Description

Technical Field

[0001] This utility model relates to the technical field of coaxial mid-high frequency speakers, and in particular to a coaxial cylindrical wave mid-high frequency speaker. Background Technology

[0002] A coaxial cylindrical wave midrange speaker places the midrange unit, which processes mid-frequency sounds, and the tweeter, which processes high-frequency sounds, on the same axis, allowing mid- and high-frequency sounds to propagate outward in the form of cylindrical waves, thus providing a clearer sound effect.

[0003] However, existing coaxial cylindrical wave midrange and tweeter designs are relatively complex, have high manufacturing costs, and are more difficult to maintain; secondly, the tweeter needs to be installed in conjunction with the midrange unit, resulting in poor independence between the midrange and tweeter units and difficulty in position adjustment.

[0004] Therefore, there is an urgent need for a coaxial cylindrical wave midrange and tweeter with a simple structure and strong independence. Utility Model Content

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] Reference Figures 1-2A coaxial cylindrical wave mid-high frequency speaker includes a speaker body 1, and also includes a mid-low frequency unit 2, a tweeter mounting bracket 3, a tweeter 4, and a tweeter horn 5 located on the same axis. The mid-low frequency unit 2 is used to process mid-low frequencies and is mounted on the speaker body. At least one tweeter 4 is mounted on the tweeter mounting bracket 3. Both ends of the tweeter mounting bracket 3 are provided with a first connecting hole 31 and a second connecting hole 32. The tweeter mounting bracket 3 and the speaker body 1 are connected through the first connecting hole 31, and the tweeter mounting bracket 3 and the mid-low frequency unit 2 are connected through the second connecting hole 32. The tweeter horn 5 is located on the side of the tweeter 4 away from the tweeter mounting bracket 3. The speaker body 1 has guide holes 11 on both sides for eliminating high-frequency standing waves.

[0018] By arranging the mid-bass unit 2, tweeter 4, and tweeter horn 5 on the same axis, coaxial sound propagation is ensured, contributing to a more consistent and clear sound field. The tweeter mounting bracket 3 ensures structural stability and allows the tweeter 4 to be installed and positioned independently of the mid-bass unit 2. Compared to traditional designs, this approach significantly simplifies the assembly process and increases flexibility. The tweeter horn 5 guides and diffuses high-frequency sound waves, improving the directivity and coverage of high-frequency sounds and reducing distortion. The airflow guide 11 reduces unnecessary sound wave reflections and interference, enhancing the overall sound quality of the speaker. This design solves the problems of poor independence between the midrange and tweeter units 4 and difficulty in position adjustment inherent in existing coaxial cylindrical wave midrange and tweeter speakers.

[0019] Specifically, the tweeter horn 5 has third connecting holes at its four corners, corresponding to the positions of the first connecting holes 31. The speaker body 1 has fourth and fifth connecting holes. The fourth connecting hole corresponds to the position of the first connecting hole 31. Bolts pass through the first connecting hole 31, the third connecting hole, and the fourth connecting hole to connect the tweeter horn 5, the tweeter mounting bracket 3, and the speaker body 1. The fifth connecting hole corresponds to the position of the second connecting hole 32. Bolts pass through the second connecting hole 32 and the fifth connecting hole to connect the mid-bass unit 2 and the tweeter mounting bracket 3. The tweeter horn 5 is installed at the output end of the tweeter unit 4, forming an integral structure. The tweeter horn 5 is a horn-shaped structure with a gradually widening opening.

[0020] The tweeter mounting bracket 3 can also be connected to the speaker body 1 and the mid-low unit 2 by magnetic attraction; specifically, the tweeter mounting bracket 3 is provided with a first magnet and a second magnet, the speaker body 1 is provided with a third magnet corresponding to the position of the first magnet, the first magnet and the third magnet attract each other, and the mid-low unit 2 is provided with a fourth magnet corresponding to the position of the second magnet, the second magnet and the fourth magnet attract each other.

[0021] In some embodiments, the mid-bass unit 2 includes a mid-bass frame, and a mid-bass diaphragm, a mid-bass voice coil, a mid-bass magnet, and a mid-bass suspension mounted on the mid-bass frame. The mid-bass frame and the mid-bass diaphragm are connected by the mid-bass suspension. The mid-bass voice coil is located between the mid-bass magnet and the mid-bass diaphragm and is connected to the mid-bass diaphragm. The mid-bass unit is mounted on the speaker body 1 through the mid-bass frame.

[0022] The mid-bass suspension connects the mid-bass frame to the mid-bass diaphragm, allowing the diaphragm to vibrate freely. The mid-bass voice coil is located in the magnetic field formed by the mid-bass magnet and connected to the mid-bass diaphragm. When current passes through the mid-bass voice coil, it drives the mid-bass diaphragm to vibrate and produce sound under the influence of the magnetic field, ensuring a fuller and more layered sound in the mid-low frequency range.

[0023] In some embodiments, the tweeter unit 4 includes a tweeter frame, and a tweeter diaphragm, a tweeter voice coil, a tweeter magnet and a tweeter suspension mounted on the tweeter frame. The tweeter frame and the tweeter diaphragm are connected by the tweeter suspension. The tweeter voice coil is located between the tweeter magnet and the tweeter diaphragm and is connected to the tweeter diaphragm. The tweeter unit 4 is mounted on the tweeter mounting bracket 3 through the tweeter frame.

[0024] By positioning the tweeter voice coil between the tweeter magnet and the tweeter diaphragm and connecting it to the tweeter diaphragm, electrical signals are effectively converted into sound waves, thereby improving the speed and accuracy of high-frequency response.

[0025] The tweeter unit 4 also includes a phase plug, which has a coaxial multi-ring structure and is positioned on the side of the tweeter diaphragm away from the tweeter voice coil. The phase plug and the center of the tweeter diaphragm are on the same axis, and the phase plug is connected to the tweeter frame by reinforcing ribs. By setting the phase plug, the phase difference between sound waves generated in different parts of the tweeter diaphragm is reduced, thereby improving the in-phase nature of the sound waves and making the sound more focused and consistent.

[0026] In some embodiments, the tweeter mounting bracket 3 is integrally formed, and the two ends of the tweeter mounting bracket 3 are arc-shaped structures that match the shape of the mid-bass unit 2.

[0027] The one-piece molded design enhances the mechanical strength and stability of the tweeter mount 3, reducing the risk of loosening or deformation due to vibration. The tweeter mount 3 is made of aluminum alloy, stainless steel, or ABS, making it robust, durable, and suitable for mass production.

[0028] In some embodiments, the speaker body 1 is also provided with a grille 12, and the mid-low unit 2, the tweeter mounting bracket 3, the tweeter unit 4 and the tweeter horn 5 are all located in the cavity formed by the grille 12 and the speaker body 1.

[0029] The mesh cover 12 effectively prevents dust, moisture or accidental impacts from damaging the mid-low frequency unit 2, tweeter mounting bracket 3, tweeter unit 4 and tweeter horn 5.

[0030] In some embodiments, the speaker body 1 is provided with connecting hooks 13 on both sides. The connecting hooks 13 include a pin at the top and a connecting groove at the bottom, with the pin and the connecting groove on the same straight line.

[0031] The hook 13 facilitates the installation and removal of multiple coaxial cylindrical wave mid-high frequency speakers, or allows the coaxial cylindrical wave mid-high frequency speakers to be mounted on a wall or bracket, making it easier to control the directionality and coverage of the sound, resulting in better sound quality from the coaxial cylindrical wave mid-high frequency speakers.
