[0020] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0021] Please refer to Figure 1 A ring-type loudspeaker comprises a dome, a diaphragm, a voice coil and a supporting assembly, all of which are in the shape of a circular ring; the cross section of the supporting assembly is in the shape of a "concave" character, including a concave end; the diaphragm is mounted on the concave end; the dome is arranged on a side of the diaphragm away from the supporting assembly; the voice coil is arranged in the concave end and connected to the diaphragm.

[0022] From the above description, it can be seen that the beneficial effect of the utility model is that by setting the cross-section of the supporting component to be similar to a "concave" shape, the diaphragm can be mounted on the recessed end and the voice coil can also be set in the recessed end, so that the structure of the speaker is more compact and the volume of the speaker is reduced; and, by adopting a circular dome, diaphragm, voice coil and supporting component, the entire speaker is formed into a circular structure, which releases the space in the center part of the speaker, so that the circular speaker can be applied to other sound units, thereby reducing the overall volume of the speaker, and achieving the goal of improving the sound quality while reducing the increase in the volume of the speaker.

[0023] Furthermore, the diaphragm includes an outer fold ring and an inner fold ring; a flat portion is formed between the outer fold ring and the inner fold ring; a side of the outer fold ring away from the inner fold ring is connected to the support assembly; a side of the inner fold ring away from the outer fold ring is connected to the support assembly; and the dome is arranged on the flat portion.

[0024] It can be seen from the above description that by arranging an outer fold ring and an inner fold ring on the diaphragm and arranging the dome on the flat portion between the outer fold ring and the inner fold ring, the stability of the dome is improved.

[0025] Furthermore, the outer fold ring and the inner fold ring are symmetrical about the central axis of the diaphragm cross section; the dome and the voice coil are arranged on the central axis.

[0026] From the above description, it can be seen that by arranging the voice coil and the dome on the central axis of the dome, and the outer fold ring and the inner fold ring are symmetrical about the central axis of the diaphragm, the voice coil, the dome, the outer fold ring and the inner fold ring can produce more effective vibration.

[0027] Furthermore, the support assembly includes a basin frame and a magnetic component; one end of the basin frame is connected to an end of the diaphragm away from the dome; and the other end of the basin frame is connected to the magnetic component.

[0028] From the above description, it can be seen that the integrated design of the basin frame and magnetic parts can not only play a supporting role, but also a magnetic conductive role, thereby reducing material usage and optimizing costs.

[0029] Furthermore, the basin frame includes an inner ring bracket and an outer ring bracket which are symmetrically arranged about the central axis of the diaphragm; the magnetic part includes an outer ring magnet and an inner ring magnet which are symmetrically arranged about the central axis of the diaphragm; gaps are provided between the inner ring bracket and the outer ring bracket and between the outer ring magnet and the inner ring magnet to form the recessed end; one end of the outer ring bracket is connected to the end of the diaphragm away from the spherical top, and the other end of the outer ring bracket is connected to the outer ring magnet; one end of the inner ring bracket is connected to the end of the diaphragm away from the spherical top, and the other end of the inner ring bracket is connected to the inner ring magnet.

[0030] It can be seen from the above description that by providing symmetrical inner ring brackets and outer ring brackets and outer ring magnetic steels and inner ring magnetic steels, a dual magnetic structure is formed while an avoidance space is formed, making the structure more compact.

[0031] Furthermore, the cross-sections of the inner ring bracket and the outer ring bracket are L-shaped, including a vertical end and a planar end; the vertical end is connected to the diaphragm, and the planar end is connected to the magnetic member.

[0032] From the above description, it can be seen that by setting the inner ring bracket and the outer ring bracket to be L-shaped and connecting the vertical end to the diaphragm, the combined area between the bracket and the diaphragm is reduced, so that the diaphragm has a larger vibration area, thereby improving the speaker performance.

[0033] Furthermore, the support assembly also includes a base; the base is arranged on a side of the magnetic member away from the basin frame.

[0034] It can be seen from the above description that by providing a base at the bottom of the magnetic part, the base can protect the magnetic part and the internal structure, and the base is easier to install.

[0035] Furthermore, a defective portion is provided on a side of the base away from the magnetic component; a welding pad is provided in the defective portion.

[0036] It can be seen from the above description that by arranging the soldering pad on the base, the circuit connection of the speaker is realized by utilizing the soldering pad.

[0037] The circular speaker provided by the utility model can be applied to earphones, speakers and other scenes, and is described below through specific implementation methods:
