window capacitive sensor sheet (see Figure 30). This type of DMA fixing is used for other window suspension constructions too.
• the front window suspension is designed by using soft TPE material top of device side walls. TPE comes under the window and the window is fixed to it by glue or adhesive. Window suspension parameters can be adjusted by a short elastic area of TPE near of the window side edges (see figure 31). At the same time soft TPE works as a back cavity air gasket.
• Front window suspension is designed by using a window frame. Window is fixed to the frame constantly by adhesive tape. There are six window suspension elements between the frame and side walls of the device in the design (see figure 33). Suspension elements are moulded from TPE material of shore 80A stiffness. The device side walls left and right have soft back cavity shielding lips isolating back cavity from the free front side.
• Design proposal 2 was selected for mechanical trial as the most viable solution for ID and audio performance.
• THD Total Harmonic Distortion
• maximum sound pressure at 5% THD is measured in loudspeaker mode.
• the amplifier is also evaluated for maximum output level as a new amplifier design is used to save space. Previous aluminium prototype is also evaluated for reference with the new amplifier design to obtain best possible comparability.
• the target is to reach similar loudness level as in products on the market in this category.
• Samsung Galaxy S has been used as a reference.
• Cellular phone type approval sets requirements for loudness in handset mode (phone held against the ear) which was not evaluated in this case. The reason behind is discussed more precisely in the conclusions chapter.
• the prototype is placed in an anechoic chamber and acoustic output is measured with both channels driven by the internal amplifier. Microphone is placed on 10 cm distance from the center of display.
• THD is at expected level with maximum input to amplifier and sharp peaks can be avoided with proper tuning.
• Overall THD performance is not as good as with an average dynamic speaker, but adequate for the purpose. End user might not notice the difference - if peaks are counted out - but THD might be a stepping stone in regulative acceptance perspective.

• Curved bar form factor display device e.g. phone
• the bar form factor display device (eg. a phone) may have a unique and organic shape— essential for rapid product differentiation in a crowded space. Examples are shown in Figures 3 and 4.
• the bar form factor display device may have a concave front face and a convex rear face. The magnitude of the curvature of the faces may be the same or similar.
• the concave front may match the path of a finger as the user's wrist rotates. Hence it's very natural to use. Having a curved surface as the vibrating distributed mode loudspeaker (DML) speaker is also better since if the front display with the speaker exciters was instead a flat surface, then it would sound unpleasant if that flat surface is placed down against a tabletop. Curving the surface prevents this happening.
• DML distributed mode loudspeaker
• Preferred curvature of front and back is cylindrical, but spherical or aspherical are possible.
• the convex back can have a bistable display. Since the normal resting position is front face down, the back screen with bi-stable display is normally displayed when bar form factor display device is in the resting position. This resting position is mechanically stable. If bar form factor display device is placed back down (ie convex face down), the bar form factor display device could spin, which is unstable. Hence a user will likely place bar form factor display device front face (i.e. concave face) down, with the bi-stable screen showing.
• the front face can face inwards, since this better matches leg curvature. This can be the better configuration (as opposed to front face up) for antenna reception.
• the curved shape may be laminated to glass.

• a WiFi connection from a WiFi dongle with a USB interface; a mobile device can then interface to a memory in the WiFi dongle, plus any external device that the USB dongle is plugged into, just as though the USB interface was native to the mobile device. So you could view the file structure of files stored on the USB dongle itself in a web browser on the mobile device, or print to a printer the USB dongle is interfaced to, or print to a printer the mobile phone is connected to, for example.
• the mobile device eg. mobile phone
• In-vehicle (eg. in-car) audio systems often have USB interfaces for MP3 files, but have no way of accessing internet radio (that is currendy only available on really high-end systems).
• a wireless data enabled USB dongle that can receive streaming radio (e.g. for internet radio stations, Spotify etc.)
• the wireless data enabled USB dongle may interface wirelessly with a mobile phone or other mobile device.
• the mobile phone or other mobile device may provide automatic wireless network sharing.
• the mobile phone or other mobile device may provide wireless access to the internet, thereby providing access via the internet to radio stations that cannot be received by a vehicle radio broadcast receiver.
• the USB dongle captures a data stream and converts it to a sequence of files— just like the MP3 files the in-vehicle (eg.
• in-car audio is designed to read. This enables even a basic in-vehicle (eg. in-car) audio device to have playback/rewind, store etc. functionality for internet radio.
• the streamed audio is stored as at least two separate files, which allows the user to choose to skip to the next track using the car audio system software.
• the user can listen to music online in his vehicle (eg. a car) with no modifications to the in-vehicle (eg. in-car) audio system.
• An online interface is used for setting up the service, selecting stream source.
• the online interface may be provided by the mobile phone or other mobile device.
• the mobile device eg. mobile phone
• the mobile device may present a seamless, unibody surface—although it can still have hidden mechanical buttons e.g. for volume up, volume down.
• the mobile device eg. mobile phone
• the mobile device may be turned on or off by squeezing it.
• the mobile phone has a concave front face and a convex rear face, which may be of same or similar magnitude of curvature.
• Concave front may match a path of a finger as wrist rotates. Hence it's very natural to use.
• Having a curved surface as the vibrating distributed mode loudspeaker (DML) speaker is also better since if the main screen (eg. LCD) with the speaker exciters was instead a flat surface, then it would sound unpleasant if that flat surface is placed down against a tabletop. Curving the surface prevents this happening.
• Preferred curvature of front and back is cylindrical, rather than spherical or aspherical.
• the convex back can have a bistable display. Since the normal resting position is front face down, the back screen with bi-stable display is normally displayed when phone is in the resting position. This resting position is stable. If phone is placed back down (ie convex face down), the phone could spin, which is unstable. Hence a user will likely place phone front face (i.e. concave face) down, with the bi-stable screen showing. When the phone is in a pocket, the front face (concave face) can face inwards, since this better matches leg curvature. This can be the better configuration (as opposed to front face up) for antenna reception.

• WiMAX 2 has been . approved by ITU into the IMT Advanced family. WiMAX 2 is designed to be backward compatible with WiMAX 1/1.5 devices. Most vendors now support ease of conversion of earlier 'pre-4G', pre-advanced versions and some support software defined upgrades of core base station equipment from 3G.
