Description

Technical Field

[0001] The present disclosure relates to the field of audio, and in particular to a loudspeaker and an electronic device. Background Art

[0002] With the development of electronic devices towards integration and thinness, due to the size limitation of the electronic devices, the design size of the loudspeakers in the electronic devices is also limited. And for the smaller-sized loudspeakers, due to structural limitations, the loudness of the loudspeakers in the mid-low frequency range is smaller. In the existing loudspeakers, in order to increase the loudness in the mid-low frequency range, a scheme of increasing the magnetic parts is adopted to increase the magnetic induction intensity.

[0055] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all the implementation manners consistent with the present disclosure. On the contrary, they are only examples of speakers and electronic devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0056] In the related art, the magnetic induction intensity of a speaker is increased through the design of three magnetic members or five magnetic members, etc. Figure 1 is a top view of a five-magnetic-circuit speaker shown according to an exemplary embodiment. As Figure 1As shown, in the design of a five-magnetic-circuit speaker, four magnetic members 30 are spaced apart and distributed on four sides of one magnetic member 30, and the voice coil 40 is arranged around one magnetic member 30 provided at the center.

[0057] To further improve the magnetic induction intensity, related technologies have also proposed the design of a six-magnetic-circuit speaker based on the five-magnetic-circuit speaker. Figure 2 It is a side view of a six-magnetic-circuit speaker shown according to an exemplary embodiment. As Figure 2 shown, in the design of a six-magnetic-circuit speaker, the six-magnetic-circuit speaker includes two magnetic members 30 arranged at intervals along the vertical and horizontal directions, and four magnetic members 30 arranged around one of the two magnetic members. Since the added magnetic members increase the thickness of the speaker, the size of the speaker is increased accordingly.

[0058] Based on this, the embodiments of the present disclosure propose a speaker that can reduce the size of the speaker and improve the acoustic performance of the speaker. Figure 3 It is a quarter cross-section of a speaker shown according to an exemplary embodiment Figure 1 . As Figure 3 shown, the speaker includes:

[0059] A support chassis 10;

[0060] A diaphragm 20, connected to the first side of the support chassis 10;

[0061] A plurality of magnetic members 30, spaced apart and arranged on the second side of the support chassis 10 and distributed on the same plane; wherein, the second side is the opposite side of the first side;

[0062] A plurality of voice coils 40, spaced apart and distributed on the diaphragm 20 and located between the magnetic members 30 and the diaphragm 20; wherein, the voice coils 40 can drive the diaphragm 20 to vibrate under the action of the magnetic members 30.

[0063] In the embodiments of the present disclosure, the speaker is used to convert the electrical signal in the electronic device into a sound signal in different scenarios. Exemplarily, in the scenario where the electronic device plays music, the speaker can be used to output the sound signal corresponding to the music; or, when the electronic device realizes the video function, the speaker can be used to output the sound signal corresponding to the video; or, when the electronic device realizes the call function, the speaker can be used to output the sound signal corresponding to the call.

[0064] The above support chassis forms a receiving space, which can be used to receive multiple components such as the diaphragm, a plurality of magnetic members, and a plurality of voice coils, and the support chassis can be used to support the multiple components.

[0065] Among them, the shape of the supporting basin frame includes a groove shape or a ring shape, etc. Exemplarily, when the supporting basin frame is in a groove shape, the supporting basin frame can be a circular groove or an annular groove; when the supporting basin frame is in a ring shape, the supporting basin frame can be a circular ring or a square ring, and the embodiments of the present disclosure do not limit this.

[0066] It should be noted that the supporting basin frame has a first side and a second side that are oppositely arranged. Exemplarily, when the supporting basin frame is in a ring shape, the first side of the supporting basin frame is the side of the first opening, and the second side of the supporting basin frame is the side of the second opening that is oppositely arranged with respect to the first opening.

[0067] Among them, the size of the supporting basin frame can be set according to the actual situation. Exemplarily, when the supporting basin frame is in a circular ring shape, the diameter of the supporting basin frame can be in the range of 25 millimeters to 35 millimeters, and the thickness of the supporting basin frame can be in the range of 1.3 millimeters to 1.5 millimeters, and the embodiments of the present disclosure do not limit this.

[0068] The above-mentioned diaphragm is connected to the first side of the supporting basin frame, that is, the edge of the diaphragm is fixed at the edge of the supporting basin frame to ensure that the diaphragm can transmit sound signals when vibrating.

[0069] Among them, the diaphragm needs to be made of an elastic material. Exemplarily, the material of the diaphragm includes polyester fiber or carbon fiber composite material, etc., and the embodiments of the present disclosure do not limit this.

[0070] It should be noted that the sizes of the diaphragm and the supporting basin frame need to match each other to improve the vibration effect of the diaphragm. Here, the sizes of the diaphragm and the supporting basin frame matching each other can include: the shape of the diaphragm is similar to or the same as the shape of the first opening of the supporting basin frame; and / or, the area of the first opening of the supporting basin frame is equal to the area of the diaphragm, and the embodiments of the present disclosure do not limit this.

[0071] The above-mentioned multiple magnetic members can include multiple magnetic members with different shapes. Exemplarily, the shape of the magnetic member includes a rectangle, a circle or a ring, etc. Here, the magnetic members can also include different numbers. Exemplarily, the number of magnetic members includes three, four or five, etc.

[0072] Among them, the magnetic member is made of a magnetic material. Exemplarily, the material of the magnetic member includes a neodymium iron boron magnet, which is used to provide a magnetic field for the voice coil and then drive the voice coil to move based on the magnetic force of the magnetic field.

[0073] In the embodiments of the present disclosure, the multiple magnetic members are arranged at intervals on the second side of the supporting basin frame, and the interval between two adjacent magnetic members can be set according to the needs of the magnetic field distribution. Exemplarily, the intervals between the multiple magnetic members include a first interval and a second interval, and the first interval and the second interval can be equal or unequal, and the embodiments of the present disclosure do not limit this.

[0074] It should be noted that multiple magnetic components are distributed on the same plane. Here, the plane on which the multiple magnetic components are distributed is parallel to the plane where the diaphragm is located. In this way, the plane where the voice coil is distributed on the diaphragm is also parallel to the plane where the magnetic components are located, which can ensure that the magnetic induction lines of the voice coil and the magnetic components are perpendicular, so that the voice coil can vibrate better based on the magnetic force of the magnetic field.

[0075] The shapes of the multiple voice coils described above can be set according to actual situations. Exemplarily, the multiple voice coils can be set as annular. Among them, the multiple voice coils can be square annular or circular annular, etc. Here, the number of voice coils can also be set differently according to the size of the diaphragm. Exemplarily, the number of voice coils includes three, four, or five, etc.

[0076] It should be noted that in the case where the multiple voice coils are annular, the sizes of the multiple voice coils can increase in sequence, and two adjacent voice coils are nested. Here, the interval between two adjacent voice coils can be set according to the size of the diaphragm. Exemplarily, the intervals between the multiple voice coils include a third interval and a fourth interval, and the third interval and the fourth interval can be equal or unequal. The embodiments of the present disclosure do not limit this.

[0077] The multiple voice coils described above can drive the diaphragm to vibrate under the action of the multiple magnetic components. It can be understood that when the current passing through the voice coils is the same, the vibration amplitude and vibration frequency of each voice coil are the same. In this way, the vibration amplitude and frequency of each part of the diaphragm connected to the voice coil can be the same, improving the vibration accuracy of the diaphragm, and thus improving the acoustic performance of the speaker.

[0078] In the embodiments of the present disclosure, since the multiple voice coils are composed of conductive coils, each voice coil includes one or more turns of conductive coils. When the speaker receives an electrical signal, current will pass through the conductive coils. According to the principle of electromagnetic induction, a magnetic field will be generated around the voice coil. In this way, the magnetic field of the voice coil and the magnetic field of the magnetic component interact with each other. According to the principle of the Lorentz force, the force that the current receives in the magnetic field causes the voice coil to vibrate. Also, since the voice coils are spaced apart and distributed on the diaphragm, the vibration of the voice coil drives the diaphragm to vibrate to emit a sound signal.

[0079] It should be noted that the formula for the magnetic force F that the voice coil receives in the magnetic field is formula (1):

[0080] F = B × L × I (1)

[0081] Among them, B is the magnetic induction intensity of the magnetic field, I is the magnitude of the current in the conductive coil, and L is the length of the conductive coil.

[0082] In the embodiments of the present disclosure, the voice coil is disposed between the magnetic member and the diaphragm, so that the partial accommodation space between the magnetic member and the diaphragm can be utilized to increase the width of the conductive coil in the voice coil. Since the width of the conductive coil is proportional to the magnitude of the current, and it can be obtained from formula (1) that the magnitude of the current in the conductive coil is proportional to the magnetic force. Therefore, the wider the width of the conductive coil in the voice coil, the greater the current in the conductive coil, and the greater the magnetic force exerted on the voice coil in the magnetic field. Thus, increasing the width of the voice coil can improve the acoustic performance of the speaker.

[0083] Similarly, the number of voice coils is proportional to the magnitude of the magnetic force. Exemplarily, the magnetic forces received by multiple voice coils are greater than those received by a single voice coil.

[0084] In the embodiments of the present disclosure, multiple voice coils of the speaker are disposed on the diaphragm, and the magnetic force generated by the magnetic member is used to drive the voice coil to drive the diaphragm to vibrate, enabling the speaker to emit sound. Moreover, in the speaker of the embodiments of the present disclosure, multiple magnetic members and multiple voice coils are provided. The multiple magnetic members can increase the magnetic flux of the magnetic field, and the multiple voice coils can increase the length of the voice coils located in the magnetic field, thereby increasing the magnetic force exerted on the voice coils under the action of the magnetic field and improving the acoustic performance of the speaker. Also, the multiple magnetic members of the speaker are located in the same plane, reducing the thickness of the speaker and thus reducing the size of the speaker.

[0085] In some embodiments, the projection of the gap between two adjacent magnetic members onto the diaphragm at least partially coincides with one voice coil, and the magnetic forces generated by the two adjacent magnetic members can drive the corresponding voice coil to drive the diaphragm to vibrate.

[0086] That is to say, one voice coil corresponds to two adjacent magnetic members, and under the magnetic forces generated by the two adjacent magnetic members, the corresponding voice coil can be driven to vibrate, and then the vibrating voice coil can drive the diaphragm to vibrate to emit sound.

[0087] Exemplarily, the magnetic member includes a first magnetic member, a second magnetic member, and a third magnetic member, and the voice coil includes a first voice coil and a second voice coil; the second magnetic member is located between the first magnetic member and the third magnetic member.

[0088] Here, the projection of the gap between the first magnetic member and the second magnetic member onto the diaphragm at least partially coincides with the first voice coil, and the magnetic fields generated by the first magnetic member and the second magnetic member can interact with the magnetic field of the first voice coil to generate a first magnetic force, and then this first magnetic force can drive the first voice coil to vibrate.

[0089] Here, the projection of the gap between the second magnetic member and the third magnetic member onto the diaphragm at least partially coincides with the second voice coil, and the magnetic fields generated by the second magnetic member and the third magnetic member can interact with the magnetic field of the second voice coil to generate a second magnetic force, and then the second magnetic force can drive the second voice coil to vibrate.

[0090] It can be understood that the second magnetic member can generate a first magnetic force for the vibration of the first voice coil and a second magnetic force for the vibration of the second voice coil. In this way, the space utilization rate of the magnetic member is improved, and the size of the speaker is reduced.

[0091] In the embodiments of the present disclosure, the projection of the gap between two adjacent magnetic members on the diaphragm at least partially coincides with a voice coil, including that the projection of the gap between two adjacent magnetic members on the diaphragm completely coincides with a voice coil and the projection of the gap between two adjacent magnetic members on the diaphragm partially coincides with a voice coil.

[0092] Wherein, the projection of the gap between two adjacent magnetic members on the diaphragm is the first projection, and the projection of the voice coil on the diaphragm is the second projection. When the projection of the gap between two adjacent magnetic members on the diaphragm completely coincides with a voice coil, the area of the first projection is greater than or equal to the area of the second projection; when the projection of the gap between two adjacent magnetic members on the diaphragm partially coincides with a voice coil, the area of the first projection may be equal to or different from the area of the second projection, and the embodiments of the present disclosure do not limit this.

[0093] It should be noted that since the magnetic fields generated by two adjacent magnetic members have closed magnetic induction lines to ensure that the magnetic field can be transmitted and generate a magnetic force that interacts with the magnetic field of the corresponding voice coil.

[0094] In the embodiments of the present disclosure, by setting the voice coil corresponding to the gap between two adjacent magnetic members, the voice coil can be better located in the magnetic field generated by two adjacent magnetic members, improving the acoustic performance of the speaker.

[0095] In some embodiments, a plurality of magnetic members are arranged in a preset direction, and the magnetic poles of two adjacent magnetic members facing the voice coil side are opposite.

[0096] In the embodiments of the present disclosure, the layout of a plurality of magnetic members can be set according to the actual situation. Exemplarily, when a plurality of magnetic members are annular magnetic members and a plurality of annular magnetic members are nested, the plurality of annular magnetic members are arranged along the radius extension line direction of the center of the annular magnetic member; when a plurality of magnetic members are square magnetic members and a plurality of square magnetic members are spaced apart, the plurality of square magnetic members are arranged along the length direction of the square magnetic member, and / or the plurality of magnetic members are arranged along the width direction of the magnetic member, and the embodiments of the present disclosure do not limit this.

[0097] In the embodiments of the present disclosure, the magnetic member includes a first side facing the voice coil and a second side facing away from the voice coil, and two adjacent magnetic members include a first magnetic member and a second magnetic member.

[0098] Among them, the magnetic poles on the first side and the second side of the magnetic member are opposite. Exemplarily, when the magnetic pole on the first side of the magnetic member is the south pole, the magnetic pole on the second side of the magnetic member is the north pole.

[0099] The magnetic poles of the adjacent two magnetic members facing the voice coil side are opposite. Exemplarily, the magnetic pole on the first side of the first magnetic member is the south pole, and the magnetic pole on the first side of the second magnetic member is the north pole; or, the magnetic pole on the first side of the first magnetic member is the north pole, and the magnetic pole on the first side of the second magnetic member is the south pole.

[0100] It should be noted that since the magnetic induction line direction of the magnetic member points from the south pole to the north pole, when the magnetic poles of the adjacent two magnetic members facing the voice coil side are opposite, the magnetic fields between the two magnetic members are connected to form a closed loop. Exemplarily, the magnetic induction lines of the south pole on the first side of the first magnetic member point to the north pole on the first side of the second magnetic member, and the south pole on the second side of the second magnetic member points to the north pole on the second side of the first magnetic member. In this way, after the voice coil receives an electrical signal, it will receive a more uniform magnetic force in the magnetic field, making the amplitude of the vibration of the voice coil more uniform.

[0101] In the embodiments of the present disclosure, by designing the magnetic pole directions of the adjacent two magnetic members, the distribution of the magnetic field is optimized, so that the magnetic force received by the voice coil is more uniform, the vibration amplitude of the voice coil is more uniform, and further the amplitude of the vibration of the diaphragm driven by the voice coil is more uniform, thereby improving the acoustic performance of the speaker.

[0102] In some embodiments, Figure 4 is a cross-section of a quarter speaker shown according to an exemplary embodiment Figure 2 , as Figure 4 shown, the speaker further includes:

[0103] A plurality of first magnetic conduction members 501 arranged at intervals;

[0104] The first magnetic conduction member 501 is located on the side of the magnetic member 30 facing the diaphragm, and one first magnetic conduction member 501 is arranged on one magnetic member 30.

[0105] In the embodiments of the present disclosure, the projection of the gap between the adjacent two first magnetic conduction members on the diaphragm at least partially coincides with the projection of the gap between the adjacent two magnetic members on the diaphragm. Here, the shape of the projection of the gap between the adjacent two first magnetic conduction members on the diaphragm and the projection of the gap between the adjacent two magnetic members on the diaphragm may be the same or different; the area of the projection of the gap between the adjacent two first magnetic conduction members on the diaphragm and the projection of the gap between the adjacent two magnetic members on the diaphragm may be equal or unequal, and the embodiments of the present disclosure do not limit this.

[0106] Among them, the first magnetic guiding member is made of a magnetic material. Exemplarily, the material of the first magnetic guiding member includes iron or ferrite, and the embodiments of the present disclosure do not limit this.

[0107] The above-mentioned first magnetic guiding member is located on the side of the magnetic member facing the diaphragm, and is used to guide and concentrate the magnetic field of the magnetic member corresponding to the first magnetic guiding member, so that the magnetic field of the voice coil and the magnetic field of the magnetic member can more easily generate a magnetic acting force on the voice coil.

[0108] It should be noted that one first magnetic guiding member is arranged on one magnetic member, that is, the number of first magnetic guiding members is equal to the number of magnetic members. Exemplarily, when the number of magnetic members is four, four first magnetic guiding members are also arranged. In this way, it can be ensured that each magnetic member can be affected by the magnetic field of the magnetic member by the first magnetic guiding member, and further each voice coil can be better affected by the magnetic acting force to vibrate and drive the diaphragm to vibrate.

[0109] In the embodiments of the present disclosure, since the first magnetic guiding member is arranged on the magnetic member, the voice coil is arranged at intervals between the magnetic member and the diaphragm, and the projection of the gap between two adjacent magnetic members on the diaphragm at least partially coincides with one voice coil. It can be understood that one voice coil also corresponds to the gap between two adjacent first magnetic guiding members.

[0110] Among them, the projection of the gap between two adjacent first magnetic guiding members on the diaphragm at least partially coincides with one voice coil. Here, a projection area is formed by the projection of the gap between two adjacent first magnetic guiding members on the diaphragm. When the projection of the voice coil on the diaphragm is entirely located within the projection area, at least a part of the voice coil is located in the gap between two adjacent first magnetic guiding members during vibration; when the projection of the voice coil on the diaphragm is partially located within the projection area, the voice coil is located between the first magnetic guiding member and the diaphragm during vibration.

[0111] It should be noted that the voice coil is arranged at intervals from the first magnetic guiding member during the vibration process, so that the voice coil does not contact the first magnetic guiding member during vibration, thereby reducing the noise generated when the voice coil touches the first magnetic guiding member.

[0112] In the embodiments of the present disclosure, the first magnetic guiding member and the magnetic member can be directly connected or indirectly connected. Exemplarily, the first magnetic guiding member can be adsorbed on the magnetic member by magnetic acting force; or, the first magnetic guiding member and the magnetic member can be connected through an adhesive layer, and the embodiments of the present disclosure do not limit this.

[0113] Among them, the area of the connection surface where the first magnetic guiding member is connected to the magnetic member and the area of the connection surface where the magnetic member is connected to the first magnetic guiding member can be equal or unequal, and the embodiments of the present disclosure do not limit this.

[0114] Exemplarily, in some embodiments, the first magnetic conductive member has a first connection surface connecting the corresponding magnetic member; the magnetic member has a second connection surface connecting the corresponding first magnetic conductive member; the area of the first connection surface is less than or equal to the area of the second connection surface. In this way, the first magnetic conductive member does not block the gap between two adjacent magnetic members, thereby reducing the influence on the magnetic field formed between two adjacent magnetic members.

[0115] In the embodiments of the present disclosure, the arrangement of the first magnetic conductive member not only helps to optimize the magnetic field distribution of the magnetic member, but also enables more precise tuning by setting the number and position of the first magnetic conductive member. Furthermore, through the interaction between the first magnetic conductive member and the magnetic member, the influence of the magnetic field of the magnetic member on the voice coil is improved, so as to improve the acoustic performance of the speaker.

[0116] In some embodiments, the plurality of magnetic members include a central magnetic member and a plurality of annular magnetic members;

[0117] The central magnetic member is located at the center of the circle of the plurality of annular magnetic members, and two adjacent annular magnetic members among the plurality of annular magnetic members are nested.

[0118] The above-mentioned central magnetic member is located at the center of the circle of the plurality of annular magnetic members, and two adjacent annular magnetic members among the plurality of annular magnetic members are nested. It can be understood that the plurality of annular magnetic members are concentric rings.

[0119] It should be noted that the central magnetic member is located at the center position of the circle. It can be that the center of the central magnetic member coincides with the center of the circle of the plurality of annular magnetic members, or the center of the central magnetic member is located between the center of the circle and the annular magnetic member. When the center of the central magnetic member coincides with the center of the circle of the plurality of annular magnetic members, it can ensure that the magnetic field can be formed at the center of the speaker, making the sound emission effect of the speaker more uniform and the sound emission position more accurate.

[0120] Two adjacent annular magnetic members among the above-mentioned plurality of annular magnetic members are nested, that is, the inner side of one annular magnetic member surrounds the outer side of another annular magnetic member. Since the two adjacent annular magnetic members are nested, the magnetic fields in the gaps formed between the two annular magnetic members will affect each other, which helps to form a more uniform and concentrated magnetic field.

[0121] Among them, the nested plurality of annular magnetic members make full use of the magnetic field of the intermediate magnetic member. Exemplarily, the annular magnetic members include a first annular magnetic member, a second annular magnetic member, and a third annular magnetic member with gradually increasing circumferences. Here, the side of the second annular magnetic member facing the first annular magnetic member can form a magnetic field that generates a magnetic force on the voice coil with the first annular magnetic member, and the side of the second annular magnetic member facing the third annular magnetic member can form a magnetic field that generates a magnetic force on the voice coil with the third annular magnetic member.

[0122] It is understandable that arranging multiple annular magnetic members around the central magnetic member can generate more and more uniform magnetic fields compared to having only one annular magnetic member around the central magnetic member. In this way, the magnetic force acting on the voice coil can be increased, so that the loudspeaker can generate more accurate and high-quality sound signals.

[0123] In the embodiments of the present disclosure, the shapes of the central magnetic member and the annular magnetic member can be the same or different. Exemplarily, for the case where the shapes of the central magnetic member and the annular magnetic member are different, in some embodiments, the central magnetic member includes a circular magnetic member, and the annular magnetic member includes a square annular magnetic member; or, the central magnetic member includes a square magnetic member, and the annular magnetic member includes a circular annular magnetic member.

[0124] For the case where the shapes of the central magnetic member and the annular magnetic member are the same, in some embodiments, the central magnetic member includes a circular magnetic member, and the annular magnetic member includes a circular annular magnetic member; or, the central magnetic member includes a square magnetic member, and the annular magnetic member includes a square annular magnetic member.

[0125] It should be noted that the shape of the central magnetic member corresponds to the shape of the annular magnetic member, so that the gap between adjacent two magnetic members is more uniform. In this way, the magnetic field between adjacent two magnetic members is more uniform, and further the voice coil receives more uniform magnetic force in the magnetic field.

[0126] In the embodiments of the present disclosure, through the arrangement of the central magnetic member and the annular magnetic member, multiple magnetic fields are formed by making full use of the magnetic poles on different sides of the magnetic member to increase the magnetic force acting on the voice coil, so that the voice coil can better drive the diaphragm to vibrate, and further improve the acoustic performance of the loudspeaker.

[0127] In some embodiments, as Figure 4 shown, the loudspeaker further includes:

[0128] A second magnetic conduction member 502, connected to the second side of the support chassis 10;

[0129] [[ID=Z4]]A plurality of the magnetic members 30 are spaced apart and distributed on the side of the second magnetic conduction member 502 facing the diaphragm.

[0130] In the embodiments of the present disclosure, the second magnetic conduction member can be one or more. Exemplarily, when the second magnetic conduction member is multiple, one second magnetic conduction member corresponds to one magnetic member, and the magnetic members are all distributed on the side of the second magnetic conduction member facing the diaphragm; when the second magnetic conduction member is one, a plurality of magnetic members are spaced apart and distributed on the side of the second magnetic conduction member facing the diaphragm.

[0131] Among them, the second magnetic conduction member is made of a magnetic conductive material. Exemplarily, the material of the second magnetic conduction member includes iron or ferrite, and the embodiments of the present disclosure do not limit this.

[0132] In the embodiments of the present disclosure, when there is only one second magnetic member, the second magnetic member can be arranged in a sheet shape. When the support basin frame is annular, the sheet-shaped second magnetic member is located on the second side of the support basin frame. In this way, the second magnetic member can not only concentrate the magnetic field for the magnetic member, but also serve as the bottom of the accommodating space of the support basin frame for placing the magnetic member.

[0133] It should be noted that the magnetic member is located on the side of the second magnetic member facing the diaphragm, that is, the magnetic member is located between the first magnetic member and the second magnetic member. In this way, the second magnetic member can cooperate with the first magnetic member to guide the magnetic field of the magnetic member, so that the magnetic field of the magnetic member acts on the voice coil on the diaphragm intensively, which can increase the magnetic force on the voice coil and thus improve the vibration effect of the diaphragm.

[0134] In the embodiments of the present disclosure, the setting of the second magnetic member can optimize the magnetic field distribution of the magnetic member, so as to optimize the propagation of sound signals, and further optimize the acoustic performance of the speaker, especially the propagation of mid-low frequency sound signals.

[0135] In some embodiments, the support basin frame is an annular basin frame;

[0136] The diaphragm covers the first opening of the annular basin frame;

[0137] The second magnetic member at least partially covers the second opening of the annular basin frame;

[0138] The second opening and the first opening are two opposite openings of the annular basin frame.

[0139] In the embodiments of the present disclosure, the shape of the annular basin frame can be set according to actual situations. Exemplarily, the annular basin frame can be a circular annular basin frame or a square annular basin frame, and the embodiments of the present disclosure do not limit this.

[0140] The above diaphragm covers the first opening of the annular basin frame, that is, the area of the diaphragm is greater than or equal to the cross-sectional area at the first opening. In this way, it is ensured that the diaphragm can better transmit sound signals when vibrating.

[0141] Among them, the edge of the diaphragm can be fixed at different positions of the annular basin frame. Exemplarily, the edge of the diaphragm can be fixed on the inner wall at the first opening of the annular basin frame; or, the edge of the diaphragm can be fixed on the side adjacent to the inner wall of the annular basin frame; or, the edge of the diaphragm can be fixed on the outer wall opposite to the inner wall of the annular basin frame, and the embodiments of the present disclosure do not limit this.

[0142] The above second magnetic member at least partially covers the second opening of the annular basin frame, that is, the area of the second magnetic member and the area of the second opening can be equal or unequal.

[0143] Among them, the second magnetic conductive member and the annular basin frame can be directly connected or indirectly connected. Exemplarily, the second magnetic conductive member can be connected to the annular basin frame by an adhesive; alternatively, the second magnetic conductive member is connected to the annular basin frame through a connecting member.

[0144] In the embodiments of the present disclosure, the interaction among the annular basin frame, the diaphragm and the second magnetic conductive member helps to improve the structural stability of the speaker, thereby enabling the speaker to achieve clear and high-quality sound signal transmission.

[0145] In some embodiments, the speaker further includes a connecting member for connecting the supporting basin frame and the second magnetic conductive member;

[0146] The connecting member is disposed on the supporting basin frame; or,

[0147] The connecting member is disposed on the second magnetic conductive member; or,

[0148] The connecting member includes a first engaging member and a second engaging member that are engaged with each other. The first engaging member is disposed on the supporting basin frame, and the second engaging member is disposed on the second magnetic conductive member.

[0149] In the embodiments of the present disclosure, Figure 5a is a bottom view of a speaker shown according to an exemplary embodiment. As Figure 5a shown, the connecting member 60 can be a connecting protrusion extending on the second magnetic conductive member 502, and the connecting protrusion is used to buckle the edge of the supporting basin frame 10; or, the connecting member can be a connecting protrusion extending on the supporting basin frame, and the connecting protrusion is used to buckle the second magnetic conductive member.

[0150] In the embodiments of the present disclosure, the connecting member further includes a first engaging member and a second engaging member that are engaged with each other.

[0151] Among them, the first engaging member may include a first card hole or a first buckle, and the second engaging member also includes a first card hole or a first buckle. When the first engaging member is a first card hole, the second engaging member corresponds to a first buckle; when the first engaging member is a first buckle, the second engaging member corresponds to a first card hole.

[0152] Exemplarily, a first card hole is formed on the supporting basin frame; the second engaging member forms a first buckle on the side facing the first engaging member; the first buckle is engaged in the first card hole.

[0153] In the embodiments of the present disclosure, the supporting basin frame in the speaker is connected to the second magnetic conductive member through a connecting member, which can make the structure of the speaker more stable.

[0154] In some embodiments, the speaker further includes:

[0155] An adhesive member for adhering the diaphragm and the voice coil and adhering the diaphragm and the supporting basin frame.

[0156] In the embodiments of the present disclosure, the voice coil is used to carry current and generate a magnetic force in a magnetic field to drive the diaphragm to vibrate. The diaphragm is used to vibrate to generate a pressure change in the air, thereby generating a sound signal. The bonding member bonds the diaphragm and the voice coil, which is the basis for the voice coil to drive the diaphragm to vibrate, so as to ensure that the speaker can output a sound signal.

[0157] Similarly, the supporting chassis is used to provide fixation and support for the diaphragm. The bonding member bonds the diaphragm and the supporting chassis, ensuring that the diaphragm remains connected to the supporting chassis during vibration, thereby ensuring that the diaphragm can generate a sound signal.

[0158] Among them, the bonding member can be made of a high-strength and wear-resistant bonding material. Exemplarily, the materials of the bonding member include: epoxy resin, polyurethane, silicone rubber, etc., and the embodiments of the present disclosure do not limit this.

[0159] In the embodiments of the present disclosure, by bonding the diaphragm and the voice coil and bonding the diaphragm and the supporting chassis with the bonding member, the firm connection between each component is ensured, the structural stability of the speaker is improved, and further the quality and stability of the sound signal transmitted by the speaker are improved.

[0160] For a better understanding of the above one or more embodiments, the embodiments of the present disclosure are exemplified as follows:

[0161] Figure 5b is a top view of a speaker shown according to an exemplary embodiment. Figure 6 is an exploded view of the structure of a speaker shown according to an exemplary embodiment. As Figure 6 shown, the speaker includes: a supporting chassis 10, a diaphragm 20, a magnetic member 30, a voice coil 40, a first magnetic conduction member 501, and a second magnetic conduction member 502. Among them, the diaphragm 20 further includes a surround 201 and a diaphragm 202. The above-mentioned supporting chassis is a circular chassis, having a first opening facing the diaphragm and a second opening facing the second magnetic conduction member. The supporting chassis forms a receiving space for receiving the magnetic member, the first magnetic conduction member, and the voice coil.

[0162] The above-mentioned diaphragm includes a surround and a diaphragm. As Figure 5b shown, the surround is fixed at the edge of the first opening of the supporting chassis and covers the edge of the supporting chassis. The diaphragm is a metal thin film. The diaphragm is pasted at the central position of the surround. The diaphragm is used to vibrate and transmit sound signals under the drive of the voice coil.

[0163] The above-mentioned magnetic member is provided with a circular central magnetic member and three circular magnetic members. Among them, the circumference of the circular magnetic member closer to the circular central magnetic member is shorter. Here, the four magnetic members are arranged at intervals and the magnetic poles of two adjacent magnetic members on the side facing the voice coil are opposite. The magnetic member is used to generate a magnetic field acting on the voice coil.

[0164] The first magnetic conductive member is provided with four first magnetic conductive members corresponding to the magnetic member. Each first magnetic conductive member has the same shape as the corresponding magnetic member, and the area of the connecting surface between the first magnetic conductive member and the magnetic member is smaller than the area of the connecting surface between the magnetic member and the first magnetic conductive member. The first magnetic conductive member is used to further concentrate the magnetic field of the magnetic member.

[0165] The second magnetic conductive member is arranged at the second opening of the support frame. Figure 5a As shown, the second magnetic conductive member is a circular plate with four connecting protrusions formed around its circumference. These protrusions are designed to snap onto the outer wall of the support frame, securing the second magnetic conductive member to the support frame. The second magnetic conductive member serves as the base of the support frame for the magnetic component and can also be used to further concentrate the magnetic field of the magnetic component.

[0166] The voice coil configuration includes three annular voice coils, located between the magnetic element and the diaphragm. One voice coil overlaps the projection of the diaphragm onto the gap between two adjacent magnetic elements. This allows the magnetic field generated by the voice coil when receiving an electrical signal to interact with the magnetic field of the magnetic element, generating a magnetic force that drives the diaphragm to vibrate.

[0167] It should be noted that the voice coil has a cross-section perpendicular to the plane of the diaphragm, and the extension of the intersection of the voice coil cross-section and the diaphragm passes through the center of the diaphragm. It is understandable that the circumference of a voice coil located farther from the central magnetic element is greater than that of a voice coil located closer to the central magnetic element. The shorter the circumference of the voice coil, the smaller the current passing through it. Therefore, a shorter voice coil circumference and a larger cross-sectional area increase the current passing through the voice coil, thereby increasing the magnetic force acting on the voice coil.

[0168] Figure 7 FIG. 4 is a schematic diagram of a loudspeaker magnetic field according to an exemplary embodiment. Figure 8 FIG. 1 is a diagram showing the relationship between the voice coil position and the magnetic induction intensity according to an exemplary embodiment. Figure 8 As shown in the figure, the X-axis is the displacement distance of the voice coil when it vibrates, and the Y-axis is the magnetic induction intensity B.

[0169] In the disclosed embodiments, the speaker is positioned in a rectangular coordinate system, with the speaker's center point as the origin. The speaker's bottom lies on the plane formed by the XY axes, with the Z axis at zero. The speaker's thickness is then defined as its length in the Z-axis direction. It is understood that the speaker's Z-axis thickness can be reduced to half that of a six-magnetic-circuit speaker, while the magnetic induction intensity is greater than that of a five-magnetic-circuit speaker and similar to that of a six-magnetic-circuit speaker. Therefore, the speaker of the disclosed embodiments can reduce its size while improving its acoustic performance.

Here, the series connection of the plurality of voice coils can increase the overcurrent capacity of the loudspeaker and the wiring is simple.

[0181] Or, the leads of the plurality of voice coils can also be connected in parallel to the audio port, that is, the leads of the voice coils are all connected to the audio port to form a parallel circuit. Here, the parallel connection of the plurality of voice coils can increase the current magnitude of the voice coil to increase the magnetic force received by the voice coil.

[0182] In the embodiments of the present disclosure, the series or parallel connection of the voice coil and the audio port can be selected according to the actual situation, which improves the flexibility of the speaker design and can also meet the output requirements of the sound signals of different electronic devices.
