Detailed Description

In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The following will explain details by way of specific examples.

Referring to fig. 1 and 2, an embodiment of the present invention provides a micro-sound system, which mainly comprises a support body 01 and a box body 02, wherein a moving-coil speaker 03 and an electromagnetic excitation driver 04 are installed in the box body 02 to generate sound.

The structure of the box is shown in fig. 2, and comprises a cylinder 021, a cone 022 located inside the cylinder 021 and a bottom plate 023 enclosed at the bottom of the cylinder 021, wherein the cone 022 has a larger upper end hermetically connected with the top of the cylinder 021 and a smaller lower end extending into the cylinder 021, the cone 022 and the bottom plate 023 enclose a cavity 020, and the cavity 020 is used for accommodating the moving-coil speaker 03 and the electromagnetic excitation driver 04. The cylinder 021 and the cone 022 are preferably punched from a thin-walled material, and a metal material or a plastic material may be used as the thin-walled material.

The support body 01 is supported outside the box body 02, so that an included angle is formed between the box body 02 and the horizontal plane. The included angle is an included angle theta between a central axis of the box body 02 and a horizontal plane, specifically, the central axis refers to a central axis of the cylinder 021 or a central axis of the cone 022, and the cylinder 021 and the cone 022 are coaxial. The included angle can be selected from 40 degrees to 60 degrees, and preferably, the included angle is about 50 degrees.

The support body 01 is substantially L-shaped with two support arms. Both ends of the support body 01 (i.e., the ends of the two supporting arms) are connected to the upper and lower ends of the cylinder 021, respectively. The bottom of the support body 01 has a horizontal support bottom surface (i.e., the bottom surface of one of the support arms) for being placed on a horizontal surface to support the entire system.

The overall shape of the system of the invention formed by the combination of the box body 02 and the support body 01 imitates the unique shape of a cup placed obliquely, and is approximately similar to an obliquely inverted cup. Wherein, a hollow space for allowing one or more fingers to pass through is formed between the support body 01 and the cylinder 021, so that the support body 01 can be used as a handle of the box body 02 (namely, a handle of a cup).

Because of the micro-sound system of the present invention, the cup rim (i.e., the opening at the top of the tank cylinder) is open during use, and preferably should be inverted on a table top when not in use in order to prevent foreign objects and dust from entering. Alternatively, in some embodiments, a protective device can be added, such as a dust screen covering the top of the cylinder 021.

Further, in order to remind the user and increase humorous interest, the invention can use some humorous interesting patterns on the surface of the box body 02, and preferably adopts two images with greatly different images in forward placement and reverse placement. For example: the patterns shown in fig. 3 and 5 are shown in the forward direction, and the patterns shown in fig. 4 and 6 are shown in the reverse direction. Fig. 4 and 6 are inverted views of fig. 3 and 5, respectively. Not all of which are shown here by way of example.

In the embodiment of the present invention, the moving-coil speaker 03 is disposed at the lower end of the cone 022, the sound emitting surface faces the upper end of the cone 022, and a cavity 020 inside the box 02 serves as a sound cavity of the moving-coil speaker; the electromagnetically actuated driver 024 is disposed within the cavity 020 and attached to the bottom plate 023. The moving-coil loudspeaker 03 can be a conventional moving-coil electrodynamic loudspeaker, and is not limited herein. The electromagnetic excitation driver 04 may structurally include a ring magnet, a coil located inside the ring magnet, and an iron shaft core driven by the coil, and the iron shaft core is bonded and fixed to the bottom plate 023.

The moving coil speaker vibrates to sound when an audio signal is applied to the system. Meanwhile, the coil of the electromagnetic excitation driver is electrified, so that the iron shaft core body moves along the axial direction to enable the bottom plate 023 to vibrate in an excitation mode, and the bottom plate 023 is connected with the cylinder 021 and the conical cylinder 022 which are punched by thin-wall materials, so that the whole box body 02 can vibrate together, and the box body 02 is driven to vibrate and sound.

In the embodiment of the present invention, the leads of the moving-coil speaker 03 and the electromagnetic excitation driver 04 may be led out from the cavity 020 at the connection between the supporting body 01 and the casing 02, penetrate into the hollow space inside the supporting body 01, and be connected to the control circuit portion provided inside the supporting body 01. The surface of the support body 01 can be provided with a plurality of control keys and indicator lights connected with a control circuit, such as an on-off key, a play key, a volume key and the like.

The invention can be made into a structure that the signal is directly input from the outside through a signal line, namely, a USB interface (or other interface) connected with the control circuit part is arranged on the surface of the supporting body 01 and is used for receiving the signal of the equipment such as an external U disk, a memory card, a mobile phone and the like.

The present invention may also be made in an intelligent type, and signals are input from the outside in a wireless manner, that is, at least one of wireless modules such as a bluetooth module, a WiFi module, a cellular communication module, etc. connected to the control circuit portion is provided inside the support body 01, and signals are connected and received with an external device in a wireless manner.

In summary, the embodiment of the invention discloses a micro-sound system. In one aspect, the system utilizes a conventional electromagnetic speaker to produce sound. On the other hand, the system also utilizes an electromagnetic excitation driver to excite the box body to generate vibration sound, the vibration sound generation mode is the same as the sound generation vibration principle of a common plane loudspeaker, but the radiation vibration sound generation mode is very different from the radiation vibration sound generation mode of a traditional loudspeaker, because the electromagnetic excitation driver is adhered to a plane plate material such as a bottom plate, and when the electromagnetic excitation driver is conductive, the electromagnetic excitation driver drives the bottom plate and the box body to generate wave type vibration. Finally, the two sound producing modes are combined to conduct the sound out.

The technical scheme of the invention has the beneficial effects that: the invention combines the common moving-coil loudspeaker with the shell excited by the electromagnetic excitation driver to generate vibration, and the two sound production modes are complementary, thereby overcoming the defect that the two sound production modes are not good enough in certain frequency bands, having better performance in low, medium and high frequency bands on the whole and improving the acoustic performance of the product. Furthermore, the integral shape formed by combining the box body and the supporting body is simple and unique by imitating the shape of obliquely placing the cup. In addition, humorous patterns can be designed on the box body, so that the interest is improved.
