[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0020] The following detailed description uses specific examples.

[0021] Please refer to Figure 1 and Figure 2 According to one embodiment of the present invention, a micro-speaker system is provided. The system mainly consists of two parts: a support body 01 and a housing 02. A moving-coil speaker 03 and an electromagnetic excitation driver 04 are installed in the housing 02 to produce sound.

[0022] The structure of the box is as follows Figure 2 As shown, the device includes a cylindrical cylinder 021, a conical cylinder 022 located inside the cylindrical cylinder 021, and a base plate 023 enclosed at the bottom of the cylindrical cylinder 021. The conical cylinder 022 has a larger upper end that is sealed to the top of the cylindrical cylinder 021 and a smaller lower end that extends into the cylindrical cylinder 021. The cylindrical cylinder 021, the conical cylinder 022, and the base plate 023 together form a cavity 020, which is used to house a moving-coil loudspeaker 03 and an electromagnetic excitation driver 04. Preferably, the cylindrical cylinder 021 and the conical cylinder 022 are made of a thin-walled material, such as metal or plastic.

[0023] The support 01 is supported on the outside of the box 02, making the box 02 form an angle with the horizontal plane. This angle refers to the angle θ between the central axis of the box 02 and the horizontal plane. Specifically, the central axis refers to the central axis of the cylinder 021 or the central axis of the cone 022, and the cylinder 021 and the cone 022 are coaxial. The angle can be selected between 40 degrees and 60 degrees, preferably around 50 degrees.

[0024] The support body 01 is generally L-shaped and has two support arms. The two ends of the support body 01 (i.e., the ends of the two support arms) are respectively connected to the upper and lower ends of the cylinder 021. The bottom of the support body 01 has a horizontal support surface (i.e., the bottom surface of one of the support arms), which is used to place the support body on a horizontal surface and support the entire system.

[0025] The system of this invention is formed by combining a housing 02 and a support 01, mimicking the unique shape of a tilted cup, roughly resembling an inverted cup. A cavity is formed between the support 01 and the cylinder 021, allowing one or more fingers to pass through, so that the support 01 can serve as a handle for the housing 02 (i.e., a handle for the cup).

[0026] Since the cup opening (i.e., the opening at the top of the cylindrical housing) of the micro-speaker system of the present invention is open during use, it is best to place the cup upside down on a table when not in use to prevent foreign objects and dust from entering. Alternatively, in some embodiments, a protective device may be added, such as covering the top of the cylinder 021 with a dustproof net.

[0027] Furthermore, to remind users and add a touch of humor, the present invention can use humorous patterns on the surface of the housing 02, preferably two images that are quite different when the housing is upright and when it is upside down. For example: when upright... Figure 3 , Figure 5 The pattern, when inverted and reversed, is like... Figure 4 , Figure 6 The pattern. Figure 4 , Figure 6 They are Figure 3 , Figure 5 The inverted diagrams are shown here. They are not all listed here.

[0028] In this embodiment of the invention, the moving-coil loudspeaker 03 is disposed at the lower end of the conical cylinder 022, with its sound-emitting surface facing the upper end of the conical cylinder 022. The cavity 020 inside the housing 02 serves as the sound chamber of the moving-coil loudspeaker. The electromagnetic excitation driver 024 is disposed within the cavity 020 and attached to the base plate 023. The moving-coil loudspeaker 03 can be a conventional moving-coil electrodynamic loudspeaker, and this is not a limitation 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. The iron shaft core is bonded and fixed to the base plate 023.

[0029] When an audio signal is applied to the system, the moving-coil speaker vibrates and produces sound. Simultaneously, current flows through the coil of the electromagnetic excitation driver, causing the iron shaft core to move axially and thus exciting the base plate 023 to vibrate. Since the base plate 023 is connected to the cylinder 021 and the conical cylinder 022, which are made of thin-walled material, the entire housing 02 vibrates together, thereby driving the housing 02 to vibrate and produce sound.

[0030] In this embodiment of the invention, the leads of the moving-coil speaker 03 and the electromagnetic excitation driver 04 can be led out from the cavity 020 at the connection between the support body 01 and the housing 02, pass through the hollow space inside the support body 01, and connect to the control circuitry located inside the support body 01. The surface of the support body 01 may be provided with several control buttons and indicator lights connected to the control circuitry, such as power buttons, play buttons, volume buttons, etc.

[0031] The present invention can be made to allow signals to be directly input from the outside via signal lines. That is, a USB interface (or other type of interface) connected to the control circuit is provided on the surface of the support body 01 to receive signals from external devices such as USB flash drives, memory cards, and mobile phones.

[0032] The present invention can also be made into an intelligent form, using a wireless method to receive signals from the outside. That is, at least one of the wireless modules such as Bluetooth module, WiFi module, and cellular communication module is set inside the support body 01 and connected to the control circuit part, so as to connect with and receive signals from external devices wirelessly.

[0033] In summary, this invention discloses a micro-speaker system. On one hand, the system utilizes a conventional electromagnetic loudspeaker to produce sound. On the other hand, the system also utilizes an electromagnetic excitation driver to excite the enclosure to vibrate and produce sound. This vibration-based sound generation method is similar to the vibration principle of a common planar loudspeaker, but it differs significantly from the radiating vibration sound generation of a traditional loudspeaker. This is because it uses an electromagnetically excited driver attached to a planar material such as a base plate. When conductive, this driver causes the base plate and enclosure to vibrate in a wave-like manner. Ultimately, the two sound generation methods are combined to transmit the sound.

[0034] The beneficial effects of this invention include: This invention combines a commonly used moving-coil loudspeaker with a method that uses an electromagnetic excitation driver to excite the housing to vibrate. These two sound-generating methods complement each other, compensating for their respective shortcomings in certain frequency bands. Overall, it exhibits better performance in the low, mid, and high frequency ranges, thus improving the product's acoustic performance. Furthermore, the overall shape formed by the combination of the enclosure and support body is modeled after a tilted cup, simple yet unique. Additionally, humorous patterns can be designed on the enclosure to enhance its appeal.

In the above embodiments, the descriptions of each embodiment have their own emphasis, and for parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; however, these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and protection scope of the technical solutions of the embodiments of the present invention.
