Description

Technical Field

[0001] The utility model relates to the technical field of speakers, and particularly relates to a coaxial speaker which is convenient to assemble. Background Art

[0002] A speaker is a transducer that converts an electrical signal into a sound signal. 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 sound effect, it is the most important component. There are a wide variety 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 produce sound. With the development of technology and society, various speakers have emerged, so the coaxial speaker has emerged, that is, two speakers are installed on the same axis, respectively responsible for reproducing high frequencies and mid-bass.

[0003] After retrieval, the Chinese utility model patent with the patent application number CN202021466827.9 discloses a new type of coaxial speaker, which is assembled by two components, namely a mid-bass speaker and a high-frequency speaker. Both the mid-bass speaker and the high-frequency speaker have independent magnetic circuit sound production systems. The high-frequency speaker is directly bonded and fixed on the upper part of the mid-bass speaker cone and voice coil, covering the upper part of the center of the mid-bass magnetic circuit. When the bass unit works in the pure bass state, the high-frequency speaker does not work and only functions as a dust cover for the mid-bass speaker, and at the same time can effectively improve the low-frequency effect of the mid-bass speaker. When the bass unit works in the full-frequency state, the mid-bass speaker and the high-frequency speaker can independently produce sound at the same time. It is more suitable for application in ultra-thin subwoofers, with good bass effect. It can switch to the full-frequency working mode without installing another high-frequency speaker, can be conveniently installed under the car seat to make up for the insufficient bass of the original car, or can directly use the full-frequency working mode.

[0004] Another example is the Chinese utility model patent with the patent application number CN202120559079.7, which discloses a dual voice coil micro speaker. The dual voice coil micro speaker includes two units, namely a bass unit and a high-frequency unit. The bass unit provides the bass part, and the high-frequency part is superimposed on the high-frequency part of the high-frequency unit. The high-frequency unit attenuates the unnecessary bass part through a frequency division circuit and provides the high-frequency part. The high-frequency unit is coaxially distributed in the bass unit, and the bass unit and the high-frequency unit share their respective magnetic circuit devices. The magnetic circuit of the bass unit applies a dual magnet system composed of a bass unit magnet and a high-frequency unit magnet. This dual voice coil micro speaker reduces the volume after stacking the two units by reasonably sharing the magnetic circuit devices between the two units, making the dual voice coil micro speaker more thin and has the cooperation of the high-frequency diaphragm positioning step and the step for avoiding assembly interference.

[0005] Although the existing coaxial speakers can meet the basic usage requirements, the high-frequency brackets among them are all fixed by screw connection, resulting in a relatively complex internal structure, a cumbersome assembly process, inconvenience in assembly, and a high manufacturing cost. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a coaxial speaker that is convenient to assemble in view of the above-mentioned defects of the prior art. By installing the high-frequency unit on the high-frequency bracket and directly inserting the bottom of the high-frequency bracket into the inner side of the upper end of the T-iron, the overall structure is relatively simple, without the need for screw installation, simplifying the assembly process, being more convenient to assemble, thereby being able to improve the yield rate and having a lower manufacturing cost.

The spider and the voice coil are both installed inside the chassis. The bottom of the high-frequency unit is inserted into the inside of the high-frequency bracket. The bottom of the high-frequency bracket sequentially penetrates through the diaphragm, the voice coil, the spider, the chassis, the clamping plate, and the magnet and is inserted into the inner side of the upper end of the T-iron.

[0009] Preferably, a plug-in portion is provided at the bottom of the high-frequency bracket, and a plug-in groove adapted to the plug-in portion is opened at the upper end of the T-iron.

[0013] Preferably, a wiring terminal electrically connected to the voice coil is provided on the chassis, and the surround is connected to the edge of the chassis.

[0014] With the above technical solution, a coaxial speaker provided by the utility model has the following beneficial effects: The bullet wave and the voice coil in the coaxial speaker are both installed inside the chassis. The bottom of the tweeter unit is inserted inside the tweeter bracket. The bottom of the tweeter bracket sequentially penetrates through the diaphragm, the voice coil, the bullet wave, the chassis, the clamping plate and the magnet and is inserted inside the upper end of the T-iron. During installation, directly install the tweeter unit on the tweeter bracket, and directly insert the bottom of the tweeter bracket sequentially through the diaphragm, the voice coil, the bullet wave, the chassis, the clamping plate and the magnet and insert it inside the upper end of the T-iron. Finally, apply glue for fixation.
