Technical Field

[0001] This utility model relates to the field of speaker technology, specifically a deformable heart-shaped speaker. Background Technology

[0002] A speaker is a sound output device, including speakers, subwoofers, etc. A speaker enclosure contains high, low, and mid-range speakers. A mini speaker is a tiny speaker, also known as a USB speaker, that connects to a computer or USB port via a USB interface. They are small, portable, and stylish. Mini speakers can connect to most audio output devices, such as MP3 players, MP4 players, mobile phones, and computers. They feature a simple and fashionable design, are compact, and come in a wide variety of styles.

[0003] To improve the bass effect, the rear acoustic chamber of existing speakers is usually large, which makes the speaker take up a lot of space and inconvenient to carry. To solve the above problems, we can refer to the portable speaker disclosed in the prior art (Chinese patent application number CN201010589743.9, application date 2010-12-15). The portable speaker has a foldable first speaker wall and a second speaker wall, and the size of the rear acoustic chamber of the portable speaker can be adjusted according to actual needs.

[0004] Although the above-mentioned device can easily adjust the size of the speaker, it still has some shortcomings in use. The shape of the speaker is not easy to adjust when using it, resulting in poor convenience when using it, as it cannot be deformed at will.

[0005] Therefore, we proposed that a deformable cardioid speaker can effectively solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a deformable heart-shaped speaker to solve the problem mentioned in the background art that the shape of the speaker is inconvenient to adjust during use, resulting in poor convenience and the inability to deform at will.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a deformable heart-shaped speaker, comprising a speaker shell, wherein the speaker shell is composed of a first shell and a second shell; a main control unit and a speaker module are provided inside the speaker shell, and one side of the main control unit is electrically connected to the speaker module; both the first shell and the second shell have inclined surfaces on their contact surfaces, and a heart-shaped deformation mechanism is provided on one side of the inclined surface, the heart-shaped deformation mechanism comprising a rotating shaft and a retaining shaft, one end of the rotating shaft being rotatably connected to one side of the second shell, and the other end being fixed to one side of the first shell, the retaining shaft being fixed at the lower end of the rotating shaft near the second shell, and the first shell and the second shell can be combined into a heart shape by rotating the rotating shaft.

[0008] As a preferred technical solution of this application, a control module is provided on the outside of the speaker housing. The output terminal of the control module is electrically connected to the connection terminal of the main control unit and is used to control the working status of the speaker module.

[0009] The control module is located on the outside of the speaker enclosure and is electrically connected to the main control unit. Users can directly control the speaker module's operating status from the outside without disassembling the speaker enclosure. This convenient and efficient operation allows for quick adjustment of volume, playback mode, and other functions, avoiding the inconvenience of internal controls.

[0010] As a preferred technical solution of this application, the lower end of the main control unit is connected to a charging module, and the outer side of the charging module is exposed on the outer side of the speaker shell, which is used to supply power to the main control unit and the speaker module.

[0011] The charging module is connected to the main control unit and exposed on the outside, eliminating the need to find a hidden interface. It can be directly powered by an external power source, providing timely power to the main control unit and speaker module, thus solving the problem of inconvenience and usability issues associated with traditional built-in charging ports.

[0012] As a preferred technical solution of this application, dust covers are attached to the outer sides of both the first and second outer shells.

[0013] The first and second outer shells are fitted with dust covers, which can effectively prevent external dust from entering the speaker cabinet, avoid dust adhering to components such as the speaker module and affecting the sound performance, reduce the frequency of component cleaning and maintenance, and extend the life of the speaker cabinet.

[0014] As a preferred technical solution of this application, a locking block is provided on the outer side of the locking shaft, and the outer side of the locking block engages with the locking groove on the inner side of the lower end of the rotating shaft, so that the rotating shaft can rotate 180 degrees; a gasket is provided on both the upper and lower sides of the inclined surface.

[0015] The locking block and the locking slot work together to limit the rotation of the pivot to 180 degrees, ensuring that the outer shell is precisely assembled into a heart shape; the inclined surface is equipped with a pad to buffer the collision when the outer shell comes into contact, to avoid wear caused by direct friction, and to ensure the stability of deformation and the integrity of the outer shell.

[0016] As a preferred technical solution of this application, both the rotating shaft and the retaining shaft have annular holes through them, and a wire harness passes through the annular holes. The two ends of the wire harness are respectively connected to the main control unit and the speaker module.

[0017] The annular holes of the hinge and retaining shaft allow the wiring harness to pass through, which can hide the connection harness between the main control unit and the speaker module. The wiring harness will not be pulled when the housing rotates, ensuring a stable connection between the two and avoiding speaker malfunction due to damage to the wiring harness.

[0018] Compared with existing technologies, the beneficial effects of this utility model are as follows: This deformable heart-shaped speaker, through the cooperation of a pivot and a locking pivot, allows the first and second outer shells to rotate precisely 180 degrees and combine into a heart shape, completely solving the pain point of traditional speakers having non-adjustable shapes; at the same time, the dust cover on the outside of the shell can reduce dust accumulation, and the pads at the sloping surfaces can buffer the shells from contact and collisions. Overall, it takes into account the flexibility of deformation, functional stability, and ease of use, comprehensively improving users' dual needs for speaker design and practicality. The specific details are as follows:

[0019] 1. The pivot connects the first and second outer shells. With the snap-fit ​​structure of the pivot and the slot, it can not only accurately control the 180-degree rotation stroke and ensure that the two outer shells are stably combined into a heart shape, but also avoid misalignment during deformation.

[0020] Furthermore, the annular holes inside the hinge and retaining shaft allow the wiring harness to pass through, preventing the wiring harness connecting the main control unit and the speaker module from being pulled and damaged when the housing rotates. This ensures the stability of the electrical component connections and provides safety support for the deformation function, effectively extending the overall lifespan of the speaker.

[0021] 2. Users can directly adjust the speaker's working status without disassembling it, making operation more efficient; the charging module is exposed on the outer shell, making it easy to quickly connect to the power supply for the main control unit and speaker module, solving the problem of inconvenience of accessing the traditional built-in charging port; at the same time, the dust cover on the outside of the shell can prevent dust from entering the interior, avoiding dust from adhering to the surface of the main control unit and speaker module and affecting performance, reducing the frequency of component maintenance, and ensuring long-term stable operation of the speaker.

[0030] Please see Figures 1-6 The present invention provides the following technical solution: a deformable heart-shaped speaker.

[0031] Example 1: To address the issue of speaker shapes being inconvenient to adjust and thus offering limited usability due to their inability to be easily deformed, please refer to the attached... Figure 1 -Appendix Figure 3 Appendix Figure 5 and attached Figure 6 The speaker enclosure 1 is composed of a first enclosure 101 and a second enclosure 102. A bevel 7 is provided on the side of the first enclosure 101 and the second enclosure 102 that are in contact with each other. A heart-shaped deformation mechanism is provided on one side of the bevel 7. The heart-shaped deformation mechanism includes a rotating shaft 9 and a retaining shaft 10. One end of the rotating shaft 9 is rotatably connected to one side of the second enclosure 102, and the other end is fixed to one side of the first enclosure 101. The retaining shaft 10 is fixed to the lower end of the rotating shaft 9 near the second enclosure 102. The rotation of the rotating shaft 9 allows the first enclosure 101 and the second enclosure 102 to be combined into a heart shape. A retaining block is provided on the outer side of the retaining shaft 10, and the outer side of the retaining block engages with a retaining groove on the inner side of the lower end of the rotating shaft 9, allowing the rotating shaft 9 to rotate 180 degrees. Gaskets 8 are provided on both the upper and lower sides of the bevel 7. An annular hole 11 is provided through the interior of both the rotating shaft 9 and the retaining shaft 10. A wire harness passes through the annular hole 11, and the two ends of the wire harness are connected to the main control unit 3 and the speaker module 4, respectively.

[0032] First, the speaker housing 1 is composed of a first housing 101 and a second housing 102. The inclined surface 7 on the side where the two housings contact each other provides a basis for fitting and deforming the two housings.

It includes a rotating shaft 9, one end of which is rotatably connected to one side of the second housing 102, and the other end fixed to one side of the first housing 101, providing support for the relative rotation of the two housings. Simultaneously, the rotating shaft 9 is near the retaining pin 10 fixed at the lower end of the second housing 102, and its outer retaining block is connected to the inner side of the lower end of the rotating shaft 9. The side slots precisely limit the rotation of the shaft 9 to only 180 degrees, ensuring that the first housing 101 and the second housing 102 can be stably combined into a heart shape after rotation. In addition, the pads 8 on the upper and lower sides of the inclined surface 7 can buffer the collision when the two housings come into contact, avoiding wear on the housings. Finally, the annular hole 11 that runs through the shaft 9 and the locking shaft 10 allows the wiring harness to pass through. The two ends of the wiring harness are connected to the main control unit 3 and the speaker module 4 respectively, ensuring that the wiring harness is not pulled when the housing is deformed, and ensuring the stability of the main control unit 3's control and sound output function of the speaker module 4.

[0033] Example 2: For easier use of this speaker, please refer to the attached document. Figure 1 and attached Figure 4 The speaker housing 1 contains a main control unit 3 and a speaker module 4.

A charging module 6 is connected to the lower end of the main control unit 3. The outside of the charging module 6 is exposed on the outside of the speaker housing 1 and is used to supply power to the main control unit 3 and the speaker module 4. Dust covers 5 are attached to the outside of both the first housing 101 and the second housing 102.

[0034] The main control unit 3 inside the speaker housing 1 is electrically connected to the speaker module 4, forming the basic sound system of the speaker. The main control unit 3 can transmit control signals to the speaker module 4 to drive the speaker module 4 to produce sound. The control module 2 on the outside of the speaker housing 1 has its output end electrically connected to the connection end of the main control unit 3. Users can send commands to the main control unit 3 through the control module 2 without disassembling the speaker, thereby controlling the volume, playback mode and other working status of the speaker module 4. The charging module 6 connected to the lower end of the main control unit 3 has its outer side exposed on the outside of the speaker housing 1. When an external power supply is connected, it can directly supply power to the main control unit 3, and then the main control unit 3 provides power to the speaker module 4, solving the problem of inconvenient charging. The dust cover 5 attached to the outside of the first housing 101 and the second housing 102 can prevent external dust from entering the inside of the speaker housing 1, avoid dust adhering to the surface of the main control unit 3 and the speaker module 4, affect performance, and extend the service life of the parts.
