An embodiment of the combination of a vertical plane voice coil and a conductive diaphragm; [Fig. 8] is a cross-sectional embodiment of the one shown in Fig. 7; [Fig. 9] is a cross-sectional embodiment of a vertical plane driving vibration mode suspended on a plane bracket Figure; and [Figure 10] is a frequency response comparison chart between this embodiment and a conventional speaker.

As shown in Figures 2 and 3, this embodiment is a planar speaker structure 100 with a vertical planar voice coil and a conductive diaphragm, which includes: a support frame 10; a first magnet 211; a second magnet 212; and A vertical plane drives the vibration mode 30 . For convenience of explanation, the planar speaker structure 100 with a vertical planar voice coil and a conductive diaphragm in the following embodiment will be referred to as the planar speaker structure 100 for short.

The support frame 10 is mainly used to support the vertical plane driving vibration mode 30. Therefore, the support frame 10 has a plane bracket 110, and a central opening 111 is formed in the center of the plane bracket 110; in addition, the support frame 10 can also be used to fix the first magnet. 211 and the second magnet 212, for example, a plurality of support legs 112 extend downward from the planar bracket 110, thereby effectively fixing the first magnet 211 and the second magnet 212, and providing a vertical plane to drive the vibration mode 30 to vibrate up and down. Height space required.

The first magnet 211 is a permanent magnet and is disposed on the first side below the planar bracket 110; the second magnet 212 is also a permanent magnet and is disposed on the second side below the planar bracket 110; for effective fixation Therefore, a set of upper washers 213 and a set of lower washers 214 can be used above and below the first magnet 211 and the second magnet 212 to effectively fix the first magnet 211 and the second magnet 212 . Magnet 211 and second magnet 212.

The above-mentioned upper washer 213, first magnet 211, second magnet 212, and lower washer 214 form a sandwich structure, and form an integral structure under the frame of the support frame 10. In addition, in the central part of the sandwich structure , that is, a moving gap 215 is formed between the two upper washers 213, between the first magnet 211 and the second magnet 212, and between the two lower washers 214.

As shown in Figures 4 and 5, the vertical plane driving vibration mode 30 has: at least A vertical planar voice coil 310; a conductive diaphragm 320; and a packaging film 330. At least one vertical planar voice coil 310 and the conductive diaphragm 320 are in a T-shaped structure perpendicular to each other.

As shown in Figures 4 to 6, the vertical plane voice coil 310 is equivalent to the voice coil structure of a general speaker. The vertical plane voice coil 310 is embedded in the movable gap 215. When the input to the vertical plane voice coil 310 is, for example, audio. After receiving the signal, the vertical plane voice coil 310 will generate a voice coil magnetic field as the audio signal changes, and the voice coil magnetic field will magnetically interact with the first magnet 211 and the second magnet 212, causing the vertical plane voice coil 310 to move upward. , move down.

Since the movable gap 215 only requires a tiny magnetic gap, which is usually slightly larger than the thickness of the vertical planar voice coil 310 , the vertical planar voice coil 310 can achieve higher magnetic energy conversion efficiency, and the magnetic circuit of the planar speaker structure 100 can be optimized. Stacked with the stroke, the height limit of the planar speaker structure 100 can be reduced.

Since the vertical planar voice coil 310 can be a single-layer or multi-layer structure, and because it is a planar copper wiring voice coil, it is not limited by the shape of the traditional voice coil, so it can be made more slender, narrower, and thinner... etc. The advantages.

The vertical plane voice coil 310 may be composed of a single or a plurality of vertical plane voice coils 310. For example, the vertical plane voice coil 310 may have a first vertical plane voice coil 311 and a second vertical plane voice coil 312, and the first vertical plane voice coil 310 may have a first vertical plane voice coil 311 and a second vertical plane voice coil 312. An insulating film 313 is disposed between the voice coil 311 and the second vertical plane voice coil 312 .

In addition to being composed of two vertical plane voice coils 310, the vertical plane voice coil 310 can also be composed of three, four or more vertical plane voice coils 310, and the electrical connection of the vertical plane voice coils 310 can be Electrical connection in series, parallel, or series/parallel.

The vertical planar voice coil 310 can be used in the design of standard impedance or other special impedance requirements according to the requirements of acoustic impedance value; in terms of electrical advantages, it can reduce nonlinear distortion and total harmonic distortion (THD), and can effectively avoid abnormal sound (Rub &Buzz); and in terms of temperature resistance characteristics, It can withstand high-power current; especially suitable for 1~5W power design, and is better than current micro-speaker applications.

As shown in Figures 4 and 7, the conductive diaphragm 320 has: a diaphragm 321; a first conductive sheet 322; and a second conductive sheet 323. The ends extending outward on both sides of the first conductive sheet 322 and the second conductive sheet 323 can be respectively the first sound source input end 30a and the second sound source input end 30b of the planar speaker structure 100, which can facilitate different models of products. During production, the sound source input direction is replaced.

In order to achieve mass production and avoid errors in welding operations, the first sound source input terminal 30a and the second sound source input terminal 30b can be designed at both ends of the long axis of the vertical planar voice coil 310, and are respectively located vertically. The plane voice coil 310 is on the two corresponding sides. When produced in this way, even if the vertical plane voice coil 310 is rotated 180 degrees horizontally, there will be no welding errors, and there is no need to think about the placement direction of the vertical plane voice coil 310. In the operating mode, production efficiency can be improved.

The diaphragm 321 is equivalent to the sound cone of a general speaker, and the bottom surface of the diaphragm 321 and the vertical plane voice coil 310 are linked to move up and down. That is to say, when the vertical plane voice coil 310 is connected with the first magnet 211 and the third When the two magnets 212 vibrate up and down through magnetic interaction, they will cause the diaphragm 321 to vibrate up and down, and the vibration of the diaphragm 321 will push the surrounding air to vibrate to produce sound.

The first conductive piece 322 is disposed on the first side of the diaphragm 321 and is electrically connected to the first voice coil input end 31a of the vertical planar voice coil 310, that is, the first welding portion; the second conductive piece 323 is disposed on the vibrator. The second side of the membrane 321 is electrically connected to the second voice coil input end 31b of the vertical planar voice coil 310, that is, the second welding portion.

In order to have good electrical conductivity, the first conductive sheet 322 and the second conductive sheet 323 are both copper conductive sheets. In addition, by replacing the signal leads of the conventional speakers with the conductive sheet, the signal wire of the conventional speaker can be completely replaced. Bottom improvement: When copper wires are used as signal leads, the signal leads vibrate up and down along with the sound cone for a long time, so the problem of wire breakage is likely to occur.

Between the first conductive sheet 322 and the second conductive sheet 323 and the first input end 31a and the second input end 31b of the vertical planar voice coil 310, there may be further provided a heat-resistant and insulating first welding positioning piece 32a and a second welding positioning piece 32a respectively. The welding positioning piece 32b, the first welding positioning piece 32a and the second welding positioning piece 32b respectively have a pair of welding openings 33.

Through the welding opening 33, the welding between the first conductive piece 322 and the first input terminal 31a and the second conductive piece 323 and the second input terminal 31b can be performed only at the welding opening 33, thus avoiding large-scale welding. , or excessive solder 33a is attached during soldering, which affects the weight, balance and frequency response of the diaphragm 321.

The first conductive sheet 322 and the second conductive sheet 323 respectively have a set of arc-shaped bending parts 324, and an extending plane 325 is provided at the end of each arc-shaped bending part 324. Through the curve of the arc-shaped bending portion 324, the first conductive sheet 322 and the second conductive sheet 323 can have the same curvature as the suspension portion 332, so they can be perfectly integrated into one body, and the extending plane 325 can be used as the third conductive sheet 322. A welding portion where a conductive piece 322 and a second conductive piece 323 are welded to the first input terminal 31a and the second input terminal 31b.

In addition, in order to avoid the stress of the arc-shaped bending part 324 and the extended plane 325 from causing interference to the suspension part 332 when it vibrates up and down, thereby affecting the compliance restoring force and damping effect of the suspension part 332, so in the arc-shaped bending A plurality of through holes 326 may be provided on the extending plane 325 at the end of the arc-shaped bending part 324 and/or the arc-shaped bending part 324, thereby reducing the stress on the arc-shaped bending part 324 and the extending plane 325.

As shown in Figure 8, the packaging film 330 has: a diaphragm support part 331; a suspension part 332; a conductive sheet packaging part 333; and a coil packaging part 334.

The diaphragm supporting part 331 is a plane and is closely connected with the diaphragm 321 from the bottom of the diaphragm 321 to form a single body.

The suspension portion 332 surrounds and is coupled to the outer edge of the diaphragm support portion 331, and the cross section of the suspension portion 332 can be a semicircular arc-shaped structure. The suspension part 332 is equivalent to the suspension edge of a general speaker around the sound cone. The suspension part 332 is mainly used to support the vibration system of the diaphragm 321 and provide compliance restoring force and damping effect. In addition, the hanging portion 332 also has the function of encapsulating the arc-shaped bending portion 324 of the first conductive sheet 322 and the second conductive sheet 323.

The conductive sheet encapsulation part 333 surrounds and is combined with the outer edge of the suspension part 332. The conductive sheet encapsulation part 333 and the suspension part 332 are connected with the first conductive sheet 322, the second conductive sheet 323 and their arc-shaped bending parts. 324 are sealed and attached to each other as one body, and the diaphragm supporting part 331 sealingly covers the extending plane 325 from above.

The coil encapsulation part 334 encapsulates at least one vertical plane voice coil 310 and is integrated with the suspension part 332 and/or the conductive sheet encapsulation part 333. In this way, the encapsulation film 330 can integrate the vertical plane voice coil 310 and the diaphragm. 321. The first conductive sheet 322 and the second conductive sheet 323 are sealed as a whole, and the bottom surfaces of the sealed first conductive sheet 322, the second conductive sheet 323, and the diaphragm supporting part 331 can be located on the same plane.

As shown in Figure 9, during assembly, the encapsulated first conductive sheet 322 and the second conductive sheet 323 are placed on the plane bracket 110, and the diaphragm 321 and the suspension portion 332 are suspended in the central opening 111. And the vertical planar voice coil 310 is embedded in the movable gap 215, so that a complete planar speaker structure 100 can be completed.

Since both the first conductive sheet 322 and the second conductive sheet 323 have a plate-like structure rather than a line structure, they are vertical to the planar voice coil 310, the first conductive sheet 322, the second conductive sheet 323, the diaphragm 321, and the packaged film. After 330 is packaged into an integral structure, the packaging film 330 also bears the vibration force exerted on the first conductive sheet 322 and the second conductive sheet 323 when the diaphragm 321 vibrates.

Furthermore, since the first conductive sheet 322 and the second conductive sheet 323 are stably arranged on the planar support 110 instead of thin wires and suspended vibrations, the vibration stability during movement can be improved, and the quality and rigidity can be increased. It can improve the shortcomings of conventional small speakers whose signal leads are prone to disconnection when working at high power or for a long time.

In addition, the first conductive sheet 322 and the second conductive sheet 323 are also part of the suspension system. By optimizing their geometric shapes and positions, the elongated diaphragm 321 can be improved in vibration due to the long and short sides. If the proportion difference is too large, it will easily cause deformation and distortion problems.

As shown in Figure 10, Inv-1W, Inv-2W, Inv-3W, Inv-4W, and Inv-5W in the figure respectively represent the 1 watt, 2 watt, 3 watt, 4 watt, and 5 watts of this embodiment.
