The utility model provides a microphone assembly. Referring to fig. 1, fig. 1 is a schematic structural diagram of a microphone assembly according to an embodiment of the utility model. The microphone assembly 100 may include a microphone body 10, a case 20, and a vibration plate 30. The microphone body 10 may convert sound signals into electrical signals.

The housing 20 includes an inner surface 21 and an outer surface 22 disposed opposite to each other, and the microphone body 10 is mounted on the inner surface 21 side of the housing 20. The main sound inlet channel 23 and the auxiliary sound inlet channel 24 penetrating through the outer surface 22 are formed in the shell 20, the main sound inlet channel 23 and the auxiliary sound inlet channel 24 are communicated with the microphone body 10, and air flow caused by sound wave vibration can be conducted to the microphone body 10 through the main sound inlet channel 23 or conducted to the microphone body 10 through the auxiliary sound inlet channel 24. The arrangement of the plurality of sound inlet channels provides multiple paths for sound conduction and provides multiple guarantees for normal use of the equipment.

Further, the outer surface 22 is provided with a vibration plate 30 at the position of the secondary sound inlet channel 24 to prevent foreign objects (such as water, slurry or dust) from blocking the secondary sound inlet channel 24, and the vibration plate 30 can be forced to vibrate to transmit the received sound to the microphone body 10 through the secondary sound inlet channel 24. When the voice pick-up area on the outer surface of the electronic equipment is plugged by an external object, the vibration of the vibration plate 30 can be forced to vibrate only by removing the attachment on the outer surface of the vibration plate 30 through the sound wave vibration of sound, and the vibration of the vibration plate 30 is conducted to the microphone body 10 through the air in the auxiliary sound inlet channel 24, so that smooth voice pick-up is realized.

According to the microphone assembly 100 provided by the utility model, the main sound inlet channel 23 and the auxiliary sound inlet channel 24 are formed in the shell 20, the vibration piece 30 is arranged on one side of the outer surface 22 of the auxiliary sound inlet channel 24, so that the auxiliary sound inlet channel 24 can be prevented from being blocked by foreign objects, when the main sound inlet channel 23 is blocked by foreign objects, the vibration piece 30 can be forced to vibrate to transmit received sound to the microphone body 10 through the auxiliary sound inlet channel 24, emergency voice pickup is realized, and the problem that communication cannot be realized after the sound inlet channel of the microphone is blocked by foreign objects can be avoided.

In one embodiment, the thickness of the vibration plate 30 may be 0.04-0.08 mm. Specifically, the thickness value of the vibration plate 30 may be 0.04, 0.05, 0.06, 0.07, 0.08, or the like. When the thickness of the vibration plate 30 is within the above range, not only can the forced vibration be well performed to pick up the sound, but also the vibration plate can be prevented from being broken, and the foreign object can be effectively prevented from blocking the sub-sound inlet channel 24.

The material of the vibration plate 30 may be one of metal, PC (polycarbonate), PVC (polyvinyl chloride), PET (polyethylene terephthalate), or bio-composite material. PC has high impact strength, good dimensional stability and small creep; PVC has good chemical stability and good tensile, bending, compressive and impact resistance; PET has excellent physical and mechanical properties in a wider temperature range, and has good creep resistance, fatigue resistance, friction resistance and dimensional stability, and the materials can effectively prevent the auxiliary sound inlet channel 24 from being punctured by foreign objects to be blocked.

In an embodiment, the vibration plate 30 is a label of the electronic device, that is, the label of the electronic device and the vibration plate 30 are combined into one, and the label of the electronic device is also used as the vibration plate 30, which is beneficial to simplifying the setting of the external surface of the electronic device.

In an embodiment, the outer surface 22 is provided with a vibration groove 221, the vibration groove 221 is disposed corresponding to the vibration piece 30, and the vibration groove 221 provides a vibration space for the vibration piece 30, so that the vibration piece 30 can force vibration and transmit received sound. Specifically, the depth of the vibration groove 221 is greater than the maximum amplitude of the vibration plate 30, and the vibration of the vibration plate 30 is not limited by the outer surface 22, thereby ensuring the accuracy of the transmission sound of the forced vibration of the vibration plate 30. The length of the vibration groove 221 may be 6 to 20mm, the width may be 3 to 10mm, the depth may be 0.2 to 0.3mm, and the specific size of the vibration groove 221 may be adjusted according to the size of the tag. The vibration grooves 221 provide the vibration plate 30 with a larger vibration area to improve the acoustic performance of the sub-sound inlet passage 24. When the depth of the vibration groove 221 is within the above range, the vibration space of the vibration plate 30 can be secured, and breakage or falling-off caused by excessive deformation when the vibration plate 30 is pressed can be avoided.

In an embodiment, the main sound inlet channel 23 may include a first channel 231, a second channel 232, and a third channel 233 that are sequentially communicated. Wherein the first channel 231 penetrates the outer surface 22, the third channel 233 is communicated with the microphone body 10, and the extending direction of the second channel 232 is different from the extending direction of the first channel 231. Since the extending direction of the second channel 232 is different from that of the first channel 231, that is, the second channel 232 and the first channel 231 are bent, the foreign objects can be prevented from continuously entering the second channel 232, so that the foreign objects entering the main sound inlet channel 23 are generally accumulated in the first channel 231, and the foreign objects can be cleaned only by cleaning the first channel 231, thereby reducing the difficulty of cleaning and maintenance.

Further, in an embodiment, the extending direction of the first channel 231 is perpendicular to the outer surface 22 of the housing 20, and a cone-shaped accommodating space 234 is provided at an end of the first channel 231 away from the outer surface 22. Since the end section of the cone-shaped receiving space 234 is retracted, the space where the water drops enter the smaller section has surface tension, and the water entering the first passage 231 can be adsorbed in the cone-shaped receiving space 234, thereby holding the foreign objects and preventing the foreign objects from continuing to enter the second passage 232 too deeply.

In an embodiment, the communication position between the second channel 232 and the first channel 231 is located outside the cone-shaped accommodating space 234, so that the foreign objects entering the first channel 231 are collected in the cone-shaped accommodating space 234 and cannot enter the second channel 232.

In an embodiment, the secondary sound inlet channel 24 includes a fourth channel 241 and a fifth channel 242 that are sequentially communicated, the fourth channel 241 penetrates the outer surface 22, and the extending direction of the fourth channel 241 is different from the extending direction of the fifth channel 242. The fifth channel 242 may be directly connected to the microphone body 10, i.e. the secondary sound inlet channel 24 is independent from the primary sound inlet channel 23. The fifth channel 242 may be communicated with the third channel 233, and the auxiliary sound inlet channel 24 is communicated with the microphone body 10 through the third channel 233, that is, the auxiliary sound inlet channel 24 and the main sound inlet channel 23 share part of the sound inlet channel, so that occupation of the sound inlet channel to the housing 20 can be reduced, and arrangement of other components of the electronic device is facilitated.
