Description

Wireless earphone and electronic equipment

Technical Field

The invention relates to the technical field of earphones, in particular to a wireless earphone with a detachable earstem and electronic equipment using the wireless earphone.

Background

The Bluetooth headset is mainly divided into: mono bluetooth headset, stereo bluetooth headset and full wireless bluetooth headset.

The full wireless Bluetooth headset is the biggest difference with the traditional Bluetooth headset in that the wireless connection between the left ear and the right ear is realized by adopting the multi-point wireless interconnection technology. The earphone is electrically connected with the signal connection in a wireless mode. The left earplug and the right earplug of the full wireless earphone can work independently. When the two-channel stereo earphone is needed to be changed, the two earplugs are opened. The earphone is not stumbled by wires when sharing music, and is more convenient to use.

However, the full wireless bluetooth headset currently has the problems of short service time and frequent charging due to limited battery capacity. Especially when the user is required to interrupt music or put down his hand to charge. This brings trouble to the user and reduces the user experience.

It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.

According to one embodiment of the present invention, a wireless headset is provided. As shown in fig. 1-2, the wireless headset includes a earstem 11 and a headset housing 12. A power supply module is provided in the ear stem 11. The ear stem 11 has a connecting portion 13. The connection portion 13 is for connection with the earphone housing 12. A power management circuit is provided within the earphone housing 12. The connection portion 13 and the earphone housing 12 are detachably connected. The power module is electrically connected with the power management circuit. The power module is used for providing power. The power management circuit is used for transmitting power to each power utilization unit. For example, the power management circuit is a PCB16 (Printed Circuit Board, printed wiring board). Each power utilization unit is electrically connected with the PCB. The power module supplies power to each power utilization unit of the wireless earphone, such as a speaker unit 15, a main control chip and the like, through the PCB.

The wireless earphone adopts a modularized design. The ear stem 11 is detachably connected to the earphone housing 12. When the electric quantity in one ear 11 is insufficient or exhausted, the ear 11 with sufficient electric quantity can be directly detached and replaced.

In addition, the replacement of the power module is very convenient. The standby lug 11 is adopted to continuously supply power to the power utilization unit in the earphone shell 12, and long-time charging is carried out without stopping. The cruising ability of the wireless earphone is improved, and the user experience is improved.

In addition, the wireless earphone adopts a modularized design, so that the maintenance is convenient.

In the embodiment of the invention, the power supply module is in contact electrical connection or wireless electrical connection with the power supply management circuit. For example, contact electrical connection is made by contact of the contact 19 with the spring 17. The mode has good conduction performance and long service life.

In one example, as shown in fig. 2 and 3, the ear stem 11 is cylindrical. This configuration facilitates the placement of the power module and connection with the earphone housing 12. The connecting portion 13 is located at the side of the ear stem 11. A power supply module, for example, a lithium ion battery 14, a nickel cadmium battery, or a fuel cell, is provided in the ear stem 11. The battery has the characteristic of high capacity density.

For example, the power module has contacts 19 for electrical connection. The contact 19 is located at the connection portion 13. For example, the contact 19 of the lithium ion battery 14 protrudes from the connection portion 13. The power management circuit has a spring 17. The spring 17 is located on the earphone shell 12. When power is supplied, the contact 19 is in contact with the spring 17. The mode has simple structure, good conduction and convenient arrangement.

The wireless electrical connection uses, for example, a non-radiative wireless energy transfer means to transfer the power of the power module to the power management circuit. For example, a wireless power transmission module is provided in the ear stem 11, a wireless power reception module is provided in the earphone housing 12, and wireless power transmission is performed by both modules.

In the embodiment of the present invention, the connection portion 13 is in a snap connection and/or a magnetic connection with the earphone shell 12.

For example, as shown in fig. 1 and 3, a clip 18 is provided on the earphone housing 12, and a hook 20 is provided on the ear stem 11. The ear stem 11 is connected with the earphone shell 12 through the clamping connection of the clamping hook 20 and the clamping point 18.

For example, a first permanent magnet is provided on the earphone housing 12, a second permanent magnet is provided on the ear stem 11, and the ear stem 11 and the earphone housing 12 are connected together by the magnetic attraction of the first permanent magnet and the second permanent magnet. The mode has the characteristics of convenient connection and regular appearance.

Of course, a permanent magnet may be provided on either the earphone shell 12 or the ear stem 11, and an element made of iron, cobalt, or nickel, for example, a stainless steel sheet, may be provided on the other to realize magnetic attraction between the earphone shell 12 and the ear stem 11.

For example, both the clip 18 and the first permanent magnet are provided on the earphone housing 12, and both the clip 20 and the second permanent magnet are provided on the ear stem 11. The ear stem 11 is connected with the earphone shell 12 through the clamping connection of the clamping hook 20 and the clamping point 18 and the magnetic attraction of the two permanent magnets. In this way, the connection of the ear stem 11 and the earphone shell 12 can be made more secure.

In one example, the lugs 11 are plural. When the electric quantity of one ear 11 is insufficient or exhausted, the ear can be directly replaced. The number of lugs 11 can be set by a person skilled in the art according to the actual need.

In one example, the wireless headset further comprises charging means for charging said power supply module. For example, the charging device may employ contact charging or wireless charging.

In one example, as shown in fig. 4, the wireless headset further includes a bluetooth module 21. The bluetooth module 21 is arranged inside the earphone housing 12. The bluetooth module 21 is electrically connected to the power management circuit. For example, the bluetooth module 21 is integrated on the PCB16, and communication between two wireless headphones or communication between a wireless headphone and other electronic devices, such as a mobile phone, a tablet computer, is achieved through the bluetooth module 21.

According to another embodiment of the present invention, an electronic device is provided. For example, the electronic device is a cell phone, tablet computer, game console, intercom, wearable device, etc. The electronic equipment comprises the wireless earphone provided by the invention.
