Description

Technical Field

[0001] This invention relates to a karaoke system, belonging to the field of Internet of Things (IoT) technology. Background Technology

[0002] With the increasing demand for audio entertainment, existing karaoke methods have significant limitations: 1) KTV venues are fixed, expensive, and require multiple people to go together, which cannot meet the demand for instant karaoke; 2) Although small self-service karaoke rooms are relatively flexible, they are still limited by space and cannot achieve remote interaction; 3) When singing karaoke at home, the sound can easily spread through walls, doors and windows, disturbing the rest of neighbors, and users cannot sing loudly due to concerns; 4) When individuals want to sing karaoke outdoors or in public areas such as during commutes, there is a lack of private space, and the sound can easily cause discomfort to others; 5) When relatives and friends in different places want to sing karaoke together, existing tools can only achieve asynchronous recording and synthesis, which cannot achieve a real-time interactive duet experience; 6) When beginners practice singing, they are shy about singing in front of others and lack convenient private practice scenarios. While existing technologies include ordinary headphone microphone combinations or simple noise reduction devices, ordinary headphones cannot effectively reduce noise (singing will still leak out), and simple noise reduction devices are bulky and inconvenient to carry. Furthermore, none of them are integrated with an IoT platform to achieve remote real-time interactive functionality, thus failing to address the aforementioned multi-dimensional pain points. Summary of the Invention

[0003] The purpose of this invention is to provide a portable Internet of Things (IoT) karaoke system that enables private karaoke anytime, anywhere and real-time duets between relatives and friends in different locations, while also taking into account ease of operation and comfort of use.

[0004] To achieve the above objectives, the technical means adopted by the present invention is as follows: a karaoke system, comprising an IoT karaoke platform with an APP or mini-program and several noise-canceling karaoke headband components. The IoT karaoke platform and the noise-canceling karaoke headband components interact wirelessly. The noise-canceling karaoke headband components have noise-canceling parts, which consist of a mouth and nose noise-canceling chamber, a liquid-filled neck sleeve, an ear ring liquid-filled bladder, a one-way air intake valve, and a noise-canceling exhaust valve. The mouth and nose noise-canceling chamber has a semi-enclosed structure, and an ear ring is provided at the rear of the noise-canceling chamber. An ear ring liquid-filled bladder is provided inside the ear ring. The liquid-filled neck sleeve is fixedly connected to the lower part of the mouth and nose noise-canceling chamber. The one-way air intake valve and the noise-canceling exhaust valve are installed on the mouth and nose noise-canceling chamber. The anechoic chamber for the mouth and nose has a semi-enclosed structure, consisting of a double-layered hollow plastic shell and a silicone sealing strip. A vacuum is applied between the two shells (vacuum degree ≤10Pa) to block sound transmission. The silicone sealing strip is made of medical-grade soft silicone, ensuring a close fit around the user's mouth and nose and / or face without pressure marks or discomfort, with a sealing gap ≤0.1mm. The liquid-filled neck sleeve is fixedly connected to the lower part of the anechoic chamber for the mouth and nose. It is made of hollow elastic material and filled with a non-toxic and odorless damping fluid (such as silicone oil). The neck sleeve fits tightly against the user's neck, forming a closed acoustic space. The ear loop liquid bladder is connected to an adjuster, allowing the user to adjust the filling volume according to their head circumference. By blocking airborne sound transmission through the vacuum chamber and absorbing sound wave vibrations with the damping fluid, external noise reduction of ≥35dB is achieved.

[0005] Furthermore, the noise-canceling karaoke headband is an integrated portable wearable device with an overall weight controlled between 300 and 500g, making it convenient for prolonged wear. Its structure includes: The main body of the headband is made of lightweight PPS material and has sound-absorbing cotton inside.

[0006] The IoT karaoke platform supports both APP and WeChat mini-program formats, and its functions include: Basic karaoke functions: Built-in library of millions of songs, supports original / accompaniment switching, pitch adjustment, reverb effect selection, and synchronized lyrics display; Virtual interactive scenes: There are two main scenes: a virtual karaoke bar and a virtual karaoke plaza; Virtual KTV: Supports 2 to 8 people to create private rooms. Users can invite friends from the platform to join through voice commands or display components. The room supports real-time voice interaction, duet scoring, and synchronized lyrics scrolling. Virtual Karaoke Square: A public and interactive space where users can randomly match with strangers to sing duets or post their own performances for others to like and comment on. Interactive features: Supports voice control and text input; adding friends supports three methods: phone number search, QR code scanning, and platform recommendation. The specific steps for using the karaoke system are as follows: Users wear a portable, noise-canceling karaoke headset and log in to the IoT karaoke platform via a display device or mobile app; Select the usage scenario. If you choose a virtual karaoke bar, you can invite friends by voice or by entering a friend's ID to invite them to join. After a song is requested, the platform transmits the lyrics and backing track audio to the headband via the communication module. The headphones play the backing track, and the microphone captures the user's singing voice and transmits it back to the platform in real time. The singing voices of friends in different locations are transmitted in real time to their respective head-mounted components through the platform, enabling synchronized duets. The display components simultaneously show the friend's avatar, duet progress, lyrics, and rating information. The sound-absorbing components work together with a vacuum chamber and damping liquid to prevent the user's singing from leaking out, ensuring a private singing experience. After the performance, the platform automatically generates a performance score and audio file, which can be saved, shared to social media platforms, or used for a re-performance.

[0007] Furthermore: the aforementioned noise-canceling karaoke headset features an ambient sound mode, which users can activate via voice command, at which point the system automatically lowers the headphone volume; the microphone is equipped with an anti-feedback function, with a built-in audio feedback suppression algorithm to prevent feedback caused by secondary acquisition of the accompaniment sound played through the headphones; the platform supports recording and saving chorus recordings, automatically synthesizing the singing voices of all participants to generate a complete chorus audio, which can be downloaded and saved by each participant; the display component has adjustable brightness (3 levels) to adapt to strong outdoor light and low indoor light scenarios, and supports screen-off operation (voice control wake-up).

[0008] The beneficial technical effects of this invention are: Portability: The integrated headband design is small and lightweight, making it easy to carry around and breaking the limitations of location, enabling karaoke in any scenario such as outdoors, commuting, or at home; Privacy: The sound-absorbing components use a combination of vacuum and damping liquid for double sound absorption, resulting in significant noise reduction.
