MICRO-SPEAKER DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240323591 titled 'MICRO-SPEAKER DEVICE
Simplified Explanation:
The speaker device described in the patent application includes a housing with an acoustic aperture, a transducer element to generate sound, and a shutter element that can control the sound output. The controller sends signals to the transducer and shutter elements to produce audio with ultrasonic components.
- The speaker device has a housing with an acoustic aperture.
- It includes a transducer element to generate sound.
- A shutter element is present to control the sound output.
- The controller sends signals to the transducer and shutter elements.
- The audio produced has ultrasonic components modulated with an audio signal.
Potential Applications: This technology could be used in smart speakers, home audio systems, public address systems, and other audio devices where precise sound control is required.
Problems Solved: This technology addresses the need for more precise control over sound output in speaker devices, allowing for better audio quality and user experience.
Benefits: The benefits of this technology include improved sound quality, enhanced user experience, and the ability to modulate sound with ultrasonic components for various applications.
Commercial Applications: Title: Advanced Sound Control Technology for Speaker Devices This technology can be commercially applied in smart home devices, audio equipment for public spaces, conference systems, and entertainment venues to provide high-quality sound with precise control.
Prior Art: Prior art related to this technology may include patents or research on sound modulation, speaker design, and acoustic control systems in audio devices.
Frequently Updated Research: Researchers may be exploring new ways to optimize sound modulation in speaker devices, improve the efficiency of transducer elements, and enhance the overall performance of audio systems.
'Questions about Speaker Device Technology: 1. How does the ultrasonic signal component affect the audio quality in speaker devices? 2. What are the potential limitations of using a shutter element for sound control in speaker devices?
Original Abstract Submitted
a speaker device comprises a housing having an acoustic aperture, a transducer element in the housing configured to receive a first actuation signal and to generate an acoustic output signal. the speaker device comprises a shutter element in the housing configured to receive a second actuation signal and arranged laterally offset to the transducer in the housing. the shutter element is arranged in an acoustic path between the transducer element and the acoustic aperture and comprises a shutter portion movable in opposite directions in response to the second actuation signal. a controller provides the first actuation signal to the transducer element, while the first actuation signal has an ultrasonic signal component modulated with an audio signal component. the controller provides the second actuation signal to the shutter element that has half the frequency of the ultrasonic signal component.
