Detailed implementation manners

[0029] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. Now, with reference to the drawings, the preferred embodiments of the present utility model will be described in detail.

[0030] The embodiment of the present utility model provides an earphone. As Figures 1 to 4 shown, the earphone includes a housing 1. A sound cavity 11 is formed inside the housing 1. A battery bracket 2, a battery 3, a speaker 4, and a speaker bracket 5 are arranged inside the sound cavity 11. An end of the housing 1 is provided with a sound outlet 12. The speaker bracket 5 is installed on the housing 1 near the sound outlet 12. The speaker 4 is installed on the speaker bracket 5 and the housing 1 near the sound outlet 12, and is hermetically connected to the speaker bracket 5 and the housing 1 to form a front cavity 111 on one side of the sound outlet 12. The earphone is provided with a front pressure relief hole 521 communicating the front cavity 111 with the outside.

[0031] In the area of the sound cavity 11 away from the front cavity 111, the battery bracket 2 is installed on the housing 1, and the battery 3 is installed on the side of the battery bracket 2 away from the speaker 4; the battery bracket 2, the speaker 4, and the housing 1 are hermetically connected to form a rear cavity 112 in a part of the sound cavity 11. A rear pressure relief hole 13 communicating the rear cavity 112 with the outside is formed on the housing 1.

[0032] The earphone of the present utility model forms a front cavity 111 by sealing and connecting a speaker 4, a speaker bracket 5 and a housing 1 together. At the same time, by arranging a battery bracket 2 and cooperating with the speaker 4 and the housing 1 to form an independent rear cavity 112, it can ensure the normal functions of the front pressure relief hole 521 and the rear pressure relief hole 13 while the spaces of the front cavity 111 and the rear cavity 112 are relatively small, which can save the remaining space of the sound cavity 11. The remaining space can be used to assemble other accessories, which is beneficial to the miniaturization of the earphone.

[0033] Specifically, the technical solution of the present utility model is particularly applicable to ANC (Active Noise Cancellation) active noise-canceling Bluetooth earphones. The gaps at the assembly positions of the battery bracket 2, the speaker 4 and the housing 1 can be sealed with glue to achieve the sealed connection of the assembly between the battery bracket 2, the speaker 4 and the housing 1 and ensure the sealing of the rear cavity 112. Similarly, the gaps at the assembly positions of the speaker 4 with the housing 1 and the speaker bracket 5 can also be sealed with glue to achieve the sealed connection of the assembly between the speaker 4, the housing 1 and the speaker bracket 5 and ensure the sealing of the front cavity 111. The battery 3 powers the earphone, and it is a rechargeable battery 3, which will not be elaborated here. The sound generated by the speaker 4 is transmitted out through the sound outlet 12.

[0034] Specifically, as Figure 2 and Figure 5 shown, a raised frame edge 21 is provided on the side of the battery bracket 2 corresponding to the rear pressure relief hole 13, and a hole channel 211 communicating the rear pressure relief hole 13 and the rear cavity 112 is opened on the extended part of the raised frame edge 21 towards the rear cavity 112. The raised frame edge 21 can facilitate the setting of a tuning mesh cloth between the rear pressure relief hole 13 and the battery bracket, and further opening the hole channel 211 on the extended part of the raised frame edge 21 towards the rear cavity 112 can ensure the communication between the rear pressure relief hole 13 and the rear cavity 112. Further, a concave area 212 is provided on the part of the raised frame edge 21 corresponding to the side of the battery bracket 2. The setting of the concave area 212 can further increase the gap between the raised frame edge 21 and the rear pressure relief hole 13 and improve the communication degree between the rear cavity 112 and the outside.

[0035] As Figure 6 shown, a first through port 51 is opened on the speaker bracket 5, and the first through port 51 is arranged corresponding to the sound outlet 12. In this solution, the first through port 51 is further opened on the speaker bracket 5, and the first through port 51 can ensure the communication between the front cavity 111 and the sound outlet 12 and avoid the blockage of the sound outlet 12 by the speaker bracket 5. Specifically, the opening size of the first through port 51 can be slightly smaller than that of the sound outlet 12. A mesh cover can be further arranged at the sound outlet 12 to block the first through port 51 and its speaker bracket 5. The shape of the first through port 51 can be set as needed and will not be specifically limited here.

[0036] The speaker bracket 5 is provided with a mounting protrusion 52, the housing 1 is provided with a mounting opening 14, the mounting protrusion 52 is embedded in the mounting opening 14, and the front pressure relief hole 521 is provided on the mounting protrusion 52. In this solution, by providing the mounting protrusion 52 on the speaker bracket 5 and providing the mounting opening 14 on the housing 1, the mounting protrusion 52 is embedded in the mounting opening 14, so that the speaker bracket 5 and the housing 1 are installed and matched, and the installation firmness of the speaker bracket 5 is improved. At the same time, the front pressure relief hole 521 is directly provided on the mounting protrusion 52 to simplify the structural design. Specifically, two front pressure relief holes 521 can be provided on the mounting protrusion 52.

[0037] like Figures 6 to 8 As shown, beside the first through hole 51, a first through hole 53 is provided on the speaker bracket 5, and the earphone includes a noise reduction microphone 6, which is installed on the speaker bracket 5 at the first through hole 53, and the first through hole 53 is at the sound outlet 12. The noise reduction microphone 6 is a special microphone used to reduce the impact of environmental noise, which can help users to communicate or record sounds more clearly in a noisy environment. The noise reduction microphone 6 uses noise cancellation technology to collect noise in the environment and compare it with the main sound source (such as human voice), and then outputs an opposite sound wave signal to offset the environmental noise, thereby reducing the noise level heard by the user. The speaker bracket 5 of this solution can provide an installation position and installation structure for the noise reduction microphone 6, and at the same time, a first through hole 53 is provided on the speaker bracket 5, and the first through hole 53 is set at the sound outlet 12 to facilitate the sound collection of the noise reduction microphone 6. Specifically, installing the noise reduction microphone 6 at a position close to the sound outlet 12 can more effectively capture the audio signal for noise reduction processing. This position can more accurately capture sound signals for noise reduction processing when the user is speaking or listening, help reduce interference and improve the accuracy of sound collection, and minimize the impact of noise from the external environment, thereby improving the noise reduction effect.

[0038] The earphone includes a flexible circuit board 7, a noise reduction microphone 6 is electrically connected and mounted on the flexible circuit board 7, mounting posts 57 are provided on both sides of the first through hole 53, and the flexible circuit board 7 is mounted on the two mounting posts 57. By providing the mounting posts 57 on both sides of the first through hole 53, the flexible circuit board 7 can be firmly mounted inside the earphone, providing good support and protection, thereby effectively preventing the flexible circuit board 7 from being damaged by accidental collision or vibration during use. The noise reduction microphone 6 is electrically connected and mounted on the flexible circuit board 7, and the flexible circuit board 7 is fixed by the mounting posts 57. This design can ensure that the connection between the noise reduction microphone 6 and the flexible circuit board 7 is stable and reliable, and functional problems caused by poor connection can be avoided. By fixing the flexible circuit board 7 in position using the mounting posts 57, the assembly process can be made simpler and more efficient. The mounting posts 57 help ensure the correct position of the circuit board, and also help with subsequent maintenance and repair.

[0039] The flexible circuit board 7, also known as a flexible printed circuit board (FPC), is a soft circuit board composed of a flexible substrate (usually a polyester film or a polyamide film) and a conductive circuit. The flexible circuit board 7 can be bent, folded and curved, and can better adapt to complex internal structures and space constraints, thereby achieving a more flexible and compact layout. Specifically, a main control circuit board 8 is also provided in the headset, and the noise reduction microphone 6 is electrically connected to the main control circuit board 8 through the flexible circuit board 7, so as to realize the collection, transmission and processing of sound signals. In addition, the battery 3 and the speaker 4 are also electrically connected to the main control circuit board 8 directly or indirectly to realize the normal operation of the battery 3 and the speaker 4.

[0040] The edge of the speaker bracket 5 is provided with a guide support block 54, and the flexible circuit board 7 is guided to the side of the speaker bracket 5 away from the front cavity 111 through the guide support block 54, and the edge of the speaker 4 is supported on the guide support block 54. The guide support block 54 helps to guide the flexible circuit board 7 to the correct position, ensuring that the circuit board is correctly connected to the speaker bracket 5 and is located in the appropriate position. The edge of the speaker 4 supported on the guide support block 54 can provide additional support and stability to prevent the speaker 4 from loosening or being damaged due to vibration or movement during use. By supporting the edge of the speaker 4 on the guide support block 54, it can be ensured that the connection between the speaker 4 and the flexible circuit board 7 is stable and reliable, avoiding performance problems caused by improper connection.

[0041] Furthermore, a guide groove 55 extending from the edge to the mounting column 57 is provided on the side of the speaker bracket 5 facing the front cavity 111. The flexible circuit board 7 is guided to the noise reduction microphone 6 through the guide groove 55 and is electrically connected to the noise reduction microphone 6. The provision of the guide groove 55 can help accurately position the flexible circuit board 7, ensure that it is connected to the noise reduction microphone 6 at a specific position, and help improve the accuracy and stability of the connection. The provision of the guide groove 55 can also effectively protect the flexible circuit board 7 from accidental damage or excessive bending, thereby extending its service life and improving the reliability of the headset, and facilitating the assembly between the speaker bracket 5 and the flexible circuit board 7.

[0042] On the opposite side of the guide support block 54, the edge of the speaker bracket 5 is provided with a support edge 56, and the inner side surface of the support edge 56 is provided with a step surface 561, and the edge of the speaker 4 is supported on the step surface 561. The edge of the speaker 4 supported on the step surface 561 can provide a stable support, ensuring that the speaker 4 can be properly aligned and maintain a stable connection during the installation process, avoiding problems caused by looseness or displacement. Through the design of the step surface 561, the edge of the speaker bracket 5 can be more easily aligned with the support edge 56, ensuring the correct positioning of the speaker 4.
