TECHNICAL FIELD
[0001] The utility model relates to gamepad technical field especially relates to a gamepad sound production motor's sound amplification structure. BACKGROUND
[0002] In the current gamepad market, the vibration motor is an important part of enhancing the game experience of players, usually installed in the handle part of the gamepad, to provide vibration feedback, so that the players are more immersed in the game scene. However, a large number of game players feedback that the sound produced by the existing gamepad vibration motor during work is too small, which makes it difficult for players to fully feel the strong feedback brought by vibration during the game process, and they cannot better integrate into the game situation, which affects the integrity and immersion of the game experience to some extent.
[0003] At present, if electronic loudspeakers are used to enhance the sound effect, although the volume can be significantly improved, the production cost of the gamepad will be greatly increased, which is not conducive to the market competitiveness and popularization and promotion of the product. At present, it is urgent to design a scheme that can effectively expand the vibration sound of the vibration motor through structural optimization, so as to meet the needs of players for stronger vibration feedback and control the cost.
[0004] Therefore, it is an urgent problem for those skilled in the art to develop a gamepad sound production motor sound amplification structure. UTILITY MODEL CONTENT
[0005] The utility model provides a gamepad sound production motor sound amplification structure, which effectively expands the sound of the vibration motor without the help of electronic loudspeakers, improves the game experience of players, and controls the cost.
[0006] The above-mentioned purpose of the utility model is realized by the following technical scheme: a gamepad sound production motor sound amplification structure, comprising a vibration motor installed inside the gamepad shell, a resonance cavity is arranged outside the vibration motor, which is used to collect and amplify the sound produced by the vibration motor, the resonance cavity is provided with a loudspeaker opening outwardly facing the gamepad shell, and the gamepad shell is provided with a sound hole at a position corresponding to the loudspeaker opening for sound propagation.
[0007] Resonance cavity and horn: the resonance cavity is used to collect the sound produced by the vibration motor and amplify the sound through the principle of resonance. The unique horn shape of the horn can further amplify the sound and direct the sound to a specific direction. The resonance cavity and its horn are manufactured by an integrated molding process. This design has multiple advantages. On the one hand, during the production process, the assembly process of multiple parts manufactured separately is reduced, greatly simplifying the manufacturing process and improving production efficiency. On the other hand, integrated molding reduces the cost of connecting materials and processes between parts, effectively reducing production costs. At the same time, the integrated structure is more stable, reducing energy loss and leakage during sound propagation, which helps to improve the sound amplification effect.
[0008] Reflection structure: the resonance cavity is provided with a reflection structure for concentrating and reflecting the sound emitted by the vibration motor to the direction of the horn. The reflection structure can be a reflection plane or a reflection surface. Through the design of the angle and shape of the reflection surface, directional propagation and focusing of sound are achieved.
[0009] Vibration motor: the vibration motor can be a linear motor or an eccentric motor, which is determined according to the overall design requirements and performance requirements of the gamepad. It serves as the sound source and provides the vibration basis for the entire sound amplification structure.
[0010] Sound hole: the sound hole on the gamepad shell is circular with a diameter of 2mm and is uniformly distributed in a circular array. This design ensures smooth sound propagation to the outside and effectively prevents dust and moisture from entering the handle and affecting device performance.
[0011] The advantages of the present utility model compared with the prior art are:
[0012] 1. Enhance sound effect: through the synergistic effect of the resonance cavity and the sound reflection structure, the sound of the vibration motor is effectively amplified, so that the player can clearly and strongly feel the vibration feedback, greatly improving the game immersion.
[0013] 2. Cost control: without adding electronic speakers and other high-cost components, sound amplification is achieved through structural design, reducing production costs and improving product market competitiveness.
[0014] 3. Simple structure: the entire sound amplification structure is simple and easy to produce, manufacture and install, without increasing the manufacturing difficulty and complexity of the gamepad. BRIEF DESCRIPTION OF DRAWINGS

[0022] The utility model is further described in detail below in connection with the drawings.
[0023] Embodiment one: as Figure 1 , Figure 2 and Figure 3 Indicated, a gamepad sound generating motor's sound amplification structure, including the linear motor 2 (vibration motor) of installing in the gamepad shell 1 inside, the linear motor 2 is installed in the handle inside close to the side of holding position, so that the player more intuitively feels vibration. The linear motor 2 outside is provided with the resonance cavity 3, for collecting and amplifying the sound generated by the linear motor 2, the resonance cavity 3 is equipped with the loudspeaker mouth 4 outward to the gamepad shell 1, adopts high toughness plastic through injection molding process, makes the resonance cavity 3 and the gamepad shell 1 integral molding. This way not only simplifies the production process, also reduces the connecting gap between parts, reduces the possibility of sound leakage. Utilize the high precision characteristics of injection molding process, ensure that the shape and size of the resonance cavity 3 meet the acoustic design requirements, can effectively collect and amplify vibration sound. The loudspeaker mouth 4 and the resonance cavity 3 are synchronously formed in the injection molding process, ensure that the connection is tight, and the sound transmission is smooth.
[0024] The gamepad shell 1 is provided with the circular sound hole 5 with the diameter of 2mm at the position corresponding to the loudspeaker mouth 4, and is uniformly distributed according to circular array, and the spacing between the sound hole 5 is calculated to ensure the uniformity and definition of sound propagation.
[0025] A reflective plane 6 is arranged inside the resonance cavity 3 as a reflective structure. The reflective plane 6 is arranged obliquely inside the resonance cavity 3, and the reflective plane 6 is integrally formed with the gamepad shell 1, the resonance cavity 3, and the horn mouth 4. A plurality of reflective planes 6 are arranged in a ring around the linear motor 2, and the angle and position between each reflective plane 6 are accurately calculated to ensure that the sound emitted by the linear motor 2 can be reflected by the reflective plane 6 and concentrated to the direction of the horn mouth 4.
[0026] Working principle: When the linear motor 2 in the gamepad starts, the vibration sound generated first enters the resonance cavity 3. In the resonance cavity 3, the sound is reflected to the direction of the horn mouth 4 after encountering the reflective plane 6. Due to the synergistic effect of multiple reflective planes 6, the sound is continuously reflected and converged in the resonance cavity 3, and finally transmitted to the outside of the gamepad through the horn mouth 4 and the sound hole 5. During the game, players can clearly hear stronger vibration sounds, such as more obvious vibration sounds of gun shooting in shooting games, which enhances the realism and immersion of the game.
[0027] Embodiment two: as shown in Figure 4 , Figure 5 and Figure 6 , an amplification structure of a gamepad sound-emitting motor, including an eccentric motor 7 (vibration motor) installed inside the gamepad shell 1. The eccentric motor 7 is installed on one side near the holding position inside the handle, so that players can more intuitively feel the vibration. The eccentric motor 7 is externally provided with a resonance cavity 3 for collecting and amplifying the sound generated by the eccentric motor 7. The resonance cavity 3 is provided with a horn mouth 4 facing outward to the gamepad shell 1, and the resonance cavity 3 is integrally formed with the gamepad shell 1 by using high-toughness plastic through injection molding process. This way not only simplifies the production process, but also reduces the connection gaps between parts and the possibility of sound leakage. By using the high-precision characteristics of the injection molding process, the shape and size of the resonance cavity 3 meet the acoustic design requirements, which can effectively collect and amplify the vibration sound. The horn mouth 4 and the resonance cavity 3 are synchronously formed during the injection molding process, ensuring a tight connection and smooth sound transmission.
[0028] The gamepad shell 1 is provided with a circular sound hole 5 with a diameter of 2mm at a position corresponding to the horn mouth 4, and the sound holes 5 are uniformly distributed in a circular array. The spacing between the sound holes 5 is calculated to ensure the uniformity and clarity of sound transmission.
[0029] This embodiment uses a reflective curved surface 8 as a reflective structure. The reflective curved surface 8 is integrally formed with the gamepad shell 1, the resonance cavity 3, and the horn mouth 4. The reflective curved surface 8 is in the shape of a parabola, with the eccentric motor 7 as the center and uniformly distributed inside the resonance cavity 3. The parabolic reflective curved surface 8 can focus and reflect the sound emitted by the eccentric motor 7 to the direction of the horn mouth 4, realizing the concentrated transmission of sound.
[0030] Working principle: when the eccentric motor 7 works, the vibration sound is transmitted into the resonance cavity 3. In the resonance cavity 3, the sound is focused and reflected by the reflecting curved surface 8, and is propagated to the loudspeaker mouth 4 along a specific direction. Due to the focusing effect of the reflecting curved surface 8, the sound energy is more concentrated during propagation, and when the sound is propagated to the outside of the game handle through the loudspeaker mouth 4 and the sound hole 5, the sound is louder. For example, when playing a racing game, the vibration sound of vehicle acceleration and collision can be more clearly conveyed to the player, improving the game experience.
[0031] The sound amplification structure of the game handle sound generating motor of the utility model is actually applied to a game handle, as shown in Figure 7
[0032] The above is only the preferred embodiment of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
