Description

Technical Field

[0001] This utility model belongs to the field of loudspeaker technology, specifically relating to a connector for loudspeakers and a loudspeaker. Background Technology

[0002] In scenarios such as meetings, training sessions, and small presentations, all-in-one conference amplifiers have become important devices for ensuring clear sound transmission and improving information transmission efficiency due to their advantages such as high integration, portability, and ease of use. Currently, there are many types of such products on the market, which can meet the basic amplification needs of different users in different occasions, and the market application scope continues to expand.

[0003] Currently, most loudspeakers on the market are prone to feedback when increasing volume gain to boost sound output intensity. This severely interferes with meetings, lectures, and other similar events, compromising the clarity and stability of sound propagation. During a user's speech, the entire loudspeaker enclosure vibrates due to sound output. This vibration is conducted through the metal microphone shaft connected to the enclosure and ultimately reaches the electret microphone head mounted on it. The vibration is absorbed by the electret microphone head, creating a positive feedback loop that triggers feedback. Utility Model Content

[0004] To address the shortcomings of the prior art, this utility model provides a feedback improvement structure and amplifier that can suppress feedback-induced feedback during amplifier use.

[0005] The technical effects to be achieved by this utility model are realized through the following aspects: In a first aspect, this utility model provides a connector for a loudspeaker, comprising: The connector body has through holes extending through both ends along the axial direction. One end of the connector body has a positioning protrusion for connecting with the microphone rod, and the other end of the connector body is for connecting with the cup head. A soft buffer structure is provided between the two ends of the connector body along the circumferential direction. The soft buffer structure includes multiple annular damping grooves, with adjacent annular damping grooves spaced apart along the axial direction of the connector body, for dispersing and buffering the transmitted vibration energy.

[0006] In some implementations, an annular boss is formed between two adjacent annular damping grooves in the plurality of annular damping grooves.

[0007] In some implementations, the sinking depth of the annular damping groove is L1, the width of the annular damping groove is L2, and L2 is 1 / 3 to 2 / 3 of L1.

[0008] In some implementations, the diameter of the via is 2mm to 4mm.

[0009] In some implementations, the positioning protrusion is a stepped structure, comprising a first-level step and a second-level step arranged sequentially along the protrusion direction, wherein the diameter of the first-level step is larger than the diameter of the second-level step, and the end face of the second-level step is chamfered.

[0010] Secondly, this utility model provides a loudspeaker, comprising: The connector, mounting base, microphone assembly, and pickup assembly for the loudspeaker described in any of the above implementations are provided with a speaker on the mounting base, and the pickup assembly is connected to one end of the microphone assembly via the connector for the loudspeaker, and the other end of the microphone assembly is connected to the mounting base.

[0011] In some implementations, the microphone assembly includes a microphone rod and a universal joint, with one end of the microphone rod connected to the mounting base via the universal joint, and the other end of the microphone rod connected to the main body of the connector.

[0012] In some implementations, the pickup assembly includes a microphone and a cup head, with the microphone installed inside the cup head and one end of the cup head fitted onto the connector body.

[0013] In some implementations, the cup head is provided with a head pad and a head sponge, the head sponge is located at one end of the head near the connector body, and the head pad is located at the other end of the head.

[0014] In summary, this utility model has at least the following advantages: This utility model provides a connector for a loudspeaker and a loudspeaker. The connector for the loudspeaker blocks the transmission of vibration. As a connecting structure between the microphone boom and the microphone head, the connector can absorb externally transmitted vibration energy through its own deformation. The positioning protrusion at one end of the connector body serves as a connection support, while the connector has a soft buffer structure, which gives the part between the two ends of the connector a flexible vibration reduction effect. The annular damping groove of the soft buffer structure acts as a local buffer area to reduce the vibration transmission efficiency, further optimize vibration absorption and energy dispersion, so that the pickup element in the microphone head is not affected by external vibration interference, and achieves the effect of suppressing howling feedback.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] Example 1: Please see Figure 1 and Figure 3 The present invention provides a connector 1 for a loudspeaker, comprising: a through hole 14 extending through both ends along the axial direction; a positioning protrusion 13 for connecting to a microphone rod 31 at one end of the connector body 11; a cup head 22 for connecting to the other end of the connector; and a soft buffer structure 12 provided between the two ends of the connector along the circumferential direction; the soft buffer structure 12 includes a plurality of annular damping grooves 121, adjacent annular damping grooves 121 being spaced apart along the axial direction of the connector body 11 to disperse and buffer the transmitted vibration energy.

[0023] Specifically, the connector 1 used for the loudspeaker has a tubular structure. Its connector body 11 has through holes 14 extending through both ends. The through holes 14 are used for wire threading. A soft buffer structure 12 is provided in the circumferential direction of the connector body 11. The soft buffer structure 12 is used to disperse the vibration energy transmitted from the outside. The vibration energy is gradually attenuated by the soft buffer structure 12. Moreover, this structure can make the connector body more flexible, increase the recoverable deformation of the connector body 11, and make it have a spring effect.

[0024] One end of the connector body 11 is connected to the cup head 22 with the microphone head 21, and the other end of the connector body 11 is connected to the microphone rod 31. A positioning protrusion 13 is provided on the end of the connector body 11 used to connect the microphone rod 31, so that it can be inserted and fixed with the mounting end of the microphone rod 31. The positioning protrusion 13 can play a role in bearing force support, and is interference fit with the microphone rod 31, and then fixed with glue.

[0025] The soft buffer structure 12 is composed of multiple annular damping grooves 121 forming a segmented damping barrier. The annular damping grooves 121 are coaxially arranged with the main body 11 of the connector. The multiple annular damping grooves 121 are distributed sequentially along the axial direction at intervals, which increases the deformation adaptability of the main body 11 of the connector. It plays a better role in suppressing low-frequency sounds below 1KHz, such as vibration feedback of 900 Hz-100Hz, and the vibration energy is gradually reduced through multi-segment buffering and damping.

[0026] Understandably, the connector 1 used for the loudspeaker is made of a flexible material in one piece, which can absorb vibration energy through deformation, and the one-piece structure eliminates connection gaps, avoiding the generation of additional vibration or friction.

[0027] It is worth noting that the length of the connector body 11 of the connector 1 used for the loudspeaker can be selected, but is not limited to, 35mm ± 5mm. In some embodiments, the length of the connector body 11 is specifically 35mm. When applied to application scenarios such as conference speeches and teaching lectures, it can effectively reduce the minute vibrations transmitted by the fixed platform, thereby avoiding the vibrations being absorbed by the microphone 21 and producing howling.

[0028] In this embodiment, the connector 1 for the loudspeaker adopts a flexible material integrated structure. The soft buffer structure 12 increases the flexibility of the connector body, giving it recoverable deformation. The multiple annular damping grooves 121 within the soft buffer structure 12 disperse and dissipate vibration transmission, preventing vibration from the tabletop from affecting the sound reception. A positioning protrusion 13 is provided at the end of the connector body 11 that is fixed to the microphone rod 31. An interference fit is used to achieve a tight fixation, further filling the connection gap and preventing loosening of the connection when rotating the adjustment component, which would affect the subsequent sound reception.

[0029] Example 2: This embodiment is a further structural optimization of the connector for a loudspeaker according to this utility model. Please refer to [link / reference]. Figure 1 and 2 .

[0030] In some embodiments, an annular boss 122 is formed between two adjacent annular damping grooves 121 of the plurality of annular damping grooves 121.

[0031] Specifically, an annular boss 122 is formed between two adjacent annular damping grooves 121 for separation. Vibration energy is transmitted from one end of the connector body 11 to the other end, and the energy is dissipated to the annular boss 122 through the annular damping groove 121. The vibration energy is reflected by the annular boss 122, and the reflected energy is superimposed and canceled by the energy of the subsequent incident energy, further weakening the transmission of vibration.

[0032] In some embodiments, the sinking depth of the annular damping groove 121 is L1, and the width of the annular damping groove 121 is L2, where L2 is 1 / 3 to 2 / 3 of L1.

[0033] Specifically, by adjusting the size of the annular damping groove 121, the efficiency of vibration energy absorption is changed to achieve a better effect of suppressing vibration feedback. If the annular damping groove 121 is too wide, the deformation of the main body 11 of the connector will decrease. The sinking depth L1 is greater than the width L2, and L2 is in the range of 1 / 3 to 2 / 3 of L1, so that the flexible buffer structure 12 can maintain sufficient structural strength and also have a certain stability of deformation recovery.

[0034] It is worth noting that in some implementations, the axial length of the connector body 11 is 35mm, there are 3 annular damping grooves 121, the sinking depth of the annular damping grooves 121 is 3mm, and the width of the annular damping grooves 121 is 1.5mm.

[0035] In some embodiments, the diameter of the via 14 is 2mm to 4mm.

[0036] Specifically, the via 14 passes through both ends of the connector body 11, allowing the wire harness to pass through from one end of the via 14 to the other. The diameter of the via 14 is 2mm to 4mm. In some implementations, the diameter of the via 14 is 2mm, and the peripheral thickness of the connector body 11 is 5.5mm.

[0037] In some embodiments, the positioning protrusion 13 has a stepped structure, and the positioning protrusion 13 includes a first-level step 131 and a second-level step 132 arranged sequentially along the protrusion direction. The diameter of the first-level step 131 is larger than the diameter of the second-level step 132, and the end face of the second-level step 132 is provided with a chamfer 133.

[0038] Specifically, a positioning protrusion 13 is provided at one end of the connector body 11 for fixing and cooperating with the desktop fixed end device. The positioning protrusion 13 has a stepped structure, which is divided into a first step 131 and a second step 132 along the protrusion direction. The second step 132 is smaller than the first step 131. The second step 132 extends outward with a chamfer 133 to increase the contact area and the support strength of the connection, and also facilitates the bonding effect of secondary reinforcement with glue.

[0039] The main body 11 of the connector is made of silicone. In some implementations, the silicone hardness is 30 degrees. In a conference scenario, frequent shouting by users causes the platform to vibrate continuously. The low-hardness silicone can continuously weaken the vibration transmission through deformation. Moreover, silicone material ages slowly and can maintain stable elastic deformation capacity, avoiding a decrease in the vibration damping effect of the annular damping groove 121 due to material aging.

[0040] In this embodiment, the connector body 11 is made of silicone with a hardness of 30 degrees. A soft buffer structure 12 consisting of three annular damping grooves 121 is provided on the connector body 11. The annular damping grooves 121 are coaxially arranged with the through hole 14 to disperse vibration transmission. One end of the connector body 11 is provided with a positioning protrusion 13 for connecting and fixing to the desktop fixed end. The positioning protrusion 13 is divided into a first-level step 131 and a second-level step 132, which plays a positioning and limiting role when plugging in. The chamfer 133 is used to increase the contact surface at the connection, making the overall connection more stable.

[0041] Example 3: Please see Figure 3 and Figure 4 and combined Figure 1 The present invention provides a loudspeaker 100, comprising: a connector 1 for the loudspeaker, a mounting base 4, a microphone assembly 3, and a pickup assembly 2. The mounting base 4 is equipped with a loudspeaker. The pickup assembly 2 is connected to one end of the microphone assembly 3 via the connector 1 for the loudspeaker, and the other end of the microphone assembly 3 is connected to the mounting base 4.

[0042] Specifically, the loudspeaker 100 comprises a pickup assembly 2, a microphone boom assembly 3, a connector 1 for the loudspeaker, and a mounting base 4. The mounting base 4 serves as a support for the device and integrates signal processing and amplification functions. This loudspeaker is an integrated receiver / amplifier unit. The mounting base 4 is equipped with a speaker. The pickup assembly 2 is connected and fixed to the connector 1 for the loudspeaker, and is also connected to the microphone boom assembly 3 via the connector 1. The microphone boom assembly 3 is used to adjust the angle and position of the pickup assembly 2, and the other end of the microphone boom assembly 3 is connected and fixed to the mounting base 4.

[0043] In some embodiments, the microphone assembly 3 includes a microphone 31 and a universal bending member 32. One end of the microphone 31 is connected to the mounting base 4 via the universal bending member 32, and the other end of the microphone 31 is connected to the connector body 11.

[0044] Specifically, the microphone rod 31 of the microphone rod assembly 3 is connected to the universal bending member 32, and is inserted into the mounting base 4 through the universal bending member 32 and threadedly connected to the mounting base 4 to achieve arbitrary angle steering adjustment.

[0045] Additionally, the pickup assembly 2 includes a cup head 22 and a microphone head 21 disposed within the cup head 22. The bottom of the cup head 22 is connected and fixed to the connector 1 for the amplifier. The cup head 22 can be fitted onto one end of the connector body 11 and fixed with glue. The positioning protrusion 13 of the connector 1 for the amplifier is connected to the microphone rod 31 of the microphone rod assembly 3. The connecting wire of the microphone head 21 extends from the cup head 22 toward the connector 1 for the amplifier, passes through the through hole 14 on the connector body 11, and passes through the microphone rod assembly 3 to connect with the mounting base 4.

[0046] It is worth noting that when other components are connected to the connector 1 used for the loudspeaker, they are all reinforced with glue to ensure overall stability.

[0047] In some embodiments, the cup head 22 is provided with a plurality of opening slots 222 along the circumferential direction, and a cup head edge mesh 25 is provided inside the cup head 22 to cover the opening slots 222.

[0048] Specifically, the cup head 22 has a cavity for accommodating the microphone 21, and the side wall of the cup head 22 has a plurality of ventilation slots 222 so that the microphone 21 can pick up sound through the slots 222. The cup head edge mesh 25 is provided on the inner wall of the cup head 22 near the slots 222 to block the slots 222, thus providing dust prevention and preliminary filtering functions.

[0049] In some embodiments, the cup head 22 is provided with a head pad 23 and a head sponge 24. The head sponge 24 is disposed at one end of the head 21 near the connector body 11, and the head pad 23 is disposed at the other end of the head 21.

[0050] Specifically, the cup head sponge 24 and the head pad cotton 23 are respectively placed at both ends of the head 21, and the two hold the head 21 tightly and fix it inside the cup head 22. The cup head sponge 24 is placed between the head 21 and the connector body 11, and acts as a buffer medium to further attenuate the residual vibration energy transmitted by the connector body 11. The head pad cotton 23 located on the head 21 reduces the sound wave reflection inside the cup head 22. The cup head sponge 24 and the head pad cotton 23 achieve a low-cost and more stable howling suppression effect.

[0051] In some embodiments, the cup head 22 is provided with a top cover 26 at one end near the sound head pad 23. The top cover 26 is provided with a plurality of vent holes, and a cup head mesh 27 for covering the vent holes is provided inside the top cover 26.

[0052] Specifically, the top of the cup head 22 is provided with a removable top cover 26, which protects the microphone pad 23 inside the cup head 22. The top cover 26 also has multiple ventilation holes, allowing the microphone 21 installed inside the cup head 22 to still pick up sound from the top. In addition, a cup head mesh 27 is provided inside the top cover 26 for protection. The microphone 21 can pick up sound through the top ventilation holes and the circumferentially arranged openings 222, enabling it to fully capture the details of speech. The cup head mesh 27 and the cup head side mesh 25 can prevent dust from entering the cup head 22, avoiding performance degradation of the microphone 21 due to dust accumulation, thus enabling the amplifier 100 to work reliably in complex environments.

[0053] In this embodiment, the amplifier 100 includes a connector 1, a microphone assembly 3, a pickup assembly 2, and a mounting base 4. The connector 1 separates the microphone head 22 from the microphone shaft 31, providing vibration damping and preventing spontaneous vibration of the amplifier 100 or tabletop vibration from being transmitted to the microphone head 21, thus avoiding feedback and howling. Multiple circumferential slots 222 are provided on the side wall of the microphone head 22, and multiple ventilation holes are provided on the top of the microphone head 22, allowing the amplifier 100 to receive sound more clearly from all directions during pickup. Furthermore, a microphone head sponge 24 and a microphone head pad 23 are respectively installed at both ends of the microphone head 21 to further attenuate residual vibration energy.
