Specifically, a pivot is disposed on one side edge of the box cover 20/box body 10, and the corresponding side edge of the box body 10/box cover 20 is connected to the pivot and rotates around the pivot to complete the covering action. Certainly, the box cover 20 and the box body 10 can be turned over by hinges, and at this time, the corresponding sides of the box cover 20 and the box body 10 are respectively connected with the hinges, and the closing action is completed by opening and closing the hinges.
The circuit board 30 is disposed in the case 10, and the control circuit 50 is printed on the circuit board 30. Preferably, the circuit board 30 is disposed in the case body 10 and close to the lower end surface of the case body 10, so as to minimize the distance from the circuit board 30 to the lower end surface of the case body 10, thereby facilitating to reduce the overall height of the earphone charging box 100, so as to miniaturize the earphone charging box 100.
The upper end surface of the box body 10 forms an accommodating cavity 11 corresponding to the outline of the earphone, the lower end surface of the box cover 20 forms an accommodating groove 21 corresponding to the accommodating cavity 11, when the box cover 20 is covered on the box body 10, the accommodating groove 21 is butted with the accommodating cavity 11 as shown in fig. 3, and the earphone is limited in the accommodating cavity 11, so that the earphone is limited and fixed in the earphone charging box 100.
Referring to fig. 3 and 4, the sensing assembly 40 includes a magnetic component 41, a metal component 42 and a hall sensing unit 43, wherein the magnetic component 41 is disposed in the case cover 20, and the metal component 42 is disposed in the case body 10, so that the appearance of the case is more attractive. Specifically, when the box cover 20 is covered on the box body 10, the metal member 42 and the magnetic member 41 have a first distance h therebetween. The magnetic member 41 is disposed on the inner wall of the lower end face of the box cover 20, and the metal member 42 is disposed on the inner wall of the upper end face of the box body 10, so that when the box cover 20 is covered on the box body 10, only the inner wall of the lower end face of the box cover 20 and the inner wall of the upper end face of the box body 10 are separated between the magnetic member 41 and the metal member 42, and under the condition that the magnetic flux of the magnetic member 41 is constant, the magnetic member 41 can ensure that the metal member 42 can be optimally adsorbed, so that the box cover 20 can be stably covered on the box.
Certainly, the magnetic element 41 may be disposed on the box cover 20, and the metal element 42 is correspondingly disposed on the box body 10, at this time, the magnetic element 41 and the metal element 42 are both directly exposed to the external environment, when the box cover 20 covers the box body 10, the magnetic element 41 directly adsorbs the metal element 42, and at this time, the magnetic element 41 has the maximum adsorption force on the metal element 42. The magnetic member 41 in this embodiment is specifically a magnet, and the metal member 42 is specifically an iron member such as an iron rod or an iron block, and the magnet attracts the iron member to keep the box cover 20 and the box body 10 in a closed state. Of course, the metal member 42 may be other metal having magnetic conductivity, and the material of the metal member 42 is not limited herein on the premise that the magnetic field of the magnetic member 41 can be effectively conducted to the metal member 42.
The hall sensing unit 43 is disposed on the circuit board 30 and electrically connected to the control circuit 50, and preferably, the model of the hall sensing unit 43 is AL901, and the hall sensing unit 43 of this model has low price and relatively high detection accuracy, and is suitable for large-scale use. Preferably, when the box cover 20 is covered on the box body 10, the magnetic member 41, the metal member 42 and the hall sensing unit 43 are positioned on the same straight line, so that the magnetic member 41 can attract the metal member 42 at the front side, and the hall sensing unit 43 can detect the magnetic field of the metal member 42 at the shortest distance.
The hall sensing unit 43 is attached to the circuit board 30 by a chip mounting process to reduce the protruding height of the hall sensing unit 43 relative to the circuit board 30. When the box cover 20 is covered on the box body 10, the magnetic member 41 adsorbs the metal member 42 and transmits the magnetic field to the metal member 42, the hall sensing unit 43 detects the magnetic field intensity of the metal member 42 and generates a detection signal, and the control circuit 50 detects the closing state of the earphone charging box 100 according to the detection signal. Specifically, when the control circuit 50 receives the detection signal, the control circuit 50 determines that the earphone charging box 100 is in the closed state, and at this time, the control circuit 50 may perform a series of operations such as charging the earphone; when the control circuit 50 receives no detection signal, the control circuit 50 determines that the earphone charging box 100 is in the open state, and the control circuit 50 does nothing.
Referring to fig. 3, when the magnetic member 41 is a magnet and the metal member 42 is an iron member, in order to enable the earphone charging box 100 to have a better locking effect when being in the closed state and the hall sensing unit 43 to have a better detection effect, the first distance h of the embodiment is between 3mm and 10mm, and the first distance h is adjusted to be between 3mm and 10mm, so as to limit the magnetic member 41 to have a better adsorption force on the metal member 42 when the first distance h is set, so as to maintain the closed state of the earphone charging box 100 and effectively transmit the magnetic field of the magnetic member 41 to the metal member 42.
Accordingly, the second distance H between the hall sensing unit 43 and the metal member 42 of the present embodiment is between 5mm and 15mm, and the second distance H is adjusted to be between 5mm and 15mm, so as to prevent the hysteresis in the metal member 42 from affecting the detection accuracy of the hall sensing unit 43, which specifically affects: assuming that the second distance H is too small (e.g., close to zero), the magnetic field of the magnetic member 41 is partially conducted to the metal member 42 and stagnates in the metal member 42, and the hall sensing unit 43 detects the magnetic field of the metal member 42 to determine that the charging box 100 of the earphone is in the closed state. However, when the earphone charging box 100 is switched from the closed state to the open state, the retained magnetic field of the metal member 42 cannot be dissipated in time, and the hall sensing unit 43 continuously detects the magnetic field of the metal member 42 and continuously determines that the earphone charging box 100 is in the closed state, so that misjudgment is generated, and detection failure is caused, and therefore, the second distance H is adjusted to be between 5mm and 15mm, and the misjudgment problem can be effectively solved.
Furthermore, the second distance H of the present embodiment is greater than the first distance H, and repeated experiments show that when the second distance H is greater than the first distance H, the hall sensing unit 43 can be effectively prevented from being erroneously determined due to hysteresis of the metal component 42, thereby further improving the detection accuracy of the earphone charging box 100 of the present embodiment.
It should be noted that the first and second pitches H and H related to the present embodiment should be specifically set according to the attraction characteristics of the magnetic member 41 and the metal member 42 to meet different production requirements.

Through the setting, the Hall sensing units 43 of different models can be adopted according to different application requirements so as to meet the production requirements of customers. Of course, the number of the sensing elements 40 may also be three, four or five, and the setting and determining manners of the sensing elements 40 with different numbers are similar to those described above, and are not described herein again.
With reference to fig. 1-5, the hall sensing unit 43 of the present invention is disposed on the circuit board 30 and electrically connected to the control circuit 50, when the cover 20 covers the case body 10, the magnetic component 41 adsorbs the metal component 42, and transmits the magnetic field to the metal component 42, the hall sensing unit 43 detects the magnetic field strength of the metal component 42 and generates the detection signal, the control circuit 50 detects the closed state of the earphone charging case 100 according to the detection signal, on one hand, the hall sensing unit 43 detects the magnetic field strength of the metal component 42 to indirectly detect whether the cover 20 covers, so that the hall sensing unit 43 is not required to be disposed at a position close to the magnetic component 41, and the hall sensing unit 43 can be flexibly disposed; on the other hand, the hall sensing unit 43 is directly electrically connected to the control circuit 50, and there is no need to provide an additional dedicated circuit board 30 for the hall sensing unit 43, which is simple in structure, and effectively reduces the number of circuit boards 30 and the overall volume of the earphone charging box 100.
The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, therefore, the invention is not limited thereto.
