[0002] A single-unit loudspeaker typically refers to a loudspeaker driver, which is the core component of a loudspeaker system and the key component that converts electrical signals into sound signals. Based on the sound production method, loudspeakers can be classified into moving-coil, inductive, electrostatic, planar, ribbon, and horn types, with moving-coil being the most common. If classified according to the audio frequency processed, there are bass, subwoofer, midrange, tweeter, super tweeter, coaxial, and full-range types. Loudspeakers are widely used in home entertainment, professional audio, and mobile devices, such as home audio systems, mobile phones, computers, smart speakers, and headphones. They can also be used in various electronic devices such as car audio systems, smart toys, and smart audio billboards.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] This embodiment discloses a single-unit application loudspeaker, which aims to solve the problems of sound distortion and inconvenient installation caused by the single cavity of the existing single-unit application loudspeaker. It improves sound quality stability and simplifies the installation process by optimizing the structural design.
[0019] Top cover 1: Can be injection molded from ABS engineering plastic. The top cover 1 has an integrally formed glue application platform 5 in the middle. The glue application platform 5 is a ring-shaped protrusion structure with an inner diameter matching the outer diameter of the monomer 3, which is used to fix the monomer 3 with epoxy resin. The outer edge of the top cover 1 is provided with a mounting platform 6 for fitting with the mounting surface of external equipment. A misalignment groove 7 is also provided between the glue application platform 5 and the inner wall of the top cover 1 to reduce noise caused by sound wave reflection.
[0020] Shell 2: Can be injection molded from PP material, with an inner wall diameter matching the outer diameter of the upper cover 1. The top edge is snapped into place with the bottom of the upper cover 1 using a snap-fit structure. A slot 8 is provided on the inner top side of shell 2 to engage and limit the bottom of the unit 3, such as... Figure 2 As shown;
[0021] Driver 3: A moving-coil midrange speaker driver, model YD100-8, can be selected. Figure 3 As shown, the middle part of the unit 3 is a vibrating diaphragm, and the bottom is a fixed frame. The outer diameter of the frame matches the inner side of the glue application table 5, and the bottom extends into the slot 8 of the housing 2 and engages with the slot 8. The unit 3 has symmetrically arranged wiring pins 9 on both sides. The wiring pins 9 are made of copper, and their outer sides abut against the inner wall of the slot 8. Figure 2 , Figure 3 As shown, it serves both as a limit switch and as an aid in the transmission of electrical signals.
[0022] Terminal 4: Installed on the top side of the inner wall of housing 2, located on one side of unit 3, as shown below. Figure 2 As shown. Its operating function is to connect the external circuit to the wiring pin 9 of unit 3 through a wire to achieve stable transmission of electrical signals and avoid poor contact problems caused by direct wire connection.
[0023] Mounting plate 10: Two mounting plates 10 are symmetrically fixed on both sides of the surface of the upper cover 1. Each mounting plate 10 has through holes such as... Figure 1 As shown, it is used to fix the speaker to an external device, such as an audio housing or a car mount, by means of screws.
[0024] Wire hole 11: Through-hole is formed on the surface of the upper cover 1, located on the top side of the terminal block 4, such as... Figure 2 As shown, it is used to allow external wires to pass through and connect to terminal 4, avoiding wear or messy wiring caused by exposed wires;
[0025] The specific working principle is as follows: First, place monomer 3 inside the glue application table 5 of the upper cover 1, apply epoxy resin glue to the contact surface between the glue application table 5 and monomer 3, and let it stand for 2 hours until the glue cures to achieve the initial fixation of monomer 3 and upper cover 1.
[0026] Align the housing 2 with the top cover 1 from below, so that the bottom of the unit 3 is inserted into the slot 8 of the housing 2, while ensuring that the wiring pins 9 of the unit 3 abut against the inner wall of the slot 8, which serves to limit and assist in conduction. The top cover 1 and the housing 2 are fixed together by the snap-fit structure.
[0027] The terminal block 4 is fixed to the inner wall of the housing 2 with screws, and the input end of the terminal block 4 is soldered to the terminal pin 9 of the unit 3 with a wire.
[0028] The wires of the external device are passed through the wire hole 11 of the upper cover 1 and are fixedly connected to the output end of the terminal block 4 by screws;
[0029] Finally, through the through holes on both sides of the mounting plates 10 of the top cover 1, use screws to fix the entire speaker to the mounting position of the external device to complete the assembly.
[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
