Installation fixed form of the beads governor circuit 100 in shell 21 can be various mechanical means, such as spiral shell The formula of connecing is fixed, plug-in is fixed or the fixed form of other forms, as long as can effectively be fixed on beads governor circuit 100 In shell 21, it is ensured that accelerometer 12 can steadily and reliably work.Using the thought of above-mentioned beads governor circuit 100 Pearl can be no different in appearance with traditional beads of non-electrical minor.

Above-mentioned beads 200, it is nearest by using high performance accelerometer 12 on the market, master control module 14 and application The wireless charging technology to appear on the market, i.e. carrying wireless charging receiving module 16 with high precision, high-speed can monitor beads automatically 200 itself motion states, to record the twisted circle number of beads 200 in real time.Meanwhile it being connect by wireless charging receiving module 16 The electric energy for receiving external general wireless charging emitting mould train transmitting, charges to built-in power supply 21, makes beads 200 is daily Battery is replaced in the process, charging or opening shell 21 without plug wire.In this way, the governor circuit of 200 internal module of beads Construction can greatly improve circuit level, reduce circuit volume and improve meter circle reliability simultaneously, greatly improve beads 200 Meter circle precision avoids plug wire charging or the frequent replacement of disposable battery to the integrally-built destruction of beads 200, thus significantly Improve the product reliability of beads 200.

Each technical characteristic of above embodiments can be combined arbitrarily, for simplicity of description, not to above-described embodiment In each technical characteristic it is all possible combination be all described, as long as however, the combination of these technical characteristics be not present lance Shield all should be considered as described in this specification.

Above embodiments only express the several embodiments of the utility model, and the description thereof is more specific and detailed, but simultaneously The limitation to utility model patent range therefore cannot be interpreted as.It should be pointed out that for the ordinary skill people of this field For member, without departing from the concept of the premise utility, various modifications and improvements can be made, these belong to this reality With novel protection scope.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
