Description

Technical Field

[0001] The present invention relates to the technical field of speaker boxes, and in particular to a mobile terminal conference speaker box. Background Art

[0002] Mobile phones are used more and more widely and have become an essential tool for modern people. People's requirements for their functions are increasing, from simple two-party conversations to multi-party talks requiring the participation of third parties, and even the function requirements of mobile phone conferences.

[0003] In the prior art, most models of mobile phones have a hands-free function, and people can use the hands-free function of mobile phones to conduct multi-party talks. However, because the power of the built-in speaker of the mobile phone is limited, the sound volume is low, and various interference signals will be received by the built-in microphone of the mobile phone, thereby interfering with the transmission of sound. Therefore, when there are more than three people in the meeting, whether it is receiving or sending audio signals, the sound effect is poor or even inaudible. In addition, since the sound output direction of the mobile phone speaker is single, the meeting personnel who are not in the direction of the speaker output cannot hear clearly.

[0004] There are also Bluetooth speakers on the market, but when using Bluetooth speakers, you need to carry an additional power cord to recharge the speaker. Since Bluetooth speakers are large in size and require a power cord, they are inconvenient to carry.

[0005] In addition, during the meeting, there is a need to view the mobile phone screen. Without a stand, it needs to be held manually, which is very inconvenient to use during a multi-person meeting.

[0006] Therefore, it is urgent to develop a mobile phone conference speaker to solve the problem of the single sound direction of the speaker. Summary of the invention

[0067] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0068] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions, and the first feature "above", "above" and "above" the second feature include the first feature being directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. The first feature "below", "below" and "below" the second feature include the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0069] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0070] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0071] In the prior art, most models of mobile terminals have a hands-free function, and people can use the hands-free function of the mobile terminal to conduct multi-party talks. However, because the built-in speaker of the mobile terminal has limited power, the sound volume is low, and various interference signals will be received by the built-in microphone of the mobile terminal, thereby interfering with the transmission of sound. Therefore, when the number of people in the meeting is more than three, whether it is the reception or transmission of the audio signal, the sound effect is poor, or even inaudible, and because the sound output direction of the speaker of the mobile terminal is single, the meeting personnel who are not in the direction of the speaker cannot hear clearly. There are also Bluetooth speakers on the market, but when using Bluetooth speakers, you need to carry an additional power cord to supplement the power of the speaker. Since the Bluetooth speaker is large in size and requires a power cord, it is inconvenient to carry. In addition, during the meeting, there is also a need to watch the screen of the mobile terminal. In the absence of a bracket, it needs to be manually held, which is very inconvenient to use during a multi-person meeting.

[0072] To solve the problem of the single sound direction of the above-mentioned speaker, refer to Figure 1-12As shown, this embodiment provides a mobile terminal conference speaker, which includes a shell 1, a flip component 2, a connector 3, a first speaker 4, a second speaker 5 and a detection component 6, wherein one end of the flip component 2 is connected to the shell 1; the connector 3 is arranged at the other end of the flip component 2, and is configured to be plugged and communicatively connected with the mobile terminal 100, and the flip component 2 is configured to enable the shell 1 to rotate between a first position that fits the screen of the mobile terminal 100 and a second position that fits the back of the mobile terminal 100; the first speaker 4 is arranged on the front side of the shell 1, and is configured to amplify the sound of the mobile terminal 100; the second speaker 5 is arranged on the back side of the shell 1, and is configured to amplify the sound of the mobile terminal 100; the detection component 6 is arranged on the shell 1, and is configured to detect the position of the shell 1, when the shell 1 is in the first position, the second speaker 5 works; when the shell 1 is in the second position, the first speaker 4 works; when the shell 1 is in a third position between the first position and the second position, the first speaker 4 and the second speaker 5 work simultaneously. With the above settings, the sound of the mobile terminal 100 can be amplified in three ways. Specifically, the sound of the mobile terminal 100 can be amplified by the first speaker 4 or the second speaker 5 or the first speaker 4 and the second speaker 5 at the same time, which can meet different conference requirements. For example, when only one or two people participate in a video or audio conference in front of the screen of the mobile terminal 100, the housing 1 can be placed in the first position or the second position, and the first speaker 4 or the second speaker 5 can be used to amplify the sound of the mobile terminal 100. When there are more people who need to surround the mobile terminal 100, the housing 1 can be placed in the third position. At this time, the first speaker 4 and the second speaker 5 amplify the sound of the mobile terminal 100 at the same time, and due to the existence of the flip component 2, the housing 1 and the mobile terminal 100 set at an angle can be placed sideways on the desktop. At this time, the propagation directions of the first speaker 4 and the second speaker 5 are both horizontal and opposite, and the sound in the meeting can be clearly transmitted to the people around the mobile terminal 100.

[0073] Of course, in the above embodiment, both the first speaker 4 and the second speaker 5 can only unidirectionally loudspeaker, and optionally, the first speaker 4 and the second speaker 5 can be integrated into one. In another embodiment, the first speaker 4 can be a speaker with double-sided loudspeaker, and when working, it can loudspeak on one side or both sides. In this embodiment, the second speaker 5 can be directly abandoned, and the double-sided loudspeaker effect can also be achieved. In other embodiments, the first speaker 4 and the second speaker 5 can both be speakers with double-sided loudspeaker, so as to provide better stereo sound. Preferably, when the housing 1 is placed in the third position, the first speaker 4 and the second speaker 5 simultaneously amplify the sound of the mobile terminal 100 through both sides, and when the housing 1 is placed in the first position or the second position, the amplified sound is only emitted from the side of the speaker away from the mobile terminal 100 away from the mobile terminal.

[0074] In this embodiment, the mobile terminal 100 can be a mobile phone or a tablet computer. In each of the figures, the mobile terminal 100 is in the form of a mobile phone. It should be noted that the mobile terminal conference speaker also includes a controller, which is in communication connection with the detection component 6, the first speaker 4 and the second speaker 5. When the controller receives the position signal of the housing 1 detected by the detection component 6, the first speaker 4 and / or the second speaker 5 is controlled to work. In particular, the controller is arranged in the control unit 300, and when the control unit 300 is a circuit board, the controller is arranged on the circuit board.

[0075] Among them, when the angle between the housing 1 and the mobile terminal 100 is about 90 degrees or about 270 degrees, the housing 1 can be used as a bracket of the mobile terminal 100, and the mobile terminal 100 can be stood up. In particular, when the housing 1 is located at the rear side of the mobile terminal 100, that is, when the angle between the housing 1 and the mobile terminal 100 is greater than 180 degrees, the housing 1 will not block the screen of the mobile terminal 100, and the user can watch the content of the movie or conference presentation through the screen of the mobile terminal 100, and have a better user experience.

[0076] Regarding the structure of the detection component 6, in this embodiment, optionally, the detection component 6 includes a first detection component 61 and a second detection component 62, the first detection component 61 is arranged on the front side of the shell 1, and the first detection component 61 is configured to detect the shell 1 located at the first position, and the second detection component 62 is arranged on the back side of the shell 1, and the second detection component 62 is configured to detect the shell 1 located at the second position.

[0077] Specifically, the controller is in communication connection with the first detection member 61 and the second detection member 62. Regarding the specific structure of the first detection member 61, in this embodiment, optionally, the first detection member 61 can be an infrared sensor. When the housing 1 and the screen of the mobile terminal 100 are attached, the first detection member 61 is blocked. At this time, the first detection member 61 sends a detection signal, and the controller controls the second speaker 5 to work. Regarding the specific structure of the second detection member 62, in this embodiment, optionally, the second detection member 62 can be an infrared sensor. When the housing 1 and the back of the mobile terminal 100 are attached, the second detection member 62 is blocked. At this time, the second detection member 62 sends a detection signal, and the controller controls the first speaker 4 to work.

[0078] Of course, in other implementations of this embodiment, the first detection member 61 and the second detection member 62 may both be distance sensors. Specifically, when the first detection member 61 detects that the distance between the first detection member 61 and the screen of the mobile terminal 100 is less than the preset distance, a detection signal is generated, and the controller controls the second speaker 5 to work. When the second detection member 62 detects that the distance between the first detection member 61 and the back of the mobile terminal 100 is less than the preset distance, a detection signal is generated, and the controller controls the first speaker 4 to work. Further, the preset distance may be 2 mm to 10 mm. Of course, in other implementations, the preset distance may be 1 mm or 0 mm.

[0079] To facilitate the design, processing and production of the speaker, in this embodiment, optionally, the housing 1 includes a first housing 11 and a second housing 12, which are snap-fitted and connected to form a mounting cavity between the first housing 11 and the second housing 12, and the first speaker 4 and the second speaker 5 are both located in the mounting cavity. This arrangement can protect the first speaker 4 and the second speaker 5 from external impact. Optionally, the first housing 11 and the second housing 12 can be connected by screwing, clamping or bonding.

[0080] Optionally, one of the first speaker 4 and the second speaker 5 is fixed to the first housing 11, and the other is fixed to the second housing 12, the first housing 11 is provided with a first volume hole 111, and the second housing 12 is provided with a second volume hole 121. Specifically, the relative positions of the first speaker 4 and the second speaker 5 can be set according to the relative positions of the first housing 11 and the second housing 12. Exemplarily, the first housing 11 can fit the screen of the mobile terminal 100, and in this embodiment, the second speaker 5 is fixed to the second housing 11. This setting makes it easier for the sound of the fixed speaker to spread, and since the connection line of the speaker is set on the back, the above setting is conducive to the layout of the line.

[0081] Regarding the number of speakers, in this embodiment, preferably, at least two first speakers 4 are provided, and at least two second speakers 5 are provided. The above number setting can increase the volume of the external speaker on the one hand; on the other hand, when one of the speakers on the same side is damaged, it can be replaced by other speakers to avoid delaying work.

[0082] Optionally, the thickness of the first speaker 4 is the same as the thickness of the second speaker 5, the back of the first speaker 4 is coplanar with the front of the second speaker 5, and the front of the first speaker 4 is coplanar with the back of the second speaker 5. The above thickness setting can make the most reasonable use of the internal space of the housing 1. Of course, in order to obtain different use effects or adapt to different work requirements, the power of the second speaker 5 can be selected to be greater than that of the first speaker 4. In this case, the thickness of the second speaker 5 can be greater than that of the first speaker 4.

[0083] For ease of installation, in this embodiment, optionally, the first speakers 4 and the second speakers 5 are the same in number and arranged in a clockwise staggered manner. This arrangement helps to achieve an even distribution of gravity, making the entire mobile terminal conference speaker feel better and helping to improve the stability of placing it on the desktop.

[0084] In this embodiment, optionally, the first detection member 61 and the second detection member 62 are both located in the installation cavity. The above-mentioned position setting can protect the first detection member 61 and the second detection member 62 from external impact, which helps to improve the service life of the first detection member 61 and the second detection member 62.

[0085] Regarding the detection method, specifically, the first shell 11 is provided with a first detection hole 112, the first detection member 61 is fixed to the first shell 11, and the first detection member 61 detects the distance between the screen of the mobile terminal 100 through the first detection hole 112, and the second shell 12 is provided with a second detection hole 122, the second detection member 62 is fixed to the second shell 12, and the second detection member 62 detects the distance between the back of the mobile terminal 100 through the second detection hole 122. The setting of the first detection hole 112 and the second detection hole 122 enables the installation cavity to communicate with the outside world, thereby realizing the transmission of the detection signal. Furthermore, two protective covers are respectively covered on the first detection hole 112 and the second detection hole 122. Among them, the material of the protective cover is glass.

[0086] In another embodiment, the first shell 11 and the second shell 12 can be made of transparent material. In this case, the first detection hole 112 and the second detection hole 122 may not be set, and the internal structure can still be observed. When the first detection member 61 and the second detection member 62 are optical sensors, the position status of the shell can be quickly detected.

[0087] Considering that the microphone of the mobile terminal 100 is difficult to clearly receive the voices of participants from different directions during a meeting, the mobile terminal conference speaker further includes a microphone assembly 7, which is disposed on the housing 1 and configured to receive the voices of participants.

[0088] Specifically, referring to the first speaker 4 and the second speaker 5, the microphone assembly 7 includes a first microphone 71 and a second microphone 72, and the first microphone 71 and the second microphone 72 are respectively located on the front and back of the shell 1. When the shell 1 is located in the first position, the second microphone 72 works, and when the shell 1 is located in the second position, the first microphone 71 works, and when the shell 1 is located in the third position between the first position and the second position, the first microphone 71 and the second microphone 72 work simultaneously. The setting of the two microphones can realize the collection of the voices of the participants from all directions. Among them, the two microphones are both arranged in the installation cavity, the first shell 11 is provided with a front sound hole 113, and the first microphone 71 receives the user's voice through the front sound hole 113, and the second shell 12 is provided with a back sound hole 123, and the second microphone 72 receives the user's voice through the back sound hole 123.

[0089] To protect the screen of the mobile terminal 100 from being scratched, in this embodiment, preferably, the housing 1 includes a front buffer 114, and the front buffer 114 is configured to contact the screen of the mobile terminal 100. The front buffer 114 can be made of rubber or silicone.

[0090] Optionally, the front of the housing 1 is provided with a front support portion, and the front buffer 114 is provided on the front support portion. The provision of the front support portion helps to expand the distance between the housing 1 and the screen of the mobile terminal 100. On the one hand, the thickness of the front buffer 114 can be as thin as possible under the premise that the front buffer 114 can play a buffering role, so as to avoid the entire housing 1 from being attached to the screen of the mobile terminal 100. On the other hand, the working mode of the mobile terminal conference speaker can be as follows: when the housing 1 is in any position, the two speakers work at the same time. Or in another embodiment, when the housing 1 is in the first position, the first speaker 4 works and the second speaker 5 works at the same time; when the housing 1 is in the second position, the first speaker 4 works. In this embodiment, the provision of the front support portion can make a gap between most of the front of the housing 1 and the screen of the mobile terminal 100 when the front buffer is attached to the screen of the mobile terminal 100, and the sound of the first speaker 4 can be transmitted through the gap. Optionally, the distance that the front support portion protrudes from the front of the shell 1 can be 2 mm-5 mm, that is, when the front buffer 114 and the screen of the mobile terminal 100 are in contact, the distance between the position where the first volume hole 111 is set on the first shell 11 and the screen of the mobile terminal 100 is 2 mm-5 mm.

[0091] To protect the back of the mobile terminal 100 from being scratched, the housing 1 optionally includes a back buffer 124, and the back buffer 124 is configured to contact the back of the mobile terminal 100. The back buffer 124 can be made of rubber or silicone.

[0092] Furthermore, a back support portion is convexly provided on the back side of the shell 1, and a back buffer 124 is provided on the back support portion. On the one hand, the back buffer 124 can play a buffering role, and the thickness can be as thin as possible to avoid the entire shell 1 from sticking to the back of the mobile terminal 100. On the other hand, with the presence of the above-mentioned back support portion, the working mode of the mobile terminal conference speaker can be as follows: when the shell 1 is in any position, the two speakers work at the same time. Or in another embodiment, when the shell 1 is in the first position, the second speaker 5 works; when the shell 1 is in the second position, the first speaker 4 and the second speaker 5 work at the same time. The height setting of the back support portion can refer to the front support portion.

[0093] In one embodiment, a front support portion is convexly provided on the front side of the shell 1, and a back support portion is convexly provided on the back side of the shell 1, which can protect the screen of the mobile terminal 100 from being scratched, and can also protect the back side of the mobile terminal 100 from being scratched.

[0094] Of course, in the embodiment with a back support portion and a front support portion, the mobile terminal conference speaker can work in the following manner: when the shell 1 is in any position, the two speakers work at the same time, or when the shell 1 is in the first position, the first speaker 4 works; when the shell 1 is in the second position, the second speaker 5 works.

[0095] In the embodiment with the back support part and the front support part, the working mode of the first microphone 71 and the second microphone 72 can refer to the working mode of the first speaker 4 and the second speaker 5, and is not limited to the specific working mode. Exemplarily, when the housing 1 is in the first position, the first microphone 71 works, and when the housing 1 is in the second position, the second microphone 72 works. In another implementation of this embodiment, when the housing 1 is in any position, the first microphone 71 and the second microphone 72 work simultaneously.

[0096] Regarding the flip assembly 2, in this embodiment, optionally, the flip assembly 2 includes a first flip member 21 and a second flip member 22, the first flip member 21 and the second flip member 22 are rotationally connected, the housing 1 and the second flip member 22 are rotationally connected, and the connecting member 3 is provided on the first flip member 21. The provision of the two flip members can realize the conversion of the housing 1 between the first position and the second position, and is more comfortable to use and looks more technological.

[0097] In this embodiment, optionally, the shell 1 is provided with a shell connection portion 13, one end of the second flip member 22 is provided with a second avoidance portion 222, the shell connection portion 13 is located in the second avoidance portion 222, and the two sides of the shell connection portion 13 are respectively rotatably connected to the two sides of the second avoidance portion 222. With the arrangement of the above structure, it is helpful to reduce the overall size of the shell 1 and the second flip member 22.

[0098] In another embodiment, the second end of the second flip member 22 is provided with a second connection portion 223; one end of the first flip member 21 is provided with a first avoidance portion 212, the second connection portion 223 is located in the first avoidance portion 212, and the two sides of the second connection portion 223 are respectively rotatably connected to the two sides of the first avoidance portion 212. With the above-mentioned structure, it is helpful to reduce the overall size of the second flip member 22 and the first flip member 21.

[0099] In the third embodiment, the housing 1 is provided with a shell connecting portion 13, one end of the second flip member 22 is provided with a second avoiding portion 222, the shell connecting portion 13 is located in the second avoiding portion 222, the two sides of the shell connecting portion 13 are respectively rotatably connected to the two sides of the second avoiding portion 222, and the other end of the second flip member 22 is provided with a second connecting portion 223; one end of the first flip member 21 is provided with a first avoiding portion 212, the second connecting portion 223 is located in the first avoiding portion 212, and the two sides of the second connecting portion 223 are respectively rotatably connected to the two sides of the first avoiding portion 212. With the above-mentioned structure, it is helpful to reduce the overall size of the flip assembly 2.

[0100] In order to further reduce the size of the flip assembly 2, the present embodiment provides the following three implementation modes, wherein, in one implementation mode, an end of the housing 1 close to the second flip member 22 and an end of the shell connecting portion 13 close to the second avoidance portion 222 are both provided with arc surfaces. In the second implementation mode, both ends of the second flip member 22, the bottom of the second avoidance portion 222 and an end of the second connecting portion 223 close to the first flip member 21 are both provided with arc surfaces. In the third implementation mode, an end of the first flip member 21 close to the second flip member 22 is provided with an arc surface. In other words, the adjacent ends of the housing 1 and the second flip member 22 are both semi-cylindrical structures, and the adjacent ends of the second flip member 22 and the first flip member 21 are both semi-cylindrical structures. The provision of the above arc surfaces enables the gap between the housing 1 and the second flip member 22 and the gap between the second flip member 22 and the first flip member 21 to be reduced as much as possible under the premise that the flip assembly 2 can be bent, thereby further reducing the size of the flip assembly 2. It should be noted that the above three implementation modes can be implemented separately or any two or three of them can be implemented simultaneously, and as long as the implementation mode with the arc surface is present, it is beneficial to reduce the size of the flip assembly 2. Furthermore, each arc surface gradually shrinks from the middle of the conference speaker to both sides, so that the gap between the shell 1 and the second flip piece 22 and the gap between the second flip piece 22 and the first flip piece 21 gradually expand from the middle of the conference speaker to both sides, avoiding interference between the shell 1 and the second flip piece 22 and between the second flip piece 22 and the first flip piece 21 during the bending process of the flip assembly 2.

[0101] The flip assembly 2 also includes a damping assembly 23. Regarding the setting of the damping assembly 23, in another embodiment, the damping assembly 23 is arranged between the first flip member 21 and the second flip member 22, and is configured to stop the first flip member 21 in any direction relative to the second flip member 22. The setting of the damping assembly 23 can achieve the fixation of the relative position of the first flip member 21 relative to the second flip member 22, thereby helping to fix the relative position of the mobile terminal 100 and the mobile terminal conference speaker; in addition, it can enhance the feel of use and improve the user experience.

[0102] In another embodiment, the damping component 23 is disposed between the second flip member 22 and the housing 1, and the damping component 23 is configured to stop the second flip member 22 in any direction relative to the housing 1. The provision of the damping component 23 can achieve the fixation of the relative position of the second flip member 22 and the housing 1, thereby helping to fix the relative position of the mobile terminal 100 and the mobile terminal conference speaker; in addition, it can enhance the feel of use and improve the user experience.

[0103] In the third embodiment, a damping assembly 23 is provided between the first flip member 21 and the second flip member 22 and between the second flip member 22 and the housing 1. The above arrangement enables the mobile terminal conference speaker to be stopped at any angle relative to the mobile terminal 100.

[0104] Regarding the relationship of the rotation connection, in this embodiment, specifically, the flip assembly 2 also includes a rotation shaft 221 and a rotation hole, one of which is provided on the first flip member 21 and the other is provided on the second flip member 22, and the rotation shaft 221 is passed through the rotation hole. In other embodiments, the relative rotation of the first flip member 21 and the second flip member 22 can also be achieved in the form of a hinge.

[0105] Regarding the structure of the damping assembly 23, in this embodiment, optionally, the rotating shaft 221 is provided on the second flip member 22, the rotating hole is provided on the first flip member 21, the first flip member 21 is provided with a friction portion 211, and the damping assembly 23 includes a damping member 231, the damping member 231 is arranged around a portion of the rotating shaft 221, and can abut against the friction portion 211. Specifically, the damping member 231 is a rubber ring, and the rubber ring is sleeved on the rotating shaft 221. The above arrangement plays a damping role on the one hand, and can also play a sealing role on the other hand to prevent dust from entering the first flip member 21.

[0106] Optionally, the surface roughness of the friction part 211 is greater than the surface roughness of other parts of the first flip member 21. This arrangement makes the friction between the damping member 231 and the friction part 211 larger, thereby helping to improve the locking effect of the relative position between the first flip member 21 and the second flip member 22.

[0107] Regarding the preparation of the friction part 211 , in this embodiment, optionally, the friction part 211 is prepared by a texturing process. Of course, in other embodiments, the friction plate with a surface treated by a texturing process can be fixed on the first flip member 21 .

[0108] Regarding the structure of the damping assembly 23, in another embodiment, optionally, the rotating shaft 221 is provided on the second flip member 22, the rotating hole is provided on the first flip member 21, the damping assembly 23 includes a damping ring 232 and a damping plate 233, the damping ring 232 is axially uniformly protruded with a plurality of elastic protrusions, a plurality of grooves 23221 are formed between the plurality of elastic protrusions, a clamping portion 2331 is protruded on the damping plate 233, the damping ring 232 is fixed on the rotating shaft 221, the damping plate 233 is fixed on the first flip member 21, and during the rotation process of the second flip member 22 relative to the first flip member 21, the clamping portion 2331 is selectively clamped in one of the grooves 23221. The arrangement of the groove 23221 and the clamping portion 2331 makes the rotation process between the first flip member 21 and the second flip member 22 appear more obviously, thereby improving the operating feel. Moreover, since the clamping portion 2331 is clamped in the groove 23221, the first flip member 21 and the second flip member 22 are fixed more firmly, and the elastic force of the elastic protrusion needs to be overcome in order to change the angle between the first flip member 21 and the second flip member 22.

[0109] Specifically, the damping ring 232 includes a stopper 2321 and an elastic ring 2322. The cross section of the elastic ring 2322 is wavy. The stopper 2321 is arranged at one end of the elastic ring 2322. The stopper 2321 abuts against the end of the rotating shaft 221. The above-mentioned structure makes the design and manufacture of the damping ring 232 simpler and easier to implement, and reduces the cost. On the other hand, the setting of the stopper 2321 helps to determine the installation position of the damping ring 232, and improves the installation efficiency.

[0110] Preferably, the stopper sheet 2321 and the elastic ring 2322 are integrally formed. Specifically, the damping ring 232 is formed by stamping a sheet member or by bending after stamping. This process reduces the cost of the damping ring 232 as much as possible and makes the connection between the stopper sheet 2321 and the elastic ring 2322 more secure.

[0111] In this embodiment, preferably, the stopper sheet 2321 is provided with a positioning hole 23211, and a positioning member is provided at the end of the rotating shaft 221, and the positioning member is passed through the positioning hole 23211. In this arrangement, the positioning hole 23211 and the positioning member, on the one hand, improve the installation accuracy and efficiency; on the other hand, when the first flip member 21 and the second flip member 22 rotate relative to each other, the damping ring 232 and the rotating shaft 221 can be prevented from rotating relative to each other, thereby improving the positioning accuracy between the damping ring 232 and the damping sheet 233, and further facilitating the realization of the positioning accuracy between the first flip member 21 and the second flip member 22.

[0112] Optionally, the damping ring 232 is bonded or welded to the rotating shaft 221. In addition, the damping sheet 233 is bonded or welded to the first flip member 21. The welding can be achieved by laser welding or ultrasonic welding. When the positioning member is made of plastic, it can be melted and fixed to the stopper sheet 2321.

[0113] Preferably, two damping sheets 233 are provided, and the two damping sheets 233 are arranged in the circumferential direction of the damping ring 232 and symmetrically about the center of the damping ring 232. The provision of the two damping sheets 233 enables the two grooves 23221 of the damping ring 232 to be simultaneously engaged with the engaging portions 2331 on the two damping sheets 233, further improving the damping effect.

[0114] Optionally, the damping ring 232 and the damping sheet 233 may be made of beryllium bronze or other metal materials with elasticity. The clamping portion 2331 is a protruding structure formed on the other side after stamping one side of the damping sheet 233 .

[0115] In another embodiment, the damping ring 232 and the damping plate 233 and the damping member 231 and the friction portion 211 may coexist to further increase the damping coefficient between the first flip member 21 and the second flip member 22 .

[0116] Since a cable 200 is provided between the control unit 300 and the connecting member 3, the control unit 300 is on the second housing 11, and the connecting member 3 is installed on the first flip member 21, the cable 200 needs to pass through the second flip member 22. In order to prevent the cable 200 from being worn when the first flip member 21 and the second flip member 22 rotate relative to each other, in this embodiment, preferably, a connecting hole 2211 is provided axially of the first rotating shaft 221, and the cable 200 connected to the connecting member 3 is partially located in the first flip member 21, and the cable 200 passes through the connecting hole 2211 and is partially located in the second flip member 22.

[0117] Preferably, the connector 3 includes a USB-C interface or a lighting interface. This configuration enables the connector 3 and the mobile terminal 100 to be electrically connected after being plugged in, avoiding the need to power the mobile terminal conference speaker separately during use, further streamlining the accessories of the mobile terminal conference speaker, and providing convenience for the use and carrying of the mobile terminal conference speaker.

[0118] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
