[0001] The utility model relates to a hybrid speaker. Background Art

[0002] At present, as the design of mobile phone space becomes more and more compact, higher and higher requirements are placed on the space design of some products. For some products, the demand for applying some two-in-one or three-in-one designs to improve space utilization is becoming more and more urgent. At present, on most mobile phones, the speakers and motors are still designed separately. Utility Model Content

[0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned traditional technology and provide a hybrid speaker.

[0004] The purpose of the utility model is achieved through the following technical measures: a hybrid speaker, including a basin frame, a magnetic cover is provided on the basin frame, and its characteristics are: a square depression is extended to one side from the middle of the magnetic cover, a through hole is provided in the square depression, a T-shaped magnetic steel is placed in the square depression and passes through the through hole, a motor is provided on the side of the magnetic cover away from the square depression, and a tweeter and a woofer are provided on the other side of the magnetic cover.

[0005] As an improvement, the T-shaped magnetic steel includes a first magnetic steel body, a second magnetic steel body extending from the first magnetic steel body, the first magnetic steel body is located inside the square recess, and the second magnetic steel body extends through the through hole.

[0006] As a further improvement, the motor includes a motor centering support plate arranged on the magnetic cover and on a side away from the square recess, a motor vibration plate arranged on the motor centering support plate, and a counterweight magnet and a motor voice coil are provided on the side of the motor vibration plate facing the motor centering support plate; an internal magnetic gap is provided between the first magnetic steel body and the counterweight magnet.

[0007] As a further improvement, the tweeter includes a diaphragm, a tweeter dome is provided on the diaphragm, a tweeter coil is provided on the tweeter dome, a split magnet is provided on the outer periphery of the tweeter coil, and the split magnet is arranged on the magnetic cover, and the second magnet body and the tweeter coil form an internal magnetic gap of the tweeter.

[0008] As a further improvement, the woofer includes a bass centering support arranged on the basin frame, and a bass side magnet is provided on the bass centering support. The woofer also includes a bass dome arranged on the same diaphragm as the tweeter dome, and the bass dome is located on the outside of the tweeter dome. A bass voice coil is provided on the bass dome, and the bass voice coil is located on the outer periphery of the split magnet. The split magnet and the bass voice coil form an internal magnetic gap of the woofer.

[0009] As a further improvement, the tweeter dome is an aluminum-magnesium alloy tweeter dome.

[0010] As a further improvement, the bass dome is a foamed aluminum bass dome.

[0011] Due to the adoption of the above technical solution, compared with the prior art, the advantages of the present invention are:

[0012] First: The arrangement of the magnetic cover of the novel invention increases the thickness of the T-shaped magnetic steel while increasing the height of the product only slightly, effectively reducing the height of the product, increasing the utilization rate of the height of the entire machine, and saving the space of the entire machine;

[0013] Second: The new counterweight magnet replaces the original stainless steel counterweight, which can increase the momentum of the product during vibration and form a relative magnetic field with the shared T-shaped magnet. When the product is not powered, the T-shaped magnet and the counterweight magnet repel each other. When the motor voice coil is energized, the magnetic field force of the counterweight magnet changes, and the motor voice coil and the T-shaped magnet attract each other, providing a two-way attractive force to the motor, giving the motor a larger amplitude and vibration experience.

[0014] Third: The split magnet of the present invention can play two roles. First, it can split the vibration of the tweeter and the woofer, so that the two vibration systems of the tweeter and the woofer can vibrate without interfering with each other. The tweeter and the woofer can vibrate simultaneously or separately. Second, it can provide a magnetic field for the tweeter and the woofer at the same time. The split magnet and the woofer voice coil form an internal magnetic gap of the woofer, and the split magnet and the tweeter voice coil form an external magnetic gap of the tweeter, so that the performance of the tweeter and the woofer are improved at the same time.

[0015] Fourth: The tweeter dome and the woofer dome of this new model are glued to the same diaphragm, but are made of different materials. The woofer dome is made of foamed aluminum, which can provide low-frequency performance, and the tweeter dome is made of aluminum-magnesium alloy dome, which increases the stiffness of the dome and ensures the high-frequency performance of the product. The tweeter vibration system and the bass vibration system can be assembled synchronously, reducing the difficulty of assembly.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0025] Example 1: As shown in the attached Figure 1 -Attached Figure 4 As shown, a hybrid speaker includes a basin frame 1, a magnetic cover 2 is provided on the basin frame 1, a square recess 21 is extended to one side from the middle of the magnetic cover 2, a through hole 22 is provided at the square recess 21, a T-shaped magnet 3 is placed at the square recess 21 and passes through the through hole 22, a motor 4 is provided on the side of the magnetic cover 2 away from the square recess 21, and a tweeter 5 and a woofer 6 are provided on the other side of the magnetic cover 2.

[0026] The T-shaped magnetic steel 3 includes a first magnetic steel body 31 , on which a second magnetic steel body 32 extends. The first magnetic steel body 31 is located inside the square recess 21 , and the second magnetic steel body 32 extends through the through hole 22 .

[0027] The arrangement of the magnetic cover 2 increases the thickness of the T-shaped magnetic steel 3 while increasing the height of the product only slightly, thereby effectively reducing the height of the product, increasing the utilization rate of the height of the entire machine, and saving the space of the entire machine.

[0028] The motor 4 includes a motor centering support plate 41 arranged on the magnetic cover 2 and on a side away from the square recess 21, a motor vibration plate 42 arranged on the motor centering support plate 41, and a counterweight magnet 43 and a motor voice coil 44 are provided on the side of the motor vibration plate 42 facing the motor centering support plate 41; an internal magnetic gap is provided between the first magnetic steel body 31 and the counterweight magnet 43, and a protective cover 45 of the motor protection part is provided on one side of the motor vibration plate 42.

[0029] The setting of the counterweight magnet 43 replaces the original stainless steel counterweight block, which can increase the momentum of the product during vibration and form a relative magnetic field with the shared T-shaped magnet 3. When the product is not powered, the T-shaped magnet 3 and the counterweight magnet 43 repel each other. When the motor voice coil 44 is energized, the magnetic field force of the counterweight magnet 43 is changed, and the motor voice coil 44 and the T-shaped magnet 3 attract each other, providing a two-way attractive force to the motor 4, so that the motor 4 has a larger amplitude and vibration experience.

[0030] The tweeter 5 includes a diaphragm 7, a tweeter dome 51 is provided on the diaphragm 7, a tweeter voice coil 52 is provided on the tweeter dome 51, a split magnet 8 is provided on the outer periphery of the tweeter voice coil 52, and the split magnet 8 is arranged on the magnetic cover 2, and the second magnet body 32 and the tweeter voice coil 52 form an internal magnetic gap of the tweeter 5.

[0031] The woofer 6 includes a bass centering support 61 arranged on the basin frame 1, and a bass side magnet 62 is provided on the bass centering support 61. The woofer 6 also includes a bass dome 63 arranged on the same diaphragm 7 as the tweeter dome 51, and the bass dome 63 is located on the outside of the tweeter dome 51. A bass voice coil 64 is provided on the bass dome 63, and the bass voice coil 64 is located on the outer periphery of the split magnet 8. The split magnet 8 and the bass voice coil 64 form an internal magnetic gap of the woofer 6.

[0032] The split magnet 8 can play two roles. First, it can split the vibration of the tweeter 5 and the woofer 6 so that the two vibration systems of the tweeter 5 and the woofer 6 do not interfere with each other. The tweeter 5 and the woofer 6 can vibrate at the same time or separately. Second, it can provide a magnetic field for the tweeter 5 and the woofer 6 at the same time. The split magnet 8 and the woofer voice coil 64 form an internal magnetic gap of the woofer 6, and the split magnet 8 and the tweeter voice coil 52 form an external magnetic gap of the tweeter 5, so that the performance of the tweeter 5 and the woofer 6 are improved at the same time.

[0033] Traditional dynamic speakers have only one voice coil, making it difficult to achieve both high and low frequency performance. To achieve good low-frequency performance, the product's F0 needs to be reduced, the product's vibration mass needs to be increased, and the voice coil design needs to be heavier. However, a heavier voice coil design will lead to a decrease in the product's mid- and high-frequency performance, as well as poor high-frequency transient response. To achieve good high-frequency performance, the resonant frequency needs to be increased, and the voice coil needs to be lighter. Currently, traditional dynamic speakers struggle to achieve both, and can only choose a balance. This new design divides the voice coil into the woofer voice coil 64 and the tweeter voice coil 52. The outer woofer voice coil 64 is made of heavier copper wire, which improves low-frequency performance. The inner tweeter voice coil 52 is made of lighter copper-clad aluminum wire, which improves high-frequency performance. This solves the problem of traditional speakers being unable to achieve both due to having only one voice coil.

[0034] The tweeter dome 51 is an aluminum-magnesium alloy tweeter dome 51, which increases the dome stiffness, reduces the vibration mass, and ensures the high-frequency performance of the product; the bass dome 63 is a foamed aluminum bass dome 63, which can provide low-frequency performance; and the problem that traditional speaker domes cannot take into account both high and low frequency performance is solved simultaneously. The tweeter vibration system and the bass vibration system can be assembled simultaneously, reducing the difficulty of assembly.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
