Description

Battery and earphone with battery

Technical Field

Background

The wireless Bluetooth headset on the market at present supplies power through a cylindrical button-shaped battery. The button cell has two main processes, one is a pole piece winding process, and the other is a pole piece lamination process. The pole piece lamination process battery has the advantages of complex structure and process, high manufacturing cost and low volume energy ratio. The battery of the pole piece winding process is simple in structure and high in volume capacity ratio, and is popular in earphone terminal factories and battery factories. Because the positive and negative electrode sheets of the wound battery are arranged in a spiral shape, an alternating magnetic field can be generated in the charging and discharging process. The alternating magnetic field that produces can produce the coupling with the magnetic field that the coil produced in the earphone, has influenced the sound production performance of earphone, and then has influenced user and has used experience.

In order to reduce the coupling phenomenon between the battery and the coil in the earphone, a connecting sheet can be added on the end face of the battery to counteract the magnetic flux leakage phenomenon of the battery core.

In order to improve the user experience and enable the user to obtain more frequency sound quality, the magnetic flux of the left earphone and the magnetic flux of the right earphone are often set to be different. However, the same type of battery can not be applied to different earphones at present, so that the production difficulty of the battery is increased, and the production efficiency of the battery is reduced.

Detailed Description

Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that: the relative arrangement of the components and steps, the numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present disclosure unless specifically stated otherwise.

The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses.

Techniques and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail, but are intended to be considered a part of the specification where appropriate.

In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

According to one embodiment of the present disclosure, a battery is provided. Referring to fig. 1 to 10, the battery includes: a battery cell 1 and a first connecting member 21. The battery cell 1 comprises a first pole, a diaphragm and a second pole piece which are stacked and then wound together, wherein the length of the first pole piece is different from that of the second pole piece. The first connecting piece 21 is of an arc-shaped structure, the first connecting piece 21 is provided with a first end 211 and a second end 212 which are opposite to each other, the first end 211 is electrically connected with the first pole piece, the direction from the first end to the second end is defined as a first extending direction, and at least two first output ends are arranged at intervals along the first extending direction of the first connecting piece 21.

It should be noted that the "end" of the first connecting element does not refer to the end point of the first connecting element. In this embodiment "end" refers to a local area of the first connection element. The "first end of the first connecting member 21" and the "second end of the first connecting member 21" refer to two different local areas on the first connecting member.

In other words, the battery mainly includes the battery cell 1 and the first connection member 21. The battery cell 1 is a winding battery cell. The battery cell comprises a first pole piece, a diaphragm and a second pole piece, wherein the diaphragm is positioned between the first pole piece and the second pole piece, and the first pole piece, the diaphragm and the second pole piece are mutually stacked and jointly wound to form the battery cell 1. For example, the first pole piece may be a positive pole piece and the second pole piece may be a negative pole piece or the first pole piece may be a negative pole piece and the second pole piece may be a positive pole piece.

In this embodiment, the length of the first pole piece is different from the length of the second pole piece. In other words, during the winding process of the battery cell 1, the first pole piece is wound one more section relative to the second pole piece or the first pole piece is wound one less section relative to the second pole piece. And in the use process of the battery, the current direction of the wound first pole piece is opposite to the current direction of the wound second pole piece. For example, the current direction of the first pole piece is clockwise, and the current direction of the second pole piece is counterclockwise; or the current direction of the first pole piece is anticlockwise, and the current direction of the second pole piece is clockwise. During the use process of the battery, the first pole piece can generate a first magnetic field. The second pole piece generates a second magnetic field. Because the current direction of the first pole piece is opposite to the current direction of the second pole piece, the first magnetic field and the second magnetic field can be mutually counteracted, but the length of the first pole piece is different from that of the second pole piece. According to the correlation between the magnetic flux of the electrified conductor and the length of the conductor, a first magnetic field generated by the current in the first pole piece and a second magnetic field generated by the current in the second pole piece cannot be completely counteracted, and the electric core still generates the magnetic leakage flux (partial magnetic field is not completely counteracted) phenomenon in the use process of the battery. If the leakage flux phenomenon generated by the battery core is not improved, when the battery is applied to the electronic equipment, the magnetic field generated by the battery and the magnetic field generated by the coil of the electronic equipment are coupled to influence the normal use of the electronic equipment.

In order to solve the magnetic flux leakage phenomenon generated by the battery cell, a first connection sheet 21 is provided on the battery cell 1. The first connection member 21 is connected between the battery cell 1 and an external load. The first connecting member 21 is electrically connected to the battery cell 1, and a current is generated in the first connecting member 21. The magnetic field generated by the current flowing through the first connection member 21 cancels out the magnetic field generated by the battery cell 1. Specifically, the magnetic field generated by the first connection piece 21 and the magnetic field not cancelled inside the battery cell 1 may cancel each other, so as to avoid the magnetic field generated by the battery cell 1 from affecting the use of the electronic device.

But the magnetic flux requirements are not consistent from electronic device to electronic device. The electronic device is for example a headset. The requirements for the earphone flux are not the same in order to obtain sound quality at different frequencies. The strong and weak that the strong magnet in the earphone will be fine control sound and send, magnetism is big more, and the inside vibration of the cavity of earphone is just big more, and sound will be loud more, and on the contrary, magnetism is little, and the inside vibration of cavity also can diminish, and sound also can reduce to some extent, but can remain better tone quality. However, the current connecting sheet structure cannot meet the requirement of different electronic devices on magnetic flux.

In order to solve the above technical problem, the first connecting piece 21 structure is specially designed in the present embodiment to meet the requirements of different electronic devices for magnetic flux.

The first connecting member 21 is connected to the first pole piece. The first pole piece can be a positive pole piece or a negative pole piece.

The first connecting member 21 has an arc-shaped configuration. According to the principle that magnetic fields counteract each other: when the magnetic fields are equal in magnitude and opposite in direction, the magnetic fields can cancel each other out. Because the battery cell 1 is a winding battery cell, in order to enable the magnetic field generated by the first connecting member 21 to better perform a magnetic field with the magnetic field inside the battery cell 1 for cancellation, the embodiment sets the first connecting member 21 to have an arc-shaped structure.

The first connecting member 21 has a first end 211 and a second end 212 opposite to each other, the first end 211 is electrically connected to the first pole piece, and a direction in which the first end extends to the second end is defined as a first extending direction, as shown in fig. 1, and an arrow a indicates the first extending direction.

The first connecting member 21 is provided with at least two first output ends 213 at intervals along the first extending direction. Specifically, the present embodiment is provided with at least two first output ends 213 at intervals in the first extending direction of the first connecting member 21. Referring to fig. 1 to 10, in the present example, two first output terminals 213 are disposed in the first extending direction of the first connecting member 21, and the two first output terminals 213 include a first output terminal 213a and a first output terminal 213 b. The first output terminal 213a and the first output terminal 213b are spaced apart. Therefore, along the first extending direction of the first connecting member 21 (i.e. the circumferential direction of the first connecting member), the arc length from the first end 211 of the first connecting member 21 to the first output end 213a is different from the arc length from the first end 211 of the first connecting member 21 to the first output end 213 b. When an external load is connected to different first output terminals 213 to draw out a current, the magnitude of the magnetic field generated by the first connection member 21 itself is different. The magnitude of the magnetic field generated by the energized conductor is related to the length of the conductor. When the current is the same, the external load is connected to the first output terminal 213a, and the magnetic field generated by the first connection element 21 is larger than the magnetic field generated when the external load is connected to the second output terminal 213 b.

Different first output terminals 213 can thus be selectively connected according to the magnetic flux requirements of the external load. Through connecting different first output ends and outwards outputting electric energy, the magnetic field generated by the current on the first connecting sheet 21 offsets different external loads and the magnetic field generated by the winding battery cell, and the influence of the magnetic field generated inside the battery cell 1 on the normal use of the external loads is avoided.

In one embodiment, referring to fig. 1, 3, 5, 7 and 9, in the case that the length of the first pole piece is longer than the length of the second pole piece, the first extending direction of the first connector 21 is opposite to the winding direction of the first pole piece.

In the case where the first pole piece length is shorter than the second pole piece length, the first extending direction of the first connector 21 is the same as the winding direction of the first pole piece.

Specifically, along the first extending direction of the arc-shaped structure of the first connecting member 21, the first connecting member 21 has a first end 211 and a second end 212. For example, the direction indicated by the arrow a is the first extending direction of the first connecting member 21. The first output terminal 213 is disposed near the second end 212 of the first connecting member 21, and the current direction of the first connecting member 21 is the same as the first extending direction of the first connecting member 21.

In the case where the first pole piece is longer than the second pole piece, a portion of the magnetic field generated by the current in the first pole piece cannot be cancelled by the magnetic field generated by the current in the second pole piece. In order to cancel the magnetic field that is not cancelled in the first pole piece, the first extending direction of the first connecting piece 21 needs to be opposite to the winding direction of the first pole piece.

The first extending direction of the first connection member 21 coincides with the current direction of the first connection member 21. The winding direction of the first pole piece is consistent with the current direction in the first pole piece. That is, in the case that the first extending direction of the first connector 21 is opposite to the winding direction of the first pole piece, the current direction of the first connector 21 is opposite to the current direction in the first pole piece. The magnetic field generated by the battery in the first connecting piece 21 can be offset with the magnetic field which is not offset in the first pole piece, so that the influence of the magnetic field generated in the battery core on the normal use of an external load is avoided.

In the case where the length of the first pole piece is shorter than the length of the second pole piece, a portion of the magnetic field generated by the current in the second pole piece cannot be cancelled by the magnetic field generated by the current in the first pole piece. In order to cancel the magnetic field that is not cancelled in the second pole piece, the first extending direction of the first connecting piece 21 needs to be the same as the winding direction of the first pole piece. The first extending direction of the first connection member 21 coincides with the current direction of the first connection member 21. The winding direction of the first pole piece is consistent with the current direction in the first pole piece. Therefore, in the case that the first extending direction of the first connecting member 21 is the same as the winding direction of the first pole piece, the current direction of the first connecting member 21 is opposite to the battery direction in the second pole piece. The magnetic field generated by the battery in the first connecting piece 21 can be offset with the magnetic field which is not offset in the second pole piece, so that the influence of the magnetic field generated inside the battery core 1 on the normal use of an external load is avoided.

In one embodiment, referring to fig. 2, 4, 6, 8 and 10, the first connector 21 is disposed on an end surface of the battery cell 1, and the first connector 21 is disposed coaxially with the battery cell 1.

Specifically, the first connection member 21 has substantially the same winding curvature as that of the winding of the battery cell 1 and is disposed substantially coaxially with the winding battery cell, so that the magnetic field generated by the current in the first connection member 21 can better cancel each other out with the magnetic field generated by the current in the first pole piece or with the magnetic field generated by the current in the second pole piece. Optionally, the first connecting member 21 is disposed on the end face of the battery cell 1, and the curvature of the first connecting member 21 is the same as the winding curvature of the battery cell and is disposed coaxially with the winding battery cell.

Optionally, referring to fig. 1-10, the first connecting member 21 further includes a positioning portion 214. Wherein the positioning portion 214 is provided at the first end 211 of the first connecting member 21. The positioning portion 214 is used for connection with the battery cell, and provides connection reliability of the first connection member 21 with the battery cell 1.

In one embodiment, referring to fig. 1 to 10, the battery includes a second connection member 22, the second connection member 22 is electrically connected to the second pole piece, the second connection member 22 includes an arc connection portion 222, and at least one second output terminal 2223 is disposed on the arc connection portion 222 along a circumferential direction of the arc connection portion 222.

Specifically, the first connecting member 21 and the second connecting member 22 constitute the connecting member 2. Wherein the first connecting piece 21 is connected with the first pole piece, and the second connecting piece 22 is connected with the second pole piece. The polarity of the first connection member 21 is therefore the same as the polarity of the first pole piece. The polarity of the second connection 22 is the same as the polarity of the second pole piece.

At least one second output port 2223 is provided on the arc-shaped connection portion 222 of the second connection member 22. For example, referring to fig. 1-6, a second output 2223 is provided at the arcuate connecting portion 222. In case that different external loads are connected to different first outputs 2223, the different external loads are connected to the same second output 2223. Referring to fig. 8, the external load is electrically connected to the first output terminal 213a, while the electronic device is electrically connected to the second output terminal 2223. Referring to fig. 10, the external load is electrically connected to the first output terminal 213b, while the electronic device is electrically connected to the second output terminal 2223.

In one embodiment, a plurality of the second output ports 2223 are disposed on the arc-shaped connection portion 222, and in the case that an external load is connected to different second output ports 2223, the magnitude of the magnetic field generated by the second connection member 22 is different correspondingly.

The arc-shaped connection portion 222 of the second connection member 22 is provided with two second output ends 2223. Referring to fig. 7 to 10, the two second output terminals 2223 include a second output terminal 2223a and a second output terminal 2223 b. I.e., in case the magnetic flux requirements of the external load are different, the external load may be selectively connected to different second output ports 2223. For example, referring to fig. 4, the external load is electrically connected to the first output terminal 213a, while the external load is electrically connected to the second output terminal 2223 a. Referring to fig. 6, the external load is electrically connected to the first output terminal 213b, while the external load is electrically connected to the second output terminal 2223 b.

Therefore, different first output terminals 213 and different second output terminals 2223 can be selectively connected according to the requirement of the external load for the magnetic flux. In this embodiment, the magnetic fields generated by the first connecting piece 21 and the second connecting piece 22 and the electric core 1 are offset with each other, so that the magnetic fields generated by the current on the first connecting piece 21 and the magnetic fields generated by the current on the second connecting piece 22 are offset with the magnetic fields generated by different external loads and the wound electric core, the influence of the magnetic fields generated inside the electric core 1 on the normal use of the electronic device is avoided, and the requirement of the electronic device on the magnetic flux is met.

In one embodiment, referring to fig. 1, 3, 5, 7 and 9, the arc-shaped connection portion 222 has a first end 2221 and a second end 2222, and a direction in which the first end 2221 of the arc-shaped connection portion 222 extends to the second end 2222 of the arc-shaped connection portion 222 is defined as a second extending direction, and the first extending direction is opposite to the second extending direction.

Specifically, the arc-shaped connection portion 222 has a first end and a second end along a circumferential direction of the arc-shaped connection portion 222. For example, the direction indicated by the arrow b is the second extending direction of the arc-shaped connecting portion 222. The second output port 2223 is disposed near the second end 2222 of the arc-shaped connection portion 222, and the current flowing direction of the arc-shaped connection portion 222 is the same as the second extending direction of the arc-shaped connection portion 222.

Therefore, in the case that the first extending direction of the first connecting member 21 is opposite to the second extending direction of the arc-shaped connecting portion 222, the current flowing direction of the first connecting member 21 is opposite to the current flowing direction of the arc-shaped connecting portion 222. That is, the current direction of the first connecting member 21 is clockwise, and the current direction of the arc-shaped connecting portion 222 is counterclockwise. Or the current direction of the first connecting member 21 is counterclockwise and the current direction of the arc-shaped connecting portion 222 is clockwise. Different first output terminals 213 and different second output terminals 2223 can therefore be selectively connected according to the magnetic flux requirements of the electronic device. In this embodiment, the magnetic fields generated by the first connecting piece 21 and the second connecting piece 22 and the electric core 1 are offset with each other, so that the magnetic fields generated by the current on the first connecting piece 21 and the magnetic fields generated by the current on the second connecting piece 22 are offset with the magnetic fields generated by different external loads and the wound electric core, the influence of the magnetic fields generated inside the electric core 1 on the normal use of the electronic device is avoided, and the requirement of the electronic device on the magnetic flux is met.

In one embodiment, the first pole piece is electrically connected to the first connection tab 21 and the second pole piece is electrically connected to the second connection tab 22. The first connecting piece 21 and the second connecting piece 22 cooperate together to cancel out leakage magnetic flux inside the battery cell 1.

For example, in the case where the length of the first pole piece is longer than the length of the second pole piece, the first connection tab 21 and the second connection tab 22 cooperate to cancel the magnetic field of the first pole piece that is not cancelled by the second pole piece. For example, the current direction of the first connecting piece 21 is the same as the current direction of the second connecting piece 22, and the current direction of the first connecting piece 21 and the current direction of the second connecting piece 22 are both opposite to the current direction of the first pole piece. When the first pole piece length is longer than the second pole piece length by L, the sum of the extension length L1 of the first connecting piece 21 and the extension length L2 of the second connecting piece 22 is L. The first connecting piece 21 and the second connecting piece 22 cooperate to cancel the magnetic field of the first pole piece that is not cancelled by the second pole piece.

Or in the case that the length of the first pole piece is longer than that of the second pole piece, the current direction of the first pole piece is the same as that of the first connection piece 21. The second connection piece 22 has a current flow direction opposite to that of the first connection piece 21. At this time, the first pole piece length is longer than the second pole piece length by L, and the extension length of the first connection piece 21 is L1. The second web 22 extends for a length L1+ L. The first connecting piece 21 and the second connecting piece 22 cooperate to cancel the magnetic field of the first pole piece that is not cancelled by the second pole piece.

It should be understood that the first direction of extension and the second direction of extension are opposite to each other only as an embodiment of the present invention, in other embodiments, the first extending direction may be the same as the second extending direction, for example, in the case that the first pole piece length is longer than the second pole piece length and the first extending direction is opposite to the winding direction of the first pole piece, the first extending direction is the same as the second extending direction, the length of the first connecting piece 21 is longer than that of the second connecting piece 22, so that the magnetic field generated by the current flowing through the first connection tab 21 is based on counteracting the magnetic field of the first pole piece that is not counteracted by the second pole piece, offset the magnetic field that second connection piece 22 produced simultaneously, the utility model discloses do not limit to first extending direction the same with second extending direction or on the contrary, as long as can cooperate through first connection piece 21 and second connection piece 22 jointly and offset the magnetic field that first pole piece was not offset by the second pole piece can.

In one embodiment, referring to fig. 1 to 10, the second connector 22 includes a connection part 221, one end of the connection part 221 is electrically connected to the second pole piece, and the other end of the connection part 221 is connected to the arc connection part 222.

Specifically, a connecting part 221 is provided on the second connecting part 22, so that on the one hand, the second connecting part 22 is electrically connected with the battery cell 1 through the connecting part 221; on the other hand, the second connecting piece 22 is convenient to be arranged on the battery cell 1, so that the connection strength between the second connecting piece 22 and the battery cell 1 is improved.

In one embodiment, the connecting member 2221 includes a first member and a second member perpendicularly connected to the first member, the second member being connected to the first end 2221 of the arc-shaped connecting portion 222; the first component is disposed on an end surface of the battery cell 1, and the arc-shaped connecting portion 222 is disposed on a peripheral side surface of the battery cell 1.

Specifically, the connection part 2221 includes a first part and a second part integrally formed with the first part. The first component is arranged on the end face of the battery cell 1 and electrically connected with the second pole piece of the battery cell 1. The second member extends to the circumferential side direction of the battery cell 1. One side of the second member is connected to the first end 2221 of the arc-shaped connecting portion 222. Such as the first member, the second member, and the arcuate connection portion 2221 are integrally formed.

In the embodiment, the second connecting piece 22 is electrically connected with the battery cell 1 through the connecting piece 221; on the other hand, the second connecting piece 22 is convenient to be arranged on the battery cell 1, so that the connection strength between the second connecting piece 22 and the battery cell 1 is improved.

In one embodiment, referring to fig. 2, 4, 6, 8 and 10, the arc-shaped connecting portion 222 is coaxially disposed with the battery cell 1.
