Description

Technical Field

[0001] This application relates to the field of transducer technology, and in particular to a transducer and an electronic device including the transducer. Background Technology

[0002] A transducer can convert electrical energy and vibrational energy into each other. For example, alternating current can be passed through the voice coil inside the transducer, which is in a magnetic field. Under the influence of the magnetic field, the voice coil will reciprocate. For traditional transducers, when the electrical input power is constant, the vibrational energy generated by the transducer is relatively small, resulting in a relatively low conversion rate of electrical energy to vibrational energy, thus affecting the energy conversion efficiency of the transducer. Utility Model Content

[0003] One of the technical problems addressed by this application is how to improve the energy conversion efficiency of the transducer.

[0004] A transducer includes a transducer comprising:

[0005] A magnetic mechanism, comprising interconnected magnetic units and positioning elements;

[0006] A first magnetic conductive element is disposed around the magnetic unit, and a magnetic gap is disposed between the first magnetic conductive element and the magnetic unit surrounding the magnetic unit;

[0007] The support mechanism includes a first suspension member and a second suspension member disposed at opposite ends of the first magnetic conductive member. The opposite ends of the positioning member are respectively connected to the first suspension member and the second suspension member. Both the first suspension member and the second suspension member have vibration gaps with the magnetic unit.

[0008] A coil is fixedly disposed within the magnetic gap and surrounds the magnetic unit.

[0009] In one embodiment, the coil is fixedly connected to the first magnetic conductor.

[0010] In one embodiment, the coil is attached to the inner wall surface of the first magnetic conductor.

[0011] In one embodiment, the coil includes a first winding section and a second winding section extending axially along the magnetic mechanism and rotating in opposite directions, the first winding section being disposed near the first suspension member and the second winding section being disposed near the second suspension member.

[0012] In one embodiment, the coil includes a plurality of winding layers connected at their ends in sequence, the plurality of winding layers being arranged along an axis perpendicular to the magnetic mechanism.

[0013] In one embodiment, the length of the coil in the axial direction of the magnetic mechanism is greater than or equal to the length of the magnetic unit.

[0014] In one embodiment, the transducer further includes a lead wire, and a through hole is provided at one end of the first magnetic conductor near the first suspension member. The through hole connects the magnetic gap to the outside, and the lead wire passes through the through hole and is connected to the end of the coil.

[0015] In one embodiment, the width of the magnetic gap is 0.01 mm to 3 mm; or the width of the vibration gap is 0.01 mm to 15 mm.

[0016] In one embodiment, at least one of the following schemes is also included:

[0017] The magnetic unit includes a magnetic component and a second magnetic conductive component. The magnetic component has the second magnetic conductive component at both ends. The positioning component passes through the magnetic component and the second magnetic conductive component.

[0018] The positioning element includes a through section and two positioning sections. The cross-sectional dimension of the positioning section is larger than that of the through section. The through section is inserted into the magnetic unit. The two positioning sections are disposed at both ends of the through section and are respectively connected to the first suspension member and the second suspension member. The magnetic unit abuts between the two positioning sections.

[0019] In one embodiment, the positioning element and the magnetic unit are coaxially arranged.

[0020] In one embodiment, a connector is also included, wherein there are multiple transducers arranged at intervals along the axial direction of the transducers, and the connector is connected between a first suspension member and a second suspension member of two adjacent transducers.

[0021] An electronic device comprising the transducer described in any one of the preceding descriptions.

[0022] One technical advantage of one embodiment of this application is that, given that the two ends of the positioning member are respectively connected to the first suspension member and the second suspension member, and both the first and second suspension members have vibration gaps with the magnetic unit, and the coil is fixedly disposed within the magnetic gap, when the magnetic field within the magnetic gap generates a magnetic force on the coil, this magnetic force will react on the magnetic unit, causing the magnetic unit to vibrate. Since the first and second suspension members constrain both ends of the magnetic unit, it can be ensured that the magnetic unit always vibrates along the axial direction of the positioning member, avoiding vibration in a direction at an angle to the axial direction of the positioning member, i.e., avoiding rolling vibration. This, on the one hand, prevents the magnetic unit from colliding with the first magnetic conductor or the coil due to rolling vibration, avoiding energy damage caused by collision, thereby improving the energy conversion rate, i.e., improving the energy conversion and utilization rate of the transducer. On the other hand, the width of the magnetic gap can be reasonably reduced to avoid rolling vibration, thereby avoiding magnetic field loss within the magnetic gap. This allows for a reasonable increase in the magnetic field strength within the magnetic gap, which in turn increases the driving force of the magnetic field on the magnetic unit, i.e., increases the vibration energy of the magnetic unit, further improving the conversion rate of electrical energy to magnetic field energy, i.e., further improving the energy conversion and utilization rate of the transducer.

[0036] See Figure 1 , Figure 2 and Figure 3One embodiment of this application provides a transducer 10, which includes a transducer 11. The transducer 11 includes a magnetic mechanism 100, a first magnetic conductor 200, a support mechanism 300, and a coil 400. The magnetic mechanism 100 includes a magnetic unit 110 and a positioning member 120, which are fixedly connected to each other. The first magnetic conductor 200 is disposed around the magnetic unit 110, and a magnetic gap 210 is provided between the first magnetic conductor 200 and the magnetic unit 110. The magnetic gap 210 is approximately annular and is disposed around the magnetic unit 110. The support mechanism 300 includes a first suspension member 310 and a second suspension member 320, which are spaced apart along the axial direction of the magnetic mechanism 100. The first suspension member 310 is fixedly connected to one end of the first magnetic conductor 200, and the second suspension member 320 is fixedly connected to the other end of the first magnetic conductor 200. The magnetic mechanism 100 is located between the first suspension member 310 and the second suspension member 320 along its axial direction. One end of the positioning member 120 is fixedly connected to the first suspension member 310, and the other end of the positioning member 120 is fixedly connected to the second suspension member 320; that is, the opposite ends of the positioning member 120 are respectively fixedly connected to the first suspension member 310 and the second suspension member 320. Along the axial direction of the magnetic mechanism 100, both the first suspension member 310 and the second suspension member 320 maintain a non-contact relationship with the magnetic unit 110, resulting in a vibration gap 330 between both the first suspension member 310 and the second suspension member 320 and the magnetic unit 110. The coil 400 is fixedly disposed within the magnetic gap 210 and surrounds the magnetic unit 110. The first suspension member 310 is fixedly connected to one end of the first magnetic conductor 200, and the second suspension member 320 is fixedly connected to the other end of the first magnetic conductor 200. This can be understood as the first suspension member 310 and the second suspension member 320 being connected to the two end faces of the first magnetic conductor 200, or as the first suspension member 310 and the second suspension member 320 being connected to positions on the side of the first magnetic conductor 200 near the two end faces.

[0037] See Figure 1 and Figure 4 During operation, the magnetic gap 210 between the first magnetic conductor 200 and the magnetic unit 110 contains a magnetic field, allowing alternating current to be passed through the coil 400. Since the alternating current in the coil 400 cuts the magnetic field lines, the magnetic field will generate a magnetic force on the coil 400 (e.g., ...). Figure 4 (Indicated by the single arrow in the thick solid line) This magnetic force is the Lorentz force. Since coil 400 is fixed to the first magnetic conductor 200, coil 400 remains stationary, and magnetic unit 110 will experience a reaction force from coil 400 (such as...). Figure 4The single arrow (indicated by the thick dashed line) can be understood as the magnetic force acting on the magnetic unit 110, thus causing the magnetic unit 110 to reciprocate along its axial direction under the influence of the magnetic force (e.g., ...). Figure 4 (As indicated by the double arrows in the thick solid line), this allows the transducer 11 and the entire transducer device 10 to convert electrical energy into vibrational energy. It can be understood that, due to the existence of the vibration gap 330, the interference of the support mechanism 300 on the magnetic unit 110 along the axial direction of the magnetic mechanism 100 can be effectively eliminated. The vibration gap 330 provides a good clearance space for the vibration of the magnetic unit 110, thus ensuring that the magnetic unit 110 can generate vibration smoothly.

[0038] In existing technologies, the magnetic mechanism 100 is typically fixed, with one end of the coil 400 suspended and the other end free. This can be understood as one end of the coil 400 being constrained while the other end remains free. When the coil is energized, it vibrates within the magnetic gap 330. Since the other end of the coil 400 is free, during its vibration, in addition to vibrating along the axial direction of the magnetic mechanism 100, the coil 400 also vibrates in a direction at an angle to the axial direction of the magnetic mechanism 100. This diversifies and disrupts the vibration direction of the coil 400, ultimately causing it to roll. When this rolling occurs, the coil 400 is prone to colliding with the first magnetic conductor 200 and the magnetic unit 110, resulting in energy loss due to these collisions. This reduces the conversion rate of electrical energy into coil rotational energy, thus reducing the effective utilization rate of electrical energy. To reduce the impact of rolling vibration, i.e., to reduce the collision between coil 400 and the first magnetic conductor 200 and magnetic unit 110, the width of magnetic gap 330 is usually increased. This will result in a greater loss of magnetic field strength within magnetic gap 330, making the magnetic field strength within magnetic gap 330 lower, thereby reducing the driving ability of the magnetic field on the coil. Therefore, the vibration of coil 400 will be weakened, which will also reduce the conversion rate of electrical energy.

[0039] See Figure 1 and Figure 4Regarding the transducer 11 in the above embodiment, since the two ends of the positioning member 120 are fixedly connected to the first suspension member 310 and the second suspension member 320 respectively, it can be understood that the two ends of the entire magnetic unit 110 are suspended on the first suspension member 310 and the second suspension member 320 respectively through the positioning member 120. Therefore, by constraining both ends of the magnetic unit 110 through the first suspension member 310 and the second suspension member 320, it can be ensured that the magnetic unit 110 always vibrates along the axial direction of the positioning member 120, avoiding vibration of the magnetic unit 110 in a direction that forms an angle with the axial direction of the positioning member 120, i.e., avoiding rolling vibration. Since rolling vibration can be avoided, on the one hand, it can prevent the magnetic unit 110 from colliding with the first magnetic conductor 200 or the coil 400 due to the effect of rolling vibration, avoiding energy damage caused by collision, thereby improving the conversion rate of electrical energy, i.e., improving the energy conversion rate and utilization rate of the transducer 11. On the other hand, the width of the magnetic gap 210 can be reasonably reduced, thereby avoiding magnetic field loss within the magnetic gap 210. This reasonably increases the magnetic field strength within the magnetic gap 210, thereby increasing the driving force of the magnetic field on the magnetic unit 110, that is, increasing the vibration energy of the magnetic unit 110, further improving the conversion rate of electrical energy and magnetic field energy, that is, further improving the energy conversion rate and utilization rate of the transducer 11.

[0040] See Figure 1 and Figure 4 In some embodiments, the positioning element 120 can be coaxially arranged with the magnetic unit 110; in other words, the positioning element 120 is located at the center of the magnetic unit 110. The magnetic unit 110 includes a magnetic element 111 and a second magnetic conductive element 112. The magnetic element 111 can be a permanent magnet, and both the second magnetic conductive element 112 and the first magnetic conductive element 112 can be made of high-permeability materials such as cold-rolled low-carbon steel. The magnetic element 111 is a bar magnet, and there are two second magnetic conductive elements 112, with the second magnetic conductive element 112 located at both ends of the magnetic element 111. The positioning element 120 passes through the magnetic element 111 and the second magnetic conductive element 112. For example, the end of the magnetic element 111 near the first suspension element 310 can be an N pole, and the end of the magnetic element 111 near the second suspension element 320 can be an S pole. Under the focusing effect of the second magnetic conductor 112, the magnetic lines of force generated by the magnetic conductor 111 start from the N pole, then pass through the magnetic gap 210 to reach the first magnetic conductor 200, and then return from the first magnetic conductor 200 to the S pole of the magnetic conductor 111 through the magnetic gap 210, thus forming a loop of magnetic lines of force.

[0041] See Figure 1 and Figure 4In some embodiments, the positioning member 120 can be a riveted member, etc. The positioning member 120 includes a through section 121 and a positioning section 122. There are two positioning sections 122, which are disposed at both ends of the through section 121. The two positioning sections 122 are fixedly connected to the first suspension member 310 and the second suspension member 320, respectively. The magnetic member 111 and the magnetic conductive member 112 are both provided with through holes 113. The through section 121 cooperates with the through hole 113, so that the through section 121 passes through the magnetic member 111 and the magnetic conductive member 112. The two positioning sections 122 cannot enter the through hole 113, so the two positioning sections 122 are located outside the through hole 113. When the two positioning sections 122 are fixedly connected to the first suspension member 310 and the second suspension member 320, the entire magnetic unit 110 is abutted and clamped between the two positioning sections 122, thus realizing the fixed connection relationship between the positioning member 120 and the magnetic unit 110. In other embodiments, the positioning element 120 may also be fixedly connected to the magnetic unit 110 and the support mechanism 300 by means of adhesive bonding or welding.

[0042] See Figure 4 In some embodiments, the width A of the magnetic gap 210 is 0.01 mm to 3 mm. For example, the width A of the magnetic gap 210 can be 0.01 mm, 1 mm, 1.5 mm, or 3 mm, which can ensure that there is a reasonable magnetic field strength within the magnetic gap 210. The width B of the vibration gap 330 is 0.01 mm to 15 mm. For example, the width B of the vibration gap 330 can be 0.01 mm, 1 mm, 2 mm, 5 mm, 9 mm, or 15 mm, which provides good clearance space for the vibration of the magnetic unit 110. For example, when the amplitude of the magnetic unit 110 is large, the width of the vibration gap 330 can be appropriately increased.

[0043] If the magnetic mechanism 100 is fixed, one end of the coil 400 is suspended and the other end is free, in order for the coil 400 to vibrate, a certain gap needs to be maintained between the coil 400 and the first magnetic conductor 200 and the magnetic unit 110, thereby increasing the width of the magnetic gap 210. This will weaken the magnetic field strength within the magnetic gap 210, thereby weakening the driving force of the magnetic field on the coil 400, that is, reducing the vibration energy of the magnetic unit 110, thereby reducing the energy conversion rate and utilization rate of the transducer 11.

[0044] See Figure 1 and Figure 4In some embodiments, the coil 400 is attached to the inner wall of the first magnetically conductive element 200, and the coil 400 is fixedly connected to the inner wall of the first magnetically conductive element 200, so that the coil 400 is fixed within the magnetic gap 210. This eliminates the gap between the coil 400 and the first magnetically conductive element 200; only a gap needs to be maintained between the coil 400 and the magnetic unit 110. This further effectively reduces the width of the magnetic gap 210, thereby increasing the magnetic field strength within the magnetic gap 210, enhancing the driving force of the magnetic field on the coil 400, i.e., increasing the vibrational energy of the magnetic unit 110, and ultimately improving the energy conversion and utilization rate of the transducer 11. For example, see [reference needed]. Figure 6 The coil 400 can be attached to the inner wall of the first magnetic conductive element 200, but the coil 400 may not be fixedly connected to the inner wall of the first magnetic conductive element 200. In this case, the coil 400 can be fixedly connected to the positioning section 122 of the positioning element 120 through the fixing element 440, so that the coil 400 and the positioning element 120 are fixedly connected. This can also fix the coil 400 in the magnetic gap 210 and eliminate the gap between the coil 400 and the first magnetic conductive element 200.

[0045] See Figure 1 and Figure 4 In some embodiments, the length of the coil 400 in the axial direction of the magnetic mechanism 100 is greater than or equal to the length of the magnetic gap 210. For example, the length of the coil 400 can be approximately equal to the length of the magnetic gap 210. It is understood that the magnetic field lines are more densely distributed in the region of the magnetic gap 210 near the N and S poles of the magnetic element 111, thus the region of the magnetic gap 210 near the N and S poles of the magnetic element 111 has a larger magnetic field strength. In other embodiments, both ends of the coil 400 protrude a certain length relative to the magnetic mechanism 100 in the axial direction of the magnetic mechanism 100, and this protrusion length can be from 0 mm to 30 mm.

[0046] If the magnetic mechanism 100 is fixed, one end of the coil 400 is suspended, and the other end is free, in order to avoid interfering with the vibration of the coil 400, the free end of the coil 400 is usually kept at a distance from the S pole of the magnetic component. Therefore, the coil 400 only extends into the region of the magnetic gap 210 near the N pole of the magnetic component, and cannot extend into the region of the magnetic gap 210 near the S pole of the magnetic component. As a result, the coil 400 is driven by the magnetic field in the region of the magnetic gap 210 near the N pole of the magnetic component 111, while the magnetic field in the region of the magnetic gap 210 near the S pole of the magnetic component 111 cannot be effectively utilized to drive the vibration of the coil 400. This will affect the utilization rate of the magnetic field energy in the magnetic gap 210, as well as the driving force of the magnetic field on the coil 400, thereby affecting the energy conversion rate and utilization rate of the transducer 11.

[0047] Regarding the transducer 11 in the above embodiment, since the length of the coil 400 is greater than or equal to the length of the magnetic gap 210, it can be ensured that the coil 400 simultaneously extends into the region near the N pole and S pole of the magnetic component 111 within the magnetic gap 210. This allows the magnetic field in the region near the N pole and S pole of the magnetic component 111 within the magnetic gap 210 to simultaneously drive the magnetic unit 110 to vibrate under the reaction force of the coil 400. In this way, the magnetic field energy in the region near the N pole and S pole of the magnetic component 111 within the magnetic gap 210 can be effectively utilized, thereby increasing the driving force of the magnetic field on the magnetic unit 110, and thus improving the energy conversion rate and utilization rate of the transducer 11.

[0048] See Figure 1 and Figure 4 In some embodiments, the coil 400 includes a first winding section 410 and a second winding section 420, which are generally helical and extend along the axial direction of the magnetic mechanism 100. The first winding section 410 and the second winding section 420 have opposite directions of rotation, for example, the first winding section 410 is left-handed and the second winding section 420 is right-handed. The first winding section 410 is disposed close to the first suspension member 310, such that the first winding section 410 is located in the region within the magnetic gap 210 near the N pole of the magnetic member 111; the second winding section 420 is disposed close to the second suspension member 320, such that the second winding section 420 is located in the region within the magnetic gap 210 near the S pole of the magnetic member 111. By reversing the rotation directions of the first winding segment 410 and the second winding segment 420, the magnetic force exerted by the magnetic field on the coil 400 on the first winding segment 410 and the second winding segment 420 becomes equal. Consequently, the reaction forces exerted by both the first winding segment 410 and the second winding segment 420 on the magnetic unit 110 become equal, thus driving the magnetic unit 110 to effectively vibrate. In other embodiments, the coil 400 may include only the first winding segment 410 or only the second winding segment 420. The magnetic unit 110 can still be driven to effectively vibrate.

[0049] See Figure 1 and Figure 4 In some embodiments, the coil 400 includes a plurality of winding layers 430 connected in sequence at their ends. The plurality of winding layers 430 are arranged along an axial direction perpendicular to the magnetic mechanism 100. The same winding layer 430 may include a first winding segment 410 and a second winding segment 420. By providing a plurality of winding layers 430, the driving force of the coil 400 on the magnetic unit 110 can also be increased, thereby improving the energy conversion rate and utilization rate of the transducer 11.

[0050] See Figure 1 and Figure 4In some embodiments, the transducer 11 further includes leads 500. A through hole 220 is provided at one end of the first magnetic conductor 200 near the first suspension member 310. The through hole 220 connects the magnetic gap 210 to the outside. The leads 500 pass through the through hole 220 and are connected to the end of the coil 400. There are two leads 500, each connected to one end of the coil 400. The leads 500 can be used as positive and negative terminals respectively. An external power supply can be connected to the leads 500, allowing alternating current to be supplied to the coil 400 within the magnetic gap 210 through the leads 500. In other embodiments, a through hole 220 is also provided at one end of the first magnetic conductive element 200 near the second suspension element 320. One lead wire 500 passes through the through hole 220 at the end of the first magnetic conductive element 200 near the first suspension element 310, and the other lead wire 500 passes through the through hole 220 at the end of the first magnetic conductive element 200 near the second suspension element 320.

[0051] Referring to 5, in some embodiments, the transducer 10 further includes a connector 12. There are multiple transducers 11 arranged axially along their axes. The connector 12 connects the first suspension member 310 and the second suspension member 320 between two adjacent transducers 11. A clearance gap 340 exists between the magnetic mechanisms 100 of two adjacent transducers 11. By providing multiple transducers 11, multiple magnetic units 110 can vibrate, thereby increasing the vibration energy of the transducer 10. It is understood that during the vibration of the magnetic unit 110, the magnetic unit 110 will also drive the first suspension member 310 and the second suspension member 320 to vibrate relative to the first magnetic conductor 200 via the positioning member 120. The clearance gap 340 provides good clearance space for the vibration of the first suspension member 310 and the second suspension member 320.

[0052] This application also provides an electronic device, which includes the transducer 10, which is disposed inside the electronic device. The electronic device can be a mobile phone or headphones, etc.
