Technical Field
[0001] The invention relates to a loudspeaker. Background Art
[0002] A speaker is a very common sound player. The function of a speaker is to convert electrical signals into mechanical vibrations of a diaphragm, thereby causing changes in the density of the surrounding air to produce sound for people around to hear.
[0003] For some large speakers, in order to enhance the sound pressure in the low-frequency band, a bass enhancement device is generally added to the speaker, such as a bass reflex tube (Bass reflex) or a passive radiator (Passive Radiator), etc., to utilize the characteristics of phase inversion to achieve the effect of enhancing the low frequency.
[0004] With the development of thinner speakers, many speakers (such as smartphones, tablets or laptops, etc.) have small internal space, so most of them use miniature speakers to reduce the volume and thickness. However, the volume of the miniature speaker is very small, which will reduce the original output performance of the speaker.
[0005] Therefore, many private enterprises or related academic research institutions have invested a lot of money, manpower and time in researching speakers and are eager to improve the various characteristics of speakers. Summary of the invention

[0045] The following will disclose multiple embodiments of the present invention with drawings. For the purpose of clear description, many practical details will be described together in the following description. However, it should be understood that these practical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these practical details are not necessary. In addition, in order to simplify the drawings, some conventional structures and components will be depicted in a simple schematic manner in the drawings.
[0046] Please refer to Figure 1 , Figure 1 1 is a three-dimensional schematic diagram of a speaker 100 in some embodiments of the present invention, wherein the speaker 100 is an electronic device with a sound playback function, so the speaker 100 can be, for example, a laptop, a tablet computer, a mobile device (such as a smart phone), but the present invention is not limited thereto. The housing 110 of the speaker 100 forms a receiving space, and a rubber sound box 130 and a sound output unit 150 are disposed inside the housing 110 to facilitate playback of various forms of sound.
[0047] Please refer to Figures 2 to 6 , Figure 2 The internal structure of the speaker 100 is shown. Figure 3 The bottom view of the rubber sound box 130 , the sound unit 150 and the plastic fixing ring 170 is shown. Figure 4 Based on Figure 2 A cross-sectional view taken along section line A in FIG. Figure 5 A three-dimensional schematic diagram of the plastic fixing ring 170 is shown. Figure 6 The plastic fixing ring 170 is different from Figure 5A stereoscopic schematic diagram from a viewing angle. In one or more embodiments of the present invention, the rubber speaker 130 is fixed to the housing 110, and the rubber speaker 130 accommodates the sound unit 150. In addition, the plastic fixing ring 170 is connected between the rubber speaker 130 and the sound unit 150, and the plastic fixing ring 170 surrounds the sound unit 150, and the rubber speaker 130 surrounds the plastic fixing ring 170. Specifically, the plastic fixing ring 170 includes a plurality of extension arms 171, and the plurality of extension arms 171 are arranged around the outer periphery of the plastic fixing ring 170. In addition, the extension arm 171 is roughly T-shaped or mushroom-shaped, so as to facilitate fixing the plastic fixing ring 170 to the rubber speaker 130, but the present invention is not limited thereto. In other words, the extension arm 171 has a first width W1 and a second width W2, wherein the first width W1 is greater than the second width W2, wherein the first width W1 is farther from the center of the plastic fixing ring 170, and the second width W2 is closer to the center of the plastic fixing ring 170, so as to facilitate fixing the plastic fixing ring 170 to the rubber sound box 130. Since the rubber sound box 130 is made of a soft material, a larger assembly gap can be reserved, and the rubber sound box 130 can occupy a larger sound box volume under the same accommodation space. In addition, the characteristics of the rubber sound box 130 as a soft material can absorb the sound waves generated by the sound unit 150, and prevent the sound waves from resonating with other components of the speaker 100 to generate noise.
[0048] During the actual assembly, since the rubber speaker 130 is difficult to be bonded with ordinary adhesive, the sound unit 150 and the plastic fixing ring 170 can be fixed to each other by using dispensing glue or ultraviolet resin, and then the rubber is directly formed on the plastic fixing ring 170 by using an injection molding process to form the rubber speaker 130. Then, the rubber speaker 130 is fixed in the shell 110 to obtain the speaker 100 of the present invention, but the present invention is not limited thereto.
[0049] In one or more embodiments of the present invention, the rubber speaker 130 has a turning bottom 131, wherein a first portion 131a of the turning bottom 131 is connected to the housing 110 and extends toward the outside of the rubber speaker 130. In addition, the speaker 100 further includes a double-sided adhesive S, which is used to fix the turning bottom 131 and the housing 110. In practical applications, the double-sided adhesive S can more firmly fix the rubber speaker 130 to other objects (such as the housing 110) than general glue. Therefore, the double-sided adhesive S can be directly connected between the housing 110 and the rubber speaker 130. Specifically, the double-sided adhesive S can be, for example, a double-sided acrylic adhesive or a double-sided silicone adhesive, but the present invention is not limited thereto.
[0050] In one or more embodiments of the present invention, the material of the plastic fixing ring 170 can be thermoplastic plastic or thermosetting plastic, wherein the plastic fixing ring 170 is manufactured by an injection molding process, but the present invention is not limited thereto. In one or more embodiments of the present invention, the plastic fixing ring 170 can include a circular ring structure, a triangular ring structure, a square ring structure or any polygonal ring structure, so the "ring" mentioned in the present invention is used to represent a locking or non-locking structure extending around, and is not used to limit any shape. It is not used to limit any shape. The rubber speaker 130 has an annular protrusion 133, and the plastic fixing ring 170 includes an annular groove 173, wherein the annular groove 173 is connected to the annular protrusion 133, whereby the rubber speaker 130 and the plastic fixing ring 170 can be firmly connected to each other. The annular protrusion 133 may be in the shape of a circular ring, a triangular ring, a square ring or any polygonal ring, and the annular groove 173 may be in the shape of a circular ring, a triangular ring, a square ring or any polygonal ring, but the present invention is not limited thereto.
[0051] In one or more embodiments of the present invention, the plastic fixing ring 170 includes a stepped inner edge 175, and the stepped inner edge 175 is also annular and is used to fix the sound unit 150. Specifically, the stepped inner edge 175 can provide contact surfaces in different directions to fix the sound unit 150, and the sound unit 150 has an edge angle 151 with a shape corresponding to the stepped inner edge 175, so that the sound unit 150 can closely fit the stepped inner edge 175 through the edge angle 151, thereby improving the stability of the plastic fixing ring 170 when combined with the sound unit 150, but the present invention is not limited thereto.
[0052] In one or more embodiments of the present invention, the plastic fixing ring 170 includes an annular slope 177, wherein the annular slope 177 is disposed below the stepped inner edge 175. When the plastic fixing ring 170 fixes the sound unit 150, the annular slope 177 will gradually extend downward away from the sound unit 150, thereby facilitating demolding of the plastic fixing ring 170 after injection molding or facilitating removal of the sound unit 150 from the plastic fixing ring 170, but the present invention is not limited thereto.
[0053] Figure 7 According to some other embodiments of the present invention, Figure 2In one or more embodiments of the present invention, the rubber speaker 130 has a turning bottom 131, wherein a first portion 131a of the turning bottom 131 is connected to the housing 110 and extends toward the outside of the rubber speaker 130, and a second portion 131b of the turning bottom 131 is connected to the housing 110 and extends toward the inside of the rubber speaker 130. In short, the first portion 131a and the second portion 131b of the turning bottom 131 extend toward the inside and the outside of the rubber speaker 130, respectively, so that the first portion 131a and the second portion 131b also extend toward opposite directions, respectively, so that the turning bottom 131 has a larger contact area, so that the rubber speaker 130 is fixed to the housing 110, but the present invention is not limited thereto.
[0054] In summary, the present invention provides a loudspeaker with a rubber sound box. Since the rubber sound box is made of soft material, a larger assembly gap can be retained. Under the same accommodation space, the rubber sound box can occupy a larger sound box volume space. In addition, the characteristic of the rubber sound box as a soft material can absorb the sound waves generated by the sound unit, thereby preventing the sound waves from resonating with other components of the loudspeaker and generating noise.
