Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coaxial loudspeakers, in particular to a coaxial loudspeaker with a new structure. Background Art
[0002] As we all know, coaxial speakers are widely used in practical applications. Their structure is more complicated than that of dynamic cone speakers. If we distinguish them by the installation method of high-frequency speakers, they are generally divided into installation based on the center column of the low-frequency speaker and installation based on the surface of the low-frequency speaker. Installation based on the center column of the low-frequency speaker limits the structure of the high-frequency speaker and requires compromises in size and performance. Installation based on the surface of the low-frequency speaker limits the design of the low-frequency speaker. At the same time, the installation components will produce excess sidelobe radiation and phase errors due to the diffraction of sound. In particular, the phase plug is a key component that affects the sound wave radiation characteristics. Its size and shape are directly related to the direct directivity and sidelobe control of the sound. Once determined in the traditional design, it is not easy to adjust, which may cause phase distortion and unnecessary sound wave interference, affecting the sound quality. Therefore, it is necessary to propose a solution to this technical problem. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.
[0019] See also Figure 1-2The utility model is a coaxial loudspeaker of a novel structure, comprising a basin frame 1, one end of which is provided with a washer 2, a magnetic steel 3 and a T iron 4 in sequence, the inner wall of the basin frame 1 is provided with a cone 5, the cone 5 is provided with a dust cap 6, one end of the cone 5 is provided with a spring 7 and a voice coil 8, the other end of the basin frame 1 is provided with a mounting frame 9, the mounting frame 9 is provided with an opening, the mounting frame 9 is provided with a curved panel 10, a phase plug 11 is provided between the curved panel 10 and the opening, and a phase plug 11 is provided between the curved panel 10 and the mounting frame 9. There is a mounting mechanism. In this embodiment, the mounting mechanism can be used to assemble the curved panel 10, which is convenient for replacing the phase plug 11, so as to adapt to cones 5 of different depths and curvatures and dust caps 6 of different shapes, eliminate excess side lobe radiation, reduce phase errors, greatly reduce the design limitations of the coaxial speaker, improve the performance of the coaxial speaker, and broaden its scope of application in different audio application scenarios. The washer 2, magnetic steel 3, T-iron 4, cone 5, elastic wave 7 and voice coil 8 are components required for traditional speakers and are not described in detail in this structure.
[0020] In this solution, the mounting mechanism includes a threaded groove, which is provided on the mounting frame 9 , and the curved panel 10 is threadedly connected to the threaded groove. The curved panel 10 is threadedly connected to the threaded groove, so that the curved panel 10 can be easily disassembled.

This balance contributes to the clarity and dynamic performance of the mid- and low-frequency bands.
[0022] In this solution, based on the method of installing a high-frequency speaker on the surface of a low-frequency speaker to form a coaxial speaker, a phase plug of the low-frequency speaker is added to the high-frequency speaker mounting assembly and designed as a replaceable module, which can be well adapted to cones of different depths and curvatures and dust caps of different shapes. Excess side lobe radiation is removed and phase errors are reduced. The design limitations of the coaxial speaker are greatly reduced and the performance of the coaxial speaker is improved.
