Description

Technical Field

[0001] This utility model belongs to the field of loudspeaker technology, and in particular relates to a loudspeaker with waterproof measures. Background Technology

[0002] A loudspeaker is a common electroacoustic device frequently used in sound-producing electronic devices. Currently, there are many types of loudspeakers in use. A typical loudspeaker structure generally consists of a dust cap, diaphragm, voice coil, spider, bracket, washer, magnet, magnetic cover, and circuit board. Due to usage requirements, loudspeakers are often carried and used outdoors. Because of the sound-producing function of loudspeakers, an opening structure is needed on the sound-producing side. This opening structure results in poor waterproofing; when exposed to rain outdoors, raindrops can easily enter the loudspeaker's interior through the sound-producing opening, affecting its operation and potentially causing short circuits and damage to the internal circuitry. A search revealed patent application number 202420941398.8, which discloses a loudspeaker with waterproofing measures. The lower part of the loudspeaker body is enclosed and fitted inside a mounting housing, while a protective cover is securely installed on the upper part of the mounting housing.

[0003] However, during actual use, the applicant found that some rainwater flowing in from the sound amplification hole would flow along the top of the inner side of the protective cover to the top of the sound amplification hole, and drip down onto the speaker body from the sound amplification hole, thus failing to effectively protect the speaker from water. In view of this, we propose a speaker with waterproof measures. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 As shown, this utility model provides a technical solution:

[0022] A waterproof loudspeaker includes a loudspeaker body 1. The top of the loudspeaker body 1 has a sound-emitting surface 11, and the bottom of the loudspeaker body 1 has a groove 12. A charging interface 13 and a push-button switch 14 are fixedly disposed on the top of the groove 12. A waterproof cover 2 is threadedly connected to the upper part of the loudspeaker body 1. The upper end of the loudspeaker body 1 has an external thread 15, and the lower end of the waterproof cover 2 has an internal thread 21, which is threadedly engaged with the external thread 15. A vertical tube 22 is fixedly connected to the top of the inner side of the waterproof cover 2. Several vertical tubes 22 are arranged in a circular array on the top of the inner side of the waterproof cover 2. The waterproof cover is located above the vertical tubes 22. A sound-emitting through-hole 23 is provided at the top of the riser 22, which is connected to the riser 22. A sound-guiding through-hole 221 is provided on the outer wall of the upper end of the riser 22. Two sound-guiding through-holes 221 are vertically arranged on the riser 22, and they are inclined. The end of the sound-guiding through-hole 221 inside the riser 22 is lower than the end outside the riser 22, so that rainwater entering the riser 22 from the sound-emitting through-hole 23 will not flow into the sound-guiding through-hole 221. An annular water-guiding cover 24 is fixedly installed on the inner wall of the waterproof cover 2 below the riser 22. The annular water-guiding cover 24 is in the shape of an inverted trumpet, and the annular water-guiding cover 24... The lower end is fixedly installed on the inner wall of the waterproof cover 2. The outer wall of the annular water guide cover 24 is curved, so that rainwater falling from the lower outlet of the riser 22 onto the annular water guide cover 24 can flow smoothly along the outer wall of the annular water guide cover 24 to the drainage slot 25, avoiding splashing of rainwater falling onto the annular water guide cover 24. The top of the annular water guide cover 24 is higher than the lower end of the riser 22, and the top of the annular water guide cover 24 is lower than the bottom of the sound guide hole 221. Drainage slots 25 are arranged in a ring array on the outer wall of the waterproof cover 2. The bottom of the drainage slots 25 is flush with the lower end surface of the outer side of the annular water guide cover 24. The waterproof cover above the drainage slots 25 is... An arc-shaped sound-guiding surface 26 is provided on the inner wall of the cover 2. The waterproof cover 2 allows rainwater to enter the interior of the riser 22 through the sound-guiding hole 23 and then be discharged from the drain outlet 25 along the outer wall of the annular water-guiding cover 24, effectively protecting the speaker body 1 from water. The sound emitted by the speaker body 1 can enter the riser 22 through the sound-guiding hole 221 and be discharged from the sound-guiding hole 23, enabling the speaker body 1 to emit sound smoothly. Furthermore, the arc-shaped sound-guiding surface 26 allows some sound to be conducted downwards along the arc-shaped sound-guiding surface 26 and discharged from the drain outlet 25, allowing the sound to be conducted to the surrounding area at the same time.

[0023] Working principle: During use, a portion of the sound emitted by the speaker body 1 enters the riser 22 through the sound guide hole 221. A portion of the sound entering the riser 22 can be conducted upwards and discharged upwards through the sound guide hole 23, while another portion of the sound can be conducted downwards and discharged along the outer wall of the drain outlet 25. The remaining portion of the sound that does not enter the riser 22 can be conducted downwards under the action of the arc-shaped sound guide surface 26 and discharged from the drain outlet 25. In this way, sound can be conducted upwards and outwards. When used outdoors and encountering rain, some rainwater falling on the waterproof cover 2 will enter the riser 22 through the sound guide hole 23 and flow downwards along the riser 22 to the outer wall of the annular water guide cover 24. The rainwater flowing on the annular water guide cover 24 can flow downwards along the arc surface and be quickly discharged from the drain outlet 25, thereby achieving waterproof protection for the speaker body 1.
