For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In addition, in the present invention, the descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0041] Please refer to Figure 1 and Figure 2 The present invention proposes a device 100 combining a speaker and a Bluetooth headset, comprising a headset body 1 and a speaker body 2, wherein the speaker body 2 is provided with a receiving cavity 21 to receive the headset body 1 and charge the headset body 1. The headset body 1 and the speaker body 2 both include a shell and circuits and electronic components disposed in the shell.

[0042] Specifically, the earphone body 1 is provided with a Bluetooth chip 11, a switching unit 12 and an earphone battery 13 electrically connected to the Bluetooth chip 11, a first playback unit 14 electrically connected to the switching unit 12, and a first transmission connector 15 electrically connected to the earphone battery 13 and the switching unit 12. The Bluetooth chip 11 is used to wirelessly receive audio data sent by electronic devices such as smart phones via Bluetooth and perform codec analog-to-digital conversion of the data. The earphone battery 13 provides power for the Bluetooth chip 11, the switching unit 12, and the first playback unit 14.

[0043] The speaker body 2 is provided with a charging and voltage regulation management unit 22, a speaker battery 23 electrically connected to the charging and voltage regulation management unit 22, a charging interface 24 and a mode control button 25, a second playback unit 26, and a second transmission connector 27 electrically connected to the charging and voltage regulation management unit 22 and the second playback unit 26.

[0044] The first transmission connector 15 and the second transmission connector 27 are detachably connected for charging or audio data transmission.

[0045] The charging and voltage regulation management unit 22 charges the speaker battery 23 by connecting an external power source through the charging interface 24. The speaker battery 23 provides power for the second playback unit 26. At the same time, the earphone battery 13 is charged by connecting the first transmission connector 15 with the second transmission connector 27.

[0046] The mode control button 25 is used to control the output voltage of the charging and voltage regulation management unit 22, and the switching unit 12 is used to select whether to transmit the audio data received by the Bluetooth chip 11 to the first playback unit 14 or the second playback unit 26 or not to output the audio data and only charge according to the size of the output voltage. The charging and voltage regulation management unit 22 not only manages the charging of the speaker battery 23, but also adjusts the output voltage output by the speaker battery 23 to the second transmission connector 27, the first transmission connector 15, and the earphone battery 13. The adjustment of the output voltage is triggered by the mode control button 25. That is, after pressing the mode control button 25, the output voltage of the charging and voltage regulation management unit 22 will change.

[0047] The switching unit 12 detects the output voltage of the charging voltage regulation management unit 22 to select whether to output the audio data of the Bluetooth chip 11 to the first playback unit 14 of the earphone body 1 for playback or to output it to the second playback unit 26 of the speaker body 2 for playback, or to choose not to output the audio data and simply charge the earphone battery 13.

[0048] Since the first transmission connector 15 is detachably connected to the second transmission connector 27, as an implementation mode, the switching unit 12 can detect the input voltage of the first transmission connector 15 on the earphone body 1, that is, obtain the output voltage of the charging voltage regulation management unit 22.

[0049] If it is detected that the input voltage of the first transmission connector 15 is 0V, it indicates that the first transmission connector 15 is disconnected from the second transmission connector 27, and the earphone body 1 is taken out of the speaker body 2. At this time, the switching unit 12 sends the audio data of the Bluetooth chip 11 to the first playback unit 14 of the earphone body 1 for playback.

[0050] When it is detected that the input voltage of the first transmission connector 15 is in the range of 3.6V to 4.2V, it indicates that the first transmission connector 15 and the second transmission connector 27 are connected, the earphone body 1 is placed in the speaker body 2, and the voltage at this time is the normal working voltage of the Bluetooth chip 11. At this time, the switching unit 12 sends the audio data of the Bluetooth chip 11 to the second playback unit 26 of the speaker body 2 for playback.

[0051] When it is detected that the input voltage of the first transmission connector 15 is 5V, it indicates that the first transmission connector 15 and the second transmission connector 27 are connected at this time, the earphone body 1 is placed in the speaker body 2, and the voltage at this time is the charging voltage of the earphone battery 13. At this time, the switching unit 12 does not output the audio data of the Bluetooth chip 11, and only outputs the electric energy of the speaker battery 23 through the second transmission connector 27 and the first transmission connector 15 to the earphone battery 13 of the earphone body 1 for charging.

[0052] The device 100 of the present invention realizes the control of audio data playback and charging control through the Bluetooth chip 11 and the switching unit 12 on the earphone body 1, so the speaker body 2 no longer needs to be provided with a Bluetooth chip and a control chip. Compared with a separate Bluetooth earphone and a Bluetooth speaker, it saves circuit configuration and has a higher cost performance. At the same time, since the device 100 of the present invention is respectively provided with a first playback unit 14 and a second playback unit 26 on the earphone body 1 and the speaker body 2, the device has both the function of a Bluetooth earphone and the function of a Bluetooth speaker, which expands the function of the product and improves the application range of the product.

[0053] Specifically, Figure 3 As shown, the model of the Bluetooth chip 11 in the embodiment of the present invention is RDA5856E. The Bluetooth chip RDA5856E has 24 pins and is a high-performance, highly integrated multimedia Bluetooth chip that integrates baseband, Bluetooth transceiver, and power management into a system chip, which is professionally used in Bluetooth music and audio applications. It is suitable for Bluetooth speakers, Bluetooth music boxes, Bluetooth headphones, etc.

[0054] Preferably, if Figure 4 and Figure 5 As shown, the switching unit 12 of the embodiment of the present invention is provided with a switching MCU 121, and the switching MCU 121 model is WD2216-QFN20. That is, the switching unit 12 of the present embodiment is accurately controlled by a single chip microcomputer. The switching MCU 121 detects the voltage outputted to the first transmission connector 15 by the charging voltage regulation management unit 22 on the one hand, and selectively outputs the audio data sent by the Bluetooth chip 11 to the first playback unit 14 of the headset body 1 or the second playback unit 26 of the speaker body 2 through different output pins on the other hand. When charging the headset battery 13, the output pin of the switching MCU 121 does not output audio.

[0055] The WD2216-QFN20 chip and the RDA5856E chip are both powered by the earphone battery 13, and the power output end of the earphone battery 13 is connected to the VBAT pins of the WD2216-QFN20 chip and the RDA5856E chip.

[0056] Furthermore, if Figure 4 As shown, the first playback unit 14 includes a first power amplifier chip 141 electrically connected to the switching MCU 121 , and an earphone speaker 142 electrically connected to the first power amplifier chip 141 .

[0057] The second playback unit 26 includes a second power amplifier chip 261 electrically connected to the second transmission connector 27 , and a speaker 262 electrically connected to the second power amplifier chip 261 .

[0058] The first power amplifier chip 141 and the second power amplifier chip 261 respectively amplify the audio data sent by the Bluetooth chip 11 to the switching MCU 121 to drive the headphone speaker 142 and the speaker 262 for playback. The headphone body 1 and the speaker body 2 both use independent power amplifier chips so that the device 100 of the present invention can obtain good sound quality whether playing audio through the headphone speaker or the speaker speaker.

[0059] Preferably, the second power amplifier chip 261 of the embodiment of the present invention is CS4230E. Figure 6 The circuit of the second playback unit 26 of the embodiment of the present invention is shown, in which the INN (10) and INP (9) pins of the second power amplifier chip CS4230E are connected to the data transmission terminal of the second transmission connector 27 to receive the DAC_N and DAC_P differential audio signals output from the switching MCU. The OUTN (15) and OUTP (12) pins of the CS4230E are connected to the speaker 262.

[0060] Preferably, the earphone speaker 142 of the embodiment of the present invention is configured as a dynamic coil unit and / or a moving iron unit, so that the earphone body 1 can further provide high-quality sound quality.

[0061] like Figure 7 As shown, the first transmission connector 15 of the embodiment of the present invention includes a positive and negative power transmission terminal and a data transmission terminal. Correspondingly, the second transmission connector 27 includes a positive and negative power transmission terminal and a data transmission terminal, which are respectively used to electrically connect to the positive and negative power transmission terminal and the data transmission terminal of the first transmission connector 15. The positive and negative power transmission terminals are used to transmit electric energy for charging, while the data transmission terminals are used to transmit audio data. The first transmission connector 15 and the second transmission connector 27 can be in the form of plug connectors, interfaces, conductive pins, and other structural forms.

[0062] As an implementation method, combined with Figure 1 and Figure 7 The first transmission connector 15 of the embodiment of the present invention is a 4-pin female connector, and correspondingly, the second transmission connector 27 is a 4-pin male connector. When the earphone body 1 is placed in the accommodating cavity 21 of the speaker body 2, the 4-pin female connector of the earphone body 1 is in contact with the 4-pin male connector of the speaker body 2 for charging and data transmission.

[0063] like Figure 8 and Fig. 9As shown, the charging voltage regulation management unit 22 of the present invention includes a charging management chip 221 electrically connected to the speaker battery 23 and the charging interface 24, and a voltage regulation chip 222 electrically connected to the charging management chip 221, wherein the voltage regulation chip 222 is electrically connected to a mode control button 25 and a second transmission connector 27, and the mode control button 25 controls the output voltage of the voltage regulation chip 222; the model of the charging management chip 221 is ETA4054, and the model of the voltage regulation chip 222 is SGM6605.

[0064] The external power supply inputs power to the VCC pin of the charging management chip ETA4054 through the charging interface 24. The chip ETA4054 performs overload, short circuit and other charging protection on the input power, and outputs 3.6V~4.2V power to the BAT1+ terminal through the BAT pin. The BAT1+ terminal is connected to the speaker battery 23, and the BAT1+ terminal is connected to the VCC pin and SW pin of the voltage regulator chip SGM6605. The voltage regulator chip SGM6605 boosts the 3.6V~4.2V voltage input to the BAT1+ terminal to 5V and outputs it from the VOUT pin through the diode D4 to the OUT+ output terminal. The OUT+ output terminal is connected to the positive power transmission terminal of the second transmission connector 27, and the capacitors C10 and C22 play a filtering role. The VCC pin of the voltage regulator chip SGM6605 is connected to the BAT1+ terminal in parallel with the mode control button S5. S5 is connected in series with the resistor R26 and the diode D5 and then directly connected to the OUT+ output terminal. In this way, when the mode control button S5 is pressed to turn on, the 3.6V~4.2V electric energy of the speaker battery 23 is directly output to the second transmission connector 27 through BAT1+, S5, R26, D5, and OUT+, without the boost processing of the voltage regulator chip SGM6605. At this time, if the first transmission connector 15 is connected to the second transmission connector 27, the input voltage detected by the switching MCU121 at the first transmission connector 15 is 3.6V~4.2V, and the switching MCU121 transmits the audio of the Bluetooth chip 11 to the speaker body 2 for playback.

[0065] When the mode control button S5 is lifted, that is, S5 is not conducting, the 3.6V~4.2V electric energy of the speaker battery 23 passes through BAT1+ and enters the VCC pin of the voltage regulator chip SGM6605S5, and is boosted to 5V by the voltage regulator chip SGM6605S5, and then output to the second transmission connector 27 through D4, OUT+. At this time, if the first transmission connector 15 is connected to the second transmission connector 27, the input voltage detected by the switching MCU121 on the first transmission connector 15 is 5V, and the switching MCU121 does not output the audio of the Bluetooth chip 11, and directly charges the earphone battery 13.

[0066] Preferably, the speaker body 2 of the embodiment of the present invention has two accommodating cavities 21 for accommodating two earphone bodies 1, and a second transmission connector 27 is provided at the bottom of each of the accommodating cavities 21, which can be connected to a first transmission connector 15 at the bottom of an earphone body 1. In this way, the earphone body 1 of this embodiment can be set as a TWS earphone, further improving the sound quality played by the earphone body 1.

[0067] The headset body 1 of the embodiment of the present invention is also provided with an LED light 16 and a function button 17 electrically connected to the Bluetooth chip 11. The LED light 16 sends a prompt signal, and the function button 17 is used to control the headset body 1, such as turning the headset body on and off, adjusting the volume, etc.

[0068] The device 100 of the present invention is divided into three modes:

[0069] 1. Headphone mode:

[0070] At this time, the earphone body is taken out from the speaker body, the first transmission connector is disconnected from the second transmission connector, and the input voltage obtained by the first transmission connector from the second transmission connector is zero, that is, the voltage output by the charging voltage regulation management unit to the first transmission connector is zero. At this time, it is the earphone mode, and the audio is transmitted to the earphone speaker for playback.

[0071] The headphone mode has the same functions as ordinary Bluetooth headphones, and can be used for normal operations such as listening to music and making calls.

[0072] 2. Speaker mode:

[0073] The earphone body is placed in the speaker body, the first transmission connector is connected to the second transmission connector, and the mode control button on the speaker body is pressed. The output of the second transmission connector to the first transmission connector is 3.6-4.2V. At this time, it is the speaker mode, and the audio is transmitted to the speaker for playback. In this mode, the Bluetooth chip calls the battery in the speaker body to ensure sufficient power, and calls the high-quality speaker in the speaker body to ensure the sound quality when the speaker body is playing.

[0074] 3. Charging mode:

[0075] The earphone body is placed in the speaker body, the first transmission connector is connected to the second transmission connector, and the mode control button on the speaker body is lifted. The output of the second transmission connector to the first transmission connector is 5V. At this time, it is in charging mode, and the Bluetooth chip does not output audio. In this mode, the earphone battery of the earphone body enters the charging mode, so that the speaker battery of the speaker body charges the earphone battery of the earphone body, thereby increasing the battery life of the earphone battery.

[0076] The device 100 of the present invention combines a Bluetooth headset and a Bluetooth speaker, so that the device 100 has the functions of a Bluetooth headset and a Bluetooth speaker at the same time, and has the portability and privacy of a Bluetooth headset, as well as the playability, sharing and high sound quality of a Bluetooth speaker.

[0077] The device 100 combining a speaker and a Bluetooth headset proposed in an embodiment of the present invention comprises a headset body 1 and a speaker body 2 for accommodating the headset body 1. The headset body 1 is provided with a Bluetooth chip 11, a switching unit 12, a first playback unit 14 and a first transmission connector 15. The speaker body 2 is provided with a charging and voltage regulation management unit 22, a mode control button 25, a second playback unit 26 and a second transmission connector 27. The first transmission connector 15 and the second transmission connector 27 are detachably connected for charging or audio data transmission between the headset body 1 and the speaker body 2. The mode control button 25 is used to adjust the charging voltage regulation management unit 22, the mode control button 25, the second playback unit 26 and the second transmission connector 27. The output voltage of the charging and voltage regulation management unit 22 is adjusted, and the switching unit 12 selects to transmit the audio data received by the Bluetooth chip 11 to the first playback unit 14 or the second playback unit 26 according to the size of the output voltage, or not to output the audio data and only charge. In this way, the device 100 of the present invention provides audio data to the earphone body 1 or the speaker body 2 through the same Bluetooth chip 11, and selects to use the earphone body 1 to play audio or the speaker body 2 to play speakers or only charge the earphone body through the switching unit 12, so that the device 100 has the functions of Bluetooth earphones and Bluetooth speakers at the same time, with a simple structure and high cost performance.

[0078] The above description is only an example to clearly illustrate the present invention, and does not limit the patent scope of the present invention. It is impossible to list all the implementation methods here. All equivalent structural changes made by using the contents of the technical solution of the present invention under the concept of the present invention, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
