The list published by the United States Trademark and Patent Office (USPTO) shows that Apple has recently obtained a new patent titled "Measuring a virtual listening environment." It is reported that this technology can improve the user's listening experience and enhance the immersion of spatial audio, and it is expected to be applied to AirPods in the future.
This patented technology adjusts the audio output by determining the user's virtual listening environment; users may listen to audio or watch video content in different scenarios, such as an empty outdoor, concert hall, living room, classroom or public On vehicles; it will help Apple provide a more intelligent audio output solution to bring users a more comfortable and natural listening experience.
Microphones can perceive sound by converting sound pressure changes into electrical signals through electroacoustic transducers. The electrical signal can be digitized by an analog-to-digital converter (ADC), and the audio can be rendered for playback using spatial filters, allowing the audio to be perceived as having a spatial quality. Spatial filters can artificially impart spatial cues into audio, similar to the diffraction, delay, and reflections naturally caused by body geometry and pinnae. The spatially filtered audio may be produced by a spatial audio reproduction system and output through headphones.
Nowadays, more and more earphone manufacturers pay attention to the function of anti-lost. Since Apple released AirTag, everyone has paid more attention to the anti-lost of items. Apple’s Find My can find iPhone, Mac, AirPods, and Apple Watch. Today’s Find My is no longer Only Apple devices can be found, and with the addition of third-party devices, the territory of Find My Network will be enriched. TWS earphones and Find My can realize the function of intelligent anti-lost.
Features supported by Find My
Harmful Tracking Detection: This feature notifies users of accessories that may not be recognized normally, and tracks the location of such accessories over time.
Lost mode setting number: Support setting specific devices or accessories into lost mode through this network, and you can also set a reserved number for people to contact you when they are found.
Find the location of the lost device: When a user loses a device, it can be marked as lost mode, and then the device information will be transmitted to each other in the Bluetooth network. Finally, when a user's Bluetooth detects the lost item, it will transmit its approximate location back to the original lost user to help the user find the device quickly.
Control the device to play sound: You can remotely initiate the play of sound to help users find accessories. This action supports both accessory owners and non-owners. After finding the approximate location of the accessory, the user can make the owner's iOS device sound a reminder, and the owner cancels the reminder to find the device.
In the future, Find My will become an independent network, and the addition of third-party devices will enrich the territory of Find My Network. Find My Network will provide third-party interfaces to provide better services. It will not destroy user privacy, except for the user, Apple and third parties will not know the specific location of the mobile phone. Apple's Find My technology uses Apple devices' Bluetooth wireless signals to create a device network to find lost items, and they will work with third-party companies to create Find My Network anti-lost products.
