Embodiment Construction
[0020] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0021] In view of the aforementioned problem that it is currently impossible to perform disconnection detection on the battery line of the finished neckline Bluetooth headset, the present invention attaches two wires drawn from the headset wire control box that are respectively connected to the left and right batteries of the headset on the two detection sensors. Connect the relay to the power interface in the wire control box, and control the conduction of the relay through the single-chip microcomputer, so that the relay can charge the left and right batteries respectively, and then collect the magnetic field signals formed outside the two wires through the corresponding detection sensors, so that according to the collected The magnetic field signals respectively determine whether there is an open circuit between the left and right batteries ...

The invention provides a broken circuit detection device and detection method for earphone batteries. According to the device, two wires that are drawn from an earphone wire control box and are separately connected with left and right batteries of an earphone are separately attached to two detection sensors, a relay is connected with a power interface in the wire control box, the relay is controlled to turn on through a single-chip microcomputer, and thus the relay separately supplies power to the left and right batteries, and then magnetic field signals formed outside the two wires are separately acquired through the corresponding detection sensors, and thus whether broken circuit phenomena exist between the left and right batteries and the corresponding wires can be separately determinedaccording to the acquired magnetic field signals. The scheme of the invention has the advantages of simple structure, low cost and convenient operation, the battery wires of finished product class neckline earphones can be detected, the outgoing quality of the finished product class neckline earphones can be improved, and the production and manufacturing costs of enterprises can also be reduced.
Description
technical field [0001] The present invention relates to the technical field of earphones, and more specifically, to an earphone battery disconnection detection device and detection method. Background technique [0002] At present, the most widely used Bluetooth technology in daily life is the Bluetooth headset. Its biggest feature is portability and wireless operability, so that users can use mobile phones even in places where it is inconvenient to hold mobile phones. Current bluetooth earphones, in order to improve its battery life, usually adopt dual batteries, that is, the bluetooth earphone has two batteries, wherein one battery is put together with the left earphone speaker, and the other battery is put together with the right earphone speaker. [0003] However, for neckline Bluetooth headsets with dual batteries, the risk of unilateral circuit breakage is high, and for finished product testing, it is no longer possible to judge whether the bilateral batteries are quali...
