Description

Two-wheeled vehicle with glass diaphragm speakers

The present invention relates to a transportation vehicle, in particular to a two-wheel vehicle with a glass diaphragm speaker.

With the development of technology, speakers are installed in various devices. In the existing technology, if a traditional speaker needs better sound effects, the speaker is larger and occupies a larger space. If the speaker is too small, it cannot achieve good sound effects. Speakers are usually installed in the corner area of the display panel, which not only takes up space but also cannot provide a good auditory experience. Currently, most electronic device displays are full-screen designs, and the space left for speakers is getting smaller and smaller. Planar speakers have a planar voice coil, and the magnets are concentrated on one or both sides of the diaphragm, and the diaphragm vibrates in the magnetic field formed by it. The electrical signal is connected to the printed circuit on the diaphragm, and the current is orthogonal to the magnetic field generated by the permanent magnet, which generates a force that complies with Faraday's law. Under the action of this force, the diaphragm vibrates and converts the AC current signal into a sound signal. For example, US Patent US 8447063 B2 discloses a flat, thin dynamic speaker, which is configured so that the motor unit and the suspension unit are on the same plane, reducing the thickness of the speaker. However, this technology is an outdated diaphragm technology.

Secondly, consumers nowadays use transportation very frequently, and motorcycles are also very popular as a means of transportation. Motorcycles are usually two-wheeled or three-wheeled, but two-wheeled ones are the majority as a means of transportation. Motorcycles are easy to operate, easy to move, and inexpensive, so they are widely used in daily life, transportation, and public security, and are also widely used in developing countries. There are currently about 200 million motorcycles in the world, most of which are concentrated in Asia, accounting for about 58% of the world's motorcycles. There are many ways to classify motorcycles. The laws of various countries generally classify them by engine power and displacement, but motorcycle riders are more keen to classify them by motorcycle mechanical structure, appearance design, and actual use. Common types of mass-produced motorcycles include street cars, sports cars, and off-road vehicles. A street bike (street bike, roadster) is a motorcycle suitable for daily riding, focusing on practicality and having high handlebars to make the riding posture more natural. The engine of a street bike is usually exposed, so Japanese motorcycle riders call street bikes naked bikes (abbreviated as NK), and the United States calls cheap and low-spec (usually below 400cc) motorcycles street bikes. Sport bikes (superbikes) are performance-oriented motorcycles with good acceleration, handling and cornering ability on the road, but the driving comfort is lower than that of street bikes.

Regardless of the type of motorcycle, it is usually not equipped with audio equipment. Even if some motorcycles are equipped with audio, they still remain in the field of traditional audio technology. Therefore, there is a need to redevelop a sound system that can adapt to the current needs of motorcycle sound effects and integrate flat sound and flat display, and this invention was born.

Based on the above, in one viewpoint of the present invention, one of the purposes of the present invention is to provide a two-wheeled or three-wheeled vehicle with a glass diaphragm speaker, wherein the two-wheeled or three-wheeled vehicle includes a motorcycle, a bicycle, whether it is a fuel or electric vehicle.

The present invention solves the deficiencies of the prior art and proposes a two-wheeled or three-wheeled vehicle with a glass diaphragm, which includes a power system mechanically connected to the front and rear wheels; a control device configured to control the power system; and a speaker electrically connected to the control device, wherein the speaker has a glass diaphragm; the glass diaphragm can be part of a display or be configured separately from the display.

In one aspect, the present invention includes a plurality of planar voice coils disposed on one side of a glass diaphragm; a magnet assembly is disposed correspondingly to the plurality of planar voice coils to facilitate vibration and sound generation. The planar voice coils are made of materials such as silver, indium tin oxide, indium zinc oxide, or indium gallium zinc oxide.

The two-wheeled vehicle package with a glass diaphragm of the present invention further includes a communication device, an electrically coupled control device for connecting with an external device; a microphone and a noise reduction device, which is electrically coupled to the control device for suppressing noise.

From another perspective, the glass diaphragm can be in the shape of a cone, a plane or a dome. In one embodiment, the flat area of the glass diaphragm has a three-dimensional structure, and the average distribution area of the three-dimensional structure accounts for more than 40%; the ridge of the three-dimensional structure is 1/2 or more of the thickness of the glass diaphragm.

The embodiments of the present invention applied to a two-wheeled vehicle with a glass diaphragm can also be applied to a three-wheeled vehicle. Therefore, in this embodiment, it is self-evident that the third wheel is mechanically connected to the power system.

In one embodiment, the present invention integrates a sound unit and a flat-panel display into a multimedia device, which includes a glass diaphragm having a first surface with a light-emitting array formed thereon; a plurality of planar voice coils are arranged on a second surface of the glass diaphragm opposite to the first surface, and a magnetic iron assembly is arranged below the plurality of planar voice coils.

The present invention will be described in detail with respect to specific embodiments of the invention and its viewpoints. Such description is to explain the structure or step flow of the present invention, which is for the purpose of explanation and not for limiting the present invention. Therefore, in addition to the specific embodiments and preferred embodiments in the specification, the present invention can also be widely implemented in other different embodiments. The following is an explanation of the implementation of the present invention by means of specific specific embodiments. People familiar with this technology can easily understand the effectiveness and advantages of the present invention through the contents disclosed in this specification. Moreover, the present invention can also be used and implemented through other specific embodiments. The various details described in this specification can also be applied and adjusted based on different needs, and various modifications or changes can be made without departing from the spirit of the present invention.

The present invention provides a two-wheeled or three-wheeled vehicle with a glass diaphragm speaker. The two-wheeled or three-wheeled vehicle includes a motorcycle, a bicycle, and a gasoline or electric vehicle. For the sake of explanation, the following description will be based on a two-wheeled vehicle, but this description is not intended to limit the present invention.

FIG. 1 shows a two-wheeled vehicle 10, which has a main body 12, in which a power system 14 is disposed, such as an engine or a motor, which mechanically transmits power to the front and rear wheels 16 through a transmission device (not shown). The two-wheeled vehicle 10 has a steering handle 18 to control the steering of the front wheel 16. A flat multimedia device 100 is disposed in the upper area of the steering handle 18. Traditionally, it simply displays information without any audio effect.

Glass diaphragms made of reinforced glass have many advantages, such as higher electrical/acoustic conversion efficiency due to the high mechanical strength, low density, and fast sound speed of glass; a larger frequency range due to its strong rigidity to reduce split vibration, small deformation at low frequencies, good sound quality/tone, and good processability. The display of the electronic device is made of glass, so the present invention proposes an integration technology that integrates the sound unit with the flat display and uses the glass of the flat display as the diaphragm. Of course, the present invention can also separate the display and the glass diaphragm speaker, which still falls under the concept of the present invention.

As shown in FIG. 2, a functional block diagram of the present invention, in this embodiment, the two-wheeled vehicle 10 includes a control device (or vehicle-mounted computer, driving computer) 20, which can control the output of the power system 14, thereby transmitting power to the front and rear wheels 16. The control device 20 and the flat multimedia device 100 can communicate and transmit signals electrically. The flat multimedia device 100 includes a processor 28, which is electrically connected to a noise reduction device 32 and a communication device 30, and a microphone 34 is electrically connected to the noise reduction device 32. The flat multimedia device 100 includes a storage medium 26, a display 24, and a glass diaphragm speaker 22, which is electrically connected to the processor 28. Please refer to the second figure, the noise reduction device 32 is a noise suppression device, which is used to suppress or eliminate noise generated by various noise sources. For example, the noise reduction device 32 can use a noise filter to reduce the noise source. The means can be to generate a signal that is inversely proportional to the noise waveform, and use the two to generate destructive interference to suppress or eliminate the decibel value (dB value) of the noise source to achieve the purpose of noise reduction. The microphone 34 is electrically coupled to the noise reduction device 32 to receive the noise generated by the noise source. Another method is that the present invention stores a noise waveform database, in which noise waveform graphs (noise patterns) of the noise source are stored. For example, the environmental noise is detected before broadcasting, and noise reduction is provided during broadcasting. The noise filter offsets the noise signal with the corresponding noise waveform graph signal and outputs it through the speaker. For example, the noise waveform graph database can also be stored in the storage medium 26.

In one embodiment, the user of the two-wheeled vehicle 10 can communicate with another communication device (e.g., a smartphone, tablet) through the communication device 30. For example, the communication device 30 can communicate through a wireless network, and the wireless network specifications can include wireless networks of various wireless specifications such as Bluetooth, WiFi, or 5G. In one embodiment, the application of the flat multimedia device 100 can be connected to an external device through the communication device 30 therein.

In addition, through the configuration described in the previous paragraph, the user downloads or streams audio and video through the communication device 30, and plays it on the display 24 and glass diaphragm speaker 22 of the flat multimedia device 100. In one embodiment, the display 24 of the flat multimedia device 100 has a touch panel, and the control panel can be configured on the display 24. The communication device can also be used to conduct audio and video calls with at least one user to facilitate remote sharing.

In one embodiment, the voice control device 29 is electrically connected to the processor 28, and the user uses the microphone 34 to intelligently control the operation functions, such as controlling the volume, selecting programs and music, etc. In one embodiment, the voice control device 29 includes a voice recognition module, a natural language processing module, a dialogue management module and an intention judgment module. The voice recognition module is used to perform voice recognition processing on the voice message to obtain a voice recognition message. The natural language processing module includes a semantic understanding module and a dialogue generation module. The semantic understanding module is used to perform semantic understanding processing on the speech recognition information to obtain corresponding semantic understanding information, and input the semantic understanding information into the dialogue management module to perform dialogue management processing to obtain corresponding dialogue management information. Thereafter, the dialogue management information is input into the intention judgment module to perform intention judgment processing to obtain corresponding intention judgment information.

In one embodiment, the storage medium 26 can store audio and video data or application software. The storage medium 26 includes, for example, a memory or a computer-readable medium. The memory stores software or programs that can be run by the processor. The memory includes non-permanent memory, random access memory (RAM) and/or non-volatile memory, such as read-only memory (ROM) or flash memory (Flash RAM). Storage media include, but are not limited to, phase change memory (PRAM), static random access memory (SRAM), dynamic random access memory (DRAM), other types of random access memory (RAM) or read-only memory (ROM), which can be used to store information that can be accessed by a computing device.

In one embodiment, as stated above, the present invention can communicate with an external device, which can be a smartphone, a tablet computer, a smart watch or other electronic device types. The external device includes a computing core, a user interface, an Internet interface, a wireless communication transceiver and a storage device. The user interface includes one or more input devices (e.g., a keyboard, a touch screen, a voice input device, etc.), one or more audio output devices (e.g., a speaker, etc.) and/or one or more visual output devices (e.g., a video graphics display, a touch screen, etc.). The Internet interface includes one or more networking devices (e.g., a wireless local area network (WLAN) device, a wired LAN device, a wireless wide area network (WWAN) device, etc.). The computing core includes a processor and other computing core components, and the other computing core components include a video graphics processing unit, a memory controller, a main memory (e.g., RAM), one or more input/output (I/O) device interface modules, an input/output (I/O) interface, an input/output (I/O) controller, a peripheral device interface, one or more USB interface modules, one or more network interface modules, one or more memory interface modules and/or one or more peripheral device interface modules.

In one embodiment, FIG. 3 shows a side view of a glass diaphragm speaker 22. As shown, a glass substrate is used as a vibrating body (glass diaphragm), that is, a glass diaphragm 220, and a planar voice coil 222 is made on the glass surface of the non-display/light-emitting side of the display by printing, coating or lithography, and a magnetic component 224 is set under the glass diaphragm to form a magnetic field. Under the action of the magnetic field, the glass diaphragm 220 drives the display panel to vibrate and emit sound. The planar voice coil 222 electrically connected to the sound source signal and the magnetic assembly 224 disposed below it can be used as an actuator or exciter to drive the display screen to vibrate and produce sound. The magnetic assembly 224 includes a plurality of magnetic units 224a. The current flowing inside the planar voice coil 222 is orthogonal to the magnetic field generated by the magnetic assembly 224. By flowing the alternating current in the planar voice coil 222, a force that complies with Faraday's law is generated. Under the action of the force, the integrated glass diaphragm 220 vibrates in the vertical direction, thereby generating sound.

In one embodiment, the planar voice coil 222 is a conductive circuit made of materials such as silver (Ag), indium tin oxide (ITO), indium zinc oxide (IZO), and indium gallium zinc oxide (IGZO). The display panel can be, for example, LCD, mini-LED, or OLED, but is not limited thereto. In addition to the magnetic direction configuration of the magnet as shown in the enlarged view of FIG. 3, the structure of the magnet assembly 224 can be a Halbach Array structure to enhance the magnetic field strength in the unit direction and generate the strongest magnetic field with the least amount of magnets. The array is made of rare earth permanent magnet materials. By arranging permanent magnets with different magnetic directions according to a certain pattern, the magnetic field at the top of the magnet is stronger, while the bottom is relatively weak. It can gather the magnetic lines of force on one side of the magnet and weaken the magnetic lines of force on the other side, thereby obtaining a more ideal unilateral magnetic field.

The display of the flat multimedia device 100 may adopt technical solutions such as liquid crystal, sub-millimeter light-emitting diodes or organic light-emitting diodes. The glass diaphragm speaker 22 uses the glass substrate of the display panel as a vibrating body (diaphragm), and a flat voice coil 222 is made on the glass surface of the non-display/light-emitting side of the display panel. A magnetic iron component 224 is set under the glass diaphragm 220 to form a magnetic field. The flat voice coil 222 can also be integrated into a flexible circuit board, so that the driver IC (driver circuit) and other components such as D/A converters, digital signal processors, sound signal outputs, and image signal outputs on the rigid circuit board are electrically connected to the display panel to provide it with sound signals, image signals, etc. Based on the above spirit of the present invention, the planar voice coil 222 of the present invention can also be manufactured to have a shape of concentric circles or a racetrack to adapt to different usage scenarios.

Since the sound is generated by the vibration of the diaphragm, an independently configured horn or loudspeaker can be provided in another embodiment. After the glass material is heated to the molding temperature, the upper and lower molds are used to press it into the desired three-dimensional shape. According to one embodiment of the present invention, the diaphragm is pressed into a conical, flat or dome-shaped diaphragm. The diaphragm made of reinforced glass has the following excellent characteristics: high electroacoustic conversion efficiency (due to its high mechanical strength, low density and fast sound speed), a large frequency range (due to its strong rigidity, which can reduce split vibration and small deformation at low frequencies), good sound quality/tone color, and good processing.

According to an embodiment of the present invention, a small-area three-dimensional structure is formed in a flat area of the glass diaphragm 220, and its three-dimensional structure is shown in FIG. 4. In the figure, a flat area similar to a conical diaphragm forms a plurality of small-area three-dimensional deformation structures 201a, 201b, 201c... along its azimuth direction (direction of the dotted arrow), such as a ripple structure. Such a glass diaphragm 220 structure can suppress the vibration of a large area into a local vibration of a small area, thereby reducing the amplitude and time of the resonance frequency.

According to an embodiment of the present invention, the above-mentioned three-dimensional deformable structures 201a, 201b, 201c are evenly distributed over an area of more than 40% of the area of the glass diaphragm 220. The bulge amplitude of the three-dimensional deformable structures 201a, 201b, 201c is 1/2 or more of the diaphragm thickness, and the Young's modulus of the material of the above-mentioned glass diaphragm 220 is more than 70GPa.

From another perspective, the glass diaphragm speaker 22 or the flat multimedia device 100 of the present invention is placed on a two-wheeled vehicle in an open space, and it may be disturbed by rain. Therefore, the outer shell structure of the glass diaphragm speaker 22 or the flat multimedia device 100 of the present invention has waterproof properties. In one embodiment, the outer shell of the glass diaphragm speaker 22 or the flat multimedia device 100 can be waterproofed, for example, with waterproof tape and sealing ring as a protective means. The cavity and the outside of the speaker are composed of a layer of filter and a surrounding circle of waterproof silicone. The pore size of the filter is smaller than the water molecule group, which can prevent water from entering. Compared with structural waterproofing, nano waterproofing can also be used. A waterproof film can be applied to the speaker or flat multimedia device 100. The main purpose is to use the very small gaps in the nano coating, so that moisture cannot penetrate and condenses into water droplets and rolls down or waits to evaporate. Using nano materials to apply on certain parts of the casing can achieve excellent waterproof performance.

The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention and its benefits are described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the above embodiments or replace some of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the claims of the present invention.
