All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The intercom device plays a very important role in trunking communication, is used for the contact among group members, and is widely applied to civil, industrial, police and other fields, but the confidentiality of voice communication of the intercom device is not strong, and when the external environment is noisy, the voice communication of the intercom device is greatly interfered, a user is difficult to clearly listen to conversation contents, the use quality of the intercom device is influenced, and the use scene of the intercom device is limited. In addition, the service environment of the intercom device is often more complicated, and the user can expect to keep better perception to the external environment while carrying out the intercom communication, thereby ensuring that the user is safer. In order to improve the above technical problem, the present application proposes an embodiment of a headset communication system, which is described in detail below.
As shown in fig. 1 and 2, the embodiment of the headset communication system of the present application includes a bone conduction headset 1, an intercom device 2, and an external communication module 3.
The bone conduction headset 1 converts audio frequency into mechanical vibration of different frequencies, uses human bones as a medium for transmitting the mechanical vibration, and then transmits sound waves to auditory nerves, so that a user can receive sound without passing through the external auditory canal and the eardrum of the ear. In this embodiment, the bone conduction headset 1 may have a bluetooth function. As shown in fig. 2, the bone conduction headset 1 may include a first bluetooth module 101. The first bluetooth module 101 may be used to implement a bluetooth communication function.
The intercom device 2, i.e. an intercom, is a terminal device of trunking communication, and may also be used as a wireless communication device in mobile communication. Generally speaking, an intercom converts an electrical signal of audio frequency into a radio frequency carrier signal through a transmitting component thereof, and then transmits the radio frequency carrier signal through an antenna in modes of amplification, filtering and the like, so that the sound of a user can be transmitted. The antenna can receive input signals, and audio signals are formed through corresponding conversion, filtering, amplification, mixing and other processing and are played through the loudspeaker, so that a user can hear audio sent by other talkback equipment. The intercom device 2 in the present embodiment may be an existing intercom device, and the components and structure thereof will not be described in detail here.
The existing intercom device does not basically support the bluetooth function, and in order to enable the bone conduction headset 1 to be connected with the intercom device 2 in an effective bluetooth manner, the external communication module 3 is used as a medium for performing bluetooth communication between the bone conduction headset 1 and the intercom device 2 in the embodiment.
Specifically, the intercom device 2 may include the first external interface 201. That is, the intercom device 2 may be provided with the first external interface 201 for extending the functions of the intercom device 2, and different functions may be realized by connecting different external modules. The first external interface 201 may also be used for an external terminal to program the intercom device 2. The first external interface 201 may include a plurality of contacts (shown in fig. 1 but not labeled) arranged at intervals, for example, 7 contacts.
The external communication module 3 may include a second external interface 301 and a second bluetooth module 302. The external communication module 3 is detachably disposed on the intercom device 2, for example, the external communication module 3 is fixed to the intercom device 2 in a clamping manner. The second external interface 301 may have as many contacts as the first external interface 201. When the external communication module 3 is installed in the intercom device 2, the first external interface 201 is connected with the second external interface 301. The external communication module 3 is coupled to the intercom device 2 through the first external interface 201 and the second external interface 301. The intercom device 2 can realize the Bluetooth function through the external communication module 3.
As shown in fig. 2, the intercom device 2 may establish a bluetooth connection with the bone conduction headset 1 through the external communication module 3. After talkbacking equipment 2 and bone conduction headset 1 have established bluetooth and have connected through external communication module 3, can use bone conduction headset 1 to control talkbacking equipment 2, for example can use bone conduction headset 1 to answer the audio frequency that talkbacking equipment 2 received, also can use bone conduction headset 1's microphone to send corresponding pronunciation, can also control other functions of talkbacking equipment 2. Of course, the intercom device 2 may also control the bone conduction headset 1.
In some embodiments, in order to facilitate a fast bluetooth connection between the bone conduction headset 1 and the intercom device 2, bluetooth addresses may be exchanged between the bone conduction headset 1 and the intercom device 2 quickly to facilitate a fast pairing. As shown in fig. 2, the bone conduction headset 1 may further have an NFC near field communication function, and may specifically include a first NFC module 102, which may be used to implement the near field communication function. The external communication module 3 may further include a second NFC module 303, so that the intercom device 2 without the NFC near-field communication function may implement near-field communication.
Specifically, the bone conduction headset 1 and the intercom device 2 may exchange bluetooth addresses through near field communication of the first NFC module 102 and the second NFC module 303, so that the first bluetooth module 101 and the second bluetooth module 302 perform bluetooth pairing to establish a bluetooth connection. For the above exchange of bluetooth addresses, there may be the following:
the first mode is as follows: the bone conduction headset 1 sends the Bluetooth address to the intercom device 2, so that the time for the intercom device 2 to search and select the bone conduction headset 1 can be saved. That is, the first NFC module 102 may store or acquire the bluetooth address of the first bluetooth module 101. When the first NFC module 102 and the second NFC module 303 perform near field communication, the first NFC module 102 may send the bluetooth address to the second NFC module 303, so that the external communication module 3 may acquire the bluetooth address of the first bluetooth module 101, thereby implementing bluetooth address exchange, and further performing rapid pairing and connection.
The second mode is as follows: the intercom 2 sends the bluetooth address to the bone conduction headset 1, so that the time for the bone conduction headset 1 to search and select the intercom 2 can be saved. That is, the second NFC module 303 may store or acquire the bluetooth address of the second bluetooth module 302. When the first NFC module 102 and the second NFC module 303 perform near field communication, the second NFC module 303 may send the bluetooth address of the second bluetooth module 302 to the first NFC module 102, so that the bone conduction headset 1 may acquire the bluetooth address of the second bluetooth module 302, thereby implementing bluetooth address exchange, and further performing fast pairing and connection.
The third mode is as follows: the intercom device 2 and the bone conduction headset 1 both actively send respective bluetooth addresses, so that the time for searching and selecting between the two devices is saved, and rapid pairing and connection are realized. That is, the first NFC module 102 may store or acquire the bluetooth address of the first bluetooth module 101, and the second NFC module 303 may store or acquire the bluetooth address of the second bluetooth module 302. When the first NFC module 102 and the second NFC module 303 perform near field communication, the first NFC module 102 and the second NFC module 303 exchange bluetooth addresses with each other, so as to implement exchange of the bluetooth addresses.
The intercom device 2 realizes a fast bluetooth connection through the second NFC module 303 of the external communication module 3 and the first NFC module 102 of the bone conduction headset 1, so that the intercom device 2 can be fast matched with different bone conduction headsets 1. Taking industrial field work as an example, different staff configure different bone conduction earphones 1, for example two staff can share one intercom 2, and these two staff can alternate use shared intercom 2 when the shift, can connect intercom 2 fast through bone conduction earphones 1. When a worker is on duty, the bone conduction headset 1 and the talkback device 2 of the worker are used to realize 'connection by collision', and then the talkback device 2 and the bone conduction headset 1 can be used to form a communication system. When the staff goes off duty and another staff starts to watch duty, the other staff can also connect the bone conduction earphone 1 and the intercom device 2 in a collision manner, and then use the communication system formed by the intercom device 2 and the bone conduction earphone 1 to form an operation logic with coexistence of 'independence' and 'sharing', wherein each person can use the bone conduction earphone 1 independently and the intercom device 2 is shared. The communication system of this embodiment can also be individual with 1 sign of bone conduction earphone, and then can many people use same platform equipment of talkbacking 2, can realize fast switch over, can also realize functions such as attendance punch card, discernment individual identity.
Intercom 2 and bone conduction headset 1 carry out the bluetooth fast through NFC near field communication's mode and pair and then establish the bluetooth and connect, bone conduction headset 1 can release user's ears when being worn, mode transmission sound through bone conduction, can reduce the influence of ambient environment's noise to sound transmission, promote speech communication's quality, and play audio signal that intercom 2 received through bone conduction headset 1 or pick up sound through bone conduction headset 1 and transmit to other intercom 2 through intercom 2, can avoid the mode that traditional talkback was put outward, can protect the privacy more, in addition to application scenes such as factory workshop, the user also can notice ambient environment's change when using bone conduction headset 1 to carry out the intercommunication, can guarantee user's safety.
For the bone conduction headset 1, the first NFC module 102 may be a passive type NFC module. The first NFC module 102 may store the bluetooth address of the first bluetooth module 101, and may send the bluetooth address of the first bluetooth module 101 to the second NFC module 303. Of course, the first NFC module 102 may also be an active NFC module, and may send the bluetooth address of the first bluetooth module 101, or receive the bluetooth address of the second bluetooth module 302 sent by the second NFC module 303. Similarly, the second NFC module 303 may also be a passive NFC module or an active NFC module.
The first NFC module 102 may be attached to a battery assembly of the bone conduction headset 1, so that the mounting is convenient, the structure is simple, and the space can be saved. When needs and intercom 2 carry out the bluetooth and connect, be close to external communication module 3 on the intercom 2 with the position that the battery pack of bone conduction earphone 1 corresponds, can carry out the bluetooth fast and pair.
In some embodiments, to facilitate the control between the intercom device 2 and the bone conduction headset 1, the switching of the related functions between the intercom device 2 and the bone conduction headset 1 is automatically achieved, which can be sensed and controlled by corresponding sensors, as an example:
as shown in fig. 2, the bone conduction headset 1 may comprise a sensor assembly 17 for detecting whether the bone conduction headset 1 is worn. In particular, the sensor assembly 17 comprises, for example, an optical sensor, detecting whether it is worn or not by emitting and/or receiving a corresponding light signal. The optical sensor is, for example, a low-beam sensor, which can emit a corresponding light signal, reflect the light signal to generate an emitting light when the bone conduction headset 1 is worn, and does not generate a reflecting light when the bone conduction headset 1 is not worn, and the low-beam sensor can detect whether the bone conduction headset 1 is worn or performs distance measurement by receiving the reflecting light. The low-beam sensor is, for example, an infrared low-beam sensor. The sensor assembly 17 may also include acceleration sensors, gravity sensors, touch sensors, and the like.
The bone conduction headset 1 and the intercom device 2 are in a Bluetooth connection state, when the sensor assembly 17 detects that the bone conduction headset 1 is worn, the bone conduction headset 1 in the bone conduction headset 1 and the intercom device 2 is controlled to be used for sound pickup and/or voice playing, and the intercom device 2 in the bone conduction headset 1 and the intercom device 2 is not used for sound pickup and/or voice playing. That is, when the bone conduction headset 1 is worn, the communication system is used for collecting sound through the microphone of the bone conduction headset 1 and/or playing voice through the speaker. When the sensor assembly 17 detects that the bone conduction headset 1 is not worn, the bone conduction headset 1 and the intercom device 2 in the intercom device 2 are controlled to pick up sound and/or play voice, and the bone conduction headset 1 in the bone conduction headset 1 and the intercom device 2 is not used for picking up sound and/or playing voice. That is, when the bone conduction headset 1 is not worn, the communication system is operated by the microphone of the intercom device 2 to pick up sound and/or operated by the speaker to play voice.
Based on the above description, when the bone conduction earphone 1 is not worn, if sound is picked up or voice is played through the bone conduction earphone 1, it may be impossible to effectively pick up sound or a user cannot hear voice transmitted by the bone conduction earphone 1, and at this time, sound can be picked up and/or voice is played through the intercom device 2, so that the played voice can be heard and/or effectively picked up. When the bone conduction headset 1 is worn, sound pickup and/or voice playing can be performed through the bone conduction headset 1, so that a user can conveniently send voice or hear the played voice. Whether detect bone conduction earphone 1 through sensor module 17 and be worn, and then the communication system of being convenient for realizes above-mentioned automatic switch-over, avoids speech information to be omitted, can adapt to different use scenes, improves work efficiency.

The first protrusion 1114 and the second protrusion 1115 formed on the bottom wall 1112 and the side wall 1113 are perpendicular to each other and arc-connected to each other, so that the structural strength and the structural stability of the first speaker housing 111 can be enhanced, the rotating member 114 is inserted into the first through hole 1110 of the first protrusion 1114, the first protrusion 1114 has a corresponding height, so that the rotation of the stick-microphone assembly 16 is not interfered by the first speaker housing 111, and the protruding directions of the first protrusion 1114 and the second protrusion 1115 are perpendicular to each other, so that the possibility of mutual interference between the ear-hook assembly 12 and the stick-microphone assembly 16 can be reduced.
In the present embodiment, the sound pickup assembly 162 may be connected to other related components of the bone conduction headset 1 through corresponding wire sets, such as the battery assembly 14 or the control circuit assembly 15, for transmitting the acquired audio signals to the related components for subsequent processing. The set of wires of the stick-microphone assembly 16 may be passed through the elastic cover 1613 of the elastic connecting rod 161 and exit via the connection 1612. The set of wires of the stick-microphone assembly 16 may be routed through the connection 1612 and into the first speaker housing 111. Specifically, the wire set of the stick-shaped tooth assembly 16 can be inserted into the first through hole 1110 and then inserted into the second through hole 1111 through the receiving space 110. The wire group of the stick-microphone assembly 16 can further pass through the ear-hook assembly 12 from the second through hole 1111 and enter the accommodating space 120, and is electrically connected to the battery assembly 14 or the control circuit assembly 15.
In practical use, the stick-microphone assembly 16 can rotate relative to the first speaker housing 111, which may cause the wire set of the stick-microphone assembly 16 to move, which may limit the rotation of the stick-microphone assembly 16 due to improper movement of the wire set, and the wire set may transmit the vibration of the speaker assembly 11 to the sound pickup assembly 162, thereby affecting the sound pickup effect of the sound pickup assembly 162, and possibly affecting the stability of the electrical connection.
As shown in fig. 7, the speaker assembly 11 may include a holding member 115 for holding the wire set of the stick-microphone assembly 16. Specifically, the pressing member 115 may be disposed in the accommodating space 110 and cover the first through hole 1110 for pressing the wire set of the stick-microphone assembly 16 passing through the first through hole 1110 to the second through hole 1111. Thus, the space of the wire group of the stick-microphone assembly 16 can be limited, the shaking or moving of the wire group can be reduced, the vibration generated by the vibration of the speaker assembly 11 and the vibration transmitted to the pickup assembly 162 can be reduced, the pickup effect of the pickup assembly 162 can be improved, the electrical stability can be improved, and in addition, the friction between the wire group and the first speaker housing 111 can be reduced by the pressing of the pressing member 115, so that the wire group can be protected. The receiving space 110 is formed after the first speaker housing 111 and the second speaker housing 112 are coupled, and the receiving space 110 is labeled at the first speaker housing 111 in fig. 7 only for ease of understanding and explanation. In addition, since the rotating member 114 is inserted into the first through hole 1110, the first through hole 1110 is occupied by the rotating member 114, and therefore, the first through hole 1110 is labeled at the rotating member 114 in fig. 7 for convenience of understanding and explanation.
The pressure holder 115 may include a rigid cover plate 1151 and an elastomer 1152 that are stacked. The hard cover 1151 is spaced apart from the first bore 1110 relative to the elastomer 1152, the elastomer 1152 is configured to contact the wire set of the club assembly 16, and the hard cover 1151 has a hardness greater than the elastomer 1152. The hard cover plate 1151 is in contact with the lead group through the pressing and holding elastic body 1152, the hardness of the hard cover plate 1151 is higher than that of the elastic body 1152, the hardness of the pressing and holding lead group can be guaranteed by the hard cover plate 1151 with the higher hardness, the absorption of movement or vibration of the lead group can be improved by the elastic body 1152 with the lower hardness, the vibration of the lead group is reduced, and the buffering and protecting effects are achieved.
Specifically, the first speaker housing 111 is provided with a plurality of studs 1117 protruding into the accommodating space 110 at the periphery of the first through hole 1110. The plurality of studs 1117 may be disposed at intervals around the first through hole 1110. The hard cover 1151 may be fixed to the plurality of studs 1117, and the elastomer 1152 may be disposed between the plurality of studs 1117. For example, the number of the convex pillars 1117 is three. Through setting up in the fixed stereoplasm apron 1151 of a plurality of projections 1117 of first through-hole 1110 peripheral, and then press the elastomer 1152 and hold the wire group of rod miaow subassembly 16, can improve stereoplasm apron 1151's stability, and then can improve the elastomer 1152 with the stability of wire group contact.
Optionally, the hard cover 1151 is a steel sheet and the elastomer 1152 is foam. Of course, the hard cover 1151 may be other materials, such as plastic, ceramic, etc., and the elastomer 1152 may be other materials, such as silicone, fiber, etc.
Based on the above description, by providing the pressing member 115 to press and hold the wire group of the stick-microphone assembly 16, it is possible to reduce the vibration of the wire group due to the vibration of the speaker assembly 11, to enhance the stability of the wire group of the stick-microphone assembly 16 during the rotation, and to protect the wire group of the stick-microphone assembly 16. In addition, the rotation of the stick-shaped member 16 also needs to have good stability, i.e. the engagement structure of the rotation member 114 and the first through hole 1110 plays a large role in the rotation stability of the stick-shaped member 16. The structure of the rotation member 114 is exemplarily described below.
As shown in fig. 8, the rotation member 114 may include a lead portion 1141 and a rotation portion 1142 connected to each other. The lead portion 1141 may be connected to the stick-microphone assembly 16. The rotating portion 1142 may be inserted into the first through hole 1110 and may rotate with respect to the first speaker housing 111. The wire set of the stick-microphone assembly 16 can enter the receiving space 110 through the lead portion 1141 and the rotating portion 1142. Specifically, the lead portion 1141 may be formed with a first hole segment 11410. The rotating portion 1142 may be formed with a second hole section 11420 in an axial direction thereof. The first bore section 11410 and the second bore section 11420 communicate. The patch section 1612 of the wand assembly 16 may be inserted into the first bore segment 11410 of the lead portion 1141. The wire set of the stick assembly 16 may be advanced into the receiving space 110 from the first aperture section 11410 and the second aperture section 11420. Alternatively, the angle between the direction of extension of the first bore section 11410 and the direction of extension of the second bore section 11420 may be less than 180 °. Optionally, the included angle is less than 150 °.
The rotating portion 1142 may include a rotating body 11421 and a first locking portion 11422 and a second locking portion 11423 provided to both ends of the rotating body 11421 to protrude in a radial direction of the rotating body 11421. Alternatively, the rotating body 11421 may be cylindrical, and a second hole section 11420 is opened along the axial direction thereof. Alternatively, the first and second latches 11422 and 11423 may be provided at the outer periphery of the rotating body 11421 in a ring shape or an open ring shape. Specifically, the first locking portion 11422 is farther from the lead portion 1141 than the second locking portion 11423, and the second locking portion 11423 is closer to the lead portion 1141 than the first locking portion 11422.
As shown in fig. 9, the rotating body 11421 may be fitted into the first through hole 1110, and the first locking portion 11422 and the second locking portion 11423 may abut against both sides of the first speaker housing 111, respectively, to restrict the movement of the rotating portion 1142 in the axial direction thereof. Specifically, the first locking portion 11422 and the second locking portion 11423 abut against both sides of the first speaker housing 111 through which the first through hole 1110 penetrates, that is, one side located inside the accommodating space 110 and the other side located outside the accommodating space 110, respectively. The first and second locking portions 11422 and 11423 provided at both ends of the rotating body 11421 abut against both sides of the first speaker housing 111, so that the movement of the rotating portion 1142 in the axial direction thereof can be effectively restricted, and the rotating portion 1142 is restricted in the first through hole 1110 to rotate, thereby enhancing the rotational stability thereof.
As shown in fig. 8 and 9, the rotating portion 1142 may be provided with a damping groove 1143 in order to further enhance the rotational stability of the stick-microphone assembly 16. Alternatively, the rotating body 11421 is formed with a damping groove 1143 between the first and second latches 11422 and 11423 in its circumferential direction. The speaker assembly 11 may include a damping member 116. The damping member 116 is disposed in the damping groove 1143 and contacts with the peripheral wall of the first through hole 1110 to provide rotational damping to the rotating portion 1142 by contact friction. The peripheral wall of the first through hole 1110, i.e., the bottom wall 1112, surrounds the portion of the first through hole 1110. Optionally, the damping member 116 is a rubber member, a plastic member or a silicone member. Of course, the damping member 116 may be other types of materials. By providing the damping member 116 to engage the damping groove 1143 to provide damping for the rotation of the rotating portion 1142 in the first through hole 1110, the rotation of the rotating portion 1142 can be made more stable, and the balance and stability of the rotation of the stick and microphone assembly 16 can be enhanced.
The rotation stability of the stick-microphone assembly 16 is also required to be enhanced, and if the stick-microphone assembly 16 can rotate in the same direction without limitation, the wire set of the stick-microphone assembly 16 may be twisted or broken, and the rotation in the same direction without limitation may cause the rotation member 114 of the rotation member 114 to be more easily disabled, which may make it difficult to adjust the angle of the stick-microphone assembly 16 using the rotation member 114. For this reason, the present embodiment can limit the range of rotation of the stick assembly 16 in the following manner.
As shown in fig. 8 and 9, the rotating portion 1142 may be formed with a limiting groove 1144, the peripheral wall of the first through hole 1110 may be protruded with a protrusion 1116, and the protrusion 1116 is used for the limiting groove 1144 to cooperate, so as to limit the rotating range of the rotating portion 1142.
Alternatively, the rotating body 11421 may be formed with a stopper groove 1144 between the first and second stoppers 11422 and 11423 in a circumferential direction thereof. The spacing groove 1144 and the damping groove 1143 may be spaced apart. Specifically, the limit groove 1144 and the damping groove 1143 are provided at an interval in the axial direction of the rotating body 11421. The retaining groove 1144 may be formed in an open loop, i.e., the angle occupied by the retaining groove 1144 is less than 360 °.
The peripheral wall of the first through hole 1110 may be protrudingly provided with a projection 1116 (also shown in fig. 6). The protrusion 1116 may be embedded into the limiting groove 1144, when the rotating portion 1142 rotates relative to the first speaker housing 111, two ends of the limiting groove 1144 may change positions with the rotation of the rotating portion 1142 and the protrusion 1116, and when the limiting groove 1144 rotates to an end thereof abuts against the protrusion 1116, the protrusion 1116 may limit the rotating portion 1142 to continue to rotate along the current rotation direction. That is, the protrusion 1116 may abut against both ends of the retaining groove 1144 to limit the rotation range of the rotating portion 1142.
The limiting groove 1144 arranged through the rotating main body 11421 is matched with the protruding block 1116 arranged on the peripheral wall of the first through hole 1110, the protruding block 1116 can be abutted to two ends of the limiting groove 1144, the rotating range of the rotating part 1142 is effectively limited, the stick microphone assembly 16 can rotate in a certain range, but the stick microphone assembly is not rotated towards the same direction without limitation, the rotating reliability of the stick microphone assembly 16 is improved, the fault probability of the stick microphone assembly 16 is reduced, and the service life of the bone conduction earphone 1 is prolonged.
As shown in fig. 8 and 9, in order to reduce the occurrence of the fact that the stick-microphone assembly 16 inserted into the first hole section 11410 is detached or torn out, etc., the speaker assembly 11 may include a fixing member 117 for fixing the stick-microphone assembly 16 inserted into the first hole section 11410 and restricting the movement of the stick-microphone assembly 16. Optionally, a securing aperture 160 may be provided at one end of the stick assembly 16 for insertion into the first aperture section 11410. Specifically, the fastener 117 may include a fastening body 1171 and a patch pin 1172 disposed at one end of the fastening body 1171. The fixing body 1171 is inserted into the second bore section 11420 and the plug 1172 is inserted into the fixing bore 160 to limit movement of the stick assembly 16. Specifically, the fixing body 1171 is also provided with corresponding lead holes 1170 along the length direction thereof to communicate the second hole segment 11420 with the receiving space 110, and the lead wires of the stick and microphone assembly 16 can pass through the corresponding lead holes 1170 of the fixing body 1171 and enter the receiving space 110.
A notch 11424 may be formed at an end of the rotating portion 1142 away from the lead portion 1141, and the notch 11424 may communicate with the second hole segment 11420. The fixing member 117 may include a boss 1173 protrudingly provided on the outer circumference of the fixing body 1171. Boss 1173 may be inserted into notch 11424 and supported within notch 11424. Thus, the supporting rotating body 11421 can be stably received in the second bore section 11420. Alternatively, the number of the notches 11424 is at least two, and divides one end of the rotating portion 1142 away from the lead portion 1141 into at least two sub-members 11425 spaced apart from each other in the circumferential direction of the rotating portion 1142. That is, the notch 11424 may penetrate through the circumferential side of the rotating body 11421, and further divide the end of the rotating portion 1142 away from the lead portion 1141 into a corresponding number of sub-members 11425 in the circumferential direction of the rotating portion 1142.
The end of the rotating part 1142 is divided into at least two sub-parts 11425 by the notch 11424, so that one end of the rotating part 1142 away from the lead part 1141 has certain elasticity, the difficulty of embedding the rotating part 1142 into the first through hole 1110 can be reduced, and the assembly efficiency is improved. Meanwhile, the boss 1173 is embedded into the notch 11424, and the structural reliability and strength of the rotating part 1142 are enhanced by the complementary mode of the boss 1173 and the notch 11424.
Optionally, the number of notches 11424 is two and are disposed opposite each other. The bosses 1173 are correspondingly two in number and are spaced apart from one another. The two bosses 1173 are correspondingly inserted into the two notches 11424 so that the fastener 117 is supported between the two sub-members 11425. Further, the two bosses 1173 are inserted into the two notches 11424, so that the fixing member 117 and the end of the rotating portion 1142 away from the lead portion 1141 are complementary to form a complete ring structure.
Based on the above description, the second through hole 1111 is used for the ear hook assembly 12 to be inserted and matched, and the wire set of the stick and microphone assembly 16 passes through the second through hole 1111 into the receiving space 120 of the ear hook assembly 12. The present embodiment is described below with respect to an ear hook assembly 12.
As shown in fig. 10 and 11, the earhook assembly 12 may include a first earhook housing 121, a connecting member 122, and a second earhook housing 123. One end of the connecting part 122 may be connected to the first earhook housing 121. The other end of the connection part 122 is connected to the speaker 113. For example, the other end of the connection member 122 is inserted into the second through hole 1111 of the first speaker housing 111 to be fitted with the speaker assembly 11. The first ear hook housing 121 and the second ear hook housing 123 can be connected in a matching manner to form an accommodating space 120 for accommodating the battery assembly 14 or the control circuit assembly 15. In this embodiment, the receiving space 120 of one of the ear hook assemblies 12 is used for receiving the battery assembly 14, such as the ear hook assembly 12 shown in fig. 10. The receiving space 120 of the other ear hook assembly 12 is used for receiving the control circuit assembly 15, such as the ear hook assembly 12 shown in fig. 11.
As shown in fig. 10, the battery assembly 14 may include a battery housing (not labeled) and a battery cell (not shown) disposed in the battery housing for storing electrical energy. The first NFC module 102 mentioned in the embodiment of the headset communication system of the present application may be attached to the battery assembly 14, for example, to a battery housing, so as to reduce the volume of the bone conduction headset 1, and also reduce electromagnetic interference or signal interference between the first NFC module 102 and the control circuit assembly 15.
As shown in fig. 11, the control circuit assembly 15 may include a circuit board 151, a power interface 152, a key 153, an antenna 154, and the like. The first bluetooth module 101 shown in fig. 2 may be integrated with the control circuit assembly 15. The control circuit assembly 15 may also be integrated with other circuits and elements. For example, the first bluetooth module 101 may be integrated on the circuit board 151. The sensor assembly 17 may also be integrated on the circuit board 151.
As shown in fig. 11, taking as an example the sensor assembly 17 comprising an optical sensor, the first earhook housing 121 may form a window 1200 for transmitting an optical signal of the optical sensor. The window 1200 may be disposed adjacent to the connection member 122 such that the window 1200 is proximate to a position adjacent to a root of an ear of the user when the bone conduction headset 1 is worn. Optionally, window 1200 is disposed in a racetrack shape. Alternatively, the extension line of the central axis of the connecting member 122 intersects the long axis of the window 1200, as schematically shown in fig. 11 in a rough intersecting relationship. By arranging that the extension line of the central axis of the connecting part 122 intersects with the long axis of the window 1200, the window 1200 can be effectively close to the position of the user near the root of the ear, and the sensitivity of the sensor assembly 17 and the detection effectiveness can be ensured. Specifically, the first earhook housing 121 of the earhook assembly 12 for accommodating the control circuit assembly 15 may form the window 1200 described above.
The development trend of the bone conduction earphone 1 is toward lightness and miniaturization, and the ear hook assembly 12 is used for accommodating the battery assembly 14 or the control circuit assembly 15 and related wires, which is often a place where the bone conduction earphone 1 has a large volume, and the design of the related fastening position and fastening structure in the ear hook assembly 12 affects the volume of the whole ear hook assembly 12. To reduce the volume of the earhook assembly 12, the present embodiment provides a housing structure for the earhook assembly as follows.
The first earhook housing 121 can be formed with a first locking groove 1211 and a second locking groove 1212 which are disposed at an interval, the second earhook housing 123 can be formed with a first locking block 1231 and a second locking block 1232 which are disposed at an interval, the first locking groove 1211 and the first locking block 1231 can be in clamping fit, the second locking groove 1212 and the second locking block 1232 can be in clamping fit, and thus the first earhook housing 121 and the second earhook housing 123 can be in clamping fit.
Specifically, the accommodating space 120 may have a length direction and a thickness direction perpendicular to each other. In the following description, unless otherwise noted, the length direction refers to the length direction of the accommodating space 120, and the thickness direction refers to the thickness direction of the accommodating space 120.
As shown in fig. 12 and 13, the first earhook housing 121 and the second earhook housing 123 are spliced to each other along a splicing direction perpendicular to the length direction and the thickness direction, thereby forming the accommodating space 120. For example, the first earhook housing 121 has a first sub-receiving space 1210, the second earhook housing 123 has a second sub-receiving space 1230, and after the first earhook housing 121 and the second earhook housing 123 are spliced, the first sub-receiving space 1210 and the second sub-receiving space 1230 are combined to form the receiving space 120.
The first earhook housing 121 may be formed with a first card slot 1211 and a second card slot 1212 having the same opening direction at intervals along the length direction. That is, the openings of the first card slot 1211 and the second card slot 1212 face in the same direction. The second earhook housing 123 is provided with a first latching block 1231 and a second latching block 1232 protruding in the same extending direction along the length direction. That is, the first and second latching blocks 1231 and 1232 are spaced apart from each other in the longitudinal direction, and the protruding directions of the first and second latching blocks 1231 and 1232 are the same, so that the first and second latching blocks 1231 and 1232 can be respectively inserted into the first and second latching grooves 1211 and 1212 in the same direction.
As shown in fig. 14, the first latching block 1231 can be inserted into the first latching groove 1211, and the second latching block 1232 can be inserted into the second latching groove 1212, so as to limit the relative movement between the first earhook housing 121 and the second earhook housing 123 in the mating direction and the thickness direction.
The mating edge 1201 of the first earhook housing 121 and the mating edge 1202 of the second earhook housing 123 can be engaged with each other to restrict the relative movement of the first earhook housing 121 and the second earhook housing 123 in the longitudinal direction. In the present embodiment, the first earhook housing 121 and the second earhook housing 123 are joined together, which means that the joined edge 1201 of the first earhook housing 121 and the joined edge 1202 of the second earhook housing 123 are substantially in contact and connected. The splicing edge 1201 of the first earhook housing 121 may refer to an edge of the first earhook housing 121 facing the second earhook housing 123 for splicing with the second earhook housing 123, such as the splicing edge 1201 shown in fig. 12. Similarly, the joint edge 1202 of the second earhook housing 123 can refer to the edge of the second earhook housing 123 facing the side of the first earhook housing 121 for joining with the first earhook housing 121, such as the joint edge 1202 shown in fig. 13.
For example, the shape of the joint edge 1201 of the first earhook housing 121 and the shape of the joint edge 1202 of the second earhook housing 123 are adapted to fit or complement each other, thereby forming a stable fitting structure that can limit the relative movement of the two in the longitudinal direction.
For the first and second clips 1231 and 1232 extending in opposite directions, the first and second clips 1231 and 1232 protrude in opposite directions, which inevitably results in an increase in the space occupied by the first and second clips 1231 and 1232, and the first and second clip grooves 1211 and 1212 need to have an increased distance in the length direction to cover the first and second clips 1231 and 1232, respectively, whereas the first and second clip grooves 1211 and 1212 having the same opening direction and the first and second clip grooves 1231 and 1232 having the same extending direction are provided in the present embodiment, so that the fitting directions of the first and second clip grooves 1231 and 1232 and the first and second clip grooves 1211 and 1212 having the same opening direction are the same, and since the extending directions of the first and second clip grooves 1231 and 1232 are the same, the additional volume occupied by the first and second clip blocks 1231 and 1232 can be reduced, furthermore, the volume occupied by the first and second retention blocks 1231, 1232 and the first and second retention grooves 1211, 1212 in cooperation can be reduced, which effectively reduces the volume of the earhook assembly 12, and in addition, by engaging the engaging edge 1201 of the first earhook housing 121 and the engaging edge 1202 of the second earhook housing 123 with each other, there is no need to provide additional structure such as a buckle or a protrusion, which makes the structure of the earhook assembly 12 more compact and also reduces the volume of the earhook assembly 12. Meanwhile, the first and second clamping blocks 1231, 1232 can be matched with the first and second clamping grooves 1211, 1212 to limit the displacement in the splicing direction and the thickness direction, and the splicing edges 1201, 1202 can be matched to limit the displacement in the length direction, so that the first and second earhook housings 121, 123 can be spliced more stably, and the structure is more reliable.
As shown in fig. 12, the first card slot 1211 and the second card slot 1212 may be respectively located at two sides of the first earhook housing 121 along the length direction, the opening direction of the first card slot 1211 faces the accommodating space 120, and the opening direction of the second card slot 1212 faces away from the accommodating space 120. That is, the opening direction of the first card slot 1211 faces the first sub-receiving space 1210, and the opening direction of the second card slot 1212 faces away from the first sub-receiving space 1210. Optionally, the first card slot 1211 is opened on a side of the first earhook housing 121 close to the connecting part 122, and the second card slot 1212 is opened on a side of the first earhook housing 121 far from the connecting part 122.
As shown in fig. 13, the first latching block 1231 and the second latching block 1232 can be respectively located at two sides of the second earhook housing 123 along the length direction, the extending direction of the first latching block 1231 deviates from the accommodating space 120, and the extending direction of the second latching block 1232 faces into the accommodating space 120. That is, the extending direction of the first latching 1231 deviates from the second sub-receiving space 1230, and the extending direction of the second latching 1232 faces the second sub-receiving space 1230. Accordingly, the first latching block 1231 is disposed on a side of the second earhook housing 123 close to the connecting part 122, and the second latching block 1232 is disposed on a side of the second earhook housing 123 far from the connecting part 122. Because the second latching block 1232 extends to the inside of the accommodating space 120 in a protruding manner, compared with the extending to the outside of the accommodating space 120, the second latching block 1232 does not need to occupy extra space, so that the corresponding space can be saved, and the second latching groove 1212 is located in front of the extending direction of the second latching block 1232 when being engaged, and the two are engaged with each other in an embedded manner, so that the volume of the ear hook assembly 12 can be reduced.
The joint edge 1201 of the first earhook housing 121 is provided with a first stopper 1213, the joint edge 1202 of the second earhook housing 123 is provided with a second stopper 1234, and the first stopper 1213 and the second stopper 1234 are fitted to each other to restrict the relative movement of the first earhook housing 121 and the second earhook housing 123 in the length direction. For example, the first stopping portion 1213 is an opening formed by the joint edge 1201 of the first earhook housing 121, and the second stopping portion 1234 is a protrusion formed by the joint edge 1202 of the second earhook housing 123, and the opening and the protrusion are adapted to fit each other, so that the joint edge 1201 of the first earhook housing 121 and the joint edge 1202 of the second earhook housing 123 can be complementary to each other to limit the relative movement therebetween in the length direction.
The opening direction of the first card slot 1211 faces the accommodating space 120, if the first card slot 1211 is directly formed in the first sub-accommodating space 1210, in the process of forming the first sub-accommodating space 1210 and the first card slot 1211 by using corresponding molds, the mold drawing direction for forming the first sub-accommodating space 1210 and the mold drawing direction for forming the first card slot 1211 may interfere with each other, and since the mold drawing direction of the first card slot 1211 is in the first sub-accommodating space 1210, the mold drawing direction may also conflict with the mold drawing directions of other structures, which brings great difficulty in production. Based on the technical problem, the following structure is designed in the embodiment to reduce the production and manufacturing difficulty.
As shown in fig. 15, the first earhook housing 121 can be opened with an outer hole section 1215 and an inner hole section 1216 communicating with each other in a direction from the outside of the accommodating space 120 to the inside of the accommodating space 120. That is, the outer hole section 1215 opens away from the receiving space 120, the inner hole section 1216 opens toward the receiving space 120, and the outer hole section 1215 communicates with the inner hole section 1216. Outer bore section 1215 is filled with filler 1217. The filler 1217 is, for example, a rubber member, such as a hard rubber. After the outer hole section 1215 is filled and sealed, the inner hole section 1216 can be used as a first locking groove 1211, and the opening direction of the inner hole section 1216 faces the accommodating space 120, and can be matched with the first locking block 1231.
In an actual manufacturing process, an outer hole section 1215 and an inner hole section 1216 may be sequentially formed from the outside of the first earhook housing 121 to the inside of the first earhook housing 121, and the mold drawing direction is not performed in the first sub-receiving space 1210, but outside the first earhook housing 121, and then the filling member 1217 is used to fill the outer hole section 1215, so that the remaining inner hole section 1216 may be used as the first slot 1211, thereby effectively reducing the manufacturing difficulty and complexity and saving the cost.
The cross-sectional area of outside bore segment 1215 perpendicular to the direction of communication between outside bore segment 1215 and inside bore segment 1216 is greater than the cross-sectional area of inside bore segment 1216 perpendicular to the direction of communication between outside bore segment 1215 and inside bore segment 1216. Since the corresponding cross-sectional area of outer bore section 1215 is greater than the corresponding cross-sectional area of inner bore section 1216, it is convenient to fill filler 1217 in outer bore section 1215, which can provide a better sealing effect, and thus can form first locking groove 1211 more quickly.
Based on the above structural description of the outboard and inboard aperture sections 1215, 1216 of the ear hook assembly 12, the present embodiment can exemplarily describe the method of manufacturing the ear hook assembly 12 as follows:
s100: the first and second earhook housings 121 and 123 are formed by injection molding, and an outer hole section 1215 and an inner hole section 1216 communicating with each other are formed in the first earhook housing 121 from the outside of the first earhook housing 121 to the inside of the first earhook housing 121, and a first latching block 1231 is formed on the second earhook housing 123.
S200: filler 1217 is inserted into outer bore section 1215 and utilizes inner bore section 1216 as a first catch 1211.
Optionally, a filler 1217 is inserted into outer bore section 1215 by injection molding.
In order to protect the first earhook housing 121, the first earhook housing 121 may be coated with an earhook elastic coating 1223 after S200, as follows:
s210: an earhook elastic coating 1223 is injection molded around the first earhook housing 121 and covers the outer bore segment 1215.
S300: the first engaging groove 1211 and the first engaging block 1231 are engaged to engage the first earhook housing 121 and the second earhook housing 123.
The molding method and steps in other structures of the ear hook assembly 12 can be manufactured by using the existing molding method based on the specific structure of the ear hook assembly 12, and are not described herein again.
In order to reduce the volume of the ear-hook assembly 12, the positions of the components in the accommodating space 120 can be replaced or reset, so that the accommodating space 120 can be effectively compressed, and the volume of the ear-hook housing can be reduced. If the power jack 1233, etc. of the bone conduction headset 1 is disposed on the side of the second earhook housing 123 away from the bottom wall 1112 of the first earhook housing 121, the volume of the earhook assembly 12 is increased. In order to effectively reduce the volume of the ear hook assembly 12, the power jack 1233 is disposed on the side wall 1113 of the second ear hook housing 123 far away from the connecting component 122, which can be described in detail as follows:
as shown in fig. 12-14, a power jack 1233 is disposed on a portion of the second earhook housing 123 away from the connecting member 122. The power jack 1233 is connected to the accommodating space 120, and the power jack 1233 is used for accommodating the power interface 152. For example, the second earhook housing 123 may also have a housing bottom and a housing side, the housing side is connected around the housing bottom to form the second sub-receiving space 1230. The side edges of the housing sides remote from the housing bottom serve as the mating edges 1202 for mating with the first earhook housing 121. The power jack 1233 is disposed on the side of the housing and is connected to the second sub-receiving space 1230, i.e. the receiving space 120.
As shown in fig. 14, the second latch 1232 is disposed adjacent to the power jack 1233. That is, the second latch 1232 is protruded from a portion of the second earhook housing 123 away from the connecting member 122 and faces the accommodating space 120. In the embodiment, the second latch 1232 is closer to the accommodating space 120 than the power jack 1233. In other words, the second latch 1232 is closer to the connection member 122 than the power jack 1233.
Alternatively, the projections of the second latch 1232 and the power jack 1233 on the first reference plane perpendicular to the longitudinal direction overlap each other. In the present embodiment, overlapping each other includes partially overlapping (i.e., the overlapped portion is a portion of the projection of the second fixture 1232 and is also a portion of the projection of the power jack 1233), and also includes completely overlapping (i.e., the projection of the second fixture 1232 completely falls within the projection of the power jack 1233). Alternatively, a plane perpendicular to the longitudinal direction is used as the first reference plane, and the projection of the second fixture 1232 on the first reference plane is located within the projection of the power jack 1233 on the first reference plane, that is, the projection ranges of the two are all overlapped. The positions of the second latch 1232 and the power jack 1233 are set such that the structure of the second earhook housing 123 is compact without affecting the installation of the power interface 152, thereby reducing the volume of the earhook assembly 12.
Alternatively, the projections of the second latch 1232 and the power jack 1233 on the second reference plane perpendicular to the mating direction overlap each other. Here, the overlapping includes partial overlapping and full overlapping. Alternatively, a plane perpendicular to the splicing direction is used as the second reference plane, and the projection of the second fixture 1232 on the second reference plane is also located in the projection of the power jack 1233 on the second reference plane, that is, the projection ranges of the two are also all overlapped. Therefore, the second clamping block 1232 and the power jack 1233 are arranged compactly in the splicing direction or the length direction, and the space occupied by the power jack 1233 and the second clamping block 1232 can be greatly saved, so that the structural compactness of the ear hook assembly 12 is improved.
In addition, using bone conduction headset 1 in the production manufacturing field such as industry, having very big requirement for bone conduction headset 1's the control experience, seting up power jack 1233 in the part casing that second supra-aural casing 123 is kept away from adapting unit 122 can improve bone conduction headset 1's operation experience for the following reason:
the bone conduction earphone 1 generally has a volume button, etc. according to the conventional means, the button hole 1235 and the power jack 1233 corresponding to the button 153, etc. generally open the bottom of the second earhook housing 123, i.e. the part of the second earhook housing 123 away from the first earhook housing 121. Because the area of the bottom of the housing is relatively limited, the space between the key hole 1235 and the power jack 1233 is relatively compact, and the key hole 1235 and the power jack 1233 occupy as little space as possible. In the production and manufacturing fields such as industry, a wearer may wear a work clothes or gloves, the key holes 1235 are small, the arrangement is too compact, the operation experience of the wearer is reduced, and misoperation is easily caused. And this embodiment does not set up power jack 1233 on the casing bottom, but sets up power jack 1233 on the casing lateral part, so the size of key hole 1235 can be designed great, arrange each other can be comparatively loose, so can convenient to use person operate, reduce the emergence of mistake control.
Furthermore, based on the design of the power jack 1233, if the second fixture block 1232 is disposed at the top position of the second earhook housing 123, which is adjacent to the power jack 1233 and faces the first earhook housing 121 (as shown in fig. 13, the platform region connecting the second fixture block 1232, that is, the second fixture block 1232 can be regarded as extending from the platform region to the second sub-receiving space 1230), the space of the plug hole 1218 of the first earhook housing 121 is squeezed, which may affect the plug-fit between the earhook assembly 12 and the rear-hook assembly 13, the second fixture block 1232 needs to occupy extra space, which may cause the first earhook housing 121 and the second earhook housing 123 to occupy a larger space in the splicing direction, which is not compact enough, therefore, the present embodiment arranges the power jack 1233 at the housing bottom of the second earhook housing 123, and arranges the structural relationship between the second fixture block 1232 and the power jack 1233 in the above-mentioned projection relationship, the second ear hook housing 123 is more compact in structure in the splicing direction, and the second fixture block 1232 extends toward the inside of the accommodating space 120, so that the space does not need to be additionally occupied, and the volume of the ear hook housing 12 can be further miniaturized.
Based on the above detailed description, the stable splicing structure between the first earhook housing 121 and the second earhook housing 123 can protect the battery assembly 14 and the control circuit assembly 15 in the accommodating space 120. Of course, in order to reduce the failure rate of the bone conduction headset 1, it is necessary to ensure not only the structural stability but also the stability of the electrical connection. The internal lead group of the bone conduction earphone 1 is wired between the loudspeaker component 11 and the ear-hang component 12, and the stability of the wiring is related to the reliability of the bone conduction component. To improve the reliability of the wiring, the ear hook assembly 12 may be provided with a corresponding wire-clamping structure to ensure the stability of the wires when the wire group passes through the ear hook assembly 12, which is specifically described below.
The connection member 122 may include an earhook elastic wire 1221 and a connector portion 1222 connected to one end of the earhook elastic wire 1221. In order to protect the ear-hook elastic wire 1221, the connecting member 122 may also include an ear-hook elastic coating 1223 that covers at least the outer periphery of the ear-hook elastic wire 1221 (see fig. 12). Of course, the earhook elastic wire 1221 may further cover the first earhook housing 121. The connector 1222 is for mating with the speaker assembly 11. The other end of the earhook elastic wire 1221 is connected to the first earhook housing 121.
As shown in fig. 15 and 16, the connector 1222 has a first wire clamping portion 1224, the first ear hook housing 121 has a second wire clamping portion 1219, the lead group led out through the speaker module 11 can enter the accommodating space 120 through the first wire clamping portion 1224 and the second wire clamping portion 1219 in sequence, and the first wire clamping portion 1224 and the second wire clamping portion 1219 are used for locking the lead group in the radial direction of the lead group, so that the radial play of the lead group can be reduced.
The lead group to which the first wire clamping portion 1224 and the second wire clamping portion 1219 are fastened may be an additional member such as an auxiliary titanium wire used in the production process of the ear hook module 12. Specifically, in the preparation process of the ear hook assembly 12, an auxiliary titanium wire needs to be used to form a lead channel in the ear hook elastic coating 1223, so that the auxiliary titanium wire sequentially passes through the first wire clamping portion 1224, the second wire clamping portion 1219 and enters the accommodating space 120 in the preparation process, and after the preparation is completed, the auxiliary titanium wire is pulled out to form the lead channel communicating the accommodating space 110 and the accommodating space 120. The first wire clamping portion 1224 and the second wire clamping portion 1219 can keep the stability of the auxiliary titanium wire, reduce the wobbling of the auxiliary titanium wire, so that the glue site can be more stable.
Alternatively, the lead channels may be juxtaposed with the earring spring wire 1221 within the earring spring coating 1223.
The lead group to which the first wire clamping portion 1224 and the second wire clamping portion 1219 are locked may be a lead group to be electrically connected to each other through which a lead passage is formed. That is, the lead wire set led out through the speaker module 11 enters the accommodating space 120 through the first wire clamping portion 1224 and the second wire clamping portion 1219. Specifically, the wire group needs to reduce the shaking before and after entering the lead channel, so that the lead efficiency can be improved. In addition, since the ear hook assembly 12 is generally disposed in an arc shape for being hooked on the ear of a person, the wire group passing through the ear hook assembly 12 is likely to be shaken or moved, and the first wire clamping portion 1224 and the second wire clamping portion 1219 can reduce the shaking of the wire group.
Specifically, the ear-hang elastic coating 1223 is formed with a wire passage (not shown). The lead group led out from the speaker assembly 11 can enter the accommodating space 120 through the first wire clamping part 1224, the lead channel and the second wire clamping part 1219 in sequence. In this embodiment, if the speaker assembly 11 is also connected with the stick-microphone assembly 16, the set of wires led out through the speaker assembly 11 may include the set of wires of the speaker 113 and the set of wires of the stick-microphone assembly 16. If the speaker assembly 11 is not connected to the stick-microphone assembly 16, the set of wires leading out through the speaker assembly 11 comprises the set of wires for the speaker 113.
In this embodiment, the first wire clamping portion 1224 and the second wire clamping portion 1219 are respectively disposed on the connector 1222 and the first ear-hook housing 121, on one hand, the auxiliary titanium wire can be clamped in the preparation process to move relative to the first ear-hook housing 121 and the connector 1222, the glue position of the ear-hook assembly 12 is more uniform, the yield is improved, on the other hand, the movement of the wire group in the radial direction can be clamped, and further the shaking generated by the wire group is reduced, so that the threading efficiency of the wire group is higher, and also the structure of the wire group in an actual product can be more stable, and further the stability of electrical connection can be ensured.
Specifically, the first wire clamping portion 1224 may have two first wire clamping portions 12241 arranged at intervals in the thickness direction. As shown in fig. 16, the two first daughter card wire portions 12241 are offset from each other in the length direction of the lead group. The two first sub-wiring portions 12241 may lock the lead group in the thickness direction when the lead group passes between the two first sub-wiring portions 12241, and may restrict movement of the lead group in the thickness direction. Optionally, the two first daughter card wire portions 12241 extend differently in the length direction of the lead group.
The second card line portion 1219 may have two second sub card line portions 12191 arranged at intervals in the thickness direction, the two second sub card line portions 12191 being disposed opposite to each other. The two second sub-card wire portions 12191 can lock the group of leads in the thickness direction when the group of leads passes between the two second sub-card wire portions 12191, and thus can restrict the movement thereof in the thickness direction.
In addition, the first wire clamping portion 1224 may be recessed from the connector portion 1222, and the second wire clamping portion 1219 may be recessed from the first earhook housing 121, such that the wire set may be seen through the first wire clamping portion 1224 and the second wire clamping portion 1219, which may further reduce the distance that the wire set is threaded in the invisible area, facilitate the threading of the wire set, and improve the threading efficiency.
In order to facilitate the insertion of the connector 1222 into the second through hole 1111 of the first speaker housing 111 and to enhance the connection stability therebetween, as shown in fig. 16, an end 12221 of the connector 1222 may be formed with two through grooves 1225 crossing each other to divide the end 12221 into four sub-ends. By dividing the end 12221 into four sub-ends by providing two through grooves 1225 that intersect each other, the elasticity of the end 12221 can be enhanced, so that the four sub-ends can be pressed and elastically restored, and thus when the joint 1222 is inserted into the second through hole 1111, the four sub-ends are pressed to be close to each other, so that the end 12221 becomes small and the joint 1222 is easily inserted into the second through hole 1111.
The outer circumference of the sub-end may be protrudingly provided with a projection 1226. The connector 1222 is inserted into the speaker assembly 11 and the protrusion 1226 is stopped and limited by the speaker assembly 11 to limit the movement of the connector 1222 away from the speaker assembly 11. Specifically, after the connector 1222 is inserted into the second through hole 1111, the four sub-ends elastically recover, so that the protrusion 1226 at the outer periphery of the sub-end is retained and limited by the speaker assembly 11, thereby improving the connection reliability between the ear hook assembly 12 and the speaker assembly 11.
Specifically, the tab 1222 is inserted into the second through hole 1111, the protrusion 1226 may be located in the receiving space 110, and the protrusion 1226 is caught at an edge of a communication portion between the second through hole 1111 and the receiving space 110.
The material of the ear-hanging elastic wire 1221 may be spring steel, titanium, other metal or non-metal material. The material of the ear-hanging elastic coating 1223 may be silicone, rubber, plastic, etc., or other materials. The ear-hook elastic coating 1223 covers the ear-hook elastic wire 1221, and may further cover the first ear-hook housing 121 and the second ear-hook housing 123, and may cover the second wire-clamping portion 1219. Of course, the power jack 1233 and the like may be exposed. The ear hook elastic coating 1223 may also coat at least a portion of the tab portion 1222 and may cover the first wire engaging portion 1224.
As shown in fig. 17, the rear hanging assembly 13 may include a rear hanging elastic wire 131, a rear hanging elastic coating 132 coated on the rear hanging elastic wire 131, and insertion portions 133 disposed at both ends of the rear hanging elastic wire 131. The rear hanging elastic coating 132 may also coat at least a portion of the insertion portion 133.
The insertion portion 133 is for mating with the ear hook assembly 12. Specifically, a side of the first earhook housing 121 away from the connecting component 122 is opened with a patch hole 1218 communicated with the accommodating space 120. The patch hole 1218 is disposed adjacent to the second card slot 1212. The insertion portion 133 may be mateable with a patch hole 1218. At least one insertion part 133 is provided with two sets of slots 1331 at intervals in the length direction thereof. That is, at least one insertion portion 133 has two sets of slots 1331 spaced apart in the longitudinal direction of the insertion portion 133, and each set of slots 1331 includes at least one slot 1331. The rear hanging elastic wire 131 is inserted into the insertion part 133 through one end of the insertion part 133. One set of slots 1331 is adjacent to the insertion portion 133 and the other set of slots 1331 is distal to an end of the insertion portion 133.
Alternatively, the insertion portion 133 has two sets of slots 1331 opened in the direction from one end of the insertion portion 133 to the other end of the insertion portion 133 in sequence. A slot 1331 near one end of the insert 133 is used for mold positioning. A slot 1331 at an end distal from the insertion portion 133 is for snap-fit engagement with the first earhook housing 121.
For example, the two sets of slots 1331 are divided into a first set of slots 1331 and a second set of slots 1331, the first set of slots 1331 being distal from the insertion portion 133 and being adapted to snap-fit with the earhook assembly 12. As shown in fig. 17 and 18, the first earhook housing 121 is protrusively provided with a click portion 12181. For example, a snap portion 12181 protrudes into the patch hole 1218 of the first earhook housing 121. The insertion portion 133 is inserted into the insertion hole 1218, and the engaging portion 12181 is inserted into the first slot 1331, so as to limit the relative movement between the ear-hook assembly 12 and the rear-hook assembly 13.
The second slot 1331 is near one end of the insert 133 and is used for mold positioning. That is, the second set of slots 1331 is used for matching with corresponding protruding structures on the mold, so as to accurately fix the inserting part 133 at a certain position, and further perform other processes on the inserting part, thereby improving the yield. The insertion portion 133 and the rear suspension spring wire 131 are positioned by, for example, the second set of slots 1331, and the rear suspension spring coating 132 may be formed by injection molding.
Alternatively, the slots 1331 may extend from the edges of the insertion portion 133 located at both sides of the central axis toward the central axis. Each set of slots 1331 includes two slots 1331, with the two slots 1331 of each set being disposed opposite each other.
The above description is only an example of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings, or which are directly or indirectly applied to other related technical fields, are intended to be included within the scope of the present application.
