For convenience of description and understanding below, the first induction coil 4 corresponding to the left earphone receiving slot is hereinafter referred to as an earphone box left induction coil, the first induction coil 4 corresponding to the right earphone receiving slot is hereinafter referred to as an earphone box right induction coil, the second induction coil set in the left earphone is hereinafter referred to as an earphone left induction coil, and the second induction coil set in the right earphone is hereinafter referred to as an earphone right induction coil.

Specifically, referring to fig. 1, in the present embodiment, the earphone box includes a control module 1, a power module 2, a circuit switching module 3, two first induction coils 4 arranged at intervals, and a box-in detection module 5. The circuit switching module 3 includes a first circuit unit 31, a second circuit unit 32, and a third circuit unit 33.

Specifically, the power module 2 is electrically connected to the control module 1 to provide the power required for operation and the current power information of the earphone box to the control module 1. The circuit switching module 3 is electrically connected to the control module 1, and the circuit switching module 3 is used for switching the working modes of the earphone box by receiving different signals output by the control module 1 and activating circuit units corresponding to the signals, so as to realize the switching between different functions of the earphone box.

The in-box detection module 5 is electrically connected to the control module 1, and is used for detecting whether the earphone is placed in the earphone box. When the earphone is placed in the earphone box, the box entering detection module 5 sends a box entering signal to the control module 1, when the earphone leaves the earphone box, the box entering detection module 5 sends a box leaving signal to the control module 1, and the control module 1 outputs a corresponding control signal according to the received box entering signal or the box leaving signal.

The first circuit unit 31 is electrically connected between the two first induction coils 4 and the power supply module 2 along the first guide. When the control module 1 activates the first circuit unit 31, the first circuit unit 31 is in a conductive state, and then the two first induction coils 4 and the power module 2 are in a conductive state along the first direction, and the power module 2 can supply current to the two first induction coils 4, so that the two first induction coils 4 generate a changing magnetic field. When the earphone is placed in the earphone box, the second induction coil in the earphone can receive the changing magnetic field generated by the first induction coil 4 and generate charging current so as to charge the battery in the earphone, and then the function of charging the earphone by the earphone box is realized.

The second circuit unit 32 is electrically connected between the two first induction coils 4 and the control module 1. When the control module 1 activates the second circuit unit 32, the second circuit unit 32 is in a conductive state, and the two first induction coils 4 are respectively in a communication state with the control module 1. When the earphone is placed in the earphone box, the control module 1 can send communication signals to the second induction coil in the earphone through the second circuit unit 32 and the first induction coil 4 in the on state, and can also receive feedback signals sent by the second induction coil of the earphone, so that the communication function between the earphone box and the earphone is realized, and the earphone box can acquire the current information of the earphone.

The third circuit unit 33 is electrically connected between the two first induction coils 4 and the power module 2 along a second guide, and the first guide is opposite to the second guide. When the control module 1 activates the third circuit unit 33, the third circuit unit 33 is in a conducting state, and then the two first induction coils 4 and the power module 2 are in a conducting state along the second direction, and as the first direction is opposite to the second direction, the two first induction coils 4 can generate charging current by receiving a changing magnetic field generated by the second induction coil of the earphone placed in the earphone box, so as to charge the power module 2 of the earphone box, thereby realizing the function of reversely charging the earphone box by the earphone, adapting to the situation that the electric quantity of the earphone box is completely used up when a user uses the earphone box, and the earphone still has electric quantity.

It can be understood that the control module 1 controls the circuit switching module 3, so that the first circuit unit 31, the second circuit unit 32 and the third circuit unit 33 can be activated independently to control the conducting state between the first induction coil 4 and different modules, further trigger different working modes of the earphone box, start different functions of the earphone box, and solve the problem of short circuit or poor contact caused by setting pins or contacts exposed in air on the earphone box while integrating the earphone box into the first induction coil 4.

After the earphone is placed in the earphone box, the in-box detection module 5 detects that the earphone is placed in the earphone box, the control module 1 periodically activates the second circuit unit 32, and the control module 1 sends a communication signal to the earphone placed in the earphone box through the first induction coil 4 and the second circuit unit 32 in a conducting state, so that the current electric quantity state of the earphone placed in the earphone box is obtained. After the control module 1 obtains the current electric quantity state of the earphone placed in the earphone box, if it is determined that the earphone needs to be charged, the control module 1 activates the first circuit unit 31, and the power module 2 charges the earphone placed in the earphone box through the first induction coil 4 and the first circuit unit 31 in a conducting state.

The control module 1 is electrically connected with the power module 2, the control module 1 can acquire the current electric quantity state of the earphone box in real time, the third circuit unit 33 is in an off state under the condition that the current electric quantity of the earphone box meets the preset electric quantity requirement, and when the current electric quantity of the earphone box does not meet the preset electric quantity requirement, the third circuit unit 33 is activated, namely the third circuit unit 33 is in an on state, so that the first induction coil 4 and the power module 2 are in a state capable of being conducted along the second guide, and further the first induction coil 4 can receive a conversion magnetic field generated by the second induction coil in the earphone and generate induction current to charge the power module 2.

Further, referring to fig. 1, in one embodiment, the circuit switching module 3 further includes a fourth circuit unit 34, and the fourth circuit unit 34 is electrically connected between the two first induction coils 4.

When the control module 1 activates the fourth circuit unit 34, that is, the fourth circuit unit 34 is in a conductive state, the left induction coil of the earphone box and the right induction coil of the earphone box are in a communication state. For example, if the left induction coil of the earphone box receives the changing magnetic field generated by the corresponding second induction coil, the left induction coil of the earphone box generates an induction current, and the induction current can flow through the right induction coil of the earphone box through the fourth circuit unit 34 in a conducting state, and the right induction coil of the earphone box generates the changing magnetic field, so as to charge the earphone corresponding to the right induction coil of the earphone box, thereby realizing the function of reverse charging between two earphones placed in the earphone box.

It can be appreciated that the electric quantity of the earphone box is usually provided with a bottom-protecting electric quantity, and when the electric quantity of the earphone box is lower than or equal to the bottom-protecting electric quantity, the earphone box can stop charging the earphone so as to ensure that the earphone box has enough electric quantity to perform functions of pairing connection of the earphone or communication with the earphone and the like. In the process of using the earphone box by a user, due to the use mode of the user or the consumption difference of the electric quantity of the main earphone and the auxiliary earphone, the situation of unbalance of the electric quantity of the left earphone and the right earphone possibly exists, and when the electric quantity of the earphone box is lower than the bottom-protecting electric quantity, the earphone box cannot supplement the electric quantity for the earphone, and the earphone with the unbalance electric quantity possibly influences the use experience of the user.

Therefore, after the in-box detection module 5 detects that two earphones are all placed in the accommodating groove of the earphone box, the control module 1 obtains the current electric quantity of the two earphones and the earphone box through the second circuit unit 32 and the power module 2, if the current electric quantity of the earphone box is equal to or lower than the bottom-protecting electric quantity and the difference value of the current electric quantity of the two earphones is larger, the control module 1 activates and sends a reverse charging starting signal to the earphone with the larger current electric quantity value through the second circuit unit 32, after sending the reverse charging starting signal, the control module 1 activates the fourth circuit unit 34, the two first induction coils 4 are mutually communicated, and after the earphone with the larger electric quantity value starts reverse charging, the reverse charging between the two earphones is started.

For example, if the earphone with a larger electric quantity value is a left earphone, after the earphone box left induction coil receives the changing magnetic field generated by the earphone box left induction coil, the earphone box left induction coil generates an induction current, the induction current flows through the earphone box right induction coil through the conducted fourth circuit unit 34, the earphone box right induction coil generates the changing magnetic field, and after the earphone right induction coil receives the changing magnetic field, the earphone right induction coil generates a charging current to charge the right earphone, so that a reverse charging function between the two earphones is realized.

Further, referring to fig. 1, in one embodiment, the earphone box further includes a charging end 6, and the charging end 6 is electrically connected to the control module 1 and the power module 2, respectively. The charging terminal 6 may be a charging interface or a charging coil.

It can be understood that the charging terminal 6 is electrically connected to the control module 1, the control module 1 can obtain the voltage values of the two ends of the charging terminal 6 to determine whether the charging terminal 6 is connected to an external power supply, and if the voltage values of the two ends of the charging terminal 6 are about 0 v, it is indicated that the charging terminal 6 is not connected to the power supply; if the voltage across the charging terminal 6 is about 5 v, it indicates that the charging terminal 6 is connected to the power supply.

Under the condition that the third circuit unit 33 is in a conducting state, that is, the earphone box starts a function of reversely charging the earphone box by the earphone box, if the control module 1 detects that the voltage value of the two ends of the charging end 6 is about 5 volts, the control module 1 releases the conducting state of the third circuit unit 33, that is, under the condition that the earphone box is in a mode of reversely charging the earphone box by the earphone, if the earphone box is externally connected with an external charging power supply, the earphone box exits from the mode of reversely charging the earphone box by the earphone. Similarly, when the control module 1 detects that the voltage value across the charging terminal 6 is about 5 v while the fourth circuit unit 34 is in the on state, the control module 1 releases the on state of the fourth circuit unit 34.

Further, referring to fig. 1, in one embodiment, the earphone box further includes an external placement module 7 and a trigger module 8, the circuit switching module 3 further includes a fifth circuit unit 35, the fifth circuit unit 35 is electrically connected between the first induction coil 4 and the external placement module 7, the trigger module 8 is electrically connected to the control module 1, and the power module 2 is electrically connected to the external placement module 7. The external amplifying module 7 includes a pre-amplifying unit, a power amplifying unit and a speaker unit, wherein the pre-amplifying unit is electrically connected to the fifth circuit unit 35, and the power amplifying unit is electrically connected between the pre-amplifying unit and the speaker unit.

Specifically, the trigger module 8 is configured to send a first signal and a second signal to the control module 1. After receiving the first signal, the control module 1 activates the fifth circuit unit 35, and the fifth circuit unit 35 is in a conductive state. In some embodiments, the control module 1 further obtains a current electric quantity state of the earphone box after receiving the first signal, and if the current electric quantity of the earphone box meets the requirement, the control module 1 activates the fifth circuit unit 35, and the fifth circuit unit 35 is in a conductive state; in the process that the fifth circuit unit 35 is in the on state, if the control module 1 obtains that the current electric quantity of the earphone box does not meet at least one of the requirement and the receiving of the second signal, the control module 1 will disconnect the fifth circuit unit 35.

When the control module 1 activates the fifth circuit unit 35, the fifth circuit unit 35 is in a conductive state, and the two first induction coils 4 and the external module 7 are in a communication state through the fifth circuit unit 35 in the conductive state, so that the earphone box is in an external mode. When the earphone box and the earphone are both started to play the function, and the earphone is placed in the earphone box, if the earphone and the terminal are in a communication connection state and play audio, the second induction coil in the earphone can generate a changing magnetic field, the first induction coil 4 in the earphone box can generate induction current after receiving the changing magnetic field generated by the second induction coil, and the induction current can flow to the play module 7 through the fifth circuit unit 35 in a conducting state, so that the play function of the earphone box is realized.

Further, the triggering module 8 includes an input unit 81 and an open box detecting unit 82, and the input unit 81 and the open box detecting unit 82 are electrically connected to the control module 1 respectively. The input unit 81 is used for inputting a first trigger signal for activating the fifth circuit unit 35 and a second trigger signal for disconnecting the on state of the fifth circuit unit 35, the open box detection unit 82 is used for inputting an open box signal and a close box signal, preferably, the input unit 81 may be a function key arranged on the earphone box, and the open box detection unit 82 may be a hall detection sensor.

When the control module 1 detects that the user uses the first trigger signal output by the input unit 81 and the box opening signal output by the box opening detection unit 82 (i.e., the trigger module 8 outputs the first signal), the control module 1 activates the fifth circuit unit 35, the fifth circuit unit 35 is in a conductive state, and the earphone box starts the play function. When the control module 1 detects at least one of the second trigger signal and the closing signal input by the user through the input unit 81, the control module 1 opens the on state of the fifth circuit unit 35, and the earphone box exits the play function.

It can be understood that the function of putting the earphone box is realized by electromagnetic induction between the first induction coil 4 arranged in the earphone box and the second induction coil arranged in the earphone, that is, the earphone arranged in the earphone box is equivalent to an intermediate medium for realizing the function of putting the earphone box. When the function of putting the earphone box outside is used, since the earphone is placed in the earphone box, in order to ensure the communication connection between the earphone and the terminal and ensure that the earphone can receive the audio data of the terminal, it is necessary to ensure that the earphone box is in a cover-opening state so as to avoid disconnection between the earphone and the terminal after the earphone box is closed, so that the control module 1 needs to detect the first trigger signal and the box-opening signal before activating the fifth circuit unit 35.

Still further, referring to fig. 2, in a preferred embodiment, the earphone box further includes a control switch 9 corresponding to the first induction coil 4 one by one, the control switch 9 is electrically connected to the control module 1, the control switch 9 is electrically connected between the first circuit unit 31 and the first induction coil 4, and the control switch 9 is electrically connected between the fifth circuit unit 35 and the first induction coil 4.

It can be understood that the control switches 9 are in one-to-one correspondence with the first induction coils 4, and the control switches 9 are electrically connected to the control module 1, so that the control switches 9 can control the conduction states between the corresponding first induction coils 4 and the first circuit unit 31 and the fifth circuit unit 35 respectively under the control of the control module 1. After the control switch 9 is set, if the earphone box is to start the charging function of the corresponding earphone, the first circuit unit 31 and the corresponding control switch 9 are required to be in a conducting state; if the play function of the earphone box is to be started, it is required to satisfy that the fifth circuit unit 35 and the corresponding control switch 9 are in a conductive state.

Specifically, referring to fig. 2, the control switch 9 includes a box switch 91, and the box switch 91 is electrically connected to the control module 1.

It is easy to understand that by providing the in-box switches 91 in one-to-one correspondence with the first induction coils 4, it is possible to control the on state of the corresponding lines according to the situation in which the earphone is put into the earphone box. For example, when the in-box detection module 5 detects that only the left earphone is put into the earphone box, the in-box detection module 5 sends an in-box signal of the left earphone to the control module 1, after receiving the in-box signal of the left earphone, the control module 1 only turns on the in-box switch 91 corresponding to the left induction coil of the earphone box, if the control module 1 activates the first circuit unit 31, the left induction coil of the earphone box is in a conductive state with the power module 2, and then the left induction coil of the earphone box charges the left earphone; if the control module 1 activates the fifth circuit unit 35, the earphone box left induction coil starts to receive the varying magnetic field generated by the earphone left induction coil and transmits the generated induction current to the external module 7.

Further, referring to fig. 2, the control switch 9 further includes a power switch 92, and the power switch 92 is electrically connected to the control module 1.

It can be understood that by providing the power switches 92 corresponding to the first induction coils 4 one by one, the corresponding conductive lines can be controlled according to the power condition of the earphone. For example, when the in-box detection module 5 detects that both the left and right earphones are put into the earphone box, the in-box detection module 5 sends an in-box signal to the control module 1, the control module 1 turns on the in-box switch 91 and the power switch 92 corresponding to the first induction coil 4 after receiving the in-box signal, if the control module 1 activates the first circuit unit 31, the first induction coil 4 charges the earphones, and in the charging process, if the power of one of the earphones is full, the control module 1 controls the power switch 92 corresponding to the fully charged earphone to be turned off, and when the earphones are fully charged, the control module 1 turns off the first circuit unit 31 and turns on the power switch 92 again. If the control module 1 activates the fifth circuit unit 35, the trigger switch remains in the conductive state all the time. In the process of activating the first circuit unit 31 or the fifth circuit unit 35, if the in-box detection module 5 detects that the earphone leaves the earphone box, the control module 1 controls the in-box switch 91 and the power switch 92 corresponding to the earphone leaving the earphone box to be turned off.

Through setting up the income box switch 91 and the electric quantity switch 92 with first induction coil 4 one-to-one, can realize controlling the conduction state between corresponding first induction coil 4 and first circuit unit 31, the fifth circuit unit 35 respectively, and then can realize realizing the individual control to the functional circuit according to the concrete circumstances of earphone, can adapt to the service scenario of earphone box better, simultaneously, can effectively reduce the unnecessary electric quantity loss of earphone box.

Further, referring to fig. 2, the earphone box further includes a timing module 10 electrically connected to the control module 1, and the timing module 10 is configured to time the activation period of the fifth circuit unit 35.

It will be appreciated that when the control module 1 activates the fifth circuit unit 35, the control module 1 controls the power module 2 to start supplying power to the discharging module 7 when the fifth circuit unit 35 is in the on state. In the process that the user uses the earphone box play function, there may be a case that the user does not put the earphone into the earphone box after the user starts the play function of the earphone box. By arranging the timing module 10 in the earphone box, when the control module 1 activates the fifth circuit unit 35, the control module 1 will send a start timing signal to the timing module 10 at the same time, the timing module 10 starts timing after receiving the start timing signal, and before the timing duration of the timing module 10 reaches the preset duration, if the in-box detection module 5 detects that the earphone is put into the earphone box, the control module 1 sends a reset signal to the timing module 10, and after the timing module 10 receives the reset signal, the timing module 10 resets and stops timing; if the in-box detection module 5 still does not detect that the earphone is put into the earphone box when the timing duration reaches the preset duration, the timing duration is reset and stops timing, and meanwhile, a timeout signal is sent to the control module 1. After receiving the timeout signal, the control module 1 disconnects the conducting state of the fifth circuit unit 35, and simultaneously controls the power supply module 2 to stop supplying power to the outward-discharging module 7, so that the earphone box exits the outward-discharging mode, further the timeout automatic exit function of the outward-discharging mode of the earphone box is realized, and the unnecessary loss of the electric quantity of the earphone box can be effectively reduced.

In summary, according to the earphone box provided by the utility model, the first induction coil 4 and the circuit switching module 3 are arranged in the earphone box, so that pins or contacts are prevented from being arranged on the earphone box, the problems that the pins or contacts are single in function and short circuit and poor contact are easy to occur are solved, meanwhile, the multifunctional integration of the earphone box is realized, the use of additional devices is reduced, and the cost of the earphone box is reduced.

The utility model also provides an earphone assembly, which comprises the earphone box and two earphones which can be matched with the earphone box for use, wherein a second induction coil which can be matched with the first induction coil 4 is arranged in the earphone.

The above description and drawings should not be taken as limiting the scope of the utility model in any way, but rather should be understood to cover all modifications, structural equivalents, or direct/indirect applications of the utility model in the light of the general principles of the present utility model which may be employed in the present utility model and illustrated by the accompanying drawings.
