Description
Technical Field
The invention relates to a TWS earphone with charging reset function.
Background
The TWS earphone is a new earphone at present and consists of a master earphone and a slave earphone, wherein Bluetooth chips are respectively arranged in the master earphone and the slave earphone. When the TWS earphone is activated, the master earphone performs Bluetooth communication with the mobile phone and performs Bluetooth communication with the slave earphone, so that no data line exists between the mobile phone and the master earphone or between the master earphone and the slave earphone, and real wireless interconnection is realized. However, the conventional TWS earphone has problems, and here, the charging of the slave earphone is taken as an example, and the master earphone is similar to the following example: when the TWS headset is used, the master headset and the slave headset establish Bluetooth communication, and if the slave headset needs to be charged, the slave headset needs to firstly report to the master headset to inform the master headset of disconnecting the Bluetooth communication. However, the slave earphone itself does not know when to be charged, and only when the slave earphone is charged in the charging box, the charging pin on the Bluetooth chip for connecting to the charging box to get electricity becomes high potential, but the problem is that the existing slave earphone Bluetooth chip is connected in series with a signal conversion circuit between the charging pin and a reset pin, once the charging pin becomes high potential, the high potential becomes low potential after passing through the signal conversion circuit and is output to the reset pin of the Bluetooth chip, so that the Bluetooth chip starts to be charged, reset and shut down, and no time is reserved for the slave earphone to report to the master earphone.
When facing the problem, the existing TWS earphone directly eliminates the charging reset function, but once the earphone is halted, the earphone cannot be recovered to be normal in a reset mode; another solution is to provide a key on the master or slave earphone, for example, in the above case, the user actively triggers the slave earphone to report to the master earphone and disconnect the bluetooth communication by pressing the key, and then charging is performed. However, the manner of setting the keys can solve the problem, but the main earphone or the auxiliary earphone becomes larger due to the fact that the keys are set, so that the main trend of making the earphone small is not met.
Disclosure of Invention
The invention aims to enable a main earphone or a slave earphone of the TWS earphone to report to the other earphone before the charging reset under the premise of not setting keys.
The aim of the invention is realized by the following technical scheme:
the utility model provides a TWS earphone that area charges and resets, its main earphone and/or from earphone embeds there are bluetooth chip and signal providing circuit, and this bluetooth chip is equipped with the charge pin that gets the electricity to the outside under the charge state and is used for receiving reset signal's reset pin, signal providing circuit is delay reset circuit, delay reset circuit's input electricity connection charge pin in order to gather voltage, delay reset circuit's output electricity is connected to reset pin, delay reset circuit gathers charge pin and has voltage then sends reset signal to reset pin after delay time T.
Wherein the delay reset circuit is a delay reset chip or an analog circuit or a logic circuit.
The delay reset circuit takes power from the charging pin.

Fig. 1 is a circuit diagram of a TWS headset with a charge reset.
Detailed Description
As shown in fig. 1, a bluetooth chip 1 is built in both a master earphone and a slave earphone of the TWS earphone, the bluetooth chip 1 is provided with a charging pin 11 and a reset pin 12, a delay reset circuit 2 formed by a delay reset chip is connected in series between the charging pin 11 and the reset pin 12, wherein an input end of the delay reset circuit 2 is electrically connected with the charging pin 11, and an output end of the delay reset circuit 2 is electrically connected to the reset pin 12. If the slave earphone needs to be charged, the slave earphone is put into the charging box, and at the moment, the charging pin 11 of the Bluetooth chip 1 of the slave earphone is electrically connected with the power supply end in the charging box and is powered, so that the potential of the charging pin 11 is increased. As soon as the bluetooth chip 1 detects that the charging pin 11 becomes high, it is known that the charging is to be performed, the bluetooth chip 1 immediately sends bluetooth data to the main earphone, so as to report to the main earphone. Meanwhile, the delay reset circuit 2 also collects that the potential of the charging pin 11 is high through the input end, and then sends a reset signal to the reset pin 12 after the delay time T so as to pull the reset pin 12 of the Bluetooth chip 1 low. The time T can be 1s, 1.5 seconds or 3s, and the time is preferably in the range of 0.5s to 3 s. The bluetooth chip 1 resets itself upon detecting that the reset pin 12 is pulled low. When the designer selects the time T, the designer may test multiple times, and select the time that takes the longest time to disconnect the bluetooth communication from the headset and the main headset in each test as the time T, so as to ensure that the report has sufficient time. It should be noted that the delay reset circuit 2 in this embodiment is not limited to a delay reset chip, and may be implemented by an analog circuit or a logic circuit, so as to achieve the same design index.
Further, the power-taking end of the delay reset circuit 2 is also electrically connected to the charging pin 11, so that the delay reset circuit 2 takes power from the charging pin 11.
Further, the bluetooth chip 1 is further provided with a trigger pin 13 for sending a trigger signal, the trigger pin 13 is electrically connected with a trigger signal end 21 on the delay reset circuit 2, after the bluetooth chip 1 of the headset sends communication data to the main headset, the bluetooth chip 1 of the headset sends the trigger signal to the delay reset circuit 2 through the trigger pin 13, and the delay reset circuit 2 immediately sends a reset signal after receiving the trigger signal, so that the headset is reset without waiting for a fixed time T, but can be reset at the first time when the bluetooth communication is disconnected from the headset, thereby shortening the time from the headset being put into a charging box to the successful reset, and improving the user experience.
Finally, it should be noted that the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made to the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention.
