Description

Novel sound cavity type Bluetooth headset loudspeaker Technical Field The utility model relates to the technical field of Bluetooth headset horns, in particular to a novel sound cavity type Bluetooth headset horn. Background The patent number is ZL202223009132.X, the patent name is China patent of an earphone horn for improving magnetic field strength, and the utility model specifically discloses the technical scheme that the earphone horn for improving magnetic field strength comprises a mounting frame, U-shaped iron, a voice coil, a diaphragm, a magnet and a washer, wherein the U-shaped iron, the voice coil, the diaphragm, the magnet and the washer are arranged on the mounting frame, the U-shaped iron is arranged in the middle of the mounting frame, the U-shaped iron is provided with a concave cavity with an open upper end, the magnet is arranged on the inner end surface of the concave cavity, the washer is arranged at the upper end of the magnet, the lower end of the voice coil stretches into the concave cavity, the magnet and the washer are arranged on the inner periphery of the voice coil, the diaphragm is arranged at the upper end of the mounting frame, the voice coil is arranged at the lower end of the diaphragm, the upper end of the mounting frame is provided with a mounting step, and the outer end of the diaphragm is arranged on the mounting step. The earphone horn for improving the magnetic field strength still has the defect that the earphone horn for improving the magnetic field strength does not have an independent sound cavity structure, namely does not have the function of realizing tuning through an independent sound cavity. Disclosure of utility model The utility model aims to provide a novel sound cavity type Bluetooth earphone loudspeaker aiming at the defects of the prior art, and the novel sound cavity type Bluetooth earphone loudspeaker is novel in structural design and has an independent sound cavity structure, namely tuning can be realized through an independent sound cavity. In order to achieve the above object, the present utility model is achieved by the following technical scheme. A novel sound cavity type Bluetooth earphone loudspeaker comprises a plastic bracket, a U iron, a voice coil, a diaphragm, a magnet and a washer, wherein the U iron is arranged on the plastic bracket and surrounds the periphery of the U iron, a cavity which is frontward opened is formed in the U iron, the magnet is fixedly arranged on the bottom surface of the cavity, the washer is fixedly arranged on the front end surface of the magnet, and the magnet and the washer are respectively spaced with the side wall of the cavity; The voice coil stretches into the concave cavity, and the voice coil is sleeved on the periphery of the magnet and the washer; the edge part of the diaphragm is fixedly arranged on the plastic bracket, the diaphragm is positioned at the front end side of the concave cavity, and the front end part of the voice coil is connected with the diaphragm; An independent sound cavity which is opened forward is formed on the inner side of the edge part of the diaphragm of the plastic support, the independent sound cavity is spaced from the U-shaped iron, and the independent sound cavity is positioned on the outer side of the U-shaped iron; The side wall of the plastic support is provided with a sound hole which is opened outwards and communicated with the independent sound cavity, and the outer end opening position of the sound hole is provided with a tuning net.
