A microphone hole (not shown) is provided at one end (i.e., the bottom) of the first connection portion 114, and a waterproof membrane is provided at the microphone hole. Thus, by providing the waterproof membrane, the waterproof performance can be effectively improved to prevent water from directly entering the second receiving groove 124 from the microphone hole.

[0109] In one possible implementation, see Figure 2 A touch area 125 is provided on the outer wall of the second shell portion 121 . The touch area 125 is electrically connected to the earphone body 20 . The user controls the earphone by manipulating the touch area 125 .

[0110] See also Figure 3 The first shell 110 and the second shell 120 are buckled together to form a general connection part 140 and a general shell part 150. The general shell part 150 is arranged in the middle of one side of the general connection part 140 and is substantially perpendicular to the general connection part 140. The microphone hole is opened at one end (i.e., the bottom) of the general connection part 140.

[0111] Specifically, Figure 1 As shown, the first connection part 114 and the second connection part 123 are mutually buckled to form the general connection part 140, and the general connection part 140 is cylindrical. When the first connection part 114 is buckled to the second connection part 123, the first receiving groove 115 and the second receiving groove 124 together form the first receiving cavity. The first housing part 111 and the second housing part 121 are mutually buckled to form the general housing part 150, and the general housing part 150 is round. When the first housing part 111 is buckled to the second housing part 121, the second receiving groove 113 and the third receiving groove 122 are connected to each other. The second receiving groove 113 is arranged between the first receiving groove 112 and the third receiving groove 122. The first receiving groove 112, the second receiving groove 113 and the third receiving groove 122 are connected to each other to form the second receiving cavity. The first receiving cavity and the second receiving cavity are connected to each other to form the general cavity.

[0112] In the embodiment of the present application, the first housing portion 111 is detachably connected to the second housing portion 121. The first connecting portion 114 is detachably connected to the second connecting portion 123.

[0113] In one possible implementation, a glue layer is provided at the connection between the first housing portion 111 and the second housing portion 121 to fix the connection between the first housing portion 111 and the second housing portion 121. In addition, in other embodiments, a waterproof rubber pad may be provided at the connection between the first housing portion 111 and the second housing portion 121, wherein the waterproof rubber pad is firstly provided between the first housing portion 111 and the second housing portion 121 to connect each other, and then the two are fixed by glue to achieve both fixing and waterproofing effects.

[0114] Similarly, a glue layer is provided at the connection between the first connection part 114 and the second connection part 123 to fix the connection between the first connection part 114 and the second connection part 123. In addition, in other embodiments, a waterproof rubber pad may be provided at the connection between the first connection part 114 and the second connection part 123, wherein the waterproof rubber pad is firstly provided between the first connection part 114 and the second connection part 123 to connect each other, and then the two are fixed by glue to achieve both fixing and waterproofing effects.

[0115] In the embodiments of the present application, Figure 1 As shown, the ear hook 130 is connected to the main connecting part 140 .

[0116] In the embodiment of the present application, the ear hook 130 is bent as a whole into a shape that can be hung at the root of the auricle. The ear hook 130 includes a first connection end 131 and a free end 132. The first connection end 131 is connected to the second connection portion 123 of the earphone housing 10, and the free end 132 is an end of the ear hook 130 that is away from the first connection end 131, and the free end 132 is arc-shaped. When the user uses the ear hook 130, the ear hook 130 is hooked on the ear, the ear hook 130 contacts the ear, the free end 132 is suspended, the free end 132 is close to the auricle area of ​​the ear, and is located above the back side of the ear, such as the free end 132 is located above the tragus.

[0117] Specifically, the ear hook 130 includes a main body 133 and an extension 134. One end of the main body 133 is connected to the first connection end 131 so as to be connected to the earphone housing 10 through the first connection end 131, and the other end of the main body 133 is connected to the extension 134. The main body 133 extends in a vertical direction, that is, when the main body 133 extends in a vertical direction, it gradually extends obliquely to one side, so that the other end of the main body 133 gradually extends obliquely upward to the root of the auricle. The extension 134 extends obliquely downward along the outer surface of the main body 133, that is, when the extension 134 extends in the extension direction of the main body 133, it extends downward close to the ear, so that after the other end of the main body 133 extends to the root of the auricle, the extension 134 extends downward from the other end of the main body 133, so that the ear hook 130 can be hooked on the ear. When the ear hook structure 100 is worn, based on the shapes of the main body 133 and the extension portion 134 , the ear hook structure 100 can be hung on the ear, and the free end 132 is located above the first connection end 131 , that is, the extension arc of the ear hook 130 is shorter.

[0118] In the embodiment of the present application, the width of the ear hook 130 gradually decreases from the main body 133 to the extension portion 134. In one possible implementation, the ear hook 130 is cylindrical as a whole, and its radius gradually decreases from the first connection end 131, the main body 133, the extension portion 134 to the free end 132.

[0119] It should be noted that the ear hook 130 can be made of a silicone material. Of course, in other embodiments, a titanium steel wire can also be arranged in the ear hook 130 to be bent into a fixed shape by the titanium steel wire.

[0120] In one possible implementation, see Figure 4 and Figure 5 , the second connection part 123 is provided with a receiving hole 126 and a clamping part 127, and the first connection end 131 is provided with an inserting cavity 135 corresponding to and cooperating with the clamping part 127. The inserting cavity 135 is detachably connected to the clamping part 127. Specifically, the receiving hole 126 is provided on the top of the second connection part 123, and one end of the clamping part 127 is used to be inserted into the receiving hole 126. When one end of the clamping part 127 is inserted into the receiving hole 126, a part of the clamping part 127 protrudes from the horizontal plane of the receiving hole 126, and the protruding part of the clamping part 127 is inserted into the inserting cavity 135.

[0121] It should be noted that the detachable connection method between the ear hook 130 and the earphone housing 10 includes, but is not limited to: plug connection, threaded connection, snap connection, contact connection, etc. It only needs to satisfy the requirement that the ear hook 130 and the main connection part 140 are detachably connected, and this application does not make any specific limitations on this.

[0122] In one possible implementation manner, the ear hook 130 is fixedly connected to the main connecting portion 140 , and the ear hook 130 and the main connecting portion 140 are integrally formed.

[0123] In the embodiment of the present application, the specific structure and type of the ear hook 130 are not limited. For example, the ear hook 130 can be an ear hook structure, a neck hook structure, or a head-mounted bone conduction headset.

[0124] For example, see Figure 6 The ear hook 130 can be implemented as a head-mounted ear hook. Figure 1 The difference of the hook-type ear hook shown is that the extension arc of the head-mounted ear hook is longer than the extension length of the hook-type ear hook, and the ear hooks of the two earphones are connected together. By setting the head-mounted ear hook, it is possible to reduce the burden of weight on the ear to provide comfort when worn.

[0125] It should be noted that when the ear hook 130 is a head-mounted ear hook type, the TWS bone conduction headset 1 may not include an earplug 30, and the bone conduction vibrator 202 is directly placed close to the ear bone for vibration and sound transmission. Alternatively, the TWS bone conduction headset 1 may also include a protective cover (not shown), which is sleeved on the bone conduction vibrator 202 to protect the bone conduction vibrator 202, and the bone conduction vibrator 202 and the protective cover are placed in the ear bone area, and the vibration of the bone conduction vibrator 202 is transmitted through the protective cover to transmit sound. Alternatively, the TWS bone conduction headset 1 also includes an earplug 30, which is sleeved on the bone conduction vibrator 202. When the head-mounted ear hook is worn, the bone conduction vibrator 202 and the earplug 30 are inserted into the ear together.

[0126] In one possible implementation, when the ear hook 130 is not in use, a cap (not shown) is provided on the receiving hole 126 on the second connecting portion 123 to cover the receiving hole 126 for waterproofing and dustproofing.

[0129] In the embodiment of the present application, if there is sufficient space between the first housing portion 111 and the second housing portion 121, the TWS bone conduction headset 1 can be provided with only one PCB board, and all the circuit parts are concentrated on one PCB board. Alternatively, the first PCB board 211 is not necessarily provided in the first receiving cavity, but can also be directly provided in the second receiving cavity, depending on the actual production requirements, and the present application does not make any specific limitation on this.

[0130] In an embodiment of the present application, the storage module 208 is arranged on the second PCB board 212, and the storage module 208 may include a high-speed random access memory, and may also include a non-volatile memory, such as a hard disk, a memory, a plug-in hard disk, a smart memory card (Smart Media Card, SMC), a secure digital (Secure Digital, SD) card, a flash card (Flash Card), at least one disk storage device, a flash memory device, or other volatile solid-state storage devices.

[0131] In an embodiment of the present application, the storage module 208 stores a Bluetooth address code, which is a Bluetooth address code corresponding to a Bluetooth device to be paired and connected, and the Bluetooth address code may include multiple Bluetooth address codes. The Bluetooth address code may be a Bluetooth address code corresponding to a Bluetooth device to be paired and pre-stored by a user, or the Bluetooth address code may be a Bluetooth address code saved after obtaining the address code of the Bluetooth device by searching for nearby Bluetooth devices during use. The TWS bone conduction headset 1 can be connected to different Bluetooth devices by Bluetooth according to the multiple Bluetooth address codes pre-stored in the storage module 208. The Bluetooth device may be an electronic device with Bluetooth function, such as a mobile phone, a headset, a computer or a tablet. Exemplarily, the Bluetooth address code includes a first Bluetooth address code and a second Bluetooth address code, the first Bluetooth address code is used to connect to the first Bluetooth device by Bluetooth, and the second Bluetooth address code is used to connect to the second Bluetooth device by Bluetooth. In this embodiment, the type of Bluetooth device is not limited. For example, the first Bluetooth device and the second Bluetooth device may be different products or products of the same type, such as the first Bluetooth device is a mobile phone and the second Bluetooth device is a headset.

[0132] In the embodiment of the present application, the Bluetooth module 209 is disposed on the second PCB board 212 . The Bluetooth module 209 includes a Bluetooth chip and may also include a unit or device having a Bluetooth function and a control function.

[0135] In one possible implementation, the power amplifier is used to amplify the signal output by the Bluetooth module 209, and output the amplified signal to the bone conduction vibrator 202. By setting the power amplifier, the output power is increased, the sound signal is amplified, and the listening effect is improved.

[0136] It should be noted that the power amplifier may be an independent circuit or chip, or the power amplifier may be integrated with a processor, that is, the corresponding power amplification function is realized by setting a corresponding processor, and this application does not make any specific limitation on this.

The microphone 205 is electrically connected to the circuit board 201 and is used to convert the audio signal into an electrical signal. When the TWS bone conduction headset 1 is hung on the ear through the ear hook 130, the microphone hole is located below the headset, close to the mouth, and the microphone 205 collects the sound of the user's speech and converts it into an electrical signal. The microphone 205 can be a dynamic, condenser, electret and silicon micro-microphone, which is not specifically limited in this application.

Exemplarily, the user touches the touch area 125 to control the headset body 20 of the TWS bone conduction headset 1, such as activating the Bluetooth module 209 of the headset body 20.

[0147] Please also read Figures 7 to 9 The earplug 30 is disposed on one side of the second housing portion 121, and one side of the earplug 30 is recessed to form a groove 31 (see Fig. 9 The groove 31 is covered on the bone conduction vibrator 202 exposed from the third accommodating groove 122, and the groove 31 includes an ear-entry side 32 facing the ear and a connection side 33 facing the bone conduction vibrator 202. The ear-entry side 32 contacts the ear, and the connection side 33 contacts the bone conduction vibrator 202 and the second housing portion 121.

[0148] In one possible implementation, a glue layer is provided at the connection between the connection side 33 and the second housing portion 121 to fix the connection between the connection side 33 and the second housing portion 121. In addition, in other embodiments, a waterproof rubber pad may be provided at the connection between the connection side 33 and the second housing portion 121 to fix the connection between the connection side 33 and the second housing portion 121 and to provide a waterproof effect. Of course, in other embodiments, a glue layer and a waterproof rubber pad may also be provided at the same time. Among them, the waterproof rubber pad is first provided between the connection side 33 and the second housing portion 121 to connect each other, and then the two are fixed by glue to provide a fixing and waterproof effect at the same time.

[0149] In the embodiment of the present application, a positioning protrusion 34 is provided on the side of the earplug 30 facing the ear, and the positioning protrusion 34 is obliquely protruded outward from the outer peripheral side of the earplug 30 .

[0150] Specifically, the positioning protrusion 34 includes a first protrusion 341 connected to the earplug 30 and a second protrusion 342 integrally connected to the first protrusion 341. The second protrusion 342 extends from the outer peripheral side of the first protrusion 341 along the extension direction of the first protrusion 341. The upper and lower ends of the first protrusion 341 are both arc-shaped structures, and the second protrusion 342 is an arc-shaped structure as a whole. One end of the first protrusion 341 extends integrally to the outer peripheral side of the earplug 30 and the peripheral area of ​​the side of the earplug 30 facing the ear. A concave arc section (not shown) is provided on the side of the first protrusion 341 facing the ear; one end of the concave arc section extends to the inside of the side of the earplug 30 facing the ear, and the other end extends to the inside of the side of the second protrusion 342 facing the ear. When the ear hook structure 100 is worn, the first protrusion 341 and the second protrusion 342 extend toward the ear, and the width of the positioning protrusion 34 gradually decreases from the first protrusion 341 to the second protrusion 342 .

[0151] In the embodiment of the present application, the bone conduction vibrator 202 is extended into the ear along with the earplug 30, and the earplug 30 is covered on the other part of the bone conduction vibrator 202 exposed from the side of the second shell portion 121. The earplug 30 is in contact with the bone conduction vibrator 202, and the ear-entry side 32 of the earplug 30 is in contact with the bone of the ear, thereby conducting the vibration of the bone conduction vibrator 202 through the earplug 30 to achieve bone conduction sound. At this time, the positioning protrusion 34 enters the ear along with the earplug 30, and the first protrusion 341 and the second protrusion 342 extend outward. When inserted into the ear, the first protrusion 341 and the second protrusion 342 are clamped in the ear, and the first protrusion 341 and the second protrusion 342 generate a force on the ear area they contact. Under the force, the first protrusion 341 and the second protrusion 342 play a role of positioning and fixing in the ear. At the same time, the first protrusion 341 and the second protrusion 342 of the positioning protrusion 34 can also play a role of transmitting vibration when contacting the ear.

[0152] In one possible implementation, the positioning protrusion 34 is preferably a silicone protrusion made of silicone material. The silicone protrusion is a soft material, which makes it more comfortable to wear and avoids the positioning protrusion causing discomfort to the wearer.

[0153] See also Fig.10 , Fig.10It is a schematic diagram of the communication connection between the TWS bone conduction headset 1 and the first electronic device 2 and the second electronic device 3 according to a preferred embodiment of the present application. The first electronic device 2 and the second electronic device 3 are electronic devices with Bluetooth function. In other embodiments, the first electronic device 2 and the second electronic device 3 can be a mobile phone, headset, personal computer, tablet computer, personal digital assistant (Personal Digital Assistant, PDA), game console, interactive network television (Internet Protocol Television, IPTV), smart wearable device, navigation device and other mobile devices, or desktop computers, digital TV and other electronic devices.

[0154] The TWS bone conduction earphone 1 can be the master earphone and / or slave earphone in a pair of TWS earphones. The structure and function of the master earphone and the slave earphone are consistent. For example, the master earphone and the slave earphone both include an earphone housing 10, an earphone body 20 and an earplug 30, which are not described here. The master earphone and the slave earphone are connected by Bluetooth. The master earphone and the slave earphone are used to convert the sound signal received through the Bluetooth connection into mechanical vibrations of different frequencies.

[0155] In this embodiment, the application scenario is described by taking the TWS bone conduction headset 1 as the master headset in a pair of headsets, the first electronic device 2 as a mobile phone, and the second electronic device 3 as the slave headset paired with the master headset as an example.

[0156] After the user gets the master earphone, he touches the touch area 125 to wake up the master earphone. The master earphone is turned on. The user touches the touch area 125 again, and the master earphone turns on the Bluetooth module 209. The master earphone searches for nearby Bluetooth devices. The user turns on the Bluetooth of the mobile phone, and the master earphone is paired with the mobile phone through the pre-stored Bluetooth address code. Correspondingly, the user can also turn on the slave earphone by touching the touch area 125 on the slave earphone. When the user touches the touch area 125 on the slave earphone again, the slave earphone searches for the Bluetooth signal of the master earphone and then connects to the master earphone through Bluetooth. In one possible implementation, the Bluetooth module of the slave earphone is in an on state for a long time. When the user touches the touch area 125 of the master earphone, the master earphone turns on and turns on the Bluetooth module 209 of the master earphone, and then the master earphone is paired with the slave earphone through Bluetooth, so that the Bluetooth connection of the slave earphone is controlled by the master earphone.

[0157] The master earphone is paired with the slave earphone and the mobile phone, and can perform Bluetooth communication. The Bluetooth module 209 of the master earphone receives the audio signal transmitted by the mobile phone, and processes the received audio signal through the module on the circuit board 201 of the master earphone to obtain the corresponding audio signal. The power amplifier 213 amplifies the output audio signal, and outputs the amplified signal to the bone conduction vibrator 202. The output audio signal is processed by the power amplifier 213, the output power is increased, the sound signal is amplified, and the listening effect is improved. The bone conduction vibrator 202 of the master earphone converts the audio signal into mechanical vibrations of different frequencies, and then transmits it through the following conduction pathways: skull-bone labyrinth-inner ear lymph fluid-spiral device-auditory nerve-cerebral cortex auditory center. Specifically, the mechanical vibration is transmitted to the bone labyrinth through the user's skull, and then the inner ear lymph fluid vibrates, the spiral device completes the sound perception process, and then the auditory nerve generates nerve impulses and presents them to the auditory center. After comprehensive analysis by the cerebral cortex, the user finally "hears" the sound. Correspondingly, the Bluetooth module 209 of the slave earphone receives the audio signal transmitted from the mobile phone to the master earphone from the Bluetooth module 209 of the master earphone, and the Bluetooth module 209 of the slave earphone transmits the received audio signal to the circuit board 201 of the slave earphone, so as to be processed by the module of the circuit board 201 of the slave earphone to obtain the corresponding audio signal, and the bone conduction vibrator 202 of the master earphone vibrates and transmits sound according to the audio signal. Its working principle is similar to that of the master earphone, and will not be repeated here.

[0158] In the embodiment of the present application, the overall waterproof performance of the earphone is improved through the combined design of the glue layer and the waterproof rubber pad, ensuring its normal use during sports such as running and swimming, thereby improving environmental applicability.

[0159] In summary, through the combination of TWS technology and bone conduction technology, the TWS bone conduction earphones of the present application are free from the constraints of data cables and are more convenient to use. Moreover, the bone conduction vibrator 202 vibrates the bones to transmit the sound to the brain, avoiding the damage to hearing caused by air conduction, achieving the freedom of wearing without being bound by data cables, and protecting the eardrum, which can provide a more perfect user experience for the users of the TWS bone conduction earphones 1 and allow them to enjoy wonderful music at any time.

[0160] Furthermore, by reasonably setting the gap size between the bone conduction vibrator 202 and the battery 203, it can be ensured that the bone conduction vibrator 202 has enough space, so that the swing amplitude of the bone conduction vibrator 202 is large, and the overall space of the TWS bone conduction headset 1 is small.

[0161] Furthermore, the ear hook 130 of the TWS bone conduction earphone of the present application cooperates with the positioning protrusion 34 to achieve a stable wearing effect. The ear hook 130 is exquisitely designed to make the earphone more beautiful, thereby improving the user experience. The earplug 30 is provided to cooperate with the ear hook to further improve the wearing stability.

[0162] Furthermore, the first protrusion 341 and the second protrusion 342 of the positioning protrusion 34 on the earplug 30 strengthen the positioning and fixation of the earphone, solve the problem of low sound and unclear hearing caused by loose in-ear wearing, avoid the earphone from falling off, improve the user experience, and can play a role in transmitting vibration, so that when it is applied to TWS bone conduction earphone 1, it can cooperate with the bone conduction vibrator 202 in the earphone to achieve a better effect of transmitting vibration.

[0163] Secondly, the ear hook is detachably connected to the earphone, so that the ear hook can be detachably and replaceably set, so that different ear hooks can be replaced for different users. Those skilled in the art should realize that the above implementation is only used to illustrate the present application, and is not used as a limitation of the present application. As long as it is within the spirit of the present application, appropriate changes and modifications made to the above embodiments should fall within the scope of protection claimed by the present application.
