[0001] The utility model relates to the technical field of flat speakers, in particular to an ultra-thin flat bass speaker. Background Art
[0002] A speaker is a transducer that converts electrical signals into sound signals. The performance of the speaker has a great impact on the sound quality. The speaker is the weakest component in the audio equipment, but for the audio effect, it is also the most important component. There are many types of speakers, and the prices vary greatly. The audio electrical energy makes its paper cone or diaphragm vibrate through electromagnetic, piezoelectric or electrostatic effects and resonate with the surrounding air to emit sound.
[0003] However, when this structure is applied to an ultra-thin flat bass speaker, due to the limitation of its own structure, when applied to an ultra-thin flat plate, the overall volume of the speaker needs to be extremely compressed. At this time, the sound generated by the vibration of the internal components of the speaker cannot be effectively transmitted, resulting in poor bass effect of the overall sound of the flat plate and unable to meet the daily use requirements. Therefore, it is urgent to design an ultra-thin flat bass speaker to solve the above problems. Summary of the Utility Model
[0004] The purpose of the present utility model is to provide an ultra-thin flat bass speaker to solve the problem that in the application of the existing structure to an ultra-thin flat bass speaker, due to the limitation of its own structure, when applied to an ultra-thin flat plate, the overall volume of the speaker needs to be extremely compressed. At this time, the sound generated by the vibration of the internal components of the speaker cannot be effectively transmitted, resulting in poor bass effect of the overall sound of the flat plate and unable to meet the daily use requirements as mentioned in the above background art.
[0005] To achieve the above purpose, the present utility model provides the following technical solution: An ultra-thin flat bass speaker, including a chassis, a drum paper is fixedly connected to the surface of the chassis, a spider is movably arranged inside the chassis, a cotton thread is arranged at the center inside the spider, and dust caps are arranged on both sides of the surface of the spider;
[0006] A U-shaped iron, and a U-shaped iron is arranged at the center of the bottom of the chassis.
[0007] Preferably, a gasket is arranged on the inner bottom wall of the U-shaped iron, and a main magnet is arranged on the surface of the gasket.
[0008] Preferably, a washer is arranged on the surface of the main magnet, and a secondary magnet is arranged on the surface of the washer.
[0009] Preferably, the gasket, the main magnet, the washer and the secondary magnet are adapted to the inside of the U-shaped iron.
[0010] Preferably, terminals are arranged at both bottom sides of the chassis.
[0011] Preferably, a voice coil is arranged at the center inside the speaker frame.
[0012] Preferably, an outer rubber ring is sleeved on the outer surface of the diaphragm.
[0013] Preferably, a limit card slot is opened inside the speaker frame.
[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0015] For this ultra-thin flat panel bass speaker, by setting the speaker frame, diaphragm, spider, cotton thread, dust cap, terminal, voice coil, outer rubber ring and limit card slot, the device can perform better sound production operations within the ultra-thin flat panel. During actual use, the staff can assemble the cotton thread and the dust cap with the spider respectively, and then install the spider, cotton thread and dust cap as a whole into the limit card slot inside the speaker frame. Finally, the diaphragm is installed on the surface of the speaker frame through the outer rubber ring sleeved on its outer surface to form a radiation vibration system. At this time, the terminals on both sides of the speaker frame can be adaptively installed to quickly complete the assembly and use. The device adopts an ultra-thin flat panel internal magnetic type bass speaker, which is light in weight. The radiation diaphragm system is used as the sound emitter, and the coil is used as the driving force. The radiated sound waves are propagated in an omnidirectional manner, making the sound field coverage wider, the bass deep and shocking, enabling people to hear more ideal sounds from different angles, reflecting the practicality of the device design.
[0016] For this ultra-thin flat panel bass speaker, by setting the U-shaped iron, gasket, main magnet, washer, sub-magnet and voice coil, the overall use effect of the device is further improved. During daily use, the staff can install the gasket, main magnet, washer and sub-magnet in sequence by stacking. Then, the gasket, main magnet, washer and sub-magnet are inserted into the U-shaped iron as a whole to form a magnetic circuit system, and the U-shaped iron is installed at the center position of the bottom of the speaker frame and is adaptively connected to the voice coil inside the speaker frame. The voice coil is used to cover and fix the gasket, main magnet, washer and sub-magnet inside the U-shaped iron as a whole. Such an integrated design of the U-shaped iron effectively reduces the overall volume of the device, and also has a better sound quality than similar speakers, has a wider application field, and has a simple manufacturing process, so the overall cost of the product is low, reflecting the comprehensiveness of the device design.
