Description

Technical Field

[0001] This utility model relates to the field of television technology, and in particular to a voice-controlled television. Background Technology

[0002] With the development of intelligent voice technology, more and more smart devices are beginning to support intelligent voice control. Intelligent voice control technology has been gradually applied to televisions, allowing users to control the television with their voice through the voice recognition device configured on the television. This has brought about a new revolution in television control technology.

[0003] However, existing technologies typically use a microphone to capture the user's voice, then process the voice signal and transmit it to the TV's mainboard. The TV's mainboard then generates corresponding actions based on the voice signal (such as changing the operating mode, changing the channel, and adjusting the volume). This type of voice input control is prone to failure to detect the user's voice or misrecognize the voice when there is a lot of external noise, noisy human voices, or the user is far away from the TV. As a result, the user cannot control the TV by voice, which affects the user experience. Utility Model Content

[0023] like Figure 1As shown, the voice-controlled television of this embodiment includes a television body and a control circuit disposed within the television body. The control circuit includes: multiple voice acquisition modules 1, which are used to acquire voice signals and convert the voice signals into electrical signals; a voice signal processing module 2, which is electrically connected to all the voice acquisition modules 1 and is used to process the multiple electrical signals into voice control signals; and a television motherboard 3, which is electrically connected to the voice signal processing module 2 and controls the television body to perform corresponding actions according to the voice control signals.

[0024] In this embodiment, the voice acquisition module 1 acquires the user's voice signal through a microphone (MIC) and converts the voice signal into an electrical signal, which is then transmitted to the voice signal processing module 2. Since the volume of the sound acquired by the voice acquisition module 1 at different locations varies and the interference is different, the voice signal processing module 2 compares and processes the multiple electrical signals to eliminate interference signals. Then, the compared signal is compared and identified with a pre-trained voice model preset by the voice signal processing module 2. Based on the obtained recognition and comparison results, a voice control signal is sent to the TV mainboard 3. The TV mainboard 3 executes corresponding actions according to the voice control signal, such as changing the TV's working mode (standby / start), changing the channel, and adjusting the volume. In this embodiment, the voice-controlled TV can use multiple voice signals through the multi-channel voice acquisition module 1, which can more clearly and accurately acquire the user's voice, making the voice control of the TV more accurate and providing a better user experience.

[0025] It should be noted that, in this embodiment, since the television only performs a few actions such as changing the working mode, changing the channel, and adjusting the volume, the voice signals of these few actions can be pre-trained and stored in the voice signal processing module 2. The voice signal processing module 2 will filter and fuse the electrical signal obtained from the voice acquisition module 1, and then directly compare it with the pre-stored voice model in the voice signal processing module 2 to determine the command corresponding to the user's voice. The voice signal processing module 2 will then generate a voice control signal from the comparison result and send it to the television motherboard, thereby controlling the television motherboard to perform the corresponding action and realizing the voice control function of the television.

[0026] In some embodiments, such as Figure 2 As shown, the voice acquisition module 1 includes a microphone 11 for acquiring voice signals, an operational amplifier 12 for amplifying voice signals, a filtering module 13 for filtering voice signals, and an analog-to-digital converter module 14 for converting voice signals into digital electrical signals. The microphone 11, operational amplifier 12, filtering module 13, and analog-to-digital converter module 14 are connected in sequence.

[0027] The microphone 11 collects the user's voice signal and converts the sound wave vibration into an electrical signal. The collected voice command signal is first amplified by the operational amplifier 12, and then filtered by the filtering module 13 to remove high-frequency interference signals before being sent to the analog-to-digital converter 14. In this embodiment, the filtering module 13 specifically adopts an anti-aliasing filter. The analog-to-digital converter 14 converts the collected analog voice signal into a digital electrical signal for use by the voice signal processing module 2.

[0028] In some embodiments, the voice signal processing module 2 includes a voice control chip 21, a DC-DC power supply module 22, an interface module 23, and a memory 24, all of which are electrically connected to the voice control chip 21.

[0029] Among them, the DC-DC power module 22 is used to convert the input voltage into the working voltage required for the voice control chip 21 to work, the interface module 23 is used to electrically connect the voice control chip 21 with the voice acquisition module 1, the TV motherboard 3 and other modules, and the storage 24 is used to store system data.

[0030] In some embodiments, the interface module 23 includes a GPIO interface module 231, a UART communication interface module 232, and a USB interface module 233, all of which are electrically connected to the voice control chip 21.

[0031] Among them, the GPIO interface module 231 and the UART communication interface module 232 can be used as expansion interfaces to connect with internal and external modules. For example, remote wireless control function can be realized by connecting WiFi / Bluetooth module. The USB interface module 233 connects to the TV motherboard 1 to realize signal transmission between the TV motherboard 1 and the voice control chip 21.

[0032] In some embodiments, the memory 24 is a flash memory, and the flash memory communicates with the voice control chip 21 via the SPI communication protocol.

[0033] Specifically, the flash memory and the voice control chip 21 communicate through the XIP module of SPI communication. SPI communication is a high-speed, full-duplex, synchronous serial communication protocol. Its XIP module allows the voice control chip 21 to execute code directly from the external flash memory. The flash memory can expand the storage space of the voice control chip 21, enabling the voice control chip 21 to execute more complex programs.

[0034] In some embodiments, multiple voice acquisition modules 1 are arrayed within the main body of the television set. This array distribution allows for more comprehensive detection of the user's voice signals.

[0035] In some embodiments, there are 6 voice acquisition modules 1, 3 of which are located on the upper edge of the main body of the television, and the other 3 are symmetrically located on the lower edge of the main body of the television.

[0036] It is understandable that the edge of the TV body is the position closest to the user. By placing the voice acquisition module 1 on the top and bottom edges of the TV body, the user's voice information can be collected more clearly, and the six voice acquisition modules 1 can collect voice signals more accurately.

[0037] In some embodiments, the voice control chip 21 integrates multiple ADC modules, and the multiple voice acquisition modules 1 are respectively connected to the multiple ADC modules of the voice control chip.

[0038] Specifically, the voice control chip 21 also integrates a DSP processor and an SDAR. The SDAR can be used to store preset voice models. In other embodiments, the voice models can also be stored in flash memory. The voice control chip 21 in this embodiment integrates at least 6 ADC modules. Each voice acquisition module 1 is connected to an ADC module. The voice signal acquired by the voice acquisition module 1 is converted into an electrical signal and then input to the voice control chip 21 through the ADC module.

[0039] In some embodiments, the voice control chip is a GX8008C chip.

[0040] Specifically, the GX8008C voice chip is a low-cost, low-power single-chip voice processing chip with high integration, low power consumption, and high voice data processing capabilities. The GX8008C voice chip integrates a 32-bit RISC CPU with a frequency of 150MHz and a HIF4 DSP processor with a speed up to 400MHz, capable of processing large volumes of voice data. It also features 1.5MB of built-in SRAM to improve voice processing speed while reducing the number of external interfaces, and multiple ADC modules to enhance multi-angle voice input capabilities. The GX8008C voice chip operates on a 3.3V power supply, maximizing its ability to meet customers' low-power requirements.

[0041] The stator core provided in the above embodiments of this application has at least the following characteristics:

[0042] 1. The voice-controlled television in this embodiment collects user voice through multiple voice acquisition modules 1 to achieve multi-angle voice input, thereby more accurately collecting voice signals.

[0043] 2. After eliminating interference from multiple voice signals, the voice signal processing module 2 compares them with the preset voice model for recognition. Then, based on the recognition and comparison results, it sends a voice control signal to the TV motherboard 3. The TV motherboard 3 executes the corresponding action according to the voice control signal, thereby realizing voice control of the TV.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
