Related Art

In the current market, a driver applied to a speaker is generally composed of a single woofer or a combination of a woofer and a tweeter. The type of the woofer is typically a dynamic coil type, and the type of the tweeter is a dynamic coil type or a balanced armature type, and both the structures of the woofer and the tweeter are independent structures. Because there is no midrange driver to balance the sound of the tweeter and the woofer, the absence of the midrange driver leads to the more monotonous sound of the speaker and fails to meet the midrange tone and thus, the fullness of the tone of the speaker is insufficient. Simultaneously, because the independent structure of the woofer and the tweeter results in the difficulty of mounting the speaker and so on and fails to meet the coaxial configuration of the woofer, the midrange driver and the tweeter, the sound of the speaker is unbalanced on the low frequency range, the midrange and the high frequency range and it causes the terrible listening experience.

So the magnetic guiding effect of the magnetic guiding ring 134 enhances the strength of the magnetic field of the second magnetic circuit module 13.

Please refer to FIG. 3 to FIG. 5 again, in this embodiment, the first bracket 141, the second bracket 151 and the third bracket 161 are all circle brackets which serve as the bracket bodies for mounting the first diaphragm 142, the second diaphragm 152 and the third diaphragm 162. The first bracket 141 and the second bracket 151 are respectively disposed on the different two sides of the magnetic flux guiding plate 11, and the third bracket 161 is disposed on the outer sides of the first bracket 141 and the second bracket 151. The first bracket 141, the second bracket 151 and the third bracket 161 are arranged corresponding to the central axial line 110 of the magnetic flux guiding plate 11.

The first bracket 141 is positioned outside the first auxiliary magnet 122 of the first magnetic circuit module 12, one end of the first bracket 141 extends upward and inward, and the inner face on the end of the first bracket 141 is fixed above the first auxiliary magnet 122 and the first auxiliary magnetic guiding plate 124. The first diaphragm 142 is a disc shape structure, the peripheral side of the first diaphragm 142 is fixed on the outer side of one end of the first bracket 141, wherein the first bracket 141 may be made of metal or plastic material, and the inner side of the first bracket 141 is fixed above the first auxiliary magnet 122 and the first auxiliary magnetic guiding plate 124 by laser welding or glue attachment.

The second bracket 151 is disposed on the outer side of the second auxiliary magnet 132, the inner face of one end of the second bracket 151 is positioned underneath the second auxiliary magnet 132, the second diaphragm 152 is a disc shape structure, and the peripheral side of the second diaphragm 152 is fixed on the outer side of one end of the second bracket 151. The other end of the second bracket 151 extends outward and upward to be a right angle, wherein the second bracket 151 is a yoke made of the magnetic guiding material, so that the magnetic guiding effect of the second bracket 151 enhances the strength of the magnetic field of the second auxiliary magnet 132 of the second magnetic circuit module 13.

One end of the third bracket 161 is positioned outside the other end of the second bracket 151, wherein the third bracket 161 is configured with a glue groove 1611, the glue groove 1611 of the third bracket 161 is filled with the glue 1610 to attach the third bracket 161 to the second bracket 151 so that the second bracket 151 is fixed to and connected to the third bracket 161. The other end of the third bracket 161 extends outward and upward, and the other end of the third bracket 161 extends upward beyond the magnetic flux guiding plate 11, wherein the third bracket 161 may be made of metal or plastic material. The third diaphragm 162 is a ring shape structure, the outer side of the third diaphragm 162 is disposed on the other end of the third bracket 161, and the inner side of the third diaphragm 162 is positioned outside of the first bracket 141.

Further, please refer to FIG. 3 and FIG. 6. To further strengthen the combined strength of the third bracket 161 and the second bracket 151, the third bracket 161 has a plurality of engaging blocks 1612 which are separately disposed, and a plurality of engaging grooves 1510 are disposed on the surrounding of the second bracket 151 in correspondence to the positions of the plurality of engaging grooves 1510, and the plurality of engaging blocks 1612 are correspondingly engaged with and connected to the plurality of engaging grooves 1510, and thus, the horizontal rotation of the combination of the third bracket 161 and the second bracket 151 is limited. In addition, the third bracket 161 further includes multiple first through holes 1613 and multiple second through holes 1614, and the multiple first through holes 1613 and the multiple second through holes 1614 connect the inner side and the outer side of the full-band dual-sided speaker device 1, and thus, it is beneficial for the air circulation between the inner and outer sides of the full-band dual-sided speaker device 1 to facilitate the full-band dual-sided speaker device 1 to generate the sound. The multiple first through holes 1613 are elongated holes, and the multiple second through holes 1614 are circular holes, and the number and the shape of the above-mentioned through holes can be adjusted according to the user's needs.

According to the above description, the first bracket 141 is disposed on the magnetic flux guiding plate 11, and one end of the first bracket 141 extends upward and inward so that the first bracket 141 is fixed to the lower side of the first diaphragm 142 and support the first diaphragm 142. The other end of the third bracket 161 extends outward and upward. When the other end of the third bracket 161 extends upward beyond the magnetic flux guiding plate 11, but does not exceed the highest point of the first bracket 141, the third bracket 161 is fixed to the lower side of the third diaphragm 162 and supports the third diaphragm 162. The vertical height of the third diaphragm 162 relative to the magnetic flux guiding plate 11 is lower compared to the vertical height of the first diaphragm 142 relative to the magnetic flux guiding plate 11. In other words, by dislocations that the first diaphragm 142 and the third diaphragm 162 are not located on the same plane, the first diaphragm 142 and the third diaphragm 162 exhibit a stepped structure with height differences, and thus, the resonance state of the first diaphragm 142 and the third diaphragm 162 on the same plane may not affect the vibration amplitude and the vibration frequency of the sounds generated by the first diaphragm 142 and the third diaphragm 162.

In this embodiment, when the first vibration assembly 14 in conjunction with the first magnetic circuit module 12 generates sound through vibration, the vibration frequency of the first diaphragm 142 is higher and the amplitude variation of the first diaphragm 142 is smaller and the first diaphragm 142 is suitable for the high-frequency range with the high frequency because the area of the first diaphragm 142 of the first vibration assembly 14 is relatively smaller than the area of the second diaphragm 152 and the third diaphragm 162. When the second vibration assembly 15 in conjunction with the second magnetic circuit module 13 generates sound through vibration, the vibration frequency of the second diaphragm 152 is medium and the amplitude variation of the second diaphragm 152 is medium and the second diaphragm 152 is suitable for the midrange with the medium frequency because the area of the second diaphragm 152 of the second vibration assembly 15 is between the area of the first diaphragm 142 and the area of the third diaphragm 162. When third vibration assembly 16 in conjunction with the second auxiliary magnet 132 of the second magnetic circuit module 13 generates sound through vibration, the vibration frequency of the third diaphragm 162 is lower and the amplitude variation of the third diaphragm 162 is larger and the third diaphragm 162 is suitable for the low-frequency range with the low frequency because the area of the third diaphragm 162 of the third vibration assembly 16 is relatively larger than the area of the first diaphragm 142 and the area of the second diaphragm 152. The diaphragm with larger areas as mentioned above is less sensitive to the vibration variation of the high-frequency, so the diaphragm with smaller areas is more suitable for the high frequency. As a result, the first vibration assembly 14 is configured to produce sound in the high-frequency range by the vibration, the second vibration assembly 15 is configured to produce sound in the mid-frequency range by the vibration, and the third vibration assembly 16 is configured to produce sound in the low-frequency range by the vibration.

In this embodiment, when the first voice coil 143 is conducted by electricity to generate a magnetic field and the strength and the direction of the magnetic field can be changed by currents and the first voice coil 143 undergoes the magnetic field of the first main magnet 121 and the first auxiliary magnet 122 of the first magnetic circuit module 12, the vibration of the first voice coil 143 changes and drives the first diaphragm 142 to generate the sound for the high-frequency range. Furthermore, when the second voice coil 153 is conducted by electricity to generate a magnetic field and the strength and the direction of the magnetic field can be changed by currents and the second voice coil 153 undergoes the magnetic field of the second main magnet 131 and the second auxiliary magnet 132 of the second magnetic circuit module 13, the vibration of the second voice coil 153 changes and drives the second diaphragm 152 to generate the sound for the midrange. Additionally, when the third voice coil 163 is conducted by electricity to generate a magnetic field and the strength and the direction of the magnetic field can be changed by currents and the third voice coil 163 undergoes the magnetic field of the second auxiliary magnet 132 of the second magnetic circuit module 13, the vibration of the third voice coil 163 changes and drives the third diaphragm 162 to generate the sound for the low-frequency range. The aforementioned high-frequency, mid-frequency, and low-frequency sounds represent different audio frequencies when compared to each other.

As the abovementioned, the present application provides a full-bandwidth dual-sided speaker device, comprising: a magnetic flux guiding plate, a first magnetic circuit module, a second magnetic circuit module, a first vibration assembly, a second vibration assembly and a third vibration assembly. The first magnetic circuit module is disposed above the magnetic flux guiding plate, and the second magnetic circuit module is disposed under the magnetic flux guiding plate. The first vibration assembly is disposed above the first magnetic circuit module, and the second vibration assembly is disposed under the second magnetic circuit module. The third vibration assembly is disposed above the magnetic flux guiding plate, and the third vibration assembly is corresponding to above the outer side of the second magnetic circuit module. The third vibration assembly is positioned outside the first vibration assembly.
