[0022] 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.

[0023] In order to achieve a better experience in the related art, it is usually necessary to put multiple speakers in a sound box, for example, respectively set a woofer, a midrange unit and a tweeter, and then filter out the redundant frequency bands through a filter to retain the desired effective bandwidth. However, although this method can improve the sound quality, it increases the volume and cost of the sound. To solve the above problems, the present application provides a speaker with a large radiation area, as follows:

[0024] Please refer to Figure 1 A loudspeaker with a large radiation area comprises a dome, two groups of diaphragms and a supporting assembly; the folding ring parts of the two groups of diaphragms are arranged opposite to each other, and the folding ring parts of the diaphragms are arranged between the dome and the supporting assembly; one end of each group of diaphragms is connected to the dome, and the other end is connected to the supporting assembly.

[0025] From the above description, it can be seen that the beneficial effects of the utility model are: a double diaphragm structure is used to support the dome, and the folding ring part of the diaphragm is arranged between the dome and the supporting assembly, so that the folding ring part of the diaphragm and the dome are not on the same plane, that is, the dome can occupy the top space alone. Compared with the technical solution in the prior art that the dome and the folding ring of the diaphragm are arranged on the same plane, the dome can be maximized. The design increases the loudness of the speaker without changing the original volume of the speaker.

[0026] Furthermore, it also includes a voice coil; the voice coil is arranged between the two groups of diaphragms; the voice coil is connected to a side of the dome close to the diaphragm.

[0027] It can be seen from the above description that by arranging the voice coil between the two groups of diaphragms and connecting the voice coil to the dome, no additional space is occupied, making the structure more compact.

[0028] Furthermore, the voice coil is arranged on the central axis of the dome; and the two groups of diaphragms are symmetrical about the voice coil.

[0029] It can be seen from the above description that by arranging the voice coil on the central axis of the dome and arranging the two groups of diaphragms symmetrically about the voice coil, the vibration of the voice coil can be effectively transmitted to the diaphragms on both sides.

[0030] Furthermore, the height of the voice coil is greater than the height of the folding ring portion of the diaphragm; and the support assembly is provided with an escape space for accommodating the voice coil.

[0031] It can be seen from the above description that by providing an avoidance space in the supporting assembly, the voice coil has enough space to vibrate, thereby improving the sound effect.

[0032] Furthermore, the support assembly includes a bracket and a magnet; one end of the bracket is connected to an end of the diaphragm away from the dome; and the other end of the bracket is connected to the magnet.

[0033] From the above description, it can be seen that the integrated design of the bracket and the magnetic steel can play both a supporting role and a magnetic conductive role, thereby reducing material usage and optimizing costs.

[0034] Furthermore, the bracket includes two groups of sub-brackets, and the magnetic steel includes two groups of sub-magnets; the two groups of sub-brackets and the two groups of sub-magnets are symmetrically arranged about the central axis of the spherical top; an avoidance space is formed between the two groups of sub-brackets and between the two groups of sub-magnets; one end of each group of sub-brackets is connected to one end of a group of diaphragms away from the spherical top, and the other end of the sub-bracket is connected to a group of sub-magnets.

[0035] It can be seen from the above description that by providing two groups of sub-magnets to form a dual magnetic structure, an avoidance space is also formed, making the structure more compact.

[0036] Furthermore, the support assembly also includes a base; the base is arranged on a side of the magnetic steel away from the bracket.

[0037] It can be seen from the above description that by providing a base at the bottom of the magnetic steel, the base can protect the magnetic steel and the internal structure, and the base makes installation easier.

[0038] Furthermore, a defective portion is provided on a side of the base away from the magnetic steel; a welding pad is provided in the defective portion.

[0039] 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.

[0040] Furthermore, the height of the diaphragm is the same as the height of the dome.

[0041] It can be seen from the above description that by setting the height of the diaphragm to be the same as the height of the dome, the top structure is made flatter.

[0042] Furthermore, the dome, diaphragm and supporting assembly are all annular.

[0043] From the above description, it can be seen that the use of an annular closed ring structure releases the space in the middle of the speaker, so that it can be applied to other sound units for additional use.

[0044] The utility model provides a loudspeaker with a large radiation area, which can be applied to earphones, speakers and other scenes, and is described below through specific implementation methods:
