Description

Technical Field

[0001] This invention relates to a planar speaker with a conductive diaphragm and its vertical planar driving mode structure, particularly a planar speaker structure with a vertical planar voice coil and a conductive diaphragm for use in audio equipment, computers, portable electronic devices, or headphones. Background Technology

[0002] like Figure 1 As shown, the conventional loudspeaker P100 mainly consists of a magnet P10, a coil P20, and a speaker diaphragm P30. The coil P20 is fabricated on the speaker diaphragm P30. When a signal current passes through the coil P20, it generates a magnetic field. This magnetic field interacts with the magnetic field of the magnet P10, causing the speaker diaphragm P30 to vibrate. The vibration of the coil P20 and the speaker diaphragm P30 together vibrates the surrounding air, thus producing sound. However, this architecture suffers from problems such as wire breakage or abnormal noise because the lead P40, which provides the signal to the coil, is suspended and frequently vibrates irregularly.

[0003] For example, the patent specification of Taiwan Patent Certificate No. TWI686092B discloses a thin loudspeaker with a voice coil having a spring function, which includes a frame, a magnetic return device, a spring coil, and a diaphragm. The conductor (321) is connected to the external sound source signal through two conductive suspension parts (322, 323). This design makes the two conductive suspension parts (322, 323) like the lead P40 of the coil P20 of the conventional loudspeaker P100, which is suspended and often in an irregular vibration state, thus easily causing problems such as wire breakage or abnormal noise.

[0063] like Figure 2 and Figure 3 As shown, this embodiment is a planar speaker structure 100 with a conductive diaphragm, which includes: a support frame 10; a first magnet 211; a second magnet 212; and a vertical plane driving mode 30. For ease of explanation, the planar speaker structure 100 with a conductive diaphragm in this embodiment will be simply referred to as the planar speaker structure 100.

[0064] The support frame 10 is mainly used to support the vertical plane drive vibration mode 30. Therefore, the support frame 10 has a planar support 110, and a central opening 111 is formed in the central part of the planar support 110. In addition, the support frame 10 can also be used to fix the first magnet 211 and the second magnet 212. For example, multiple support feet 112 extend downward from the planar support 110, thereby effectively fixing the first magnet 211 and the second magnet 212, and providing the height space required for the vertical plane drive vibration mode 30 to vibrate up and down.

[0065] The first magnet 211 is a permanent magnet and is disposed on the first side below the planar support 110; the second magnet 212 is also a permanent magnet and is disposed on the second side below the planar support 110; in order to effectively fix the first magnet 211 and the second magnet 212, a set of upper washers 213 and a set of lower washers 214 can be used to effectively fix the first magnet 211 and the second magnet 212 above and below, respectively.

[0066] The aforementioned upper washer 213, first magnet 211, second magnet 212, and lower washer 214 form a sandwich structure and, within the framework of the support frame 10, form an integral structure. Furthermore, in the central part of the sandwich structure, namely between the two upper washer pieces 213, between the first magnet 211 and the second magnet 212, and between the two lower washer pieces 214, a movable gap 215 is formed.

[0067] like Figure 4 and Figure 5 As shown, the vertical plane driving mode 30 has: at least one vertical plane voice coil 310; a conductive diaphragm 320; and an encapsulation film 330. The at least one vertical plane voice coil 310 and the conductive diaphragm 320 are mutually perpendicular T-shaped structures.

[0068] like Figures 4 to 6 As shown, the vertical plane voice coil 310 is equivalent to the voice coil structure of a general loudspeaker. The vertical plane voice coil 310 is embedded in the movable gap 215. When an audio signal is input into the vertical plane voice coil 310, the vertical plane voice coil 310 will generate a voice coil magnetic field as the audio signal changes. The voice coil magnetic field will interact magnetically with the first magnet 211 and the second magnet 212, causing the vertical plane voice coil 310 to move up and down.

[0069] Since the movable gap 215 only requires a tiny magnetic gap, typically only slightly larger than the thickness of the vertical plane voice coil 310, the vertical plane voice coil 310 can achieve higher magnetic energy conversion efficiency. Furthermore, the magnetic circuit and stroke stacking of the planar speaker structure 100 can be optimized, and the height limitation of the planar speaker structure 100 can be reduced.

[0070] Since the vertical plane voice coil 310 can be a single-layer or multi-layer structure, and because it is a planar copper wire voice coil, it is not limited by the traditional voice coil shape, so it can be made into a thinner, narrower, etc.

[0071] The vertical plane voice coil 310 can be composed of one or more vertical plane voice coils 310. For example, the vertical plane voice coil 310 can have a first vertical plane voice coil 311 and a second vertical plane voice coil 312, and an insulating film 313 is provided between the first vertical plane voice coil 311 and the second vertical plane voice coil 312.

[0072] In addition to being composed of two vertical plane voice coils 310, the vertical plane voice coils 310 can also be composed of three, four or more vertical plane voice coils 310. Furthermore, the electrical connection of the vertical plane voice coils 310 can be a series connection, a parallel connection, or a series / parallel connection.

[0073] The vertical plane voice coil 310 can be used in designs with standard impedance or other special impedance requirements, depending on the acoustic impedance requirements. In terms of electrical advantages, it can reduce nonlinear distortion and total harmonic distortion (THD) and effectively avoid noise (rub & buzz). In terms of temperature resistance, it can withstand high power current. It is particularly suitable for 1-5W power designs and is superior to current miniature speaker applications.

[0074] like Figure 4 and Figure 7 As shown, the conductive diaphragm 320 includes: a diaphragm 321; a first conductive sheet 322; and a second conductive sheet 323. The outwardly extending ends on both sides of the first conductive sheet 322 and the second conductive sheet 323 can be respectively the first sound source input terminal 30a and the second sound source input terminal 30b of the planar speaker structure 100, which facilitates the replacement of the sound source input direction when producing different models of products.

[0075] In order to avoid welding errors during mass production, the first audio input terminal 30a and the second audio input terminal 30b can be designed at both ends of the long axis of the vertical plane voice coil 310, and respectively located on the two corresponding sides of the vertical plane voice coil 310. In this way, even if the vertical plane voice coil 310 is rotated horizontally by 180 degrees during production, there will be no welding error. Furthermore, in the operation mode where the placement direction of the vertical plane voice coil 310 does not need to be considered, production efficiency can be improved.

[0076] The diaphragm 321 is equivalent to the cone of a general loudspeaker. 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 interacts with the first magnet 211 and the second magnet 212 and vibrates up and down, the diaphragm 321 will also vibrate up and down. The vibration of the diaphragm 321 will drive the surrounding air to vibrate and produce sound.

[0077] The first conductive sheet 322 is disposed on the first side of the diaphragm 321 and electrically connected to the first voice coil input terminal 31a of the vertical plane voice coil 310, which is the first welding part; the second conductive sheet 323 is disposed on the second side of the diaphragm 321 and electrically connected to the second voice coil input terminal 31b of the vertical plane voice coil 310, which is the second welding part.

[0078] In order to have good conductivity, both the first conductive piece 322 and the second conductive piece 323 are copper conductive pieces. In addition, by replacing the signal leads of conventional speakers with conductive pieces, the problem of wire breakage caused by the long-term up-and-down vibration of the cone when using copper wire as a signal lead can be completely eliminated.

[0079] Between the first conductive sheet 322 and the second conductive sheet 323 and the first input terminal 31a and the second input terminal 31b of the vertical plane voice coil 310, there may be a heat-resistant and insulating first welding positioning sheet 32a and a second welding positioning sheet 32b, respectively. The first welding positioning sheet 32a and the second welding positioning sheet 32b each have a pair of welding openings 33.

[0080] By means of the welding opening 33, the welding between the first conductive sheet 322 and the first input terminal 31a and the second conductive sheet 323 and the second input terminal 31b can be carried out only at the welding opening 33. This can avoid large-scale welding or excessive solder 33a adhering during welding, which would affect the weight, balance and frequency response of the diaphragm 321.

[0081] The first conductive sheet 322 and the second conductive sheet 323 each have a set of arc-shaped bends 324, and each arc-shaped bend 324 has an extension plane 325 at its end. By means of the curve of the arc-shaped bends 324, the first conductive sheet 322 and the second conductive sheet 323 can have the same curvature as the suspension part 332, so they can fit together perfectly. The extension plane 325 can also serve as a welding part for welding the first conductive sheet 322 and the second conductive sheet 323 to the first input terminal 31a and the second input terminal 31b.

[0082] In order to avoid interference from the stress of the arc-shaped bend 324 and the extended plane 325 on the suspension part 332 during up-and-down vibration, thereby affecting the compliance restoring force and damping effect of the suspension part 332, multiple perforations 326 can be provided on the arc-shaped bend 324 and / or the extended plane 325 at the end of the arc-shaped bend 324, so as to reduce the stress of the arc-shaped bend 324 and the extended plane 325.

[0083] like Figure 8 As shown, the encapsulation film 330 has: a diaphragm support portion 331; a suspension portion 332; a conductive sheet encapsulation portion 333; and a coil encapsulation portion 334.

[0084] The diaphragm support 331 is planar and extends from below the diaphragm 321, and is tightly fitted together with the diaphragm 321.

[0085] The suspension portion 332, which surrounds and is integrated with the outer edge of the diaphragm support portion 331, can be a semi-circular arc-shaped structure in cross-section. The suspension portion 332 is equivalent to the suspension edge around the cone of a typical loudspeaker. The suspension portion 332 primarily supports the vibration system of the diaphragm 321 and provides compliance restoring force and damping. Furthermore, the suspension portion 332 also encapsulates the arc-shaped bends 324 of the first conductive sheet 322 and the second conductive sheet 323.

[0086] The conductive sheet encapsulation part 333 surrounds and is attached to the outer edge of the suspension part 332. The conductive sheet encapsulation part 333 and the suspension part 332 are sealed and bonded together with the first conductive sheet 322 and the second conductive sheet 323 and their arc-shaped bending part 324. The diaphragm support part 331 seals and covers the extended plane 325 from above.

[0087] The coil encapsulation part 334 encapsulates at least one vertical plane voice coil 310 and integrates it with the suspension part 332 and / or the conductive sheet encapsulation part 33. In this way, the encapsulation film 330 can seal the vertical plane voice coil 310, the diaphragm 321, the first conductive sheet 322 and the second conductive sheet 323 into one unit. Furthermore, the bottom surfaces of the encapsulated first conductive sheet 322, the second conductive sheet 323 and the diaphragm support part 331 can be located on the same plane.

[0088] like Figure 9 As shown, during assembly, the first conductive sheet 322 and the second conductive sheet 323 after encapsulation are set on the planar support 110, and the diaphragm 321 and the suspension part 332 are suspended at the central opening 111, and the vertical plane voice coil 310 is embedded in the movable gap 215, thus completing the complete planar speaker structure 100.

[0089] Since the first conductive sheet 322 and the second conductive sheet 323 are both plate-shaped structures rather than linear structures, and the vertical plane voice coil 310, the first conductive sheet 322, the second conductive sheet 323, and the diaphragm 321 are encapsulated into an integral structure by the encapsulation film 330, the encapsulation film 330 also bears the vibration force applied to the first conductive sheet 322 and the second conductive sheet 323 when the diaphragm 321 vibrates.

[0090] Furthermore, since the first conductive sheet 322 and the second conductive sheet 323 are stably mounted on the planar support 110 rather than being thin wires and suspended in the air, the vibration stability during movement can be improved, and the mass and rigidity can be increased. Therefore, it can improve the shortcomings of conventional small speakers, whose signal leads are prone to breakage when operating at high power or for a long time.

[0091] In addition, the first conductive sheet 322 and the second conductive sheet 323 are also part of the suspension system. By optimizing their geometry and position, the deformation and distortion problems that are easily caused by the large difference in the ratio of the long and short sides of the slender diaphragm 321 during vibration can be improved.

[0092] like Figure 10 As shown in the figure, Inv-1W, Inv-2W, Inv-3W, Inv-4W, and Inv-5W represent the frequency response curves of this embodiment at power outputs of 1 watt, 2 watts, 3 watts, 4 watts, and 5 watts, respectively. Pr-1W and Pr-2W represent the frequency response curves of conventional loudspeakers at power outputs of 1 watt and 2 watts, respectively. From the relevant curves, it can be seen that this embodiment has better sound intensity performance in all frequency bands.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
