When a metal or semiconductor sheet, which is supplied with current, is placed vertically in a magnetic field, a potential difference is generated across the sheet, which is known as the hall effect. The Hall switch belongs to the active magnetoelectric conversion device and is manufactured by utilizing integrated packaging and assembling processes on the basis of the Hall effect principle. The Hall switch has wide application range and is applied to brushless motors and earphone charging boxes. Which is in a conducting state by the magnetic field of the induction magnet.
With the development of functions, the internal structure of devices such as an earphone charging box becomes complicated, the space is limited, and the hall switch and the magnet are difficult to be matched in position in space. Therefore, in the prior art, a hall soft board is often used as a connection structure between the hall switch and the main board, so as to reduce the spatial distance between the hall switch and the magnet and relatively fix the position of the hall switch. However, the process of adopting the hall soft board is complex, the cost is high, and the qualification rate of the processed product is high. Therefore, the present invention provides a control module to overcome the deficiencies of the prior art.
Specifically, referring to fig. 1 or 3, fig. 1 or 3 is a schematic diagram of the control module applied to a charging box of an earphone; the control module is used for inducing the magnet 400 to be conducted; wherein, fig. 1 is a closed state of the earphone charging box, and fig. 3 is an open state of the earphone charging box. Control module includes support 100, mainboard 200 and control switch 300, wherein:
the support 100 is connected to the main board 200, and the control switch 300 is electrically connected to the main board 200;
the control switch 300 includes a connection leg 300a extended toward the cradle 100, and the connection leg 300a is connected to the cradle 100 such that the control switch 300 is away from the main board 200 and approaches the magnet 400 movable relative to the control switch 300.
In the present invention, a bracket 100 is installed on a main board 200, and a connection pin 300a is additionally provided on a control switch 300 to be connected to the bracket 100, so that the control switch 300 can be close to a magnet 400 far from the main board 200. Functionally, the control switch 300 is electrically connected to the main board 200; the movement through the magnet 400 may include the effect of one of the following: 1. the control switch 300 can sense the magnetic field of the magnet 400 or cannot sense the magnetic field of the magnet 400; and/or 2, control the magnitude of the magnetic flux of the magnet 400 sensed by the switch 300. For example, the movement of the magnet 400 may include translation (changing the distance between the control switch 300 and the magnet 400) and/or rotation (changing the magnetic pole of the magnet 400 to change the magnetic field range of the magnet 400). According to the technical scheme, the labor consumption can be saved, the cost is reduced, and the technical scheme can be used under the conditions that the layout space of the mainboard is limited and the internal structure space is limited, so that the reliability and the yield of products are ensured.
As a further aspect of the above embodiment, the stand 100 has a foot hole into which the connection foot 300a extends.

Further, the foot hole and the connecting foot 300a are matched in shape, for example, the foot hole and the connecting foot are circular in cross section.
Further, the connection pin 300a may be a dupont pin, which is connected to the housing of the control switch 300, such as being screwed, welded, riveted, clamped, etc.
As shown in fig. 1 or 3, in the case where the connection pin 300a extends into the pin hole, the longitudinal distance between the control switch 300a and the main board is greater than or equal to the height of the stand 100, and thus, the control switch 300 can be made to be close to the magnet 400 in the longitudinal direction. The length of the connecting leg 300a can be selected according to the height of the main board and the space size of the installation position; for example, if the height of the main board is too high, it may easily interfere with other structures when the space size is small, and since the height of the main board may not satisfy the distance between the control switch 300a and the magnet in the longitudinal direction, the longer connecting leg 300a may be selected, and a part of the connecting leg 300a is outside the cradle 100, and the control switch 300 is far away from the cradle 100 and close to the magnet.
As a further aspect of the above embodiment, the control module further comprises a mounting cavity (not labeled); this installation cavity can be other structural constructions, for example to the earphone box that charges, it can be that the earphone holds the installation cavity of the size of the fit control switch 300 appearance that constructs on the storehouse body for fix control switch 300's circumference, prevent rocking of control switch 300. Referring to fig. 1 or 3, the mounting cavity and the support 100 are respectively located at two opposite ends of the control switch 300; wherein the control switch 300 is embedded in the installation cavity to fix the control switch 300 in a state that the connection pin 300a is extended to the cradle 100.
As a further aspect of the above embodiment, the lateral distance L between the control switch 300 and the magnet 400 is 0.5cm to 1.6 cm. The lateral distance is such that the control switch 300 can sense the magnetic field generated by the magnet 400. Or when the second case provided with the first magnet 400 is covered on the first case, the lateral distance between the control switch 300 and the magnet 400 is 0.5cm to 1.6 cm. For example, the lateral distance between the control switch 300 and the magnet 400 may be 0.5cm, 0.6cm, 0.7cm, 0.8cm, 0.9cm, 1.0cm, 1.1cm, 1.2cm, 1.3cm, 1.4cm, 1.5cm, or 1.6 cm.
Further, theoretically, the smaller the lateral distance between the control switch 300 and the magnet 400, the more the control switch 300 can induce the magnetic field of the magnet 400. Thus, the smaller the lateral distance between the control switch 300 and the magnet 400, the better, where structurally allowed.
