Description
Technical Field
The invention relates to the technical field of electroacoustic transducers, in particular to an electroacoustic transducer with a diaphragm.
Background
An acoustic transducer is a device that converts electrical energy into acoustic energy, also commonly referred to as a speaker or horn. The conventional electroacoustic transducer generally includes a frame, a magnetic circuit system installed in the frame, a voice coil movably accommodated in the magnetic circuit system, and a diaphragm installed on the frame, wherein the voice coil is connected with the diaphragm to drive the diaphragm to vibrate, thereby generating sound.
However, the conventional electroacoustic transducer is directly connected to the bottom of the diaphragm entirely by the voice coil, and therefore, an ineffective portion of the voice coil higher than the outside of the magnetic circuit system consumes not only the magnetic flux but also the weight of the voice coil is emphasized, which ultimately affects the efficiency of the voice coil and the sound effect of the electroacoustic transducer.
Disclosure of Invention
The invention aims to solve the technical problem that the height of the limiting block can be adjusted through the height adjusting mechanism, so that the installation space in the frame is adjusted, vibrating diaphragms with different thicknesses can be installed in the upper end of the frame, and the effect of increasing the practical performance is achieved; an electroacoustic transducer having a diaphragm is provided.
To solve the technical problems, the structure of the invention comprises
The frame is provided with a plurality of grooves,
a vibrating diaphragm, the vibrating diaphragm is arranged in the upper end of the frame,
the voice coil is connected to the bottom of the vibrating diaphragm,
the magnetic circuit system is sleeved with a mounting frame, the magnetic circuit system is detachably connected in the lower end of the frame through the mounting frame, the magnetic circuit system is enclosed to form an annular air gap, the vibrating diaphragm is opposite to the magnetic circuit system, the voice coil is movably accommodated in the annular air gap of the magnetic circuit system,
the upper cover, upper cover detachably connect the top at the frame, the bottom of upper cover be provided with the stopper, the stopper pass through the bottom of high adjustment mechanism connection upper cover.
Further: the vibrating diaphragm include vibrating portion and connect in the laminating portion of vibrating portion week side, laminating portion laminating is fixed in on the periphery of frame, vibrating portion just to magnetic circuit, the stopper be located the laminating portion directly over.
Still further: the inner side wall of the lower end of the frame is provided with a groove, the mounting frame is provided with a hemispherical clamping groove corresponding to the position of the groove, the groove is internally connected with a spherical clamping head through a spring, and the spherical clamping head is clamped into the hemispherical clamping groove under the action of the spring.
Still further: the height adjusting mechanism comprises an adjusting bolt and a threaded through hole formed in the upper cover, and the adjusting bolt penetrates through the threaded through hole and is connected with the limiting block.
After the structure is adopted, the height of the limiting block can be adjusted through the height adjusting mechanism, so that the installation space in the frame is adjusted, vibrating diaphragms with different thicknesses can be installed in the upper end of the frame, and the effect of increasing the practical performance is achieved; the design has the advantages of simple structure, easy manufacture, practicality and high efficiency.
