Description

Technical Field

[0001] This utility model belongs to the field of loudspeaker technology, specifically a headphone loudspeaker with a rubber-coated base. Background Technology

[0002] Headphone speakers typically have tuning paper installed at the air intake. The function of the tuning paper is to provide good dust and water resistance and to dampen sound waves, effectively suppressing sound spikes and improving sound frequency characteristics. As shown in the published technical document "CN204929219U, A novel diaphragm for headphone speakers and a headphone speaker having the novel diaphragm", the assembly process requires stacking and installing the components one by one, which is quite cumbersome. Moreover, the tuning paper is easily wrinkled during assembly, which is difficult to detect. Wrinkled tuning paper will affect the overall sound quality of the speaker and requires disassembly and replacement.

[0003] In addition, existing technologies already include a method of setting a soft base at the bottom position, which can achieve a vibration reduction effect. This application will improve its structure. Utility Model Content

[0004] The purpose of this invention is to provide a base-coated headphone speaker to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A base-coated headphone speaker includes a flexible base, a rigid fixing seat fixed in the flexible base, a magnetic circuit assembly fixed in the rigid fixing seat, a voice coil located on the outer periphery of the magnetic circuit assembly, the upper end of the voice coil being connected to a diaphragm, the outer edge of the diaphragm being fixedly connected to the upper edge of the flexible base, and air holes located on the flexible base or the rigid fixing seat. It also includes a housing located above the diaphragm, the outer periphery of which is connected to the outer edge of the diaphragm.

[0007] In a further technical solution, the flexible base has a groove on the outside of the rigid fixing seat, and the bottom of the groove has air holes.

[0008] In a further technical solution, the pores are conical and gradually extend outwards.

[0009] In a further technical solution, the rigid fixing base is provided with air holes, and the flexible base is provided with clearance positions corresponding to the positions of the air holes.

[0010] In a further technical solution, the surface of the rigid fixing seat is provided with a slot, the flexible base is provided with an installation cavity for accommodating the rigid fixing seat, and the side wall of the installation cavity is provided with a locking strip that engages with the slot.

[0011] In a further technical solution, a washer is provided between the diaphragm and the flexible base, and the upper end surface of the flexible base is higher than the upper end surface of the rigid fixing base, so that an air cavity is formed between the side wall of the flexible base and the diaphragm, and the air cavity is connected to the groove.

[0012] In a further technical solution, the outer shell is composed of multiple annular steps, with the bottom surface of the outermost annular step corresponding to the upper outer edge of the flexible base.

[0013] The beneficial effects of this utility model are:

[0014] In this invention, the use of tuning paper is eliminated. Instead, a soft base is used to absorb the sharp part of the sound wave, achieving the same goal of improving sound quality.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please refer to Figure 1-5 ;

[0024] This utility model aims to further optimize the original structure and improve assembly efficiency. Specifically, it includes a flexible base 1, within which a rigid fixing seat 2 is fixed. In this embodiment, the flexible base 1 can be made of silicone or rubber, providing moderate deformation. The rigid fixing seat 2 can be injection molded from plastic or made of metal. A magnetic circuit assembly 3 is fixed within the rigid fixing seat 2. The magnetic circuit assembly 3 can refer to existing technologies and is not limited in this application. A voice coil 4 is located on the outer periphery of the magnetic circuit assembly 3. The upper end of the voice coil 4... The diaphragm 5 is connected to the outer edge of the diaphragm 5 and fixedly connected to the upper edge of the flexible base 1. An air hole 12 is provided on the flexible base 1 or the rigid fixed base 2. When the speaker is in operation, the diaphragm 5 vibrates due to the interaction between the magnetic circuit assembly 3 and the voice coil 4. The air inside the speaker also vibrates and exchanges gas through the air hole 12. The air vibrating in the speaker can absorb some of the vibration through the flexible base 1, especially suppressing the sharp part of the sound wave, thus improving the sound quality, which can achieve the same effect as the tuning paper.

[0025] One possible solution for the vent configuration is that the flexible base 1 has a groove 11 on the outside of the rigid fixing base 2, and the bottom of the groove 11 has a vent 12. It should be noted that the size of the vent 12 needs to be determined according to the current speaker positioning, and the size of the vent 12 is determined according to the high and low frequencies. However, it is smaller than the vent 12 of the prior art that requires the setting of the tuning paper. Preferably, the hole is conical and gradually extends outward to better facilitate gas exchange.

[0026] Another option is that the rigid fixing base 2 is provided with air holes 12, and the flexible base 1 is provided with clearance positions 13 corresponding to the positions of the air holes 12;

[0027] In this embodiment of the utility model, a housing 8 is also included. The housing 8 is located above the diaphragm 5, and the outer periphery of the housing 8 is connected to the outer edge of the diaphragm 5. It should be noted that the lower surface of the outer edge of the diaphragm 5 is directly connected to the upper edge of the flexible base 1 or indirectly connected to the upper edge of the flexible base 1 through the washer 6, while the upper surface is connected to the housing 8. As is well known, the diaphragm 5 is very important for the sound quality of the speaker. Usually, a protective shell is provided on the headphones, and it needs to be very careful during assembly. In addition, as mentioned above, the flexible base 1 may reduce the amplitude of the diaphragm 5 and affect the rigidity. Therefore, by setting the housing 8, the outer edge of the diaphragm 5 is fixed so that it is not affected by the flexible base 1. Secondly, the pre-set housing 8 is much simpler to connect than the headphone housing 8, the installation space is much larger, it is easier to operate, and damage to the diaphragm 5 is avoided. Of course, several through holes are provided on the housing 8 to allow sound waves to be transmitted to the external space.

[0028] In this utility model, the use of tuning paper is eliminated. Instead, the sharp part of the sound wave is absorbed by the soft base 1, which achieves the same purpose of improving sound quality. During the assembly process, the step of installing tuning paper can be saved, and wrinkles can be avoided, which can improve work efficiency and yield.

[0029] In addition, although there are existing methods for installing a flexible base 1, this utility model changes the purpose of the flexible base 1, so that it not only has a vibration reduction effect, but also absorbs noise.

[0030] In this embodiment of the utility model, the flexible base 1 and the rigid fixing seat 2 are connected by a snap-fit ​​method, rather than by glue, because glue would affect the performance of the flexible base 1. More specifically, the surface of the rigid fixing seat 2 is provided with a slot 21, and the flexible base 1 is provided with an installation cavity for accommodating the rigid fixing seat 2. The side wall of the installation cavity is provided with a locking strip that engages with the slot 21.

[0031] In this embodiment of the utility model, a washer 6 is provided between the diaphragm 5 and the soft base 1. The washer 6 is located at the connection between the diaphragm 5 and the soft base 1. Its main function is to raise the diaphragm 5. Secondly, the washer 6 can be made of rigid material to prevent the soft base 1 from excessively absorbing the vibration generated by the diaphragm 5 when the diaphragm 5 moves, so as to reduce the amplitude of the diaphragm 5 and affect the sound quality.

[0032] In addition, the upper surface of the flexible base 1 is higher than the upper surface of the rigid fixed base 2, so that an air cavity 7 is formed between the side wall of the flexible base 1 and the diaphragm 5. Since the diaphragm 5 is raised a bit by the gasket 6, the air cavity 7 will also be larger. Of course, an air cavity 7 will still be formed even without the gasket 6. The air cavity 7 can better present the bass effect, and the air cavity 7 is connected to the groove 11, which can better absorb noise.

[0033] In addition, the outer shell 8 is composed of multiple annular steps. The bottom surface of the outermost annular step corresponds to the upper outer edge of the flexible base 1. The annular steps not only strengthen the structure of the outer shell 8, but also gradually shrink inward to reduce the volume of the outer shell 8. They can also provide a mounting and fixing position that adapts to the earphone shell 8, making it easier to install into the earphone.
