TECHNICAL FIELD

[0001] The utility model relates to acoustics technical field more specifically, it is related to a novel high sound quality loudspeaker. BACKGROUND

[0002] As the core component in audio equipment, loudspeaker undertakes the key task of converting electrical signal into sound signal, and its performance is directly related to the sound quality performance of audio equipment. Loudspeaker is the weakest device in audio equipment, but it is also the most important component for sound effect.

[0003] With the development of loudspeaker industry, the types and structures of loudspeakers are becoming more and more rich. Audio power is converted into sound by electromagnetic, piezoelectric or electrostatic effect, which makes the cone or diaphragm vibrate and resonate with the surrounding air. In the process of production and assembly of traditional loudspeakers, the assembly and fixation of the magnet, the magnet and the magnetic guide in the magnetic circuit system, and the assembly and fixation of the magnetic circuit system and the basket are generally fixed by different adhesives. This traditional way of using adhesive has certain limitations in the production of loudspeakers, and the process is complicated, the adhesive takes a long time to dry, which not only affects the efficiency of production and assembly, but also easily brings adverse effects on the appearance of the product itself.

[0004] Chinese patent with publication number CN214045993U discloses a loudspeaker and a sound box, which connects the magnetic guide to the basket inside, so that the whole magnetic circuit system can be relatively fixed with the basket. At the same time, connection holes are opened in the magnet and the magnet, and fixing holes are opened in the magnetic guide.

When the air flow is blocked in the magnetic circuit system area, the propagation efficiency of sound waves will be reduced, the clarity and dynamic range of sound will be limited, and the overall sound quality performance of the loudspeaker will be affected.

[0028] It should be noted that the Chinese patent with publication number CN214045993U discloses a loudspeaker and a sound box, which connects the magnetic member to the basin frame in a detachable manner, so that the overall magnetic circuit system can be relatively fixed with the basin frame. The connecting hole is formed in the magnet member and the dust cap, and the fixing hole is formed in the magnetic member. The magnet member and the dust cap are detachably fixed on the magnetic member by passing the connecting member through the connecting hole and the fixing hole. Through this connection method, the assembly of the magnetic circuit system itself or the assembly of the magnetic circuit system and the basin frame does not need to be fixed by using glue, which significantly improves the production efficiency and product quality.

[0029] In the working principle of the loudspeaker, the effective vibration of the diaphragm depends on the smooth flow of the surrounding air to form sound waves and radiate outward. However, the magnet system is directly arranged in the basin, and when the voice coil vibrates and drives the diaphragm to produce sound, the layout of the magnetic circuit system will directly affect the smoothness of the airflow of the diaphragm in the direction of the magnetic circuit system. The airflow is blocked in the magnetic circuit system area, which will cause the propagation efficiency of the sound waves to decrease, the clarity and dynamic range of the sound to be limited, and thus affect the overall sound quality performance of the loudspeaker.

[0030] As Figures 1-5As shown, the embodiment provides a new high-quality loudspeaker, the magnetic circuit system 20 is detachably arranged in the interior of the frame 10, facilitating the assembly and maintenance of the magnetic circuit system 20 and the frame 10, and the air flow exchange channel 30 is arranged through the frame 10 and the magnetic circuit system 20, so that the vibration system 40 of the loudspeaker can effectively discharge the excess air in the area of the magnetic circuit system 20 during the sound production process, while supplementing fresh air, adjusting the pressure balance inside the loudspeaker, reducing distortion, and ensuring that the loudspeaker can present clear, dynamic and balanced sound quality effects at different frequencies.

[0031] Specifically, the new high-quality loudspeaker comprises a loudspeaker body 100, the loudspeaker body 100 comprises a frame 10 and a magnetic circuit system 20 arranged in the frame 10, the frame 10 is detachably connected with the magnetic circuit system 20, and the frame 10 and the magnetic circuit system 20 are provided with an air flow exchange channel 30 penetrating therethrough, so that the vibration system 40 of the loudspeaker body 100 exchanges air flow with the outside in the direction of the magnetic circuit system 20.

[0032] In one embodiment, the air flow exchange channel 30 comprises a main air flow channel 31 and a plurality of auxiliary air flow channels 32, and the plurality of auxiliary air flow channels 32 are arranged around the main air flow channel 31. The main air flow channel 31 is arranged at the center of the frame 10, and the main air flow channel 31 can directly act on the central region of the vibration system 40. Through the main air flow channel 31, the central region of the vibration system 40 can exchange air flow with the outside environment efficiently during the sound production process of the loudspeaker, effectively discharging the excess air generated by vibration, while introducing fresh air, thereby reducing the sound quality distortion caused by air pressure changes.

[0033] The plurality of auxiliary air flow channels 32 are arranged around the main air flow channel 31, the auxiliary air flow channels 32 act on the periphery of the vibration system 40, and the auxiliary air flow channels 32 complement the main air flow channel 31, further enhancing the air flow exchange capacity between the inside of the loudspeaker and the outside, and ensuring the uniform response of the vibration system 40 at different frequencies, avoiding the decrease of sound quality caused by local air pressure imbalance.

[0034] In one embodiment, the magnetic circuit system 20 comprises a first magnetic conducting member 21, a magnet member 22 and a second magnetic conducting member 23 arranged in sequence, the first magnetic conducting member 21 is detachably connected with the frame 10, the magnet member 22 is clamped between the first magnetic conducting member 21 and the second magnetic conducting member 23, the bottom surface of the second magnetic conducting member 23 abuts against the frame 10, and the magnetic circuit system 20 can be stably installed in the frame 10.

[0039] Specifically, the side surface of the second magnetic member 23 is provided with a recess 233 for reducing the contact between the second magnetic member 23 and the yoke 10, thereby forming a gap between the second magnetic member 23 and the yoke 10 to constitute the auxiliary airflow channel 32.
