Embodiments of the present application are set forth in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
It will be understood that, as used herein, the terms "first," "second," and the like may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another.
Spatial relational terms, such as "under," "below," "under," "over," and the like may be used herein to describe one element or feature's relationship to another element or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements or features described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary terms "under" and "under" can encompass both an orientation of above and below. In addition, the device may also include additional orientations (e.g., rotated 90 degrees or other orientations) and the spatial descriptors used herein interpreted accordingly.
It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or be connected to the other element through intervening elements. Further, "connection" in the following embodiments is understood to mean "electrical connection", "communication connection", or the like, if there is a transfer of electrical signals or data between the connected objects.
As used herein, the singular forms "a", "an" and "the" may include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises/comprising," "includes" or "including," etc., specify the presence of stated features, integers, steps, operations, components, parts, or combinations thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof. Also, as used in this specification, the term "and/or" includes any and all combinations of the associated listed items.
The traditional scheme depends on an algorithm for setting the residual battery capacity in the TWS Bluetooth headset and sends the residual battery capacity to the smart phone end in a Bluetooth connection mode, so that the smart phone displays the residual battery capacity of the TWS Bluetooth headset; or, through the built-in vibrations warning or audible alarm of TWS bluetooth headset, the user is urged to reset TWS bluetooth headset in the box that charges. However, in practical applications, sound and vibration of the TWS bluetooth headset cannot attract the attention of users in most cases.
That is, in view of the usage habits of some bluetooth headset users, the conventional scheme has at least the following problems: some users forget to place the TWS Bluetooth headset in the charging box after using the TWS Bluetooth headset, but place the TWS Bluetooth headset on a table top or a bed surface, and the mobile phone is disconnected with the TWS Bluetooth headset, so that the TWS Bluetooth headset continuously works and discharges until power is lost.
When a user takes off the TWS Bluetooth headset, the traditional technology cannot give the user the most direct and effective visual impact on the residual electric quantity. The user does not deliberately look over the residual electric quantity of the TWS Bluetooth headset in the mobile phone after taking off the headset; after seeing the TWS bluetooth headset of placing alone on desktop or bed surface, the user can't learn the earphone electric quantity state, and then place it and charge and preserve in charging the box.
