Description

Technical Field

[0001] The present invention belongs to the technical field of wireless microphones and wired microphones, and in particular, to a split multi-directional detachable microphone transmitter. Background Art

[0002] In recent years, lapel microphones have become rapidly popular and have become one of the commonly used equipment in scenarios such as short video shooting, online live streaming, and daily Vlog recording. Currently, one of the problems with lapel microphones is reflected in the limitation of sound collection: the microphone head is usually fixedly arranged, making the direction of the microphone head fixed and unchanged. This fixed sound collection direction design limits the application scenarios of the microphone. For example, in an interview scenario, the interviewee may move or change the direction of speaking, and it is difficult for a fixed-direction microphone to effectively capture all sounds, resulting in poor recording effects. Therefore, it cannot meet the dynamically changing recording requirements.

[0003] In addition, with the development of recording technology, there are increasingly high requirements for the directivity and flexibility of microphones. For example, in application scenarios such as video conferencing and theater performances, a more flexible sound collection environment is required to concentrate on capturing sounds in a specific direction and effectively reduce the interference of other environmental noises. Therefore, the demand for lapel microphones with adjustable microphone head pointing angles is also becoming more urgent. Although there are already some lapel microphones that can change the pointing by adjusting the angle of the microphone head, their adjustable range is limited, the adjustment is difficult, and the operation is inconvenient. Moreover, due to the fixed structure of the microphone head, there are still certain difficulties in flexibly adjusting the sound collection direction. These existing solutions cannot effectively solve the problems of single sound collection direction and insufficient flexibility of traditional lapel microphones. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, a split multi-directional detachable microphone transmitter is proposed, which can be adapted to different application scenarios and uses by means of split installation and flexible switching of different microphone heads.

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] Provide a split multi-directional detachable microphone transmitter, as Figures 1 to 6 shown, including a housing 1, a connecting bracket 2 and a microphone 3. An installation cavity is arranged inside the housing, and a PCBA board 4 is arranged in the installation cavity; one end of the connecting bracket 2 is detachably connected to the end of the housing, and the other end is provided with a microphone 3; an FPCB or a wire 5 for electrically connecting the PCBA board 4 and the microphone 3 is arranged inside the connecting bracket 2; the whole of the connecting bracket 2 and the housing 1 forms a U / C / V-shaped clamping structure.

[0030] When in use, the connecting bracket and the microphone can be detached from the housing together, which is convenient for replacing with another specification of microphone, for example, a single-sided directional sound pickup microphone, a horizontal double-directional sound pickup microphone or a wide-angle directional sound pickup microphone, etc., to adapt to different application scenarios. At the same time, the connecting bracket and the housing form a clamping structure in the shape of a U, C or V, which is convenient for clamping use.

[0031] Furthermore, the connecting bracket 2 is in an L shape, a J shape or a C shape, and the side surface of the housing 1 is in an I shape, so that the connecting bracket 2 and the housing 1 form a more streamlined clamping mechanism.

[0032] Furthermore, the connecting bracket 2 includes a first connecting portion 21, an extending portion 23 and a second connecting portion 22, which are arranged in sequence along a linear direction. The first connecting portion 21 is used for detachably connecting with the end of the housing 1, the second connecting portion 22 is used for assembling the microphone 3, and the extending portion 23 is between the first connecting portion 21 and the second connecting portion 22. An interface exposed to the housing is arranged on the PCBA board 4, and a connector 24 detachably connected with the interface is arranged on the first connecting portion 21.

[0033] Among them, the first connecting portion, the extending portion and the second connecting portion are thermoset by a soft rubber material, but not limited thereto. Structurally, the interfaces of the two can be detachably connected by plugging and unplugging; at the same time, in terms of electrical functions, both the interfaces and the connectors are set as common standard parts for electrically connecting the PCBA board and the microphone. When replacing different connecting brackets, the new microphone can be quickly matched with the PCBA board.

[0034] Further, a counterbore opening 11 is provided at the top of the housing; the interface includes pin jacks, and the pin jacks are exposed at the counterbore opening 11; the connector includes a connecting seat and connecting pins 26 provided on the connecting seat and arranged downward; when the connector 24 is detachably connected to the interface, the connecting seat 25 is snap-fitted with the counterbore opening 11, and the connecting pins 26 are inserted into the pin jacks and electrically connected to the PCBA board 4.

[0035] Among them, the number of pin jacks corresponds to the number of connecting pins. The connecting pins are made of copper posts, such as 3PIN, 5PIN, etc., but not limited thereto. The shape of the counterbore opening matches that of the connecting seat, facilitating the snap-fitting of the two, so that the connecting bracket is not easily loosened. In this implementation, the connecting bracket is snap-fitted and fixed downward from the top of the housing, making the connecting bracket and the side of the housing form a downward U shape, which can be applied to common clamping scenarios. It can be understood that the position of the counterbore opening and the insertion direction of the connecting pins can also be flexibly set, not limited thereto.

[0036] Further, a shrapnel structure 6 is embedded in the connecting bracket, and the shrapnel structure 6 penetrates through the first connecting portion 21, the extending portion 23, and the second connecting portion 22. Specifically, the shrapnel structure 6 is integrated into the first connecting portion 21, the extending portion 23, and the second connecting portion 22 by in-mold injection or in-mold thermosetting, but not limited thereto.

[0037] In one implementation, the shrapnel structure 6 is designed as an L / J / C-shaped arc plate structure to adapt to the shape of the connecting bracket 2; an FPCB is attached to the shrapnel structure 6, and both ends of the FPCB are electrically connected to the connecting pins 26 and the microphone 3 respectively.

[0038] In another implementation, the shrapnel structure 6 is designed as an L / J / C-shaped sleeve structure, so that the FPCB or the wire can be placed inside the shrapnel structure 6, and both ends of the FPCB and both ends of the wire are electrically connected to the connecting pins 26 and the microphone 3 respectively.

[0039] The shrapnel structure can support the connecting bracket to generate a certain deformation and form a certain clamping angle with the housing to achieve the clamping function.

[0040] Further, a coating layer is wrapped outside the shrapnel structure, and the coating layer is made of an elastic material, such as soft rubber. On the one hand, the soft rubber can generate adaptive deformation to cooperate with the shrapnel structure to achieve elastic deformation and smoothly perform the clamping action; on the other hand, the soft rubber material can effectively buffer the structural stress generated by the deformation, effectively delay the structural fatigue, and improve the service life of the connecting bracket.

[0041] Further, the microphone includes a mounting shell 31 and a microphone element 32 arranged inside the mounting shell; a perforation is provided on the mounting shell, and one end of the FPCB or one end of the wire is electrically connected to the microphone element through the perforation.

[0042] Among them, the shape of the installation shell can be flexible and diverse. For example, the installation shells for unidirectional pointing microphone heads and horizontally bidirectional pointing microphone heads are cylindrical. The sound pickup holes of the unidirectional pointing microphone heads are arranged on one side of the cylindrical shape, and the sound pickup holes of the horizontally bidirectional pointing microphone heads are arranged on the two end faces of the cylindrical shape. The installation shell for the wide-angle pointing microphone head is an oblate body, and its sound pickup holes are arranged on the front face of the oblate body. The perforations are opened on the inner side of the installation shell so that the FPCB or wires are not exposed outside.

[0043] Furthermore, a key switch is provided on the PCBA board, and a key structure 7 corresponding to the position of the key switch is provided on the housing. The key switch is used to control functions such as turning on or off the transmitter. The key structure 7 includes a hole on the housing corresponding to the key switch and a key covering the hole. The user triggers the key switch through the key structure 7. The positions of the key switch and the key structure can be flexibly set. For example, in one implementation, the housing includes a front cover and a rear cover that are joined together. Mounting holes are provided on the sides of both the front cover and the rear cover. When the front cover and the rear cover are joined, the mounting holes form the said hole.

[0044] Furthermore, a rechargeable battery 8 electrically connected to the PCBA board is provided inside the housing, such as a built-in lithium battery, for supplying power to the transmitter. The battery is charged through a Type-C or other charging interface. Preferably, the battery is equipped with an overvoltage protection IC to ensure charging safety.

[0045] Furthermore, an LED indicator light 9 electrically connected to the PCBA board is provided on the microphone head. The LED indicator light 9 is used to feedback information such as the microphone recording state, power state, and wireless connection state. Preferably, a light guide member 10 corresponding to the LED indicator light is provided on the installation shell of the microphone head to facilitate the user to observe the usage state.

[0046] It can be understood that conventional components including a wireless module, a MEMS microphone, and an audio processing chip are also built inside the housing. Among them, the wireless module converts the sound signal into a wireless signal and then transmits it through the antenna. This wireless signal can be transmitted through the 2.4G wireless frequency band to achieve wireless connection with the receiver. The MEMS microphone is used to collect sound and convert the captured sound into an electrical signal. The audio processing chip, such as a DSP chip, is used to process the audio signal collected by the microphone, including functions such as noise reduction, reverberation beautification, intelligent noise reduction, and audio processing.

[0047] The above is an elaboration of the split multi-directional detachable microphone transmitter of the present invention to help understand the present invention; however, the implementation manners of the present invention are not limited by the above embodiments. Any changes, modifications, substitutions, combinations, and simplifications made without departing from the principle of the present invention shall be equivalent replacement methods and are all included in the protection scope of the present invention.
