Description

Technical Field

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

[0002] Mobile phone speakers are divided into three types: mono, stereo, and two-channel. In mono audio equipment, you can only perceive the position of the sound and music, as well as the timbre and volume, but you cannot perceive the lateral movement of the sound from left to right. Simply put, it has two sound channels, and in the circuitry, they often transmit different electrical signals. Due to technological limitations, electroacoustics initially could only achieve stereo sound by using two-channel technology in their pursuit of stereo audio.

[0003] To ensure the waterproof performance of speakers, an insulating cavity is usually made on the outside of the speaker, but the insulating cavity will affect the propagation of sound. Utility Model Content

[0004] To address the aforementioned technical problems, a waterproof speaker is provided.

[0005] To achieve the above objectives, in a preferred embodiment of the present invention, the present invention includes a speaker body, a non-contact diaphragm is laid above the sound outlet of the speaker body, and a sealing structure is provided at the edge of the diaphragm, which is sealed to the speaker body and the cover body through the sealing structure.

[0006] In a preferred embodiment, the present invention may be further configured such that the membrane includes a sound-permeable and waterproof membrane, the sound-permeable and waterproof membrane being circular in shape and covering the sound outlet of the speaker body.

[0007] In a preferred embodiment, the present invention may be further configured such that the sealing structure includes a protrusion, the protrusion being an annular body disposed at the edge of the diaphragm, and disposed within a cavity of the same shape formed by the cover and the speaker body.

[0008] In a preferred embodiment, the present invention may be further configured such that the volume of the protrusion is smaller than the volume of the cavity, and adhesive is provided in the gap.

[0009] In a preferred embodiment, the present invention may be further configured such that a recessed groove is provided near the protrusion of the sound-permeable waterproof membrane, and the bottom of the recessed groove is in contact with the speaker body.

[0010] In a preferred embodiment, the present invention may be further configured such that an arc-shaped dust cover is provided at the center of the cover opposite the sound outlet of the speaker body, and several through holes are vertically opened on the cover of the dust cover.

[0011] Beneficial effects: The waterproof speaker of this utility model has an additional membrane layer on the top of the speaker body. This membrane can transmit sound but isolate liquid, and the sealing structure at the edge of the membrane can ensure that there is no leakage at the connection. Attached Figure Description

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0013] Figure 1 This is a schematic diagram of the overall structure of this utility model.

[0014] Figure 2 This is an enlarged schematic diagram of part A of this utility model.

[0015] In the diagram, 1 is the speaker body; 2 is the sound-permeable and waterproof membrane; 3 is the dust cover; 4 is the cover body; and 5 is the protrusion. Detailed Implementation

[0016] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1 and Figure 2 As shown, a waterproof loudspeaker includes a loudspeaker body 1. A non-contact membrane is laid above the sound outlet of the loudspeaker body 1. A sealing structure is provided at the edge of the membrane, which is sealed to the loudspeaker body 1 and the cover 4 through the sealing structure.

[0018] The membrane includes a sound-permeable and waterproof membrane, which is circular in shape and covers the sound outlet of the speaker body 1.

[0019] The sealing structure includes a protrusion 5, which is an annular body disposed at the edge of the diaphragm and is disposed within a cavity of the same shape formed by the cover 4 and the speaker body 1.

[0020] The volume of the protrusion 5 is smaller than the volume of the cavity, and adhesive is provided in the gap.

[0021] The sound-permeable waterproof membrane has a recessed groove near the protrusion 5, and the bottom of the recessed groove is in contact with the speaker body 1.

[0022] The center of the cover 4 is provided with an arc-shaped protruding dust cover 3 facing the sound outlet of the speaker body 1, and several through holes are vertically opened on the cover of the dust cover 3.

[0023] It should be noted that in this article, relational terms such as first and second are used only to distinguish one entity from another, and do not necessarily require or imply any such actual relationship or order between these entities.
