Description

Technical Field

[0001] The utility model relates to the field of loudspeakers, in particular to a soldering pad bracket and a loudspeaker containing the soldering pad bracket. Background Art

[0002] Loudspeakers, also known as horns, are very common electroacoustic transducers that convert electrical signals into sound signals. Among them, paper cone electric speakers are the most widely used, and their structure mainly consists of three parts, namely the vibration system, magnetic circuit system and auxiliary system. The vibration system includes paper discs, voice coils and centering supports, etc.; the magnetic circuit system includes Yongyi magnets, magnetic plates and field core columns, etc.; the auxiliary system includes basin frames, wiring boards, edge clamps and dust covers, etc.

[0003] During the installation of the speaker, it is very important to identify and connect the pin polarity. Common speakers have one pad for each positive and negative pole, and the direction of the positive and negative leads is fixed after the speaker is produced. During the connection of the speaker to the circuit board, the position of the speaker cannot be adjusted during the connection process because the positive and negative poles of the speaker are fixed, which increases the difficulty of connection and installation, especially for square speakers. Summary of the invention

[0004] The utility model aims to provide a solder pad bracket of a speaker and a speaker comprising the solder pad bracket, wherein the speaker can lead out positive and negative electrode leads from the solder pad in different directions, which is convenient for connection and installation.

[0005] The purpose of the utility model is achieved through the following technical solutions: The overall structure of the loudspeaker of the utility model is square, and is mainly composed of a basin frame, a cover plate, a vibration plate, a magnetic bowl, a magnet, a pole piece, a voice coil, a diaphragm and a pad bracket. The basin frame is located on the outside of the loudspeaker, and a magnetic bowl is arranged above the basin frame, a magnet is arranged above the magnetic bowl, and a pole piece is arranged above the magnet. The voice coil is located in the gap formed by the magnetic bowl, the magnet and the pole piece. A diaphragm is arranged around the voice coil, and a vibration plate is arranged on the top of the voice coil. A cover plate is arranged at the top of the basin frame.

[0006] When the voice coil is energized, a magnetic field is generated around the voice coil, and interacts with the magnetic field generated by the magnet and the magnetic bowl, forming a push-pull force, pushing or pulling the diaphragm to vibrate, forming a resonance with the surrounding air and producing sound.

[0007] A pad bracket is provided at the bottom of the entire speaker. The pad bracket is square, and its size fits the shape of the bottom of the speaker basin frame. The main components of the pad bracket are composed of pads and conductive plates. The pads are divided into a first pad, a second pad and a third pad, wherein the first pad is independent of the second pad and the third pad, and the second pad and the third pad are connected to each other through a conductive plate. The conductive plate is made of a conductive material, such as metal, which can achieve electrical connectivity between the second pad and the third pad. The second pad and the third pad are respectively located on both sides adjacent to the first pad. The first pad, the second pad and the third pad are fixed by the frame of the pad bracket, and the frame is made of insulating and high-temperature resistant plastic, such as polyphenylene sulfide (PPS).

[0008] The first pad, the second pad and the third pad on the pad bracket are electrically connected to the positive and negative electrodes corresponding to the voice coil through wires on the side facing the voice coil (called the back side), while the three pads on the side away from the voice coil (called the front side) are exposed to the frame of the pad bracket to facilitate welding of the positive and negative leads when connecting the speaker.

[0009] The polarity of the first pad is opposite to that of the second pad and the third pad, and the second pad and the third pad are connected by a conductive plate, so the polarity of the second pad and the third pad is the same. That is, when the back of the first pad is connected to the positive pole of the voice coil, the front of the first pad leads to the positive pole. At this time, the back of the second pad or the third pad is connected to the negative pole of the voice coil, and the front of the second pad or the third pad leads to the negative pole. Similarly, when the back of the first pad is connected to the negative pole of the voice coil, the front of the first pad leads to the negative pole. At this time, the back of the second pad or the third pad is connected to the positive pole of the voice coil, and the front of the second pad or the third pad leads to the positive pole.

[0010] Since the second pad is connected to the third pad via the conductive plate, at least one of the back surfaces of the second pad and the third pad only needs to be connected to the positive electrode or the negative electrode of the voice coil.

[0011] The beneficial effects of the utility model are:

[0012] The pad bracket of the utility model adopts three pads to facilitate the positive and negative electrodes to be led out from the pads in different directions;

[0013] The second pad and the third pad of the utility model are connected through a conductive plate, and when the second pad or the third pad is damaged and cannot be used for wiring, wiring can still be provided externally through the third pad or the second pad;

[0014] The square speaker using the solder pad bracket of the utility model can lead out the positive and negative electrodes from the short side or the long side, and the second solder pad and the third solder pad can be used selectively. The speaker will not be unable to be connected due to damage to one solder pad, thereby increasing the applicability and life of such speakers. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to fully understand the structure and function of the three pads on the pad bracket in the present technical solution, the following embodiments are listed for specific and detailed description. Example

[0024] The present embodiment provides a loudspeaker, which has a square structure as a whole and is mainly composed of a basin frame 11, a cover plate 12, a vibration plate 13, a magnetic bowl 21, a magnet 22, a pole piece 23, a voice coil 24, a diaphragm 25 and a pad bracket 51. The basin frame 11 is located outside the loudspeaker, and a magnetic bowl 21 is arranged above the basin frame 11, a magnet 22 is arranged above the magnetic bowl 21, and a pole piece 23 is arranged above the magnet 22. The voice coil 24 is located in the gap formed by the magnetic bowl 21, the magnet 22 and the pole piece 23. A diaphragm 25 is arranged around the voice coil 24, and a vibration plate 13 is arranged on the top of the voice coil 24. The cover plate 12 is arranged at the top of the basin frame 11.

[0025] When the voice coil 24 is energized, a magnetic field is generated around the voice coil 24 and interacts with the magnetic field generated by the magnet 22 and the magnetic bowl 21 to form a push-pull force, pushing or pulling the diaphragm 25 to vibrate, resonating with the surrounding air to produce sound.

[0026] A pad bracket 51 is provided at the bottom of the entire speaker. The pad bracket 51 is square and its size fits the shape of the bottom of the speaker basin frame 11. The main components of the pad bracket 51 are composed of pads and conductive plates 27. The pads are divided into a first pad 261, a second pad 262 and a third pad 263, wherein the first pad 261 is independent of the second pad 262 and the third pad 263, and the second pad 262 and the third pad 263 are connected to each other through the conductive plate 27. The conductive plate 27 is made of a metal conductive material, which can realize electrical communication between the second pad 262 and the third pad 263. The second pad 262 and the third pad 263 are respectively located on the adjacent two sides of the first pad 261. The first pad 261, the second pad 262 and the third pad 263 are fixed by the frame of the pad bracket 51, and the frame is made of insulating and high temperature resistant polyphenylene sulfide (PPS) plastic.

[0027] The back of the first pad 261 on the pad support 51 is electrically connected to the positive electrode of the voice coil 24 through a wire, and the back of the second pad 262 or the third pad 263 is electrically connected to the negative electrode of the voice coil 24 through a wire. The fronts of the first pad 261, the second pad 262, and the third pad 263 are exposed relative to the frame of the pad support 51 to facilitate welding of the positive and negative leads when connecting the speaker.

[0028] The first pad 261 is electrically connected to the positive electrode of the voice coil 24, and the second pad 262 and the third pad 263 are electrically connected to the negative electrode of the voice coil 24. The second pad 262 and the third pad 263 are connected via the conductive plate 27, so only one of the second pad 262 and the third pad 263 needs to be electrically connected to the negative electrode of the voice coil 24. That is, the first pad 261 can be combined with the second pad 262 to jointly lead out the positive and negative electrodes of the voice coil 24, and can also be combined with the third pad 263 to jointly lead out the positive and negative electrodes of the voice coil 24.

[0029] It should be noted that, in the present utility model, terms such as "upper", "lower", "front", "back", "bottom" and "top" are all descriptions based on the positional relationship in the drawings of the utility model specification, and are not intended to limit the scope of implementation of the present utility model. Changes or adjustments in their relative relationships, without substantially changing the technical content, should also be regarded as the scope of implementation of the present utility model.
