Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate.

In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

According to one embodiment of the present disclosure, a socket device of a sound emitting device is provided. As shown in fig. 1, the outlet device includes a cylindrical side wall portion 19 and a bottom portion 17 provided at one end of the cylindrical side wall portion 19 in a sealing manner. The cylindrical side wall portion 19 and the bottom portion 17 enclose a cavity with one open end. The cavity is used for accommodating the magnetic circuit system.

A plurality of terminals are provided on the outer surface of the bottom portion 17. The plurality of connection terminals include a first terminal 15. The first terminal 15 has a first side edge 151 opposite the outer surface. For example, the first terminal 15 has a sheet structure, a columnar structure, or the like. The body of the first terminal 15 is oriented perpendicular or inclined to the bottom 17. The main body direction is, for example, an extending direction of a main surface of the sheet structure, an axial direction of the columnar structure, or the like. The side of the first terminal 15 facing away from the bottom 17 is a first side edge 151. The first side edge 151 is directed upward or substantially upward.

As shown in fig. 3, the first and second catching

grooves

15b and 15a are formed by the first side edges 151 being inwardly recessed. The first catching groove 15b is configured for connection with a conductor of the first member. The second catching groove 15a is configured for connection with a conductor of the second member. The conductor is, for example, a wire, a spring, a lead, or the like.

The first and second components may be, but are not limited to, a voice coil, a capacitor 11, a resistive device, an inductive device, a sensor, a PCB, an MCU, etc.

When the connection is performed, firstly, the conductor of the first component is clamped into the first clamping groove 15 b; then, the conductor is fixed in the first engaging groove 15b by soldering. Similarly, the conductor of the second member is first snapped into the second snap groove 15a and then welded in the second snap groove 15 a.

In the embodiment of the present disclosure, the openings of the first clamping groove 15b and the second clamping groove 15a are both deviated from the bottom 17, i.e., face upward, so that other objects do not need to be avoided when the conductor of the first component and the conductor of the second component are clamped, the clamping operation is very easy, and the method is suitable for industrial production.

In addition, the layout mode that the opening of the first terminal 15 faces upwards reduces the number of times that the conductor is bent, and the structure of the conductor can be simpler and the assembly is easier.

Further, the bottom 17 is made of plastic. The terminals are fixed to the bottom 17 by insert molding. This makes the fixing of the terminal easier.

For example, as shown in fig. 1, the first terminal 15 is injection molded on the bottom portion 17. A boss 14 surrounding the first terminal 15 is formed on the bottom 17. The bosses 14 can effectively fix the position of the first terminal 15, and improve the connection strength between the first terminal 15 and the bottom 17.

Of course, the base 17 and the terminal may be formed separately and then fixed together by means of insertion, bonding, welding, or the like.

Preferably, as shown in fig. 1, the main body of the first terminal 15 is oriented perpendicular to the bottom 17. This kind of setting mode has avoided producing stress concentration problem easily at the root when first terminal 15 inclines to set up, has improved the joint strength of first terminal 15 with bottom 17, is convenient for the conductor card to go into in first joint groove 15b, the second joint groove 15 a.

In one example, as shown in fig. 3, the cross-sectional shape of the second catching groove 15a is a circle having an open end, which forms a closing structure. For example, the mouth and the tip of the second catching groove 15a are larger in size than the diameter of the conductor of the second member, and the middle is smaller in size than the diameter of the conductor, so that the conductor is easily caught in the second catching groove 15a but is not easily released from the second catching groove 15 a. In general, the cross-section of the conductor is circular. The circular configuration more effectively secures the conductors.

In other examples, the second snap groove 15a can form an interference fit with the conductor. This effectively prevents the conductor from moving axially along it.

In one example, the open end is V-shaped or U-shaped, as shown in FIG. 3. The open end of the V-shape or U-shape can function as a guide, which enables the conductor to be more easily snapped into the second snap groove 15 a.

Of course, the shape of the open end is not limited to the above-described embodiment, and can be set by those skilled in the art according to actual needs.

In one example, the second catching groove 15a is rounded at a side contacting the conductor. The round angle has a smooth and round surface, which is beneficial to fixing the conductor and can not cut off the conductor.

In one example, as shown in fig. 3, the first catching groove 15b has a bar shape, a wavy line shape, or a zigzag line shape. The first catching grooves 15b are used for connecting thin wires, such as the

leads

12a,12b of the voice coil. The lead is clamped in the first clamping groove 15b before soldering is performed. The first catching groove 15b of the above shape can effectively fix the lead wire and the height of the lead wire is fixed.

In one example, as shown in fig. 1, the plurality of connection terminals further includes a second terminal 13. As shown in fig. 2, the second terminal 13 includes a third card recess 13a and a fourth card recess 13b formed by recessing the second side edge. The second side edge is any side edge of the second terminal 13, for example, a side edge parallel to the bottom portion 17. The cross-sectional shape of the third catching groove 13a is a circle 132 having an open end, and the open end 131 forms a closing-in structure. For example, the open end 131 is a V-shaped or U-shaped structure. The fourth catching groove 13b is in a bar shape, a wavy line shape, or a zigzag shape. The fourth catching groove 13b communicates with the bottom of the third catching groove 13 a.

In this example, the third engaging groove 13a and the fourth engaging groove 13b are communicated with each other, and they are stacked. The third clamping groove 13a and the fourth clamping groove 13b are respectively connected with different conductors, and the two conductors are stacked. In this example, the second terminals 13 have a simple structure, and the space occupied by the second terminals 13 is smaller than that occupied by two engaging grooves arranged in parallel.

In the connection, the second terminal 13 may be connected to both conductors. For example, one conductor (e.g., the

lead wires

12a,12b of the voice coil) is first snapped into the fourth snap groove 13 b; and another conductor (e.g., the

wires

11a, 11b of the capacitor 11) is snapped into the third snap groove 13 a.

Only one conductor may be connected to each second terminal 13. Since the second terminal 13 has two kinds of catching

grooves

13a,13b, it is possible to adapt the connection of conductors of different sizes.

In one example, as shown in fig. 1 and 2, the second terminal 13 has a plate-like structure and is parallel to the outer surface. For example, the opening of the third connection terminal faces in the horizontal direction, which makes the conductor snapping-in easier and the positioning accuracy high.

In one example, as shown in fig. 1, the second terminal 13 is provided in plurality. The plurality of second terminals 13 are insulated from each other and connected by a plug connector. The plug is detachably connected to the base 17. For example, the plug is a plug of an external device. The plurality of second terminals 13 form a passage when the plug is inserted. When the plug is pulled out, the plurality of second terminals 13 form an open circuit.

In one example, as shown in fig. 1, the first component is a voice coil and the second component is a capacitor 11. One lead of the voice coil is connected to one lead of the capacitor 11 through the first terminal 15. For example, the voice coil includes a first lead 12a and a second lead 12 b. The capacitor 11 includes a first conductive line 11a and a second conductive line 11 b. Generally, the lead of the capacitor 11 is larger with respect to the lead diameter of the voice coil.

The second lead 12b is connected in the first catching groove 15b of the first terminal 15, and the first wire 11a is connected in the second catching groove 15a of the first terminal 15. The number of the second terminals 13 is two, and one of the second terminals 13 is connected to the other lead wire (e.g., the first lead wire 12a) of the voice coil. The other second terminal 13 is connected to another wire (for example, the second wire 11b) of the capacitor 11.

In this example, the capacitor 11 and the voice coil form a closed loop by the first terminal 15 and the two second terminals 13. When the plug is inserted into the insertion hole 16 of the outlet device, the capacitor 11 and the voice coil are conducted; when the plug is pulled out, the capacitor 11 and the voice coil are disconnected. The capacitor 11 can function as a filter when the voice coil is in operation.

In one example, as shown in fig. 3, a through-hole 18 is provided in the middle of the terminal. For example, the terminal is made of metal such as brass or stainless steel, and the through hole 18 is formed by press molding. The through hole 18 is a circular hole, a rectangular hole, a triangular hole, or a hole of other shape. The through hole 18 can play a limiting role during injection molding of the mold.

According to another embodiment of the present disclosure, a sound generating device is provided. Such as a horn device. The sound production device comprises the socket device.

For example, the sound generating device includes a magnetic circuit system and a vibration system. The magnetic circuit system comprises a T iron and an annular permanent magnet arranged outside the T iron. The annular permanent magnet is axially magnetized. The T iron is low-carbon steel. A magnetic gap is formed between the core leg of the T-iron and the annular permanent magnet. The T-bar is fixed within the cavity of the header assembly and is located on the opposite side of the base 17 from the capacitor 11.

The sound generating device further comprises a balancer. The balancer is a cylindrical structure. The balancer is connected to one end of the cylindrical side wall portion 19, for example, by a snap fit. The vibration system comprises a vibrating diaphragm, a voice coil assembly, a ball top and the like. A voice coil assembly is disposed within the balancer. The upper end of the voice coil component is connected with the vibrating diaphragm. The outer edge of the diaphragm is fixed at the end of the balancer opposite to the socket device. The middle part of the vibrating diaphragm is provided with a ball top.

The voice coil assembly includes a voice coil bobbin and a voice coil wound on an outer surface of the voice coil bobbin. The voice coil framework also comprises an empty area which is not wound with the voice coil. The middle part of the vibrating diaphragm is connected with the vacant area of the voice coil framework. The voice coil is located within the magnetic gap.

The lead wire of the voice coil is led out from the voice coil and finally reaches the outer surface. The leads of the voice coil are connected to the leads of the capacitor 11 in the manner described above.

In one example, the voice coil is plural. The plurality of voice coils can obviously improve the driving force of the vibration system and improve the sound production power of the sound production device. The sound generating device is suitable for a vehicle-mounted sound generating device. For example, the number of voice coils is two. Each voice coil is connected with two leads. The lead of each voice coil is looped through the above-mentioned terminal and the capacitor 11.
