  • Patent number: 10834510
    Abstract: Systems and methods for hearing devices with proactive power management are provided. Various embodiments dynamically adapt power consumption to the preferences, needs, and behavior of the hearing device user such that the hearing device provides function until the hearing device can be recharged. Moreover, some embodiments exploit the trend of more intelligent devices and machine learning to create dynamic power management schedules which can be temporarily implemented to create an optimal blend of performance versus battery life while minimizing perception of the feature or performance reduction to the user. Moreover, the dynamic nature of the power management used in various embodiments can account for battery degradation, updated firmware, and/or other factors that may impact battery life as the hearing device ages.

  • Patent number: 10750264
    Abstract: The present utility model relates to a loudspeaker, in particular to a loudspeaker and a loudspeaker shock absorption structure, which comprise a first elastomer for connecting with a loudspeaker body and a second elastomer for connecting with a loudspeaker fastener structure, the first elastomer and the second elastomer are connected by a cantilever, the cantilever is made of an elastic material. The present utility model forms a non-coaxial connection structure between the loudspeaker body and the loudspeaker fastener structure by setting a cantilever, so that a force produced by a vibration of the loudspeaker body cannot be directly transmitted to the loudspeaker fastener structure. Instead, the force is acted on the fastener structure in the form of a small force after being weakened by buffering and filtering via the cantilever, thereby greatly reducing a machine vibration caused by a large amplitude of the loudspeaker.
