Description

Technical Field

[0001] This utility model relates to the field of irregular-shaped loudspeakers, and in particular to a single loudspeaker with a triangular four-magnet structure. Background Technology

[0002] A loudspeaker is a transducer that converts electrical signals into sound signals, and its performance greatly affects sound quality. The loudspeaker is the weakest component in an audio system, yet it is also one of the most important components for achieving optimal sound effects. There are many types of loudspeakers, and their prices vary greatly. Audio electrical energy, through electromagnetic, piezoelectric, or electrostatic effects, causes the cone or diaphragm to vibrate and resonate with the surrounding air, thus producing sound.

[0003] Smart wearables (such as the ear hooks of glasses) have limited internal space, so existing square or round speakers have poor space utilization when installed on the ear hooks. Therefore, in order to meet the installation requirements of the speakers, the current practice is to design the ear hooks with equal width to achieve the matching of the speakers.

[0004] However, with the arc-shaped design of the ear hooks of smart glasses, existing speakers cannot meet their requirements. For example, Chinese patent 202321850256.2 uses a rectangular speaker to meet the requirements of shape design and space, but its sound quality is greatly affected by its outer diameter. Utility Model Content

[0005] The main purpose of this invention is to propose a single loudspeaker with a triangular four-magnet structure, which aims to improve the existing loudspeaker structure, thereby meeting the design requirements of the ear hook arc shape, while also ensuring relatively stable sound quality.

[0006] To achieve the above objectives, this utility model proposes a single loudspeaker with a triangular four-magnet structure, comprising:

[0007] A dominant magnetic sheet, wherein the diameter of the dominant magnetic sheet gradually decreases from top to bottom;

[0008] The main magnet is shaped to match the main magnetic sheet, and the main magnet and the main magnetic sheet are concentrically arranged. The upper wall of the main magnetic sheet is provided with a main washer.

[0009] Side magnets are provided on both sides of the main magnet along its length. The side magnets have an arc or slope that matches that of the main magnet. A side washer is provided on the upper wall of the side magnets. A first magnetic channel is provided between the side magnets and the main magnet.

[0010] A secondary magnet is located above the main magnet. A secondary washer is provided on the upper wall of the secondary magnet. A second magnetic channel is provided between the secondary magnet and the main magnet.

[0011] A first gap is provided between the two sides of the auxiliary magnet and between the side magnets.

[0012] A second gap is provided between the ends of the side magnets that are away from the auxiliary magnets;

[0013] The first and second magnetic channels form a magnetic flux gap;

[0014] The magnetic flux gap is used to install a voice coil, the shape of which is compatible with the shape of the main magnetic sheet and is concentrically arranged;

[0015] The top of the voice coil is provided with a diaphragm (the diaphragm is mounted on a bracket or set in a spring, which can be set according to actual needs).

[0016] By altering the traditional speaker layout, where the main magnet, side magnets, and auxiliary magnet form a roughly triangular-shaped magnetic circuit assembly for the speaker, the structure of the ear hook arm of smart glasses is thus satisfied.

[0017] This allows for the installation of a large-area speaker within a relatively small space, thus effectively ensuring sound quality while meeting shape requirements.

[0018] The speakers can be either diaphragm speakers or bone conduction speakers, thus meeting different installation and usage requirements.

[0019] This application mainly concerns the magnetic circuit assembly of a loudspeaker, wherein the vibration component and control component can be adjusted according to actual needs or design to achieve the desired acoustic effect. Attached Figure Description

[0037] like Figures 1 to 4 As shown, a single-unit loudspeaker with a triangular four-magnet structure includes:

[0038] A dominant magnetic sheet 1, wherein the diameter of the dominant magnetic sheet 1 gradually decreases from top to bottom;

[0039] The main magnet 11 is adapted to the shape of the main magnetic sheet 1. The main magnet 11 and the main magnetic sheet 1 are concentrically arranged. The upper wall of the main magnetic sheet 1 is provided with a main washer 21.

[0040] Side magnets 12 are provided on both sides of the main magnet 11 along its length. The side magnets 12 have an arc or slope that matches that of the main magnet 11. The upper wall of the side magnets 12 is provided with a side washer 22. A first magnetic channel 31 is provided between the side magnets 12 and the main magnet 11.

[0041] A secondary magnet 13 is located above the main magnet 1. A secondary washer 23 is provided on the upper wall of the secondary magnet 13. A second magnetic channel 32 is provided between the secondary magnet 13 and the main magnet 11.

[0042] A first gap is provided between the two sides of the auxiliary magnet 13 and between the side magnet 12.

[0043] A second gap is provided between the ends of the side magnet 12 that are away from the auxiliary magnet 13;

[0044] The first magnetic channel and the second magnetic channel 32 form a magnetic flux gap;

[0045] The magnetic flux gap is used to install the voice coil 4, the shape of which is compatible with the shape of the main magnetic sheet 1 and is concentrically arranged;

[0046] The top of the voice coil 4 is provided with a diaphragm 40, which is mounted on a bracket or set in a spring, and can be set according to actual needs.

[0047] By altering the traditional speaker layout, the main magnet 11, the two side magnets 12, and the auxiliary magnet 13 form a roughly triangular-shaped magnetic circuit assembly for the speaker, thus satisfying the structural requirements of the ear hook arm for smart glasses.

[0048] This allows for the installation of a large-area speaker within a relatively small space, thus effectively ensuring sound quality while meeting shape requirements.

[0049] The speakers can be either diaphragm speakers or bone conduction speakers, thus meeting different installation and usage requirements.

[0050] Specifically, the main magnet 11 has inclined surfaces 51 on both sides, and the side magnets 12 are inclinedly arranged on both sides of the main magnet 11, which not only meets the shape requirements, but also ensures the consistency of the magnetic flux gap.

[0051] In this embodiment of the present invention, the upper side of the main magnet 11 is a flat surface 52, and the auxiliary magnet 13 is arranged parallel to the flat surface 52.

[0052] Specifically, a first arc angle 61 is provided between the straight surface 52 and the inclined surface 51.

[0053] In this embodiment of the utility model, a second arc angle 62 is provided between adjacent inclined surfaces 51. The setting of the first arc angle 61 and the second arc angle 62 can enable the magnetic flux of the magnet to pass through the magnetic conduction of the main magnetic sheet 1 to form a predetermined magnetic field, thereby enabling the magnetic flux gap and the voice coil 4 to form a predetermined pattern, thereby enabling the control unit to stably realize the sound generation of the diaphragm.

[0054] Specifically, the magnets 12 on both sides are symmetrically arranged.

[0055] In this embodiment of the present invention, a first protrusion 71 is provided on the side of the side washer 22 near the main washer 21.

[0056] Specifically, the secondary washer 23 is provided with a second protrusion 72 on the side near the main washer 21. The arrangement of the first protrusion 71 and the second protrusion 72 can prevent the magnetic flux of the main magnet 11 from expanding outward, thereby realizing the formation of a complete closed loop of magnetic flux, improving the stability of magnetic field tangency, and avoiding the problem of magnetic leakage.

[0057] In this embodiment of the present invention, the two ends of the upper side of the main magnetic sheet 1 are provided with notches 8, thereby satisfying the design of the magnetic field, that is, the magnetic field is located on both sides of the main magnet 11.

[0058] Specifically, the voice coil 4 is elliptical in shape, with one end larger than the other.

[0059] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
