Description

Technical Field

[0001] This utility model relates to a speaker system, specifically a bulb-type speaker system that transmits multiple signals via WiFi. Background Technology

[0002] In the field of audio playback, as people's demands for sound quality and user experience continue to increase, the limitations of traditional audio playback devices are becoming increasingly apparent.

[0003] In terms of signal transmission, traditional speakers mostly use wired connections. This not only limits the placement of the speakers, making the installation layout inflexible, but also the complex cables can easily cause spatial clutter. Furthermore, cable damage can lead to unstable or even interrupted signal transmission. Even when some devices use wireless transmission, they are often susceptible to interference in complex electromagnetic environments due to their limited frequency band, making it impossible to guarantee stable audio signal transmission.

[0004] In terms of sound quality optimization, most speakers struggle to adapt to different acoustic environments. Factors such as room size, decoration materials, and furniture placement can lead to varying sound wave reflections. Traditional speakers lack intelligent acoustic analysis and optimization mechanisms, making it impossible for them to automatically adjust audio parameters to address these differences. This makes it difficult for users to achieve ideal sound quality in different environments.

[0005] From an installation and compatibility perspective, traditional speakers have relatively fixed shapes and installation methods, making it difficult to integrate with diverse interior design styles. Especially in places where space utilization is crucial, such as family living rooms and commercial exhibition spaces, traditional speakers occupy floor or table space, not only affecting aesthetics but also limiting the effective use of space.

[0049] (a) Transmission System (TX)

[0050] Audio input module: Supports three input methods: HDMI, Bluetooth 5.3, and optical input. The HDMI interface can connect to devices such as TVs and computers to transmit high-definition audio and video signals; Bluetooth 5.3 supports fast and stable connection to mobile devices such as mobile phones and tablets; the optical input is suitable for devices with high sound quality requirements, such as CD players, to ensure lossless transmission of audio signals.

[0051] Analog-to-digital converter (DAC): When an analog audio signal is input, this module can convert it into a digital signal so that subsequent modules can process it, ensuring accurate transmission and processing of the audio signal.

[0052] AI algorithm processing module: Built-in room adaptive algorithm, which generates accurate frequency response curves by detecting reflected sound waves in the room. Based on this curve, the system can dynamically adjust the equalization parameters of each channel, automatically analyze the current acoustic environment, optimize frequency matching, and ensure the best sound quality in different spaces.

[0053] MCU Control Unit: Integrates a high-efficiency audio compression algorithm to perform frequency division processing on digital signals, including left / right channel separation and bass channel extraction. Through precise frequency division, it achieves reasonable allocation of audio signals, laying the foundation for subsequent high-quality playback.

[0055] (ii) Receiving System (RX)

[0056] The receiving system consists of multiple bulb-type speakers, each with the following functional modules:

[0057] Wireless receiver module: accurately receives wireless signals from the transmitting system, ensuring signal integrity and stability, and providing a prerequisite for high-quality audio playback.

[0058] Digital-to-analog converter (DAC): Converts the received digital signal back into analog audio, enabling the audio signal to be processed and played by subsequent modules.

[0059] Audio amplification module: amplifies analog audio to drive the speaker and ensure that the sound is played clearly and loudly.

[0060] Light bulb-shaped housing: Featuring a cylindrical or hemispherical structure, it boasts a stylish appearance. The bottom is equipped with a threaded interface or snap-on mounting hardware, perfectly matching pre-drilled holes in the ceiling for convenient recessed installation, saving space and enhancing the aesthetics of the room.

[0061] High-fidelity speaker units: Each speaker has at least one full-range speaker unit and one tweeter unit, with a sound pressure level of ≥90dB. It supports multi-channel independent sound production, presenting rich sound details and bringing an immersive listening experience.

[0062] Working principle: When this utility model is used, the working process is mainly divided into two stages: signal transmission and signal reception. Through the coordinated operation of multiple functional modules, high-quality audio wireless transmission and playback can be achieved.

[0063] During the signal transmission phase, the audio input module first receives audio signals from different devices. When digital signal sources such as HDMI or optical fiber are connected, the signal can directly enter the subsequent processing flow; if Bluetooth devices or other analog signal sources are connected, the analog-to-digital converter (DAC) module will convert the analog audio signal into a digital signal. The converted digital signal then enters the AI ​​algorithm processing module, which generates a frequency response curve by detecting reflected sound waves in the room, and then dynamically adjusts the equalization parameters of each channel to achieve adaptive optimization of the acoustic environment, ensuring that the audio signal reaches the optimal frequency matching state in the current environment.

[0064] The acoustically optimized digital signal enters the MCU control unit, which uses an integrated audio compression algorithm to perform frequency division processing on the digital signal, separating it into independent signals such as the left channel, right channel, and bass channel. The frequency-divided signal is then transmitted by the wireless transmission module using a dual-band 5.2G / 5.8G frequency range. The wireless transmission module automatically switches between the two bands based on the ambient signal strength to ensure stable and efficient signal transmission.

[0065] During the signal reception phase, the bulb-shaped speaker in the receiving system captures the wireless signal emitted by the transmitting system through its built-in wireless receiver module. The received digital signal is transmitted to the digital-to-analog converter (DAC), which converts the digital signal back into an analog audio signal. Subsequently, the analog audio signal enters the audio amplification module, where it is amplified and then drives the high-fidelity speaker unit to produce sound. The full-range speaker unit and tweeter in each bulb-shaped speaker work together to achieve multi-channel independent sound, thus presenting users with a rich, detailed, and high-quality audio effect. At the same time, the unique housing design of the bulb-shaped speaker allows it to be installed in a ceiling recess, transmitting audio to every corner of the room without taking up extra space, meeting the audio playback needs of different scenarios.

[0066] Beneficial effects: Superior audio quality: The AI ​​algorithm processing module generates a frequency response curve by detecting reflected sound waves in the room and dynamically adjusts the equalization parameters of each channel to achieve adaptive optimization to the acoustic environment; the MCU control unit performs precise frequency division processing, combined with at least one built-in full-range speaker unit and tweeter unit, and a high-fidelity speaker with a sound pressure level ≥90dB, supporting multi-channel independent sound output, presenting rich sound details, and bringing an immersive listening experience.

[0067] Stable and efficient transmission: The wireless transmission module adopts 5.2G / 5.8G dual-band adaptive switching technology, which can automatically select the optimal frequency band according to the ambient signal strength, effectively avoid interference, ensure stable and fast transmission of audio signals, and guarantee smooth playback without lag.

[0068] Easy to install and use: The bulb-shaped speaker shell is designed in a cylindrical or hemispherical shape, with a threaded interface or snap-on mounting hardware at the bottom, making it suitable for ceiling-mounted installation. Installation is simple and saves space. The transmitting system supports multiple input methods such as HDMI, Bluetooth 5.3 and optical fiber to meet the connection needs of different devices and is easy to operate.
