Speech-Controlled Vanity Mirror with Audio Interference Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional vanity mirrors have a single function, which cannot meet the diverse needs of modern users, requiring a multifunctional solution for convenient operation and enhanced user experience.
Innovation Solution
A speech-controlled vanity mirror is designed with a vanity mirror body, two microphones, and a speech recognition control device, including a music control device and a speech control device, allowing users to control multifunctional devices such as a Bluetooth speaker, light source, camera, and mirror cleaner through voice instructions, while filtering audio signals to eliminate interference from loudspeaker noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-function vanity mirror is used, then the device complexity is low, but the adaptability and user needs coverage are insufficient
Solution Approach 1:
The vanity mirror integrates multiple functions including speech recognition control, music playback, lighting control, and appearance management into a single device. The control system can receive speech instructions to perform diverse operations such as playing music, adjusting lights, and controlling mirror functions, making the device universally applicable for various user needs during makeup and grooming activities
2Ease of operation
If speech control is added to the vanity mirror, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent replaces traditional mechanical control methods (buttons, switches) with speech recognition technology. The microphone captures speech signals, which are processed by the control system to execute corresponding functions. This substitution allows hands-free operation, improving ease of use especially when users have their hands occupied with makeup items or when hygiene is a concern
3Adaptability or versatility
If music playback is enabled in the vanity mirror, then the user experience is enhanced, but the speech recognition accuracy deteriorates due to audio interference
Solution Approach 1:
The patent introduces an intermediary processing mechanism where the control system distinguishes between music audio signals and speech instruction signals. When a speech instruction is detected, the system temporarily suspends or mutes the music playback, allowing clear speech recognition. After processing the speech command, the music playback is resumed. This intermediary control mechanism resolves the conflict between music enjoyment and accurate speech recognition
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The speech-control mode enhances user convenience, reduces operation time, and improves user experience by allowing hands-free control and accurate recognition of voice commands, even when music is playing, thereby meeting various user demands and reducing the risk of misoperation.
Implementation Method 1
a filter in the music control device filters the audio signal to eliminate interference of audio played by the loudspeaker in speech instructions of an user
Implementation Method 2
the second microphone acquires and transmits the speech instructions of the user to the speech control device

AI summary
A speech-controlled vanity mirror is provided, which includes a vanity mirror body, a first microphone, a second microphone and a speech recognition control device provided on the vanity mirror body. The speech recognition control device includes a music control device and a speech control device. The first microphone is connected to the music control device, and transmits the audio signal acquired from a loudspeaker to the music control device. A filter in the music control device filters the audio signal to eliminate the interference of the audio played by the loudspeaker in speech instructions of the user. The second microphone is connected to the speech control device, and transmits the speech instructions of the user to the speech control device. The speech control device adjusts and controls a multifunctional device on the vanity mirror body according to the speech instructions. It is convenient for users to operate, and the recognition rate and accuracy of the speech instruction are high.
