detailed description

The content of the present invention will be described in detail below with reference to the accompanying drawings:

As shown in FIGS. 1 and 2, a speaker device 10 according to an embodiment of the present invention includes an auxiliary system, a vibration system, and a magnetic circuit system. The auxiliary system front cover 11 and the outer casing 12, the front cover 11 and the outer casing 12 form a space for housing and fixing the vibration system and the magnetic circuit system, and the vibration system and the magnetic circuit system are housed and fixed in the space. The vibration system includes a diaphragm 2, a reinforcing portion 4 disposed on the diaphragm 2, and a voice coil 3 fixed to the diaphragm, the diaphragm 2 being fixed between the front cover 1 and the outer casing 12; the magnetic circuit system including the magnetic yoke 6. The magnet 51 fixed to the side of the front cover 11 of the yoke 6 and the washer 52 fixed to the side of the magnet 51 away from the yoke 6 are fixed to the outer casing 12. A magnetic gap is disposed between the yoke 6 and the magnet 51, and the voice coil 3 is suspended in the magnetic gap. When the external current enters the voice coil 3, the voice coil 3 disposed in the magnetic gap subfield is vibrated up and down by the ampere force, and the voice coil 3 vibrates to vibrate the diaphragm 2, and the diaphragm 2 drives the air to sound.

In the speaker device of the present invention, the front cover 11 and the outer casing 12 are both flexible structures. The front cover 11 and the outer casing 12 may be bent at an angle by external stress, and the diaphragm 2 includes There is a folding ring portion, which is a bendable structure. When the front cover 11 and the outer casing 12 are bent by an external force, the diaphragm 2 is also bent correspondingly, and the diaphragm fold ring is a bendable structure, which can ensure the normal operation of the diaphragm 2 when the diaphragm 2 is deformed, that is, the speaker. The normal sound of the device. The speaker device of the present invention can bend to a certain extent without affecting the normal operation of the speaker device, expand the application field of the speaker device, and facilitate the application of the speaker device.

As a refinement, any or all of the front cover 11 and the outer casing 12 are injection molded soft silicone materials, and the flexibility of the front cover 11 and the outer casing 12 can be ensured. Of course, other flexible materials can be used for the front cover and the outer casing in practical applications.

As shown in FIG. 2 and FIG. 3, the diaphragm 2 2 can be provided with a plurality of spaced apart convex portions and recessed portions. In a more detailed manner, the folded portion 2a is provided in a wavy or polygonal shape, and has a wave shape. Or the fold-shaped loop portion 2a can ensure that when the outer side of the diaphragm is bent with the front cover and the fixed portion of the outer casing, the folding portion 2a is deformed similarly to the spring, and the bending stress is cancelled, thereby preventing the bending from vibrating the diaphragm. The effect is to ensure the normal vibration of the diaphragm.

As shown in FIG. 2, as a preferred embodiment, the diaphragm 2 is fixed between the front cover 11 and the outer casing 12, and the front cover 11 and the outer casing 12 are provided with a relief structure corresponding to the folded portion of the diaphragm 2.

The acoustic performance of the lower speaker unit.

As shown in FIG. 2, the yoke 6 protrudes from the outer casing 12, and the side of the yoke 6 that exposes the outer casing 12 is curved. The arcuate design of the yoke 6 determines the arcuate direction corresponding to the direction of the bend of the outer casing 12, improving the comfort of the bendable speaker of the present invention. The curved design of the yoke 6 can ensure that the entire speaker device is curved when the outer casing 12 and the front cover 11 are bent, which is advantageous for improving the bendability of the speaker device.

Figure 4 shows a specific application of the smart wristband device to which the above bendable speaker is applied. 4 is a smart watch 7, as shown in FIG. 4, the smart watch includes a wristband 7a, and the speaker 10 is disposed in the wristband 7a, which does not occupy the space of the dial of the smart watch 7, and is advantageous for the thin design of the dial. The bendable speaker 10 can correspond to the shape of the wristband 7a, the wristband 7a does not need to be thickened for the position of the speaker 10, which is advantageous for the thin design of the wristband 7a. At the same time, the bendable speaker 10 can be bent according to the specific curvature of the wearer's wrist, thereby improving the comfort of wearing the smart watch. As shown in FIG. 4, in order to improve the sounding effect of the smart watch, two speakers 10 are disposed in the wristband 7a, and the two speakers 10 are symmetrically designed with respect to the dial. The two speakers 10 constitute a sounding array, which effectively improves the sounding effect of the smart watch. In summary, the smart wrist wearing device with the bendable speaker 10 is thin and designed, beautiful and comfortable to wear. It should be understood that the smart watch listed in this embodiment is only a specific manner of the smart wristband device, and is not used to limit the smart wristband device of the present invention. In practical applications, other devices such as a smart wristband can also be bent by the present invention. The folding speaker is subject to the protection scope of the present invention.

The above is only the embodiment of the present invention, and is not intended to limit the present invention, and equivalent modifications or variations made by those skilled in the art in light of the present invention are included in the scope of the claims.
