Patent Description:
Existing TWS (true wireless stereo) earphones are mainly classified into two types: earphones with a bud shape and earphones with a stem shape. The earphone is in contact with and compresses a pogopin (also referred to as pogo pin) in an earphone box by a copper column on the earphone when it is placed into the earphone box, to realize a charging process of the earphone by the earphone box. Ensuring that the copper column of the earphone is in full contact with the pogopin of the earphone box to realize the charging of the earphone when the earphone is placed into the earphone box, is typically implemented as follows: an inner housing of the earphone box has a shape similar to a shape of the earphone; a position of the earphone in the earphone box is restricted by the shape; moreover, in order to ensure the charging reliability of the placed earphone, the copper column of the earphone and the pogopin of the earphone charging box are both oriented along a vertical direction, which is consistent with the gravity direction of the earphone, to reduce a mutual dislocation between the copper column and the pogopin caused by the gravity component.

Embodiments of the present invention are described in detail below, and examples of the described embodiments are illustrated in accompanying drawings. The following embodiments described with reference to the accompanying drawings are exemplary and are intended to explain the present invention, rather than limit the present invention.

The earphone box in the related art has the disadvantages of a low utilization rate of an internal space, a large overall volume and inconvenient carrying, and it is inconvenient to take the earphone out of the earphone box.

An earphone box <NUM> according to embodiments of the present invention is described below with reference to the accompanying drawings.

As illustrated in <FIG>, the earphone box <NUM> according to embodiments of the present invention includes a box body <NUM> and a box magnet <NUM>.

The box body <NUM> defines an accommodating groove <NUM> for accommodating an earphone <NUM>, and the accommodating groove <NUM> is provided with an interface <NUM> electrically coupled to the earphone <NUM>.

The box magnet <NUM> is mounted on the box body <NUM>, and is configured as a multipole magnet. The box magnet <NUM> is a planar multipole magnet, i.e., an attraction face of the box magnet <NUM> has at least one pair of poles (one N pole and one S pole). The earphone <NUM> is provided with an earphone magnet <NUM> with the same number of poles as the box magnet <NUM>. Therefore, an attraction face of the earphone magnet <NUM> also has at least one pair of poles. Moreover, a number of poles of the earphone magnet <NUM> and a number of poles of the box magnet <NUM> are the same. That is, when the box magnet <NUM> is a four-pole magnet, the earphone magnet <NUM> is also a four-pole magnet; when the box magnet <NUM> is a two-pole magnet, the earphone magnet <NUM> is also a two-pole magnet. The earphone magnet <NUM> attracts and couples with the box magnet <NUM>, so that the earphone <NUM> can be fixed in the accommodating groove <NUM> and arranged obliquely relative to the box body <NUM>, e.g., obliquely relative to a plane defined by the left-right direction and by the front-rear direction of the earphone box <NUM>, and/or obliquely relative to a plane defined by the up-down direction and by the front-rear direction of the earphone box <NUM>.

An earphone box in the related art has following disadvantages: a low utilization rate of an internal space, a large overall volume and the inconvenient carrying, and the earphone is inconvenient to take out of the earphone box.

In the earphone box <NUM> according to embodiments of the present invention, since the box body <NUM> is provided with the box magnet <NUM> configured as the multipole magnet and the earphone <NUM> is provided with the earphone magnet <NUM> with the same number of poles as the box magnet <NUM>, the attraction face of the box magnet <NUM> has at least one pair of poles, and the attraction face of the earphone magnet <NUM> also has at least one pair of poles. Moreover, the earphone magnet <NUM> attracts and couples with the box magnet <NUM>, so that a plurality of poles on the attraction face of the earphone magnet <NUM> and a plurality of poles on the attraction face of the box magnet <NUM> attract each other together in a one-to-one correspondence, thereby realizing a multi-point positioning (at least two-point positioning) of the earphone <NUM> and the accommodating groove <NUM>, so that the positioning effect between the earphone magnet <NUM> and the box magnet <NUM> is better or improved over conventional approaches. Moreover, the earphone magnet <NUM> and the box magnet <NUM> are the multipole magnet, thereby increasing an attraction force between the earphone magnet <NUM> and the box magnet <NUM>, so that the positioning effect between the earphone magnet <NUM> and the box magnet <NUM> is further improved.

The box magnet <NUM> is mounted on the box body <NUM>, and the earphone magnet <NUM> is arranged on the earphone <NUM>. Therefore, the positioning between the earphone <NUM> and box body <NUM> changes from the traditional single-point positioning to the multi-point positioning (at least two-point positioning) through a multi-point attraction cooperation between the earphone magnet <NUM> and the box magnet <NUM>, thus increasing the positioning effect between the earphone <NUM> and the box body <NUM>, so that the earphone <NUM> is more stable and not easy to change its position when it is attracted on the box body <NUM>. Thus, the earphone <NUM> is more stable when charging in the box body <NUM>, and the charging effect is better or improved over conventional approaches.

The improved positioning effect between the earphone <NUM> and the box body <NUM> can avoid the charging instability of the earphone <NUM> caused by the gravity. Thus, a placement mode of the earphone <NUM> does not have to be limited to a mode of a horizontal placement and a mode of a vertical placement, so that the earphone <NUM> can be fixed in the accommodating groove <NUM> conveniently and arranged obliquely relative to the box body <NUM>. Since the earphone has a generally strip structure, the mode of the horizontal placement will waste space and increase a length of the box body, the mode of the vertical placement will also waste space and increase a height of the box body. The increase in each of the length, the width and the height of the box body will increase a volume of the box body. However, when the earphone <NUM> is arranged obliquely relative to the box body <NUM>, a space of the box body <NUM> can be fully used, i.e., the space utilization rate of the box body <NUM> is improved, thereby reducing the length or the height of the box body <NUM>, which is conducive to reducing the volume of the box body <NUM>, i.e., a volume of the earphone box <NUM> becomes small and easy to carry.

Therefore, the earphone box <NUM> according to embodiments of the present invention, when compared to conventional approaches, has the advantages of providing the improved positioning effect, the stable charging, the small volume and the good or improved portability.

For convenience of understanding, an up-down direction of the earphone box <NUM> according to embodiments of the present invention is illustrated by an arrow A in <FIG>, a left-right direction of the earphone box <NUM> according to embodiments of the present invention is illustrated by an arrow B in <FIG>, and a front-rear direction of the earphone box <NUM> according to embodiments of the present invention is illustrated by an arrow C in <FIG>.

As illustrated in <FIG>, the earphone box <NUM> according to embodiments of the present invention includes the box body <NUM>, the box cover <NUM> and the box magnet <NUM>.

As illustrated in <FIG>, the box body <NUM> defines the accommodating groove <NUM> for accommodating the earphone <NUM>, and the accommodating groove <NUM> is provided with the interface <NUM> electrically coupled to the earphone <NUM>. That is, the earphone <NUM> can be placed in the accommodating groove <NUM> and electrically coupled to the interface <NUM>, to charge the earphone <NUM>.

The box cover <NUM> is pivotally coupled to the box body <NUM>, to open and close the accommodating groove <NUM>. That is, the box cover <NUM> and the box body <NUM> can rotate with respect to each other. For example, the box body <NUM> is located below the box cover <NUM> in the up-down direction. A rear end of the box body <NUM> is coupled to a rear end of the box cover <NUM>. Therefore, when a front end of the box cover <NUM> rotates upward around a joint between the box cover <NUM> and the box body <NUM>, the accommodating groove <NUM> can be opened and the earphone <NUM> can be put in or taken out. When the front end of the box cover <NUM> rotates downward around the joint between the box cover <NUM> and the box body <NUM>, the accommodating groove <NUM> can be closed.

The box magnet <NUM> is mounted on the box body <NUM>, and is configured as the multipole magnet. The earphone <NUM> is provided with the earphone magnet <NUM> with the same number of poles as the box magnet <NUM>. Thus, the earphone <NUM> can be fixed on the box body <NUM> by the multi-point positioning conveniently.

In some embodiments, each of the box magnet <NUM> and the earphone magnet <NUM> is a two-pole magnet. The two-pole magnet has a small volume, is convenient to mount and reduces the volume of the box body <NUM>. Moreover, the two-point positioning between the box magnet <NUM> and the earphone magnet <NUM> is realized by the two-pole magnet, to improve the positioning effect between the earphone <NUM> and the box body <NUM>. Specifically, two poles on the attraction face of the earphone magnet <NUM> of the two-pole magnet and two poles on the attraction face of the box magnet <NUM> of the two-pole magnet attract each other together correspondingly, to realize the two-point positioning effect, so that the positioning effect between the earphone magnet <NUM> and the box magnet <NUM> is good or improved. Moreover, the earphone magnet <NUM> and the box magnet <NUM> are two-pole magnets, to increase the attraction force between the earphone magnet <NUM> and the box magnet <NUM>, so that the positioning effect between the earphone magnet <NUM> and the box magnet <NUM> is further improved. That is, the positioning effect between the earphone <NUM> and the box body <NUM> is improved, so that the earphone <NUM> is more stable and not easy to change its position when it is attracted on the box body <NUM>. Thus, the earphone <NUM> is more stable when charging in the box body <NUM>, and the charging effect is good or improved.

The earphone magnet <NUM> of the two-pole magnet and the box magnet <NUM> of the two-pole magnet have a strong attraction force and a good positioning effect, so that the movement and a charging instability of the earphone <NUM> caused by the gravity can be avoided. Thus the placement mode of the earphone <NUM> does not have to be limited to the mode of the horizontal placement and the mode of the vertical placement, so that the earphone <NUM> can be fixed in the accommodating groove <NUM> conveniently and arranged obliquely relative to the box body <NUM>.

In some embodiments, the accommodating groove <NUM> includes a left accommodating groove <NUM> for accommodating a left earphone and a right accommodating groove <NUM> for accommodating a right earphone. Specifically, the left accommodating groove <NUM> is located at a left portion of the box body <NUM>, and the right accommodating groove <NUM> is located at a right portion of the box body <NUM>. The left accommodating groove <NUM> and the right accommodating groove <NUM> are arranged symmetrically in a mirrored manner in the left-right direction, to effectively use the space of the box body <NUM>, improve the space utilization rate of the box body <NUM>, which is conducive to reducing the volume of the box body <NUM>, so that the earphone box <NUM> has a small volume and is easy to carry.

As illustrated in <FIG> and <FIG>, in some embodiments, the box magnet <NUM> includes a first box magnet <NUM> and a second box magnet <NUM> arranged in the box body <NUM>. At least part of the first box magnet <NUM> is exposed in the left accommodating groove <NUM>, and at least part of the second box magnet <NUM> is exposed in the right accommodating groove <NUM>. An exposed face (an attraction face) of at least a part of the first box magnet <NUM> has a plurality of poles, and an exposed face (the attraction face) of at least a part of the second box magnet <NUM> has a plurality of poles.

The exposed face of the first box magnet <NUM> can directly attract the earphone magnet <NUM> of the left earphone in the left accommodating groove <NUM> and has a plurality of positioning points (at least two), and the first box magnet <NUM> can be in direct contact with the earphone magnet <NUM> of the left earphone in the left accommodating groove <NUM> without a barrier layer, so that the attraction effect between the first box magnet <NUM> and the earphone magnet <NUM> of the left earphone in the left accommodating groove <NUM> can be improved. That is, the left earphone is fixed more stably, and the charging is stable.

Similarly, the exposed face of the second box magnet <NUM> can directly attract the earphone magnet <NUM> of the right earphone in the right accommodating groove <NUM> and has a plurality of positioning points (at least two), and the second box magnet <NUM> can be in direct contact with the earphone magnet <NUM> of the right earphone in the right accommodating groove <NUM> without the barrier layer, so that the attraction effect between the second box magnet <NUM> and the right earphone in the right accommodating groove <NUM> is improved. That is, the right earphone is fixed more stably, and the charging is stable.

As illustrated in <FIG>, in some embodiments, the box body <NUM> includes a first inclined face <NUM> constituting at least part of a side wall of the left accommodating groove <NUM> and a second inclined face <NUM> constituting at least part of a side wall of the right accommodating groove <NUM>. The first inclined face <NUM> allows the left earphone to be placed obliquely in the left accommodating groove <NUM>, and the second inclined face <NUM> allows the right earphone to be placed obliquely in the right accommodating groove <NUM>, to improve the utilization rate of the space of the box body <NUM>, which is conducive to reducing the volume of the box body <NUM>, so that box body <NUM> is easy to carry.

The first box magnet <NUM> is arranged on the first inclined face <NUM> with an outer surface <NUM> of the first box magnet <NUM> being flush with the first inclined face <NUM>. That is, the outer surface <NUM> (the attraction face) of the first box magnet <NUM> and the first inclined face <NUM> are on the same plane, so that the left earphone can be placed and positioned in the left accommodating groove <NUM> conveniently. The second box magnet <NUM> is arranged on the second inclined face <NUM> with an outer surface <NUM> of the second box magnet <NUM> being flush with the second inclined face <NUM>. That is, the outer surface <NUM> (the attraction face) of the second box magnet <NUM> and the second inclined face <NUM> are on the same plane, so that the right earphone can be placed and positioned in the right accommodating groove <NUM> conveniently.

In some embodiments, a polarity distribution at the outer surface <NUM> of the first box magnet <NUM> is different from a polarity distribution at the outer surface <NUM> of the second box magnet <NUM>. For example, when an upper portion of the outer surface <NUM> of the first box magnet <NUM> is N pole and an lower portion thereof is S pole, an upper portion of the outer surface <NUM> of the second box magnet <NUM> is S pole and an lower portion thereof is N pole, or, when a left portion of the outer surface <NUM> of the first box magnet <NUM> is N pole and a right portion thereof is S pole, a left portion of the outer surface <NUM> of the second box magnet <NUM> is S pole and a right portion thereof is N pole. Thus, it is difficult to place the left earphone in the right accommodating groove <NUM> or to place the right earphone in the left accommodating groove <NUM>, thereby facilitating the correct positioning and the placement of the left earphone and the right earphone.

As illustrated in <FIG> and <FIG>, in some embodiments, the interface <NUM> includes a left interface <NUM> arranged in the left accommodating groove <NUM> and a right interface <NUM> arranged in the right accommodating groove <NUM>. The left interface <NUM> may be electrically coupled to the left earphone, to charge the left earphone, and the right interface <NUM> may be electrically coupled to the right earphone, to charge the right earphone.

An axis perpendicular to a surface of the left interface <NUM> (also referred to as the axis of the left interface <NUM>) and an axis perpendicular to a surface of the right interface <NUM> (also referred to as the axis of the right interface <NUM>) are arranged obliquely. That is, the axis of the left interface <NUM> can be arranged obliquely relative to the up-down direction. For example, the axis of the left interface <NUM> can be substantially perpendicular to the first inclined face <NUM>, to facilitate an electrical coupling between the left earphone and the left interface <NUM>, i.e., to facilitate the left interface <NUM> to stably charge the left earphone. The axis of the right interface <NUM> can be arranged obliquely relative to the up-down direction, and the axis of the right interface <NUM> can be substantially perpendicular to the second inclined face <NUM>, to facilitate an electrical coupling between the right earphone and the right interface <NUM>, i.e., to facilitate the right interface <NUM> to stably charge the right earphone.

In some embodiments, an angle included between the axis of each of the left interface <NUM> and the right interface <NUM> and a plane defined by the left-right direction and by the front-rear direction of the earphone box <NUM> (e.g., the horizontal plane when the earphone box is positioned as illustrated in the figures) is <NUM>°-<NUM>°. In this angle range, the box body <NUM> has a smaller volume and is easy to carry while facilitating the left interface <NUM>/the right interface <NUM> to stably charge the left earphone/the right earphone.

As illustrated in <FIG> and <FIG>, in some embodiments, the left interface <NUM> is arranged on the first inclined face <NUM> and adjacent to the first box magnet <NUM>. Therefore, after the left earphone enters into the left accommodating groove <NUM>, it can be electrically coupled to the left interface <NUM> conveniently. Moreover, a position between the first box magnet <NUM> of the left earphone and the earphone magnet <NUM> of the left earphone has a strong attraction force, thus realizing the good positioning effect. The left interface <NUM> is adjacent to the first box magnet <NUM>, so that the left earphone and the left interface <NUM> are coupled stably, i.e., the charging of the left earphone is more stable.

The right interface <NUM> is arranged on the second inclined face <NUM> and adjacent to the second box magnet <NUM>. Therefore, after the right earphone enters into the right accommodating groove <NUM>, it can be electrically coupled to the right interface <NUM> conveniently. Moreover, a position between the second box magnet <NUM> of the right earphone and the earphone magnet <NUM> of the right earphone has a strong attraction force, thus realizing the good positioning effect. The right interface <NUM> is adjacent to the second box magnet <NUM>, so that the right earphone and the right interface <NUM> are coupled stably, i.e., the charging of the right earphone is more stable.

As illustrated in <FIG> and <FIG>, in some embodiments, each of the left interface <NUM> and the right interface <NUM> is a pogopin, and the left earphone and the right earphone are each provided with a coupling copper column for abutting with a spring pin <NUM> of pogopin. For example, in each of the left interface <NUM> and the right interface <NUM>, two spring pins <NUM> of pogopin are provided, and located at two sides of the box magnet <NUM>. That is, the left interface <NUM> includes two spring pins <NUM> of pogopin, and the two spring pins <NUM> of pogopin of the left interface <NUM> are located at two opposite sides of the first box magnet <NUM>; and the right interface <NUM> includes two spring pins <NUM> of pogopin, and the two spring pins <NUM> of pogopin of the right interface <NUM> are located at two opposite sides of the second box magnet <NUM>. When the left earphone is placed in the left accommodating groove <NUM>, the coupling copper columns of the left earphone press the spring pins <NUM> of the left interface <NUM>, to create the electrical coupling between the left earphone and the left interface <NUM>, so that the charging of the left earphone is stable. When the right earphone is placed in the right accommodating groove <NUM>, the coupling copper columns of the right earphone press the spring pins <NUM> of the right interface <NUM>, to create the electrical coupling between the right earphone and the right interface <NUM>, so that the charging of the right earphone is stable.

In some embodiments, each of the first inclined face <NUM> and the second inclined face <NUM> is a frosted face. Therefore, when the left earphone is placed on the first inclined face <NUM>, a friction is large, so that the left earphone is not easy to move and the positioning effect is good. When the right earphone is placed on the second inclined face <NUM>, a friction is large, so that the right earphone is not easy to move and the positioning effect is good. The first box magnet <NUM> and the left interface <NUM> are arranged on the first inclined face <NUM> with the frosted face, so that the left earphone can be fixed and electrically coupled only by contacting the first inclined face <NUM>. Thus, the left earphone can be arranged obliquely, maximizing utilization rate of the space of the box body <NUM> and reducing the volume of the box body <NUM>. Moreover, the left accommodating groove <NUM> is according to the invention not to be limited to the profile of the earphone thereby realizing the reliability of charging also when the earphone is fitted with different shapes of different specifications of ear caps or sleeves. The second box magnet <NUM> and the right interface <NUM> are arranged on the second inclined face <NUM> with the frosted face, so that the right earphone can be fixed and electrically coupled only by contacting the second inclined face <NUM>. Thus, the right earphone can be arranged obliquely, maximizing utilization rate of the space of the box body <NUM> and reducing the volume of the box body <NUM>. Moreover, the right accommodating groove <NUM> does not have be limited to the profile of the earphone thereby realizing the reliability of charging also when the earphone is fitted with different shapes of different specifications of ear caps or sleeves.

As illustrated in <FIG>, in some embodiments, the first inclined face <NUM> is inclined towards the right accommodating groove <NUM>, so that the left earphone accommodated in the left accommodating groove <NUM> faces towards the right accommodating groove <NUM>. The second inclined face <NUM> is inclined towards the left accommodating groove <NUM>, so that the right earphone accommodated in the right accommodating groove <NUM> is inclined towards the left accommodating groove <NUM>. Thus, positions of the first box magnet <NUM> and the left interface <NUM> and positions of the second box magnet <NUM> and the right interface <NUM> are close, and all accommodated in a space, to make full use of the space of the box body <NUM> and reduce the volume of the box body <NUM>.

As illustrated in <FIG> and <FIG>, in some embodiments, the box body <NUM> further includes a lower mounting cavity <NUM> spaced apart from the accommodating groove <NUM>, the box cover <NUM> defines an upper mounting cavity <NUM>, the lower mounting cavity <NUM> is provided with a Hall sensor <NUM>, and the upper mounting cavity <NUM> is provided with a Hall magnet <NUM>. Specifically, the lower mounting cavity <NUM> is located below the accommodating groove <NUM>, and the upper mounting cavity <NUM> is located above the accommodating groove <NUM>. The Hall sensor <NUM> in the lower mounting cavity <NUM> can cooperate with the Hall magnet <NUM> in the upper mounting cavity <NUM> using the Hall effect. When the box cover <NUM> is opened, i.e., when the accommodating groove <NUM> is opened, the Hall sensor <NUM> detects information and sends the information to the earphone <NUM>, so that a Bluetooth of the earphone <NUM> is turned on and the earphone <NUM> is automatically paired with the mobile phone.

In some embodiments, the upper mounting cavity <NUM> is provided with a first attraction magnet <NUM>, the lower mounting cavity <NUM> is provided with a second attraction magnet <NUM>, and the second attraction magnet <NUM> is configured to attract and couple with the first attraction magnet <NUM> when the box cover <NUM> closes the accommodating groove. Thus, when the box cover <NUM> is closed, a coupling between the box body <NUM> and the box cover <NUM> is strengthened, thus preventing the box cover <NUM> from being opened by mistake and preventing the earphone <NUM> from being lost.

The earphone <NUM> according to the present invention includes an earphone body <NUM> configured as a bud shape, and the earphone body <NUM> is adapted to fit in the accommodating groove <NUM> of the earphone box <NUM> according to any one of the above embodiments.

The earphone <NUM> according to embodiments of the present invention can be obliquely placed in the accommodating groove <NUM> in the earphone box <NUM>, has a good positioning effect and can be charged stably. Moreover, after the earphone <NUM> is placed in the accommodating groove <NUM>, the overall volume is small and the earphone <NUM> is easy to carry.

In some embodiments, the earphone <NUM> further includes a plurality of earphone caps or sleeves <NUM> of different specifications. Each of the plurality of earphone sleeves <NUM> is adapted to be fitted over the earphone body <NUM>, and the earphone body <NUM> fitted with any earphone sleeve <NUM> can fit in the accommodating groove <NUM>.

That is, a space of the accommodating groove <NUM> is larger than a total volume of the earphone body <NUM> and the earphone sleeve <NUM> fitted over a side of the earphone body <NUM>. The earphone <NUM> can be put into the accommodating groove <NUM> for charging and storage without removing the earphone sleeve <NUM>. The earphone box <NUM> has a strong adaptability.
