Detailed Description

It should be noted that, in the present application, the embodiments and features of the embodiments may be combined with each other without conflict. The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

The present invention provides an earphone wire storage box 10, as shown in fig. 1-6, the earphone wire storage box 10 includes a housing 11, a winding member 12 for winding an earphone wire (not shown), an elastic member 13, and a conductive member 14. The housing 11 has an accommodating cavity (not shown), a fixing shaft 111 is disposed in the accommodating cavity, an outlet 112 and a mounting port 113 are disposed on an outer surface of the housing 11, the outlet 112 is used for an earphone cable to pass through. The winding member 12 is provided with a mounting hole 121, the fixing shaft 111 is mounted in the mounting hole 121 so that the winding member 12 can rotate around the fixing shaft 111, and the elastic member 13 is mounted on the winding member 12 and coupled to the housing 11 to accumulate energy when the winding member 12 rotates in a forward direction (X direction in fig. 1) and to discharge energy when the winding member 12 rotates in a reverse direction (Y direction in fig. 1). Conductive assembly 14 includes a first annular conductive member 141 and a second annular conductive member 142 abutting first annular conductive member 141; the first annular conductive member 141 is fixedly disposed in the accommodating cavity with the fixing shaft 111 as a central axis, and the first annular conductive member 141 is electrically connected to an external module (not shown) for providing a sound signal through the mounting opening 113; the second annular conductive member 142 is mounted on the wire winding member 12 with the fixing shaft 111 as a rotation axis, and the second annular conductive member 142 is used for electrically connecting with an earphone cable.

The earphone cord is installed in the utility model provides a during earphone cord receiver 10, the earphone cord is convoluteed on winding wire 12, the one end of earphone cord is connected on installing the second annular conductive piece 142 on winding wire 12, the other end of earphone cord connection earphone 100 stretches out the outlet 112 of seting up on the casing 11, when pulling out earphone 100, the earphone cord of coiling on winding wire 12 will progressively be pulled out, thereby it is forward-rotated with second annular conductive piece 142 to drive winding wire 12, and drive elastic component 13 energy storage, when earphone 100 needs to be withdrawed, thereby elastic component 13 releases can drive winding wire 12 reverse rotation and withdraw the earphone cord. Because the holding intracavity of casing 11 still sets firmly with second annular conductive piece 142 butt, and the unanimous first annular conductive piece 141 of the rotation axis of center pin and second annular conductive piece 142, so second annular conductive piece 142 can keep the butt relation with first annular conductive piece 141 always when rotating, as long as the module that provides sound signal passes through installing port 113 and is connected with first annular conductive piece 141, just can utilize first annular conductive piece 141 with sound transmission to earphone 100 on, from this, the utility model provides a earphone cord receiver 10 enables the unilateral flexible of earphone cord, consequently the utility model discloses earphone cord receiver 10 of embodiment can apply to on the earphone 100 that can not plug like the built-in earphone 100 of audiphone 1000.

The module for providing the sound signal may be composed of a plurality of components, for example, a microphone (not shown) and an amplifier (not shown) in the hearing aid 1000 may be composed of the module for providing the sound signal, the microphone is used for receiving the ambient sound and converting the ambient sound into a corresponding electrical signal to be transmitted to the amplifier, and the amplifier amplifies the input electrical signal to be transmitted to the earphone 100.

In an embodiment, as shown in fig. 3, the first annular conductive member 141 includes an annular conductive portion 1411 and an elastic contact (not shown). An annular conductive part 1411 is disposed in the accommodating cavity with the fixing shaft 111 as a central axis. The elastic contact is disposed on a side of the annular conductive portion 1411 facing the second annular conductive member 142, and the elastic contact is elastically abutted to the second annular conductive member 142.

If the first annular conductive member 141 and the second annular conductive member 142 are in planar contact, when the second annular conductive member 142 rotates, both the first annular conductive member 141 and the second annular conductive member 142 are easily worn or frictionally deformed, thereby causing poor contact between the first annular conductive member 141 and the second annular conductive member 142. In the embodiment, the first annular conductive member 141 is provided with the elastic contact, and the elastic contact is elastically abutted with the second annular conductive member 142, so that even if the elastic contact and the second annular conductive member 142 are slightly worn, the elastic contact can still maintain the abutting relationship with the second annular conductive member 142 by virtue of the elasticity of the elastic contact.

Alternatively, an equivalent replacement may be made by providing a resilient contact on the second annular conductive member 142.

Specifically, there are various ways of connecting the module for providing the sound signal to the first annular conductive member 141 through the mounting port 113, and two embodiments are listed below for reference:

in one embodiment, as shown in fig. 3 and 4, the module for providing the sound signal is connected to the first annular conductive member 141 through a wire (not shown), specifically, one end of the wire is welded to the module for providing the sound signal, and the other end of the wire is welded to the side of the annular conductive portion 1411 facing away from the second annular conductive member 142 through the mounting opening 113.

In another embodiment, as shown in fig. 3, 4 and 7, the first annular conductive member 141 further includes a conductive pin 1412, one end of the conductive pin 1412 is connected to the annular conductive portion 1411, and the other end of the conductive pin 1412 extends out of the mounting opening 113 for electrically connecting to an external module for providing an audio signal. Specifically, since the conductive pins 1412 protrude out of the mounting openings 113, it is relatively easy to electrically connect the module for providing the sound signal to the conductive pins 1412. The size of the mounting opening 113 of this embodiment can be set to be relatively small, and only the conductive pins 1412 extend out, so that a certain dustproof effect can be achieved.

As a specific implementation manner in some embodiments of the present invention, as shown in fig. 2, fig. 3, and fig. 8, the winding member 12 includes a winding post 122 and a mounting plate 123. A threading opening 1221 is formed in the periphery of the winding post 122 along the radial direction of the winding post 122, and the mounting hole 121 is formed in one end of the winding post 122 along the axial direction of the winding post 122 along the mounting hole 121 of the winding post 122. The mounting plate 123 is connected to the other end of the winding post 122, a line accommodating groove 1231 extending to the inside of the winding post 122 is formed in a surface of the mounting plate 123 opposite to the winding post 122, and the second annular conductive member 142 covers the line accommodating groove 1231. The threading opening 1221 penetrates through the periphery of the winding post 122 and the wire accommodating groove 1231, so that the earphone cord penetrates through the threading opening 1221 and is electrically connected to the second annular conductive member 142.

By implementing this embodiment, one end of the earphone cable connected to the second annular conductive member 142 may pass through the threading opening 1221 at the periphery of the wrapping post 122, enter the wire accommodating groove 1231, and be electrically connected to one side of the second annular conductive member 142 opposite to the first annular conductive member 141. The advantage of this embodiment is that the connection structure between the earphone cord and the second annular conductive member 142 can be hidden by the winding member 12, and will not be exposed outside the winding member 12, which not only can play a role of dust protection, but also is not easy to be damaged.

In an embodiment, a wire-clamping structure (not shown) may be further disposed in the wire-accommodating groove 1231.

When not setting up the card line structure, the back is pulled out completely to the earphone cord, if continue to pull the earphone cord, the hookup location of earphone cord and second annular conductive piece 142 will receive the pulling force, because hookup location is very weak, receives the very easy disconnection of pulling force, leads to the product to become invalid. After the earphone cable is clamped by the cable clamping structure, if the earphone cable is pulled out completely, force only acts on the cable clamping structure, and the connection position between the earphone cable and the second annular conductive piece 142 is not disconnected.

In an embodiment, as shown in fig. 2, 3, 8, and 9, a ratchet 1232 is disposed on a surface of the mounting plate 123 facing away from the winding post 122, and a hollow structure is disposed in a middle portion of the ratchet 1232 to expose the second annular conductive member 142; the containing case of the earphone 100 further includes a pawl 15 elastically disposed on the housing 11, the pawl 15 elastically contacts with the outer peripheral surface of the ratchet 1232, and the pawl 15 is configured to abut against the ratchet 12321 of the ratchet 1232 when the winding member 12 rotates in the reverse direction (Y direction in fig. 1) to limit the release of the elastic member 13.

Specifically, the distances between each point on the outer periphery of the ratchet 1232 and the rotation center line of the ratchet 1232 are not uniform, and the pawl 15 can always be attached to the outer peripheral surface of the ratchet 1232 when the winding member 12 is rotated in the normal direction (X direction in fig. 1), and the pawl 15 is elastically provided in the housing 11, so that the pawl 15 can always be attached to the outer peripheral surface of the ratchet 1232 by the elastic force even when the ratchet 1232 is rotated. When the wire winding member 12 rotates reversely (Y direction in fig. 1) until the pawl 15 abuts against the ratchet 12321 of the ratchet 1232, the pawl 15 will catch the ratchet 1232, so as to limit the release of the elastic member 13, so that the stretched earphone wire will not be retracted into the storage box of the earphone 100. By implementing the present embodiment, the winding member 12 can be adjusted in multiple stages, i.e. the drawn earphone line can be fixed at multiple lengths.

The number of the ratchet teeth 12321 of the ratchet 1232 is not limited in this embodiment, and the number of the steps is adjusted to be larger as the number of the ratchet teeth 12321 is larger. This can be adapted by the person skilled in the art.

In a specific embodiment, as shown in fig. 1, 7-9, a sliding groove 114 and a through groove 115 penetrating to the accommodating cavity are formed on the surface of the housing 11, the sliding groove 114 extends along the radial direction of the fixing shaft 111, and one end of the sliding groove 114 away from the fixing shaft 111 is communicated with the through groove 115; the pawl 15 includes a sliding portion 151 and a bending portion 152, the sliding portion 151 is elastically slidably connected in the sliding slot 114, the bending portion 152 is connected to one end of the sliding portion 151 away from the fixing shaft 111, the bending portion 152 passes through the through slot 115 and is bent into the accommodating cavity, and the bending portion 152 is used for abutting against the ratchet 12321 of the ratchet 1232 when the winding member 12 rotates reversely, so as to limit the release of the elastic member 13.

Specifically, when the winding member 12 rotates in the forward direction (X direction in fig. 1), the bending portion 152 always moves along the outer peripheral surface of the ratchet 1232, and the earphone cord is not prevented from being pulled out freely, because the sliding portion 151 is elastically disposed on the sliding groove 114, the sliding portion 151 can drive the bending portion 152, so as to ensure that the bending portion 152 can also be attached to the outer peripheral surface of the ratchet 1232 under the action of elastic force when the ratchet 1232 rotates. However, when the wire winding member 12 rotates reversely (Y direction in fig. 1) until the pawl 15 abuts against the ratchet 12321 of the ratchet 1232, the pawl 15 will catch the ratchet 1232, thereby limiting the release of the elastic member 13, so that the stretched earphone wire will not be retracted into the storage box of the earphone 100. However, when the wire winding member 12 rotates reversely (Y direction in fig. 1) until the bending portion 152 abuts against the ratchet 12321 of the ratchet 1232, the bending portion 152 will block the ratchet 1232, so as to limit the release of the elastic member 13, and the stretched earphone cord will not be retracted into the storage box of the earphone 100. When the earphone cord needs to be completely retracted, the sliding portion 151 is only required to be pushed in a direction away from the fixing shaft 111, so that the sliding portion 151 drives the bending portion 152 to be separated from the ratchet 12321, and at this time, the winding element 12 is separated from the limitation of the bending portion 152, and will rotate reversely under the driving of the elastic element 13 until the earphone cord is completely retracted. In the embodiment, the pawls 15 are received in the sliding slots 114 and the through slots 115 of the housing 11, so that the earphone storage box 10 has a smaller overall size, and therefore, the earphone storage box 10 is smaller in overall size and is convenient to carry.

In this embodiment, when the sliding portion 151 slides in a direction away from the mounting shaft, the elastic band is gradually stretched, so that the sliding portion 151 is forced toward the elastic band mounting portion, thereby ensuring that the bending portion 152 can always adhere to the outer peripheral surface of the ratchet 1232 under the elastic force when the ratchet 1232 rotates.

In another embodiment, as shown in fig. 1 and 7-10, a first mounting protrusion 116 and a second mounting protrusion 117 are further disposed on the surface of the housing 11 and spaced from the sliding slot 114 along the first direction, the first mounting protrusion 116 is located between the sliding slot 114 and the second mounting protrusion 117, the earphone wire storage box 10 further includes a torsion spring 16, the middle of the torsion spring 16 is sleeved on the first mounting protrusion 116, and two ends of the torsion spring 16 are respectively mounted on the second mounting protrusion 117 and the sliding portion 151. Wherein, the first direction and the extending direction of the sliding chute 114 form an included angle.

In this embodiment, when the sliding portion 151 slides in a direction away from the mounting shaft, the middle portion of the torsion spring 16 deforms, such that the end of the torsion spring 16 mounted on the sliding portion 151 moves along with the sliding portion 151, and the torsion spring 16 deforms to generate a stress therein, so as to ensure that the bending portion 152 can always adhere to the outer peripheral surface of the ratchet 1232 under the action of the elastic force when the ratchet 1232 rotates.

In an embodiment, as shown in fig. 1 and 2, the elastic member 13 is a clockwork spring, the winding member 12 is provided with a third mounting protrusion 124 spaced apart from the mounting hole 121, and a mounting groove 1111 is formed on the fixing shaft 111 along a radial direction of the fixing shaft 111; spring one end is installed on third installation arch 124, and the other end is installed in mounting groove 1111.

Specifically, the spiral spring is a spring formed by winding a material into a planar spiral shape, one end of the spring is fixed, and after a torque is applied to the other end of the spring, the material is subjected to bending moment to generate bending elastic deformation, so that the spring generates torsion on the plane of the spring. The deformation angle is proportional to the torque, and has the characteristics of high torque and low fatigue.
