The microphone core and the loudspeaker are two terminals of an electroacoustic device. The microphone is the input, and the loudspeaker is the output. The microphone is also known as a microphone, a microphone, and a microphone. The existing microphone core is usually fixed and installed between the shell and the inner mounting seat for placing the sound pickup head by screws during use, which is troublesome to operate. Therefore, a new type of microphone core is proposed. At present, most of the microphone cores on the market have the following disadvantages: most of them use glue to bond the upper cover plate, which is not convenient for assembly, thereby affecting the production efficiency of the microphone core. In summary, most of the existing new microphone cores still cannot meet the actual needs.

[0003] In view of the above problems, the prior art (publication number CN212013046U) discloses a moving coil type microphone core and microphone, which comprises: a shell, a first cavity is arranged in the shell, a diaphragm and a magnet are sequentially arranged in the first cavity, an acoustic chamber is connected to one end of the shell close to the magnet, the acoustic chamber is provided with a second cavity with an upward opening, and the opening of the second cavity is communicated with the first cavity; the sound head pad comprises an outer ring body and an inner ring body, the outer ring body and the inner ring body are connected by a plurality of soft body bars arranged at intervals, the acoustic chamber is arranged in the inner ring body, and the acoustic chamber is connected with the inner ring body. The inner ring body and the outer ring body of the sound head pad are connected by a plurality of soft body bars arranged at intervals.

[0004] However, the above microphone core shell is uniformly distributed by a single bar, and the effect of improving high pitch is not enough during use, so that the above microphone core has defects during use. UTILITY MODEL CONTENTS

[0005] The technical problem solved by the utility model is to provide a microphone core shell structure for improving high pitch, which can solve the problem of insufficient effect of improving high pitch during use.

[0006] TECHNICAL SCHEME: In order to solve the above technical problems, according to one aspect of the utility model, more specifically, a microphone core shell structure for improving high pitch is provided, which comprises a shell, a microphone core inner sleeve is arranged in the shell, a microphone core magnetic circuit is clamped in the inner sleeve, four through grooves are uniformly arranged on the inner wall of the shell, four groups of inner bars are integrally formed on the inner wall of the shell, and a through hole is arranged below the through groove on the outer wall of the shell.

[0007] Furthermore, the number of inner bars in each group is three.

[0008] Further, the inner rib is away from the surface of the inner wall of the outer shell and is attached to the outer wall of the inner sleeve of the microphone.

[0009] Further, the inner diameter of the inner sleeve of the microphone is suitable for assembling the magnetic circuit of the microphone.

[0010] Further, each of the through grooves is located between two groups of adjacent inner ribs.

[0011] Beneficial effects: through the assembly of the outer shell and the inner sleeve of the microphone by four groups of inner ribs and the attachment of the outer wall of the inner sleeve, the installation and disassembly between the outer shell and the inner sleeve of the microphone are more convenient and efficient, thereby saving the time of installation and disassembly and improving the efficiency, and through the structural feature that each group of three inner ribs forms a cavity with the outer wall of the inner sleeve of the microphone and cooperates with four through grooves and four through holes, the distribution of the space in each direction is changed, the space of bass, medium and high pitch can be effectively adjusted and distributed more reasonably, the connection and performance of bass, medium and high pitch are more hierarchical and smooth and clear, thereby improving the effect of the microphone in use, and the magnetic circuit of the microphone is installed to the outer shell of the microphone through the inner sleeve, so that the installation of the magnetic circuit of the microphone is more convenient and efficient.
