Description

Technical Field

[0001] This utility model relates to the field of loudspeakers, and more specifically, to an omnidirectional microphone loudspeaker. Background Technology

[0002] A loudspeaker is a device that converts electrical signals into sound signals and plays an important role in many scenarios. However, in the existing loudspeaker technology field, there are many unsolvable problems that prevent the achievement of the excellent effect of this invention.

[0003] In terms of shield installation, traditional loudspeakers lack an effective positioning structure. Accurate alignment during installation is difficult, leading to installation deviations. This results in the shield not being stably fixed in the correct position, failing to provide adequate protection and affecting the overall protective performance of the loudspeaker.

[0004] Existing speaker designs fall short in terms of placement stability. Most back covers have flat surfaces without anti-slip textures or raised rubber pads. This results in low friction between the speaker and the surface, making it prone to sliding, shifting, or even falling under slight vibrations or impacts. Furthermore, the lack of silicone damping components allows external vibrations to be directly transmitted to the speaker's interior, interfering with normal sound production and causing sound quality distortion. Therefore, existing technologies cannot achieve the same level of accuracy and stability in the installation of the protective panel as this invention. Therefore, we propose an omnidirectional microphone speaker to address this issue. Utility Model Content

[0005] The purpose of this utility model is to address the problems raised in the existing background technology. To achieve the above-mentioned purpose, this utility model provides the following technical solution: an omnidirectional microphone loudspeaker, including a loudspeaker housing and semi-circular plates disposed at the four corners of the loudspeaker housing. A loudspeaker front panel and a loudspeaker rear cover are respectively installed on the upper and lower surfaces of the loudspeaker housing. The outer plate of the loudspeaker rear cover is provided with anti-slip texture. A raised rubber pad is fixed at each of the four corners of the loudspeaker rear cover. The raised rubber pad is made of silicone and has four pads arranged in a linear array.

[0006] As a preferred technical solution of this utility model, a speaker fixing ring plate is fixed on the bottom plate inside the speaker housing, and the speaker horn is mounted on the speaker fixing ring plate.

[0007] As a preferred technical solution of this utility model, a battery mounting bracket is connected below the speaker fixing ring plate. A power supply lithium battery is electrically connected inside the battery mounting bracket, and the power supply lithium battery is connected to the speaker horn through a circuit line. A reinforcing rib is embedded between the battery mounting bracket and the bottom of the speaker housing.

[0008] As a preferred technical solution of this utility model, a protective plate is provided inside the speaker housing, and a U-shaped groove is provided on the protective plate, with the speaker horn located in the U-shaped groove.

[0009] As a preferred technical solution of this utility model, speaker positioning rods are fixed on both sides of the protective plate, and an arc-shaped head of the positioning rod is fixed on the top of the speaker positioning rod, while the bottom is connected to the speaker housing.

[0010] As a preferred technical solution of this utility model, a speaker sound outlet hole is installed on the front panel of the speaker.

[0011] As a preferred technical solution of this utility model, a power switch is electrically connected to the upper left of the front panel of the speaker, and a volume adjustment button is electrically connected to one side of the power switch.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The speaker housing has semi-circular plates at the four corners, which can effectively buffer the impact of external collisions on the internal structure of the speaker, reduce the risk of damage caused by accidental collisions, and protect the integrity of the internal electronic components and mechanical structure.

[0015] The U-shaped groove on the protective plate surrounds the speaker, preventing external objects from directly impacting the speaker, avoiding damage, extending the speaker's lifespan, and ensuring the stability of sound playback quality.

[0016] The anti-slip texture of the back cover, combined with the raised rubber pad, increases the friction between the speaker and the surface it is placed on. At the same time, the silicone material of the raised rubber pad can play a shock-absorbing role, making the speaker more stable in various environments.

[0017] The speaker mounting ring is fixed to the bottom plate inside the speaker housing, providing a stable mounting base for the speaker and ensuring that the speaker will not shake during sound production, which helps to improve the clarity and accuracy of the sound.

[0018] The reinforcing ribs are embedded between the battery holder and the bottom of the speaker housing, enhancing the stability of the battery holder, ensuring stable power supply from the lithium battery, and avoiding problems such as poor contact caused by battery movement.

It should be noted that, in the absence of conflict, the embodiments and features and technical solutions in the embodiments of this utility model can be combined with each other. It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] Example 1: An omnidirectional microphone loudspeaker includes a loudspeaker housing 1 and semi-circular plates 2 disposed at the four corners of the loudspeaker housing 1. A loudspeaker front panel 3 and a loudspeaker rear cover 4 are respectively installed on the upper and lower sides of the loudspeaker housing 1. The rear cover 4 is provided with anti-slip texture 5. A raised rubber pad 6 is fixed at each of the four corners of the rear cover 4. The raised rubber pad 6 is made of silicone and there are four of them arranged in a linear array.

[0032] A speaker mounting ring plate 7 is fixed on the bottom plate inside the speaker housing 1, and a speaker horn 8 is mounted on the speaker mounting ring plate 7. A battery mounting bracket 10 is connected below the speaker mounting ring plate 7. A power supply lithium battery 9 is electrically connected inside the battery mounting bracket 10, and the power supply lithium battery 9 is connected to the speaker horn 8 through a circuit wire. A reinforcing rib 11 is embedded between the battery mounting bracket 10 and the bottom inside the speaker housing 1.

[0033] The speaker housing 1 has a protective plate 12 inside, and the protective plate 12 has a U-shaped groove, on which the speaker horn 8 is located. Speaker positioning rods 13 are fixed on both sides of the protective plate 12, and a positioning rod arc head 14 is fixed on the top of the speaker positioning rod 13, while the bottom is connected to the inside of the speaker housing 1.

[0034] The speaker front panel 3 has a speaker outlet 15. A power switch 16 is electrically connected to the upper left of the speaker front panel 3, and a volume control button 17 is electrically connected to the side of the power switch 16.

[0035] A charging audio composite interface 18 is electrically installed at the bottom of the speaker housing 1, while a microphone interface 19 is provided on the top plate of the speaker housing 1. The working principle of the omnidirectional microphone speaker is as follows: the semi-circular plates 2 are set at the four corners of the speaker housing 1 to buffer and protect, reducing the impact on the internal structure when the four corners are hit.

[0036] The anti-slip texture 5 is set on the outer plate of the speaker rear cover 4 to increase the friction with the placement surface and prevent the speaker from sliding; the raised rubber pads 6 are fixed at the four corners of the speaker rear cover 4 and are made of silicone material, which not only further enhances the anti-slip effect, but also plays a role in shock absorption and avoids external vibration from damaging the internal structure of the speaker.

[0037] Sound production principle: The power supply lithium battery 9 is installed inside the battery holder 10, providing power to the entire speaker system. The power supply lithium battery 9 is connected to the speaker horn 8 via a circuit wire. When an audio signal is input, the audio signal drives the speaker horn 8 to vibrate and produce sound.

[0038] The speaker mounting ring plate 7 is fixed to the bottom plate inside the speaker housing 1 and is used to install the speaker 8 to ensure the stability of the speaker during sound production.

[0039] The reinforcing rib 11 is embedded between the battery holder 10 and the bottom of the speaker housing 1, which enhances the stability of the battery holder 10 and thus ensures a stable power supply to the lithium battery 9.

[0040] Protection and positioning: The protective plate 12 is set inside the speaker housing 1. Its U-shaped groove surrounds the speaker horn 8, which protects the horn and prevents external objects from directly hitting the horn.

[0041] The speaker positioning rod 13 is fixed on both sides of the protective plate 12. The arc-shaped head 14 of the positioning rod at the top helps to accurately install the protective plate 12. The bottom is connected to the inside of the speaker housing 1 to ensure that the position of the protective plate 12 is fixed, and further ensures the stable operation of the speaker 8.

[0042] The sound emitted by the speaker 8 is transmitted to the outside through the speaker outlet 15 on the front panel 3 of the speaker, thus realizing the playback of sound.

[0043] The power switch 16 is electrically connected to the upper left of the speaker's front panel 3 and is used to control the power supply to the entire speaker. The volume control button 17 is electrically connected to the same side as the power switch 16, and the user can adjust the speaker's volume by operating the volume control button 17.

[0044] The charging and audio composite interface 18 is installed at the bottom of the speaker housing 1. It can be used to charge the power supply lithium battery 9 and to input audio signals, realizing the composite function of charging and audio input.

[0045] The microphone interface 19 is located on the top plate of the speaker housing 1, which can be connected to an external microphone to realize sound collection and enable the speaker to have the function of an omnidirectional microphone.

[0046] The working process of the omnidirectional microphone speaker: Place the speaker on a suitable flat surface. The anti-slip texture 5 and raised rubber pad 6 on the back cover ensure that the speaker is placed stably and reduce the impact of sliding and vibration.

[0047] The charging audio composite interface 18 is used to connect to a power source using an appropriate charging cable to charge the lithium battery 9, ensuring that the battery is fully charged or has sufficient power to guarantee normal operation.

[0048] Press the power switch 16 on the upper left of the front panel 3 of the speaker, and the power supply lithium battery 9 will start to supply power to the entire speaker system through the circuit wires, and the speaker will enter standby mode.

[0049] External audio input: Audio devices can be connected via the charging audio composite interface 18 to transmit audio signals to the speaker. Sound playback: The audio signal is transmitted to the speaker 8, driving the speaker to vibrate and produce sound. The speaker fixing ring plate 7 ensures the stability of the speaker 8 during sound production. The emitted sound is propagated to the surrounding environment through the speaker outlet 15 on the front panel 3 of the speaker.

[0050] Volume adjustment: During audio playback, users can press the volume adjustment button 17 to adjust the volume of the speaker playback as needed.

[0051] Connect the microphone to the speaker via microphone interface 19. Turn on the relevant device or software (such as recording software, live streaming software, etc.), and the microphone will begin collecting ambient sound. Because the speaker has an omnidirectional structure, it can sensitively receive sound signals from multiple directions. The collected sound signals can be played directly through the speaker for amplification; alternatively, they can be transmitted via the charging audio composite interface 18 to a connected external device for further processing, such as recording or live streaming.

[0052] After use, press the power switch 16 again to cut off the power supply from the lithium battery 9 to the speaker system, and the speaker will stop working. If storage is required, disconnect the connected charging cable, audio cable, microphone, and other external devices, and store the speaker properly to avoid collisions and damage.
