Description

Technical Field

[0001] This utility model relates to the field of speaker technology, and more specifically, to a multi-functional vehicle speaker with lifting function. Background Technology

[0002] A speaker enclosure mainly consists of a horn and a cabinet. Car speakers are a type of speaker that can be used in automobiles to enhance entertainment while driving. Some existing car speakers have a fixed horn position, typically located inside the cabinet. This makes the sound waves emitted by the horn easily blocked or interfered with by the cabinet or other external trim, resulting in a less clear and transparent sound to the human ear.

[0003] Some existing speakers with lifting functions only have a lifting function for their speakers. When raised, the sound waves emitted are less likely to be blocked or interfered with. However, the speakers are not detachable from the enclosure, making it inconvenient to remove the speakers for separate use. The function is relatively simple and the usage scenarios are limited. In addition, some existing car speakers can only be raised and lowered vertically, and it is not convenient to adjust the angle in the horizontal direction. That is, it is not convenient to adjust the sound output direction of the speakers according to the needs. The function is limited and the performance is not good. Utility Model Content

Detailed Implementation

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.

[0030] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0031] See Figures 1-12 This utility model provides a vehicle-mounted multi-functional speaker with lifting function, including a cabinet base 1 and a speaker body 2. The cabinet base 1 is provided with a lifting mechanism for driving the speaker body 2 to rise and fall. The lifting mechanism includes a lifting seat 3 and a driving component for driving the lifting seat 3 to rise and fall. The speaker body 2 is detachably connected to the lifting seat 3. The cabinet base 1 is provided with a first power supply unit 101, and the speaker body 2 is provided with a speaker 201 and a second power supply unit 202 electrically connected to the speaker 201. When the speaker body 2 is connected to the lifting seat 3, the driving component drives the lifting seat 3 and the speaker body 2 to rise and fall synchronously. The first power supply unit 101... 1 is electrically connected to speaker 201 and is powered by the first power supply unit 101; when speaker body 2 is detached from the lifting seat 3, speaker 201 is powered by the second power supply unit 202; this utility model has a vehicle-mounted multi-functional speaker with lifting function, the speaker body can be raised and lowered, and when raised, it is convenient to transmit sound waves to the human ear and improve the listening experience; when the speaker body is retracted, it can reduce the space occupied by the external space and optimize space utilization; when the speaker body is connected to the cabinet seat, it can be rotated to adjust the sound output angle to meet different user needs; at the same time, the speaker body can be detached and used independently, with multiple functions and multiple usage scenarios.

[0032] Specifically, the speaker body 2 is placed on the upper side of the lifting seat 3. When the lifting seat 3 is raised and lowered vertically, the speaker body 2 is also raised and lowered synchronously. After being raised, the sound waves emitted by the speaker body 2 are less likely to be blocked or interfered with by the enclosure seat 1 or other components, so that the sound waves can be transmitted to the human ear, making the sound clearer and brighter. In addition, the lifting action itself has a dynamic visual effect, which can enhance the luxurious atmosphere in the car and enhance the user experience. This utility model of a car multi-functional speaker with lifting function can be placed on the car's center console and used as a car center speaker. This car multi-functional speaker can be connected to the car's infotainment system via Bluetooth, transmission line, etc. The speaker can be connected to the car's infotainment system, and corresponding programs can be set to control its lifting function, volume, audio parameters, etc. Since the speaker body 2 is detachable, users can directly remove the speaker body 2 when parking and leaving the car, and use it to play audio through the second power supply unit 202 on the speaker body 2. For example, in some camping scenarios, when users drive to the campsite, they can connect the speaker body 2 to the cabinet base 1 to use it as a car center speaker; when they arrive at their destination and leave the car, they can directly remove the speaker body 2 to use it as a portable speaker. It has multiple ways of use and a good user experience.

[0033] See Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7 The lifting seat 3 is slidably mounted on the housing seat 1 in a vertical direction. The lifting mechanism includes a rotating frame 41 and a motor 42 for driving the rotating frame 41 to rotate. The rotating frame 41 is provided with a lifting ramp 411, and the lifting seat 3 is provided with a protrusion 301. The protrusion 301 abuts against the upper side of the lifting ramp 411. The output shaft of the motor 42 is connected to the rotating frame 41. When the rotating frame 41 rotates, it lifts the protrusion 301 through the lifting ramp 411, thereby lifting the lifting seat 3 and the horn body 2 upward. After being lifted to the preset highest position, the motor 42 stops and keeps the rotating frame 41 in that position. When it is necessary to retract the lifting seat 3 and the horn body 2, the motor 42 reverses to drive the rotating frame 41 to rotate back to the initial position, so that the lifting seat 3 and the horn body 2 descend and retract. After retracting into place, the motor 42 stops.

[0034] See Figure 1 , Figure 5 , Figure 6 and Figure 7 Two lifting ramps 411 are rotationally symmetrically arranged, and two protrusions 301 are symmetrically arranged. Each protrusion 301 corresponds one-to-one with a lifting ramp 411, ensuring smooth lifting and preventing tilting or jamming of the lifting seat 3 during lifting. A curved surface 3011 is provided on the side of the protrusion 301 closest to the corresponding lifting ramp 411, allowing the curved surface 3011 to fit more closely to the lifting ramp 411, resulting in smoother sliding of the protrusion 301 along the lifting ramp 411. A slider 302 is provided on the lifting seat 3, and a sliding contact is provided on the housing seat 1 to slide along the slider 302. The sliding groove 102 is dynamically fitted and extends vertically. The slider 302 slides vertically within the sliding groove 102, making the lifting seat 3 rise and fall smoothly. There are two sliders 302 symmetrically arranged, and there are also two corresponding sliding grooves 102. A reset spring 5 is connected between the lifting seat 3 and the housing seat 1. The reset spring 5 is used to drive the lifting seat 3 to descend and reset. When it is necessary to retract the lifting seat 3 and the horn body 2, the motor 42 reverses to drive the rotating frame 41 to rotate to the initial position. At this time, the elastic force of the reset spring 5 assists the lifting seat 3 to slide down and reset smoothly.

[0035] See Figure 1 , Figure 3 and Figure 6The first power supply unit 101 includes a first battery 1011, a first control board 1012, and a first electrical connector 1013. Both the first battery 1011 and the first electrical connector 1013 are electrically connected to the first control board 1012. The first electrical connector 1013 is mounted on the lifting base 3. The speaker body 2 is provided with a second electrical connector 203 corresponding to the first electrical connector 1013, and the second electrical connector 203 is electrically connected to the speaker 201. When the speaker body 2 is connected to the lifting base 3, the first electrical connector 1013 and the first electrical connector 201 are electrically connected. The two electrical connectors 203 are electrically connected; the first power supply unit 101 is built into the cabinet base 1, and the cabinet base 1 is provided with a charging port 103 for charging the first battery 1011; since the first battery 1011 is provided on the cabinet base 1, when the speaker body 2 is connected to the lifting base 3, the speaker 201 can be powered by the first battery 1011 on the cabinet base 1, and the second power supply unit 202 can also be charged and replenished by the first battery 1011 on the cabinet base 1, thus functioning as a charging base, which is convenient to use.

[0036] See Figure 3 , Figure 4 , Figure 9 , Figure 11 and Figure 12 The second power supply unit 202 includes a second battery 2021 and a second control board 2022. The speaker 201, the second battery 2021, and the second electrical connector 203 are all electrically connected to the second control board 2022. The first electrical connector 1013 is a female electrical connector with a insertion groove 1014, and the second electrical connector 203 is a male electrical connector with a insertion post 2031. The first electrical connector 1013 and the second electrical connector 203 conduct electricity upon insertion, so that when the speaker body 2 is placed on the cabinet base 1, the two are electrically connected without the need for additional electrical connection steps, making operation convenient. The second power supply unit 202 is built into the speaker body 2. When the speaker body 2 is connected to the cabinet base 1, the second power supply unit 202 is built into the speaker body 2. When the speaker body 2 is connected to the lifting seat 3, the second battery 2021 can be charged and replenished through the first battery 1011 on the housing seat 1, thus functioning as a charging seat. The speaker body 2 is rotatably connected to the housing seat 1. When the speaker body 2 rotates relative to the housing seat 1 by external force, the speaker body 2 has a rotation axis perpendicular to the horizontal plane. The first electrical connector 1013 and the second electrical connector 203 are always electrically connected. This allows the speaker body 2 to adjust its sound output angle according to needs, making adjustment convenient. For example, it can be adjusted to output sound towards the driver or passenger side to improve the auditory experience of people in a specific direction, or it can be adjusted to the middle direction between the driver and passenger to balance the auditory experience of the driver and passenger.

[0037] See Figure 5 , Figure 10 and Figure 12The speaker enclosure 1 is equipped with a power switch 7, which controls the power-on and power-off functions of the speaker. The speaker body 2 is equipped with a ring-shaped light strip 8, which in this embodiment is a multi-color light strip, serving as an ambient light. Upgraded functions, combined with the light strip, enhance visual dynamics and thus improve the in-car atmosphere. Furthermore, the light strip 8 can also alleviate fatigue. The specific principle is as follows: the ambient light can use soft, gradual light or rhythmically changing light effects, such as moving with music. This dynamic change can stimulate the optic nerve of the eye, relieving fatigue caused by prolonged staring. It supports multi-color adjustment and can emit low-saturation warm tones such as pale yellow and light blue. This type of light is closer to natural light, reducing pupil constriction pressure and thus soothing eye muscles. The power switch 7 is electrically connected to the first control board 1012, and the light strip 8 is electrically connected to the second control board 2022. The second control board 2022 is equipped with a Bluetooth module for connecting to external mobile devices to play audio, making it convenient to use. In this embodiment, the electrical connections can be made using wires or other methods.

[0038] See Figure 3 , Figure 4 , Figure 9 and Figure 11 A magnetic attraction mechanism is provided between the enclosure base 1 and the speaker body 2. The magnetic attraction mechanism includes a first magnet 61 disposed on the enclosure base 1 and a second magnet 62 disposed on the speaker body 2. The first magnet 61 and the second magnet 62 attract each other and are both ring-shaped. A first electrical connector 1013 is placed inside the first magnet 61 and a second electrical connector 203 is placed inside the second magnet 62, so that the speaker body 2 can be quickly assembled and disassembled from the enclosure base 1, and the installation position is accurate and the connection is reliable.

[0039] See Figure 1 , Figure 3 , Figure 5 and Figure 10 The speaker body 2 is spherical, and the housing base 1 is provided with an arc-shaped placement groove 104 for placing the speaker body 2. Specifically, the arc-shaped placement groove 104 is provided on the upper side of the lifting base 3, so that the speaker body 2 is placed stably. The speaker body 2 can be disassembled and used separately, which is convenient for holding and using, and the spherical speaker body 2 also has a certain playability. The outer shell of the speaker body 2 is spherical, and the outer shell has a sound outlet hole 204 corresponding to the speaker 201. The speaker 201 is tilted upward and has a tilted upward sound outlet surface 2011. The sound outlet surface 2011 forms an angle A with the horizontal plane. The angle A is 100°-140°. In this embodiment, the angle A is 115°, which is moderate and can output sound well at the height of the human ear. Since the height of the car center console is lower than the height of the human ear, the tilted setting of the sound outlet surface 2011 makes it easier to point the speaker 201 towards the human ear to output sound, thereby improving the listening experience.

[0040] This utility model features a multi-functional car speaker with a lifting function. The speaker body can be raised and lowered, facilitating the transmission of sound waves to the ear and improving the listening experience. When retracted, the speaker body reduces its external space occupation, optimizing space utilization. When connected to the cabinet base, the speaker body can rotate to adjust the sound output angle, meeting different user needs. The speaker body can also be detached for independent use, offering diverse functions and applications. Two symmetrically arranged lifting ramps and two symmetrically arranged protrusions are provided, each corresponding to a lifting ramp, ensuring a smooth lifting process and preventing tilting or jamming during the lifting process. The side of the protrusion closest to the corresponding lifting ramp has an arc-shaped surface, allowing for a closer fit and smoother sliding along the ramp. The speaker is tilted upwards with an upward-facing sound output surface, which directs the speaker towards the ear for improved listening experience.
