Technical Field

[0001] The utility model relates to the technical field of a mid-range basin frame loudspeaker, in particular to a thin loudspeaker with a mid-range basin frame. Background Art

[0002] In the field of audio technology, speakers are sound output devices, and their performance directly determines the quality and listening experience of the sound. Traditional speaker designs often face problems such as poor sound quality, low sound efficiency, and large size. These problems are particularly prominent in the design of mid-range basin frames.

[0003] Traditional mid-range basin speakers are often complex in structural design, and the components are not tightly matched, which makes it easy for the sound to be distorted and attenuated during transmission. In addition, traditional speakers also have certain limitations in material selection and cannot meet the requirements of lightweight and high elasticity at the same time, thus affecting the speaker's sound efficiency and sound quality performance.

[0004] With the advancement of science and technology and the development of audio technology, the performance requirements for speakers are getting higher and higher, especially in modern audio equipment, which require speakers to have better sound performance, higher sound efficiency and smaller size. Therefore, the development of a new type of mid-range basin frame thin speaker made of materials with good elasticity has become the research focus of the industry to improve the sound efficiency and sound quality performance of the speaker.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a thin speaker with a mid-range basin frame, which has the following beneficial effects:

[0018] 1. The thin speaker of the mid-range basin frame adopts the design of hemispherical cover, which significantly improves the focus and directivity of the sound. When the current passes through the copper coil to generate a magnetic field and interacts with the magnetic field in the transfer tube, the vibration is effectively transmitted to the folded diaphragm and the sound cone. Due to the existence of the hemispherical cover, the shape and propagation direction of the sound waves emitted by the sound cone are optimized when passing through the cover, so that the sound can be propagated forward more concentratedly, which not only improves the clarity and recognition of the sound, but also makes the sound performance of the speaker in a specific direction more prominent, meeting the listening needs of users in specific scenarios.

[0019] 2. The mid-range basin frame thin speaker ensures the effective transmission of vibration through the fixed connection between the transfer tube and the folded diaphragm, and the use of the elastic ring membrane further enhances the sound propagation effect. The lightweight and elastic material enables the elastic ring membrane to vibrate along with the vibration of the basin, reducing energy loss and improving the sound efficiency. At the same time, the choice of this material also helps to improve the texture of the sound and make the sound of the speaker clearer. In addition, the design of the hemispherical cover also has a positive effect on the sound quality, by focusing and reflecting sound waves, making the sound fuller. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-3 A thin speaker with a mid-range basin frame includes a fixing seat 1, a connecting block 2 is sleeved on the upper end of the fixing seat 1, a sensor component 11 is arranged on one side of the outer end of the connecting block 2, a sound basin 3 is fixedly connected to the upper end of the connecting block 2, and a plurality of threaded holes 10 are opened around the top of the sound basin 3, wherein an elastic ring membrane 4 is arranged on the upper end of the sound basin 3, and further includes:

[0026] The sound transmission component is fixedly installed inside the fixing base 1 and is used for sound transmission.

[0027] Furthermore, a plurality of screws 6 are arranged around the upper surface of the elastic ring membrane 4 , and the screws 6 are arranged corresponding to the threaded holes 10 arranged on the upper end of the sound basin 3 and are threadedly connected, wherein a hemispherical cover 5 is arranged at the lower end of the elastic ring membrane 4 .

[0028] Furthermore, grooves are provided at four positions of the outer end of the connection block 2, wherein a connecting rod is provided at the center of the groove at one end of the connection block 2, and a sensor assembly 11 is fixedly installed at the outer end of the connecting rod.

[0029] Furthermore, the sensor assembly 11 is composed of a fixing plate 7, a positioning rod 8 and a connecting hole 9. The fixing plate 7 is fixedly mounted on the outer end of the connecting rod and is fixed by the positioning rod 8, wherein connecting holes 9 are provided on both sides of the outer end of the fixing plate 7.

[0030] Furthermore, the sound transmission component consists of a transmission tube 12, a folded diaphragm 13 and a copper coil 14, wherein the transmission tube 12 is arranged inside the fixed seat 1, and the copper coil 14 is fixedly connected to the lower end of the transmission tube 12, and the folded diaphragm 13 is fixedly arranged at the outer end of the transmission tube 12, wherein the upper end of the transmission tube 12 is correspondingly arranged inside the hemispherical cover 5.

[0031] Furthermore, the outer ring of the folded diaphragm 13 is fixedly connected to the inner wall of the connecting block 2 around one circle.

[0032] Furthermore, the elastic ring membrane 4 is made of a lightweight material with good elasticity to improve the sound efficiency and sound quality of the speaker.

[0033] Working principle: When the current receives the electrical signal through the copper coil 14, it will generate a corresponding magnetic field according to the strength of the electrical signal and interact with the magnetic field in the transmission tube 12, causing the transmission tube 12 to start vibrating. Since the transmission tube 12 is fixedly connected to the folded diaphragm 13, the folded diaphragm 13 will also vibrate with the vibration of the transmission tube 12. This vibration is fast and continuous, corresponding to the input electrical signal. The vibration of the folded diaphragm 13 is effectively transmitted to the connecting block 2 through the fixed connection between its outer ring and the inner wall of the connecting block 2. The connecting block 2 then transmits the vibration to the sound cone 3. The sound cone 3 is the main component for sound propagation. Its vibration will drive the surrounding air molecules to produce density changes, thereby forming sound waves. An elastic ring membrane 4 is arranged at the upper end of the sound cone 3. It is made of a lightweight material with good elasticity, which can further improve the sound efficiency and sound quality performance of the speaker. The elastic ring membrane 4 is threadedly connected to the threaded hole 10 on the sound cone 3 through several screws 6 on its upper end surface to ensure a tight connection between the two. When the sound basin 3 vibrates, the elastic ring membrane 4 will also vibrate, further enhancing the sound propagation effect. The hemispherical cover 5 helps to focus and reflect the sound, so that the sound can be propagated forward more concentratedly, improving the directivity and clarity of the sound.
