[0029] As Figure 1 and Figure 2 As shown, an embodiment of the present utility model provides a headphone case 1 with a recording function. The headphone case 1 includes a first housing 11, a second housing 12, a support frame 13 and a recording component 15. Specifically, the second housing 12 is movably connected to the first housing 11. The support frame 13 is at least used for placing the headphones. The support frame 13 is connected to the second housing 12, and the support frame 13 and the second housing 12 enclose a receiving cavity 14. It can be understood that the first housing 11 and the second housing 12 are movably connected together, and the first housing 11 can rotate relative to the second housing 12 to open or close the headphone case 1. The support frame 13 is disposed between the first housing 11 and the second housing 12 and is connected to the second housing 12. The second housing 12 and the support member 13 enclose a receiving cavity 14, and the receiving cavity 14 is used for placing some components in the headphone case 1. The side of the support frame 13 away from the receiving cavity 14 is used for placing the headphones to store or charge the headphones. After the first housing 11 rotates relative to the second housing 12 and opens, the headphones placed on the support frame 13 can be exposed for picking and placing operations.

[0030] Specifically, the recording component 15 is used to record sounds. There are at least two recording components 15, and they are all located in the accommodation cavity 14. That is to say, the recording component 15 for recording is also provided in the earphone bin 1. The number of the recording components 15 can be set to two or more, and all are arranged in the accommodation cavity 14, so that the earphone bin 1 can have the recording function. The multiple recording components 15 can be arranged symmetrically in the accommodation cavity 14. For example, when there are two recording components 15, one can be arranged on each of the opposite sides of the accommodation cavity 14; when there are four recording components 15, two can be arranged on each of the opposite sides of the accommodation cavity 14, and the two recording components 15 on the same side are arranged at intervals. It is also possible to arrange the four recording components 15 on different sides of the accommodation cavity 14. Of course, it can be understood that the recording components 15 can also be arranged asymmetrically, as long as the sound recording can be satisfied. In this way, the multiple arranged recording components 15 increase the sound recording angle and improve the quality of the recorded sound.

[0031] The earphone bin with a recording function provided by the embodiment of the present utility model includes a first shell, a second shell, a support frame and a recording component. The first shell is movably connected to the second shell. The support frame is at least used for placing the earphone. The support frame is connected to the second shell and encloses an accommodation cavity with the second shell. The recording component is used to record sounds. There are at least two recording components, and they are all located in the accommodation cavity. In this way, by adopting the arrangement of the recording component, the sound can be recorded through the recording component, so that the use function of the earphone bin is expanded. The recording component is arranged in the accommodation cavity formed by the enclosure of the support frame and the second shell, adding components without changing the appearance of the earphone, making the function of the earphone bin more abundant, which is beneficial to improving the user experience. At the same time, setting at least two recording components can further improve the recording effect of the earphone bin and optimize the performance of the product.

[0032] In some embodiments, such as Figure 1 and Figure 2As shown, a clutch seam 111 is formed between the first housing 11 and the second housing 12. The support frame 13 has a sound pickup channel 131 for transmitting sound. One end of the sound pickup channel 131 extends to the recording component 15, and the other end of the sound pickup channel 131 extends to the clutch seam 111. Among them, each recording component 15 is respectively provided with a sound pickup channel 131. It can be understood that when the earphone compartment 1 is in the closed state, the first housing 11 and the second housing 12 are not in complete contact, and there is still a certain gap left. The position of this gap forms the clutch seam 111, and a part of the support frame 13 located at the clutch seam 11 is exposed from the clutch seam 11. By providing the sound pickup channel 131 on the support frame 13, one end of the sound pickup channel 131 communicates with the recording component 15, and the other end communicates to the clutch seam 11. Through the clutch seam 111, it communicates with the outside world. The sound from the outside world can enter the sound pickup channel 131 through the clutch seam 111, and is transmitted to the recording component 15 through the sound pickup channel 131 to record the outside sound. When there are multiple recording components 15, the same number of sound pickup channels 131 are provided on the support frame 13, forming a one-to-one correspondence with the recording components 15, so that each recording component 15 at each position can have a sound pickup channel 131 for sound transmission, improving the effect and quality of sound recording. Moreover, by extending the other end of the sound pickup channel 131 to the clutch seam 111, through the concealment of the clutch seam 111, the sound pickup channel 131 is not directly exposed, and it is not significantly shown on the overall appearance of the earphone compartment 1, without damaging the overall aesthetics of the earphone compartment 1, thus better ensuring the aesthetics of the appearance of the earphone compartment 1, with a clever design.

[0033] In the embodiment of the present utility model, by extending one end of the sound pickup channel to the clutch seam, it can communicate with the external environment, enabling the external sound to be transmitted to the recording component through the sound pickup channel. Thus, even if the recording component is arranged in the accommodation cavity, the recording function can still be successfully completed. And it can better ensure the aesthetics of the overall appearance of the earphone compartment. At the same time, the sound pickup channel and the recording component are arranged in a one-to-one correspondence, improving the recording effect of the recording component, optimizing the product performance, and improving the user experience.

[0034] In some embodiments, such as Figure 1 and Figure 3As shown in the figure, the first housing 11 is movably connected to the first side 121 of the second housing 12. That is to say, the first housing 11 can rotate around the first side 121 of the second housing 12 to control the opening and closing of the earphone compartment 1. The side for opening between the first housing 11 and the second housing 12 is opposite to the first side 121. The sound pickup channels 131 are respectively arranged on the support frame 13 at least at the positions of the second side 122 and the third side 123 of the second housing 12. Among them, the second side 122 and the third side 123 are connected to the opposite ends of the first side 121. It can be understood that the recording components 15 are arranged on the opposite sides of the earphone compartment 1 and are correspondingly arranged with the sound pickup channels arranged at the second side 122 and the third side 123. In this way, the sound pickup channels 131 can be distributed on both sides of the earphone compartment 1. On the one hand, the sound pickup channels 131 arranged on both sides of the earphone compartment 1 can collect sounds from the outside world from different angles, the sound collection is sensitive, and the recording quality of the recording components 15 is also improved; on the other hand, when observing from the front, it is not easy to find the sound pickup channels 131 arranged on both sides, which does not affect the appearance beauty of the earphone compartment 1. It should be noted that the front observation here refers to the perspective perpendicular to the first side 121 or the side for operating when opening the first housing 11.

[0035] In the embodiment of the present utility model, by arranging the sound pickup channels on both sides of the earphone compartment, it is not easy to see the existence of the sound pickup channels on the appearance of the earphone compartment, and the influence of the arrangement of the recording components on the appearance of the earphone compartment is reduced.

[0036] In some embodiments, as Figure 4 shown, the recording component 15 includes a microphone 151 and a connection circuit board 152. The microphone 151 is used to collect sounds. The microphone 151 is electrically connected to the connection circuit board 152. The connection circuit board 152 is at least used to transmit the sound signals converted by the microphone 151. Among them, the connection circuit board 152 is at least connected to the support frame 13. That is to say, the connection circuit board 152 is connected to the support frame 13, the microphone 151 is connected to the connection circuit board 152, and the position of the microphone 151 corresponds to the position of the sound pickup channel 131 on the support frame 13. After receiving the sounds from the outside world in the sound pickup channel 131, the sound signals are transmitted through the connection circuit board 152, so that the recording component 15 can smoothly carry out the recording work.

[0037] It should be noted that the connection circuit board 152 can also be connected to the second housing 12, and the connection circuit board can be stably fixed in the accommodation cavity to meet the working requirements of the recording component 15.

[0038] In the embodiment of the present utility model, by fixing the connection circuit board in the accommodation cavity, the microphone on the connection circuit board corresponds to the position of the sound pickup channel, thereby realizing the recording function of the recording component. In this way, the recording component can be accommodated in the accommodation cavity, optimizing the structure of the earphone case, reducing the product size, and facilitating carrying.

[0039] In some embodiments, as Figure 4 shown, the recording component 15 further includes a noise reduction member 153. The noise reduction member 153 is used to reduce the noise of the sound incoming into the microphone 151 of the recording component 15. Among them, the noise reduction member 153 is arranged in the sound pickup channel 131 and located between the clutch seam 111 and the recording component 15. That is to say, a noise reduction member 153 is further arranged outside the microphone 151. The noise reduction member 153 is located on the path of the sound incoming into the earphone case 1, filters the sound incoming into the microphone 151, and absorbs the noise in the incoming sound, thereby improving the clarity of the sound recording.

[0040] It should be noted that the noise reduction member 153 can be made of mesh cloth and EVA foam, or other materials can be selected, as long as it can meet the noise reduction requirements of the recording component, and no limitation is made here.

[0041] In the embodiment of the present utility model, by arranging a noise reduction member in front of the path where the sound enters the microphone, the noise reduction member filters the sound from the outside world entering the microphone, absorbs the noise, optimizes the quality of the recorded sound, improves the working performance of the recording component, and further improves the quality of the sound recording and the quality of the product.

[0042] In some embodiments, the noise reduction member 153 is attached to the microphone 151 of the recording component 15. It can be understood that the external sound is transmitted to the microphone 151 along the sound pickup channel 131. The noise reduction member 153 needs to be arranged on the sound propagation path to effectively reduce the noise of the sound. The noise reduction member 153 can be directly attached to the microphone 151, or arranged in the sound pickup channel 131, or noise reduction members 153 are arranged on both the microphone 151 and the sound pickup channel 131 to ensure the noise reduction effect of the noise reduction member.

[0043] In the embodiment of the present utility model, by arranging noise reduction members in the microphone and the sound pickup channel, the recording component is effectively noise-reduced without changing the size of the recording component, reducing the volume occupied by the recording component in the accommodation cavity, reducing the overall size of the earphone case, and optimizing the product performance.

[0044] In some embodiments, as Figure 4As shown in the figure, the sound pickup channel 131 includes a first channel 1311 and a second channel 1312 that are connected and communicate with each other. One end of the first channel 1311 extending to one end of the recording component 15 has a first opening 1313, and one end of the second channel 1312 extending to the clutch seam 111 has a second opening 1314. Among them, at least part of the microphone 151 of the recording component 15 is opposite to the first opening 1313. It can be understood that external sound enters the second channel 1312 through the clutch seam 111 from the second opening 1314. The second channel 1312 communicates with the first channel 1311, and the sound enters the first channel 1311 from the second channel 1312 and is transmitted by the first channel 1311 to the first opening 1313, where it is received by the microphone 151 provided at the first opening 1313. At least part of the second opening 1314 communicates with the clutch seam 111. That is to say, part of the second opening 1314 is exposed through the clutch seam 111, and the other part can be covered by the second housing 12. By covering with the second housing 12, it is possible to prevent dust, debris, etc. from entering the sound pickup channel 131 and being blocked, and it is also possible to prevent water from entering the sound pickup channel 131.

[0045] In the embodiment of the present utility model, part of the second opening communicates with the clutch seam, and part of the second opening is covered by the second housing, thereby preventing water or dust from entering the sound pickup channel, protecting the parts while ensuring the normal operation of the recording function, improving the quality of the product, and extending the service life of the product.

[0046] In some embodiments, as Figure 5 shown, the ends where the first channel 1311 and the second channel 1312 are connected and communicate with each other are perpendicular to each other; and / or, the length of the first channel 1311 is 1.8 - 4.2 mm, and the diameter is 0.8 - 2.7 mm; and / or, the length of the second channel 1312 is 2 - 8 mm, and the diameter is 0.8 - 2.2 mm. It can be understood that the first channel 1311 and the second channel 1312 in the sound pickup channel 131 communicate with each other and form a certain angle, and this angle can be 90°, which avoids the direct communication between the microphone 151 and the outside world and also has a certain protective effect on the components in the accommodation cavity 14. At the same time, the dimensions of the first channel 1311 and the second channel 1312 are limited. Referring to Figure 5 Figure, the length of the first channel 1311 is L1, and the diameter is D1, where 1.8 mm < L1 < 4.2 mm, 0.8 mm < D1 < 2.7 mm; the length of the second channel 1312 is L2, and the diameter is D2, where 2 mm < L2 < 8 mm, 0.8 mm < D2 < 2.2 mm. In this way, the dimensions of the sound pickup channel 131 are controlled, and the influence of the setting of the sound pickup channel 131 on the structure of the support frame 13 is reduced.

[0047] The embodiment of the utility model arranges the first channel and the second channel vertically, and avoids direct connection between the recording component and the outside through the corner, thereby preventing water or dust from entering the recording component, protecting the parts and extending the service life. At the same time, the size of the sound pickup channel is further limited to optimize the structure of the product.

Among them, the processing circuit board 16 has a fixing seat 161, and the transfer circuit board 17 is electrically connected to the fixing seat 161. It can be understood that the microphone 151 is arranged on the connecting circuit board 152, the connecting circuit board 152 receives the sound signal from the microphone 151, and converts the sound signal into an electrical signal, the connecting circuit board 152 is connected to the transfer circuit board 17, the transfer circuit board 17 receives the electrical signal from the connecting circuit board 152, and transmits the electrical signal to the processing circuit board 16, and the data from the connecting circuit board 152 is processed by the processing circuit board 16, so as to realize the recording and storage of external sounds. At the same time, a fixing seat 161 is arranged on the processing circuit board 16, part of the transfer circuit board 17 is stably connected to the fixing seat 161, and the other part is installed on the support frame 13 to ensure stable signal transmission.

[0049] Part of the adapter circuit board 17 is stably connected to the fixing seat 161, and the other part is installed on the second housing 12, so that the adapter circuit board 17 is stably fixed in the accommodating cavity 14. In addition, the multiple connection circuit boards 152 are first aggregated through the adapter circuit board 17, and then uniformly electrically connected to the fixing seat 161 on the processing circuit board 16, which improves the convenience and reliability of the overall electrical connection.

[0050] The embodiment of the utility model can not only improve the simplicity and reliability of the overall electrical connection by stably setting the adapter circuit board in the accommodating cavity, but also prevent the parts from shaking in the accommodating cavity, thereby better ensuring the stable transmission of sound into electrical signals and the sound quality recorded by the recording component, optimizing the recording function of the headphone compartment, and improving product quality.

[0051] In some embodiments, Figure 1As shown, the earphone case 1 further includes a display screen 18 for at least displaying the working state of the recording component 15. The display screen 18 is connected to the first housing 11. It can be understood that the display screen 18 is provided on the first housing 11, and the working state of the earphone case 1 is displayed through the display screen 18, so that data such as the remaining power of the earphone case 1 can be obtained intuitively. At the same time, the display screen 18 can also be used to display the working state of the recording component 15, so as to intuitively know whether the recording component 15 is turned on or off. When the display screen 18 is a touch screen, the recording component 15 can also be controlled to be turned on or off through the display screen 11, further improving the convenience of use.
