Description

Sound and light glass sound device

The present invention relates to a sound-generating device, in particular to an acousto-optic glass sound-generating device.

Generally speaking, a traditional acoustic system includes a closed box and a sound unit mounted on the closed box, and a chamber is formed between the closed box and the sound unit. Due to the volume limitation of the chamber in the acoustic system, it is difficult for the acoustic system, especially a small acoustic system, to achieve a satisfactory bass reproduction effect.

With the development of technology, sound units need to be installed in various electronic devices. In the existing technology, the sound unit is usually installed under the display panel. If a better sound effect is required, the sound unit will be larger and occupy a larger space. If the sound unit is too small, a good sound effect cannot be achieved. In addition, the sound unit is usually installed in the corner area of the display panel, so that the sound position is fixed and the user cannot get a good auditory experience.

Currently, electronic device displays have narrow bezels or even full-screen designs, leaving less and less space for sound devices. Traditional sound devices are large in size and their installation locations are limited. It is difficult to find a suitable location and space for installation in the new generation of display devices.

In addition, when space is limited, how to design a more efficient sound device and improve its low-frequency frequency response is a major challenge. To solve this problem, the present invention proposes a novel sound device.

Based on the above, the present invention proposes an acoustic-optic glass sound-generating device, which utilizes the characteristics of the glass diaphragm itself and integrates it on a printed circuit board to achieve the production of an acoustic-optic glass sound-generating device.

The sound-light glass sound-generating device of the present invention produces sound through a glass diaphragm and emits light through a light-emitting element, thereby achieving a sound-light performance effect.

In the present invention, the sound and light glass sound device can not only emit high-quality sound and light of various colors, but also includes functions such as photography, ambient light sensing, infrared sensing, and ultraviolet sensing.

According to one viewpoint of the present invention, an acousto-optic glass sound-generating device is proposed, comprising: a glass sound-generating device, including a glass diaphragm to facilitate sound generation; a light-emitting element, arranged behind the glass sound-generating device, to facilitate light generation through the glass sound-generating device.

According to one aspect of the present invention, the above-mentioned acousto-optic glass sound device further includes a processor coupled to the glass sound device and the light-emitting element; an infrared sensor coupled to the processor; a camera element coupled to the processor to facilitate photography; an ambient light sensor coupled to the processor; and an ultraviolet sensor coupled to the processor.

According to another aspect of the present invention, the above-mentioned sound-light glass sound-generating device further includes a communication component coupled to a processor; a volume controller coupled to a processor; and a lightness controller coupled to a processor.

According to another aspect of the present invention, the glass sound-generating device further includes a voice coil disposed on the surface of the glass diaphragm, and a magnetic assembly disposed below the glass diaphragm. The acousto-optic glass sound-generating device is an active speaker or a passive speaker.

Here, the present invention will be described in detail for specific embodiments and viewpoints of the invention. Such description is to explain the structure or step flow of the present invention, which is for illustrative purposes rather than to limit the scope of the patent application of 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 a specific embodiment to illustrate the implementation of the present invention. People familiar with this technology can easily understand the effectiveness and advantages of the present invention through the content disclosed in this specification. In addition, the present invention can also be used and implemented through other specific embodiments. The details described in this specification can also be applied based on different needs, and various modifications or changes can be made without deviating from the spirit of the present invention.

The glass diaphragm made of reinforced glass has the following excellent properties: high electroacoustic conversion efficiency (due to its high mechanical strength, low density, and fast sound speed), wide frequency range (due to its strong rigidity, which can reduce split vibration and small deformation at low frequencies), good sound quality/tone, and good processability. Therefore, integrating the glass diaphragm on the printed circuit board can achieve an acoustic and optical glass sound device.

The first figure shows a schematic diagram of an acousto-optic glass sound device. The acousto-optic glass sound device includes a glass sound device 100 and a printed circuit board 106. The glass sound device 100 is disposed on the printed circuit board 106. That is, the glass sound device 100 is integrated on the printed circuit board 106 to achieve an acousto-optic glass sound device. Various components or modules with application functions are disposed on the printed circuit board 106, such as various sensors, light-emitting components, camera components, etc., to achieve the effect of sound and light. In the present embodiment, the glass sound device 100 includes a glass diaphragm 102 and a voice coil 104, wherein the glass diaphragm 102 is in the shape of a groove, and the voice coil 104 is a planar voice coil. Of course, this is just an example, and glass diaphragms and voice coils of other shapes are also included in the scope of the present invention. The glass diaphragm 102 generates vibrations to produce sound, so that the glass sound-generating device 100 has the function of a speaker. For the sake of simplicity, the components of the speaker, such as the rubber skirt, frame, etc., are not shown in the figure.

The second figure shows a side view of a glass sound device of an embodiment of the present invention. As shown in the second figure, the glass sound device 200 includes a glass diaphragm 202, a voice coil 203 and a magnet assembly 204. In this embodiment, the glass diaphragm 202, the voice coil 203 and the magnet assembly 204 are taken as examples of planar shapes, and glass diaphragms, voice coils and magnet assemblies of other shapes are also included in the scope of the present invention. For example, the voice coil 203 can be manufactured on the glass surface of the glass diaphragm 202 using a coating process and a lithography process to form a planar voice coil 203. In addition, a magnet assembly 204 is provided under the glass diaphragm 202 to form a magnetic field. The glass diaphragm 202 is driven by the magnetic field to vibrate and emit sound. Among them, the planar voice coil 203 electrically connected to the sound source electrical signal combined with the magnetic iron assembly 204 arranged below it can be used as an actuator or exciter to drive the glass diaphragm 202 to generate vibration and produce sound.

In one embodiment, the planar voice coil 203 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), but is not limited thereto.

In one embodiment, the magnetic assembly 204 is a magnetic array, which is composed of a plurality of magnets. The individual magnetic units 204a of the magnetic array form a staggered arrangement of north poles (N) and south poles (S) near the voice coil 203, forming magnetic field lines 206 as shown in the figure, which show the corresponding magnetic field direction. Since the current direction of the voice coil 203 flows into or out of the paper, the magnetic field and the current will form a vertical force F. It can drive the glass diaphragm 202 to vibrate and produce sound.

FIG. 3 shows a functional block diagram of an acousto-optic glass sounding device of an embodiment of the present invention. In this embodiment, the acousto-optic glass sounding device 300 includes: a processor 302, a glass sounding device 303, a light-emitting element 304, a camera element 306, an infrared sensor 308, an ambient light sensor 310, an ultraviolet sensor 312, a communication component 314, a volume controller 316, a light controller 318, and a storage medium 320. The processor 302 is coupled to the glass sounding device 303, the light-emitting element 304, the camera element 306, the infrared sensor 308, the ambient light sensor 310, the ultraviolet sensor 312, the communication component 314, the volume controller 316, the light controller 318, and the storage medium 320 to control these components. The light-emitting element 304 is, for example, a light-emitting diode, which is used to generate light of various colors or white light. The light-emitting element 304 is arranged behind the glass sound-emitting device 303 to facilitate light emission through the glass sound-emitting device 303.

The acoustic and optical glass sound-generating device 300 can be an active speaker (Active Speaker) or a passive speaker (Passive Speaker). Active speakers need to be set up with crossover and amplification circuits, and can produce sound by simply connecting to a power source and inputting a music signal. Passive speakers do not have an amplification circuit and need to be driven by the output of a post-stage or amplifier to produce sound. Passive speakers are used to adjust the counterweight to extend the bass. The advantage of this application is that different speakers do not need to be made according to the size of the panel, which can reduce costs and provide extended bass. In one embodiment, the glass diaphragm can be used in conjunction with a rubber skirt and a metal frame to adjust the counterweight to extend the bass. For example, the passive speaker with glass diaphragm of the present invention includes a light array and its corresponding wiring. The image display of the light array is driven and controlled by an image driver IC. The image driver IC is electrically connected to the control circuit board through a plurality of through holes on the glass diaphragm and a flexible connection line.

In one embodiment, the user of the sound and light glass sound device 300 can communicate with another device (e.g., a smart phone, a tablet computer, a sound and light glass sound device) through the communication component 314. For example, the communication component 314 can communicate through a wireless network, including Bluetooth, WLAN, Wifi, 3G, 4G, 5G and other wireless networks of various wireless specifications.

In one embodiment, the volume of the sound played by the sound and light glass sound device 300 can be adjusted by the volume controller 316. For example, the environmental noise includes normal environmental noise, low environmental noise and high environmental noise, and the sound of the sound and light glass sound device 300 also corresponds to normal speaker sound, woofer sound and tweeter sound. For example, when the surrounding environment is in normal environmental noise, the volume controller 316 adjusts the sound of the sound-light glass sound device 300 to a normal speaker sound according to the normal environmental noise; when the surrounding environment is in low environmental noise, the volume controller 316 adjusts the sound of the sound-light glass sound device 300 to a bass speaker sound according to the low environmental noise; conversely, when the surrounding environment is in high environmental noise, the volume controller 316 adjusts the sound of the sound-light glass sound device 300 to a tweeter sound according to the high environmental noise.

In one embodiment, the brightness of the light emitted by the sound-light glass sound-emitting device 300 can be adjusted by the light intensity controller 318. For example, the ambient light sensed by the ambient light sensor 310 is divided into three levels, normal brightness, low brightness and high brightness, and the light brightness of the sound-light glass sound-emitting device 300 also corresponds to normal brightness, low brightness and high brightness. For example, when the ambient environment is at normal ambient light brightness, the light controller 318 adjusts the sound-light glass sound device 300 to emit normal light brightness according to the normal ambient light brightness; when the ambient environment is at low ambient light brightness, the light controller 318 adjusts the sound-light glass sound device 300 to emit high light brightness according to the low ambient light brightness to increase the brightness of the environment; conversely, when the ambient environment is at high ambient light brightness, the sound-light glass sound device 300 may not emit light.

In one embodiment, the sound and light glass sound device 300 includes an infrared sensor 308. The infrared sensor 308 can continuously sense the body temperature of the organism and generate multiple body temperature sensing signals. The infrared sensor 308 is used to measure the body temperature without contacting the organism. When the body temperature detection value of the sound and light glass sound device 300 is greater than the high temperature preset value or lower than the low temperature preset value, a warning message can be sent to an external electronic device to learn the body condition of the detected person from the external electronic device. When the sound and light glass sound device 300 determines that the body temperature detection value is higher or lower than the preset value, a warning message can be sent to the external electronic device, or a warning sound can be emitted through the glass sound device 303. That is, the present invention has the function of an infrared human body temperature reminder speaker.

In one embodiment, the sound and light glass sound device 300 includes an ultraviolet sensor 312. The ultraviolet sensor 312 can sense the ultraviolet intensity of the environment. When the ultraviolet detection value of the environment sensed by the ultraviolet sensor 312 of the sound and light glass sound device 300 is greater than a preset value, a warning message can be transmitted to an external electronic device, or a warning sound can be emitted through the glass sound device 303. That is, the present invention has the function of a high ultraviolet intensity reminder speaker. In addition, through the camera element 306, the sound and light glass sound device 300 also has a camera function. For example, when the glass sound device 303 emits a sound, the camera element 306 can capture an image to record the sound and image information to form audio and video data and store it in the storage medium 320. The video files stored in the storage medium 320 can be played back in other devices.

In one embodiment, the storage medium 320 can store music data, other audio data or application software. The storage medium 320 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, the acousto-optic glass sound device 300 is configured to communicate with an external device, which may be an external computing device, a computing system, a mobile device (smartphone, tablet computer, smart watch, etc.), or other electronic device types.

External devices include computing cores, user interfaces, Internet interfaces, wireless communication transceivers, and storage devices. The user interface includes one or more input devices (e.g., keyboards, touch screens, voice input devices, etc.), one or more audio output devices (e.g., speakers, etc.) and/or one or more visual output devices (e.g., video graphics display, touch screen, etc.). The Internet interface includes one or more networking devices (e.g., wireless local area network (WLAN) devices, wired LAN devices, wireless wide area network (WWAN) devices, etc.). Storage devices include flash memory devices, one or more hard disk drives, one or more solid-state storage devices, and/or cloud storage.

The computing core includes a processor and other computing core components. 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.

The external device processes the data sent by the communication component 314 to produce various results.

From the above, it can be seen that the present invention provides an acoustic and optical glass sound device, which, in addition to being able to produce high-quality sound, also includes functions such as lighting, photography, ambient light sensing, infrared sensing, and ultraviolet sensing.
