Description

Technical Field

[0001] The present invention relates to the field of speakers, and in particular to a speaker capable of transmitting light from the middle of a woofer or tweeter of the speaker, and a speaker capable of transmitting light from the edge of the speaker. Background Art

[0002] As a portable wireless audio device, speakers add infinite fun to our daily lives, from outdoor outings to family gatherings to personal fitness moments.

[0003] Due to the portability of speakers, especially Bluetooth speakers, they are used in various occasions. In order to enhance the atmosphere of speaker use, a luminous effect is currently added to the speakers. Specifically, light sources of different colors are provided inside the speakers or light sources that can emit different colors alternately, and the light of the light source is transmitted through the speakers to enhance the use effect.

[0004] Although there are many ways to emit light from the inside, the way of allowing light to pass through the front of the speaker is far from enough to enhance the use effect. Therefore, a light-transmitting solution that can further enhance the use atmosphere effect is needed. Summary of the Invention

[0007] The speaker has a speaker, and a channel is provided on the speaker. The channel guides the light from the light source at the rear side of the speaker into the interior of the speaker and radiates the light from the front side of the speaker.

[0008] The further optimized solution is: The speaker is a woofer.

[0011] The further optimized solution is: The rear cover of the woofer is made of a light-transmitting material, and the dust cover is also made of a light-transmitting material.

[0012] The further optimized solution is: The speaker is a tweeter.

[0013] The further optimized solution is: The channel is a through hole provided on the tweeter, and the through hole connects the rear end of the tweeter with the interior of the tweeter.

[0014] The further optimized solution is: The light is emitted outward from the sound membrane on the front side of the tweeter.

By changing the area of ​​the coating, the area of ​​light emitted outward from the sound membrane can be changed. or, A polymer light-conducting material layer is provided on the inner side of the sound membrane.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] In the description of the present invention, it should be understood that the terms "center", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0026] In the present invention, unless otherwise expressly specified or limited, terms such as "disposed," "installed," "connected," "connected," and "fixed" should be understood broadly. For example, they may refer to fixed or detachable connections, mechanical connections, direct connections, or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in the present invention based on specific circumstances.

[0027] As shown in the figure, the present invention discloses a speaker, more specifically a luminous speaker. A light source is arranged inside the speaker. In order to enable the speaker to emit light of different colors, the color of the light source inside the speaker can be set to multiple colors, or multiple colors can be emitted alternately. In this case, the color and lighting method of the light source can adopt those in the existing technology, which will not be elaborated here.

[0028] The sound source of the speaker in this case can be a woofer and a tweeter, or a woofer or a tweeter, which can be selected according to the different needs of users.

[0029] Focusing on the design point of this case, a channel is provided on the aforementioned different types of speakers, which guides the light emitted by the light source on the back side / rear of the speaker into the interior of the speaker and radiates it from the front side of the speaker, so that the user can observe the light transmitted from the speaker (center) from the front side of the speaker or the front side of the speaker, thereby enhancing the light transmission effect.

[0030] The aforementioned interior is the space enclosed by the dust cover and the speaker body, or the space enclosed by the sound membrane and the speaker body.

[0031] like Figure 4 、 6 As shown, the channel can be a through hole provided on the woofer or tweeter, and the through hole connects the rear end of the woofer or tweeter with the interior of the woofer or tweeter.

[0032] The through hole is parallel to the central axis of the woofer or tweeter, and can be integrally formed when manufacturing the T-shaped iron or the U-shaped iron, or can be formed by drilling on the basis of the existing woofer or tweeter.

[0033] A plurality of through holes may be provided.

[0034] The through holes may be distributed in an array on the woofer or tweeter.

[0035] Set the channel on the subwoofer as follows Figure 3 、 4 As shown, in one embodiment, on a woofer, light radiates outward from a dust cover on the front side of the woofer. The dust cover is made of a light-transmitting material, and a light-guiding coating is applied on the inner side of the dust cover. By changing the area of ​​the coating, the area of ​​light radiating outward from the dust cover can be changed.

[0036] In another embodiment, a polymer light-guiding material layer is provided on the inner side of the dust cover, and the polymer light-guiding material layer and the dust cover are in different layers. The light is diverged at the polymer light-guiding material layer, then passes through the polymer light-guiding material layer and diverges outward from the dust cover.

[0037] For the channel settings on the tweeter, Figure 5 、 6 As shown, in one scheme, on the tweeter, light radiates outward from the sound membrane on the front side of the tweeter. The sound membrane is made of a light-transmitting material, and a layer of light-guiding coating is applied on the inner side of the sound membrane. By changing the area of ​​the coating, the area of ​​light radiating outward from the sound membrane can be changed.

[0038] In another embodiment, a layer of polymer light-conducting material is provided on the inner side of the diaphragm, but the polymer light-conducting material layer and the diaphragm are separate layers. Light is emitted from the polymer light-conducting material layer, then passes through the polymer light-conducting material layer and is emitted outward from the diaphragm.

[0039] The polymer light-guiding material layer may be a silica gel layer.

[0040] In order to enable the light entering from the channel to be reflected and refracted multiple times on the polymer light-guiding material layer, the thickness of the polymer light-guiding material layer is set to be different.

[0041] In a further preferred embodiment, the thickness of the edge of the polymer light-guiding material layer is greater than the thickness of the middle portion.

[0042] The beneficial effects of the present invention are: 1. A light guide channel is provided on the woofer and tweeter, which can guide the light emitted by the light source behind the speaker out of the middle of the speaker, increasing the area where the speaker emits light; 2. The rear cover and dust cover of the speaker are set to be translucent, which can let the light from the light source inside the speaker pass through, further enhancing the luminous effect of the speaker.
