Detailed Description

The utility model is explained in more detail below with reference to the figures and examples.

As shown in fig. 1-3: a preposed ball-top high-sound coaxial loudspeaker comprises a first folding ring 1, a first voice coil 2, a basin frame 3, a first vibrating diaphragm 4, a damper 5, a first washer 6, a first magnet 7, a T-shaped iron 8, a second washer 11, a U-shaped iron 2, a support 13, a second vibrating diaphragm 14, a second folding ring 15, a second voice coil 16 and a second magnet 17, wherein a flange wall of the T-shaped iron is fixedly connected with the bottom of the basin frame, a through hole is formed in the center of the T-shaped iron, the top surface of the flange is fixedly connected with the first magnet, the top end of the first magnet is fixedly connected with the first washer, a voice coil gap is reserved between the first washer and the side wall of the T-shaped iron, the bottom end of the support is fixedly arranged in the through hole, the U-shaped iron is arranged on the inner side of the support close to the top end, the top of the U-shaped iron is fixedly connected with the second magnet, the second washer at the top of the magnet is fixedly connected with the second washer, a gap is reserved between the second vibrating diaphragm and the side wall of the U-shaped iron, the inner ring is fixedly connected with the second vibrating diaphragm, keep away from between the lateral wall of two tip inserts of voice coil loudspeaker voice coil of vibrating diaphragm two and china department and U-shaped iron, roll over the basin mouth edge fixed connection of the outer lane of ring one and basin frame, roll over the inner circle of ring one and a vibrating diaphragm fixed connection, on vibrating diaphragm one and the inner circle of bullet ripples are connected to voice coil loudspeaker voice coil one respectively, the outer lane of bullet ripples and the lateral wall fixed connection of basin frame, the voice coil loudspeaker voice coil one set is established in the support outside, the stiff end of voice coil loudspeaker voice coil one sets firmly perpendicularly in the bullet ripples bottom surface.

The loudspeaker adopts a high-pitch and middle-pitch coaxial structure, and solves the problem of phase difference of high and middle frequencies under the condition of not enlarging the box body, so that the unbalanced sense of hearing disappears. Meanwhile, the two loudspeakers are on the same axis, so that the range of the perfect listening position is large.

Sound absorbing material (such as sound absorbing cotton material) can be placed in the support 13 to adjust the upper and lower limits of the high pitch.

The loudspeaker is further provided with a sound guide horn 9, the bottom of the sound guide horn 9 is connected with the circumferential top end of the support 13 through a corrugated rim support 10, the whole sound guide horn is located in a gap between the first vibrating diaphragm and the second vibrating diaphragm, the height of the sound guide horn is higher than that of the outer ring of the corrugated rim, and the sound guide horn is provided with smooth radians which incline and expand outwards and are close to two sides of the vibrating diaphragm.

Specifically, sound is emitted through vibration of the diaphragm, and after the sound guide horn 9 is arranged, the angle of sound diffusion can be increased. For example, the original sound production angle is 70 °, and after sound guidance, the sound diffusion angle can reach 120 ° through the smooth radian of the sound guidance horn.

That is, the size of the sound is directly related to the sound guide horn 9, and the higher the radian of the horn (flared), the higher the ductility of the high frequency. Therefore, the loudspeaker can adjust the radian of the horn according to the sound characteristics, so that the sound diffusion angle is increased, the high-frequency performance is optimized, the high-frequency energy sense is increased, the sound is amplified, and people can hear finer sound.

Further, the corrugated rim of the conventional speaker is convex, so that when the diaphragm vibrates to produce sound, sound wave diffusion can be hindered, sound loss is caused, and distortion is generated. Therefore, one part of the corrugated rim is arranged to be concave, so that the diffusion of sound waves is not influenced, and sound distortion is not caused.

The first bending ring is concave, the second bending ring is convex, and the whole vibrating diaphragm is in a shape close to a sphere to form a spherical top structure.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the utility model. The technical scope of the present invention is not limited to the content of the specification, and the protection scope must be determined by the scope of the claims.
