The data transmission contact 23 may be used to contact the data transmission contact 13 of the earphone 10, so that the data transmission function such as data transmission and reception between the earphone 10 and the charging box 20 is realized by the contact between the data transmission contact 23 and the data transmission contact 13.
The first contact 21 and the second contact 22 are brought into contact with the first charging contact 11 and the second charging contact 12, respectively, by magnetic attraction, while the data transfer contact 23 and the data transfer contact 13 can be brought into elastic contact. In the case where the first contact 21 is brought into rigid contact with the first charging contact 11 by magnetic attraction and the second contact 22 is brought into rigid contact with the second charging contact 12 by magnetic attraction, the data transfer contact 23 is brought into elastic contact with the data transfer contact 13 by the magnetic attraction of the first contact 21 with the first charging contact 11 and the magnetic attraction of the second contact 22 with the second charging contact 12.
The first charging contact 11, the second charging contact 12, and the data transfer contact 13 will be described in detail below.

The first charging contact 11, the second charging contact 12 and the data transmission contact 13 may be electrically connected (e.g., patch) to a printed circuit board, such as a flexible circuit board (FPC), of the headset 10, and the electrical connection with other electronic components within the headset 10 is achieved through the circuitry of the flexible circuit board. For example, the first charging contact 11, the second charging contact 12, and the data transmission contact 13 may be provided on a housing surface of a leg portion of the headset.
The first contact 21, the second contact 22, and the data transmission contact 23 will be described in detail below.
The first contact 21, the second contact 22 and the data transmission contact 23 may be provided on the charging box housing of the earphone placing area, and may be connected with a printed circuit board of the charging box 20, thereby being electrically connected with other electronic components of the charging box 20.
The first contact 21 and the second contact 22 may be located on both sides of the data transmission contact 23, i.e. the data transmission contact 23 may be located between the first contact 21 and the second contact 22, optionally the three may be located in line, and likewise the first charging contact 11 and the second charging contact 12 may also be located on both sides of the data transmission contact 13 and may be located in line. Other contacts may also be included to perform other functions and may also be located between the first and second contacts 21, 22, in which case the headset may also include contacts corresponding to the other contacts accordingly, according to embodiments of the present disclosure.
The contact between the first contact 21 and the first charging contact 11 may be a rigid contact, and the contact between the second contact 22 and the second charging contact 12 may also be a rigid contact. The first contact 21 and the first charging contact 11, and the second contact 22 and the second charging contact 12 may be made of a magnetic material so that magnetic attraction therebetween can be achieved. For example, the first contact 21 and the second contact 22 may be made of magnets, and the first charging contact 11 and the second charging contact 12 may be made of metallic iron pieces or the like. The data transmission contact 23 is in elastic contact with the data transmission contact 13, in one embodiment of the present disclosure, the data transmission contact 13 is in the form of a metal boss, and the data transmission contact 23 may be in the form of an elastic member, for example, the data transmission contact 23 may be in the form of a pogo pin, for example, including a thimble, a spring and a sleeve, the thimble being located at the upper side and being capable of pushing the spring located in the sleeve to compress. When the data transmission contact 23 is pressed by the data transmission contact 13, the data transmission contact 23 may contract and may be kept in close contact with the data transmission contact 13.
The first contact 21, the second contact 22 and the data transmission contact 23 may be provided at the bottom of a headset receiving groove 24 of the charging box, which receives the headset, at positions corresponding to the contacts of the headset when the headset is put in. The first contact 21 and the second contact 22 may be flush with or protrude a little from the bottom surface of the earphone receiving groove 24, and the data transmission contact 23 may protrude from the bottom surface of the earphone receiving groove 24. According to an embodiment of the present disclosure, the charging box may include two earphone receiving grooves 24, and two earphones are respectively placed, and the first contact 21, the second contact 22, and the data transmission contact 23 are provided in each of the two earphone receiving grooves 24.
One ends of the first contact 21, the second contact 22 and the data transmission contact 23 are in contact with the first charging contact 11, the second charging contact 12 and the data transmission contact 13, respectively, and the other ends of the first contact 21, the second contact 22 and the data transmission contact 23 may be electrically connected to a printed circuit board of the charging box, so that the respective electronic components electrically connected to the charging box, such as the other ends of the first contact 21, the second contact 22 and the data transmission contact 23, may be electrically connected to the circuit board, and in addition, a side wall of a metal boss, such as a metal boss, forming the first contact 21 and the second contact 22 may be securely provided to the housing, such as by embedding, etc., for reinforcing fixation, and a side wall of a sleeve, such as a pogo pin, forming the data transmission contact 23 may also be securely provided to the housing, such as by embedding, etc.
According to the technical scheme of the disclosure, under the condition that the first contact and the first charging contact are in rigid contact through magnetic attraction and the second contact and the second charging contact are in rigid contact through magnetic attraction, the data transmission contact and the data transmission contact are in elastic contact through the magnetic attraction of the first contact and the first charging contact and the magnetic attraction of the second contact and the second charging contact.
According to a specific implementation manner of the present disclosure, for the design of the contacts in the charging box, the two metal bosses can be in the form of one pogo pin, the metal bosses at the two ends are in rigid magnetic contact with the metal bosses of the earphone, and the pogo pin of the charging box in the middle is in elastic contact with the metal bosses of the earphone, so that the risk that one of the contacts cannot be stably contacted due to the seesaw effect can be avoided, and the term is used to realize synchronous stable contact of the three contacts.
When the earphone is put into the charging box, the earphone is introduced into the earphone accommodating groove through the magnetic attraction of the two charging contacts of the earphone and the two charging contacts of the charging box, so that the introduction is realized through the magnetic attraction between the contacts, the inner space of the earphone and the charging box is saved, the saved space can be used for increasing the battery capacity, the service time of the earphone and the charging box after charging is prolonged, and the size of the charging box can be reduced.
It should be noted that the structure of the contact point is described for one wireless earphone, and when there are two or more wireless earphones, the corresponding same structure may be provided, for example, the case of two earphones is shown in the drawings of the present disclosure.
According to an exemplary embodiment of the present disclosure, the earphone charging box of the present disclosure may further include a cover opening detection device. The number of the data transmission contacts is one, and when the data transmission contacts are in electric contact with the data transmission contacts of the earphone, the earphone charging box and the earphone can perform bidirectional data transmission; and the uncovering detection device is used for detecting whether the earphone charging box is in an uncovering state or not, wherein when the uncovering detection device detects that the earphone charging box is in the uncovering state, the earphone charging box and the earphone are allowed to perform bidirectional data transmission through the data transmission contact of the earphone charging box and the data transmission contact of the earphone which are in electrical contact with each other.
According to an optional embodiment of the disclosure, the uncovering detection device comprises a Hall sensor and a magnet, when the earphone charging box is uncovered, the magnet is far away from the Hall sensor, and whether the earphone charging box is in an uncovering state or not is judged by detecting the change of a signal of the Hall sensor.
A schematic view of the lower portion 26 of the headset charging box with a hall sensor 30 mounted therein is shown in fig. 3, wherein the hall sensor 30 is located in the housing of the lower portion 26, the hall sensor 30 being shown in phantom. Although not shown in the drawings, it will be understood by those skilled in the art that a magnet (not shown) may be provided at a position corresponding to the position where the hall sensor 30 is provided in the upper cover 25 of the earphone charging box, and when the magnet is close to or distant from the hall sensor, the output signal of the hall sensor is different due to the difference in the distance of the magnet. When the cover is opened, the magnet is far away from the Hall sensor, the signal output by the Hall sensor changes from high to low, and therefore, when a processor (such as an MCU) connected with the Hall sensor detects that the signal is low, the earphone charging box can be judged to be in an opening state. When the magnet is close to the Hall sensor, the signal of the Hall sensor is changed from low to high, so that when the processor of the earphone charging box detects that the signal of the Hall sensor is high, the earphone charging box can be judged to be in a closed state.
It should be understood that the magnet may be disposed on the lower portion 26 and the hall sensor 30 may be disposed on the upper cover 25. In addition, in addition to the open state of the charging box of the earphone can be detected by the hall sensor and the magnet, other sensing means such as a micro switch (detecting the open state by the vibration of the charging box), a contact switch (determining the open state by detecting the contact of the upper cover and the lower part, for example) can be used.
In distinction from other products, the cover-open communication mode may be employed in the present disclosure and the above-described contact mode may be employed to realize bidirectional data transmission. In other products in the prior art, most of the products do not have a communication mode between the charging box and the earphone when the charging box is opened, and even if the communication mode exists, the communication mode is only realized through Bluetooth or USB. As mentioned earlier, the prior art has a major problem.
The open-cover communication method adopted in the present disclosure may use the wireless headset as a wireless device that is already connected to a mobile terminal (e.g., a smartphone), and the wireless headset may receive data from the mobile terminal and control the data of the wireless headset and the like through bidirectional data communication between the headset and the charging box.
For example, in the present disclosure, data information of the charging box may be delivered to the headset through bidirectional data communication of the headset with the charging box, and transmitted to the mobile terminal through the headset, for example, the power information of the charging box may be transmitted to the headset. For example, the earphone can be controlled by the charging box to be upgraded, the earphone can receive upgrade data from the mobile terminal, at this time, if the earphone needs to be upgraded, the charging box is needed to control the earphone to be upgraded, and after the earphone receives the new version of the upgrade file, the earphone informs the charging box that the earphone receives the new version of the upgrade file through a data transmission contact between the earphone and the charging box, that is, informs the charging box that the earphone receives the upgrade file and can be upgraded. After the charging box receives the signals from the earphones, the earphones are controlled to be upgraded under the condition that the earphone upgrading is met. For example, in the case that there are two earphones, the upgrading sequence of the earphones of the left and right earphones is controlled, for example, the charging box sends an instruction to the earphones to control the earphones to enter the upgrading mode, for example, the charging box controls the earphones to restart or exit the upgrading program after the upgrading is completed, and in addition, the charging box can also control the left and right earphones to be connected with the mobile terminal, and the like.
Next, the wireless headset will be described by taking an example of upgrading the wireless headset. The following mobile terminal may be a smart phone, a tablet computer, a notebook computer, or the like.
If a new version of the upgrade file is downloaded in the earphone, when the cover opening detection unit detects that the earphone charging box is in a cover opening state, the earphone charging box controls the bidirectional data transmission between the earphone and the earphone charging box.
For example, in the case of an upgrade of two wireless headsets, and the two headsets may be divided into a master headset and a slave headset. Firstly, the main earphone is in wireless connection with the mobile terminal, and receives the upgrade file from the mobile terminal in a wireless communication mode. When the earphone charging box is arranged in the main earphone and the slave earphone, the charging box charges for the two earphones, when the cover opening detection device detects the cover opening state, the upgrading file in the main earphone can be transmitted to the slave earphone through the data transmission contact of the charging box, and when the main earphone and the slave earphone all receive the upgrading file, the charging box can control the two earphones to be upgraded. Therefore, in the upgrading stage, the charging box can judge whether the earphones are placed into the charging box or not, if the earphones are judged to be placed into the charging box and in the charging state, and the charging box judges that the earphones are in the uncovering state, the upgrading file transmission of the master earphone and the slave earphone is carried out, and after the transmission is finished, the charging box can control the two earphones to carry out the upgrading mode and the like.
In addition, during the upgrade process of the two wireless earphones, the following mode can also be adopted: the master earphone is respectively in wireless connection with the mobile terminal and the slave earphone, receives the upgrade file from the mobile terminal and sends the upgrade file to the slave earphone. Before the master earphone and the slave earphone are upgraded, whether the electric quantity of the master earphone and the slave earphone is larger than the preset electric quantity or not is judged, if so, the master earphone and the slave earphone are upgraded, and if not, the master earphone and the slave earphone wait for the upgrade. When the two earphones are placed in the charging box and then in the charging state, and the charging box is detected to be in the uncovering state, the charging box is communicated with the two earphones, and the two earphones can be upgraded according to the condition of the upgrade files in the two earphones
According to an optional embodiment of the present disclosure, the headset charging box may further comprise a Universal Asynchronous Receiver Transmitter (UART) or a Universal Synchronous/Asynchronous Receiver Transmitter (USART) configured in a single-wire half-duplex mode for bidirectional data transmission with the data transmission contacts of the headset via one of the data transmission contacts of the headset charging box.
By using the single wire half duplex mode of UART/USART, one data transfer contact can be used to enable two-way communication of the headset with the headset charging box. The UART/USART single-wire half-duplex communication is used without adding any extra part, and the wireless earphone chips support the UART/USART, so that the cost is low.
Specifically, the HDSEL bit of the UART/USART register may be set to "1," which configures the UART/USART to follow the single-wire half-duplex protocol. And in single-wire half-duplex mode, the pins of TX and RX are interconnected in the circuit, and when there is no data transmission, TX appears as a standard I/O port, i.e. when it is not driven by UART/USART, it is configured in a floating-in or open-drain state to output high impedance. During the communication, the line conflict can be managed by software, for example, by using a central arbiter, that is, time-sharing management is performed for receiving and transmitting. For example, when a transmission is made, the transmission continues as long as data is written to the register for data transfer, and when the transmission ends, the stop bit will be transmitted. When the transmission is finished, TX is configured to be a floating input or an open-drain output high impedance, so that single-wire half-duplex communication of UART/USART can be realized.
According to another embodiment of the present disclosure, there is also provided a data transmission method of an earphone charging box. The headset charging box includes a data transfer contact for making electrical contact with the data transfer contact of the headset for bi-directional data transfer. The charging and data transfer can be performed using, for example, the contact structure described above.
As shown in fig. 4, the method includes the step S41 of detecting whether the headset is in an open cover state and the data transmission contacts are in contact, and the step S42 of data transmission between the headset and the charging box.
In step S41, it is detected whether the earphone charging box is in the open-cover state, and whether the wireless earphone and the data transmission contact of the earphone charging box are in contact with each other. In an alternative embodiment, it may also be detected whether the charging nodes are also contacted with each other, and it may also be detected whether the headset is in a charging state.
In step S42, if yes in step S41, bidirectional data transmission between the headset and the charging box may be performed.
Wherein, state detection of uncapping can use detection device that uncaps, and it can include hall sensor and magnet, and when the earphone box that charges uncaps, hall sensor was kept away from to magnet, judges through the change of the signal that detects hall sensor whether earphone box that charges is in the state of uncapping. Of course, other detection means as described above may be selected.
