The 10-inch 40-ounce magnet midrange speaker is the mid-range speaker unit in the car speaker. Its function is to reproduce the intermediate frequency signal (frequency range is generally 150Hz-5KHz) output from the frequency divider.
In general, a 10-inch, 40-ounce magnet midrange speaker has a frequency response curve that is flat, and the effective frequency response range is greater than the width of the sounding band it is responsible for in the system. The impedance is consistent with the sensitivity and low frequency unit. Sometimes the midrange has insufficient power capacity, and the sensitivity is higher, and the impedance is higher than the midrange unit of the woofer, thereby reducing the actual input power of the midrange unit.
The 10-inch, 40-ounce magnet midrange speaker typically has a cone and a dome. It is only larger in size and power than the tweeter and is suitable for playing mid-range audio. The diaphragm of the midrange unit is mainly composed of soft materials such as paper cones and enamel membranes, and occasionally a small amount of alloy dome diaphragms.
The winding of the voice coil 105 of a 10-inch 40-ounce magnet midrange speaker is (by winding the voice coil wire around the voice coil bobbin, or by winding the voice coil wire around the two sides of the voice coil bobbin, first The segment line width is wound, and after a certain interval, the second line width is re-wound; the magnetic circuit system uses a plurality of magnets 104 to sandwich a clamping plate 103, wherein the diameter of the clamping plate 103 is large, and the diameter of the magnetic steel 104 small. This structure makes the 10-inch 40-ounce magnet midrange speaker only use speakers with a diameter of 20cm and 20cm to ensure that the speaker has a wide mid-range section, which results in the acceptance of a 10-inch 40-ounce magnet midrange speaker. The power is not high, so the three-way 10-inch 40-ounce magnet midrange speaker can't improve the overall power because the power of the 10-inch 40-ounce magnet midrange speaker is not enough; at the same time, the low frequency of the 10-inch 40-ounce magnet midrange speaker of this caliber The bandwidth of the part is too large, and the low frequency part is required to be filtered when the frequency divider is made, thereby increasing the manufacturing cost of the frequency divider and directly increasing the manufacturing cost and the use cost of the speaker.
SUMMARY OF THE INVENTION The technical problem to be solved by the present invention is to overcome the above-mentioned shortcomings of the prior art, and to provide an overall power with a large withstand power to increase the three-way 10 inch 40 ounce magnet midrange speaker, and has better The mid-audio width is a 10-inch, 40-ounce magnet midrange speaker that reduces the cost of the divider while providing distortion and sensitivity. The technical solution of the present invention is to provide a 10-inch 40 ounce magnet midrange speaker having the following structure, including a magnetic steel, a voice coil, a splint and a back cover, the magnetic steel and the splint being located in the voice coil. The voice coil of the two voice widths of the voice coil is wound on the voice coil bobbin in a positive winding manner, and a distance is left between the two line widths; the magnetic steel package is sandwiched between the two splints. As an improvement, the two line widths of the voice coil may be wider than the thickness of the splint; the distance between the two line widths may be slightly smaller than the thickness of the magnetic steel; the back cover may be made of aluminum material. The back cover; the speaker can have a diameter of 38 cm or more. After adopting the above structure, the 10-inch 40-ounce magnet mid-range speaker of the utility model can achieve a diameter of 38 cm or more, which not only filters out the low frequency and high frequency bandwidth, but also achieves an ideal condition of the intermediate frequency bandwidth, and 10 inches of 38 cm or more. The 40-ounce magnet midrange speaker is more than three times more powerful than the 20-inch or lower 10-inch 40-ounce magnet midrange speaker, which solves the problem of power-up of the three-way 10-inch 40-ounce magnet midrange speaker; Part of the structural design reduces the manufacturing cost and operating cost of the speaker; it also reduces the nonlinear distortion and transient distortion of the speaker, improving the efficiency and sensitivity of the speaker.

Detailed ways
The 10-inch 40-ounce magnet midrange speaker of the present invention comprises a vibrating plate 7, a U-iron 2, a hammer 5, a magnetic steel 4, a splint 3, a basin frame 6, and a rear cover 1. Both the magnetic steel 4 and the cleat 3 are located inside the voice coil 5. The splint 103 has a large diameter and the magnetic steel 104 has a small diameter. The above is prior art. The utility model is characterized in that the voice coil 5 of the voice coil 5 is wound around the voice coil bobbin in a positive winding manner, and a distance is left between the two line widths, the voice coil The two line widths (sizes) of 5 are both wider than the thickness (size) of the splint 3, that is, the line width (size) of each segment is wider than the thickness (size) of each of the splints 3. The magnetic steel 4 is sandwiched between two plywoods 3. The distance (size) between the two line widths is slightly smaller than the thickness (size) of the magnetic steel 4. The magnetic steel 4 is two pieces, and the distance between the two line widths is slightly smaller than the thickness of the magnetic steel 4, and the distance between the two line widths is slightly smaller than the thickness of the two magnetic steels 4.
