It should be noted that the drawings are very simplified and use non-precise proportions, only to facilitate, clear and assist in the purpose of illustrating the embodiments of the present application.

[0029] Embodiment one

[0030] Please refer to Figures 3 to 5 The present embodiment provides a wide audio channel electronic equipment.

[0031] Specifically, in the present embodiment, the airflow will directly act on the display screen because the shell is excavated in the vertical direction, which may cause damage to the display screen. Since the pressure resistance of different display screens is different, the selection of sealing material 4 and sealing position needs to be differentiated. In order to ensure that the display screen of various materials can be effectively sealed with the front shell, the present embodiment proposes the following specific structure of the wide audio channel electronic equipment.

[0032] Please refer to Figure 3The electronic device with a wide audio channel provided by the embodiment comprises a loudspeaker core, a front shell and a screen 5 arranged in sequence; the front shell comprises a first front shell 1 and a second front shell 2, and the first front shell and the second front shell have a distance therebetween; two end bottom surfaces of the first front shell 1 and the second front shell 2 oppositely arranged are provided with grooves 6, and the openings of the grooves 6 face the screen 5; the grooves 6 are filled with sealing materials 4, or the surface of the screen 5 is paved with sealing materials 4; an audio channel is formed between the loudspeaker core and the screen 5, and the thickness of the audio channel is l2; or the audio channel is formed between the loudspeaker core and the sealing layer, and the thickness of the audio channel is l1.

[0033] In the embodiment, the front shell part is excavated in the vertical direction, and an audio channel is formed between the loudspeaker core and the screen or between the loudspeaker core and the sealing layer; through the above design, the audio channel is widened, so that the sound effect of the loudspeaker is improved. In addition, after the front shell is excavated, the distance between the loudspeaker core and the screen can be further reduced, so that the thickness of the loudspeaker as a whole is reduced. Further, for screens of different materials, different sealing materials are used between the front shell and the screen to improve the air tightness of the audio channel, thereby providing users with a better use experience.

[0034] In the embodiment, the thickness of the groove 6 is greater than or equal to 0.8 mm, for example, 0.9 mm, 1 mm, 1.2 mm and 1.3 mm. Those skilled in the art can select grooves 6 with different thicknesses according to the preparation requirements of the loudspeaker.

[0035] In the embodiment, the material of the active material layer of the screen 5 can be LCD (liquid crystal display), OLED (organic light-emitting diode), AMOLED (active matrix organic light-emitting diode) or Mini-LED (mini light-emitting diode) and the like. Those skilled in the art can select different materials according to actual conditions.

[0036] For reference Figure 4 When the material of the front shell is OLED material, the OLED (organic light-emitting diode) screen 5 has high pressure resistance, and the screen 5 and the front shell can be directly sealed by using a foam or other elastic sealing material 4.

[0037] Specifically, the foam can be filled into the groove 6 arranged at the end bottom surface of the first front shell 1 and the second front shell 2 oppositely arranged.

[0038] In one embodiment, the width of the groove 6, i.e. the distance between the screen 5 and the top of the groove 6, is at least 0.8 mm, and thus the width of the foam also needs to be at least 0.8 mm, so that the foam fills the groove 6 provided in the oppositely arranged end portions of the first front shell 1 and the second front shell 2, thereby achieving effective sealing between the first front shell 1 and the second front shell 2.

[0039] Further, it can be understood that for a non-OLED (organic light-emitting diode) screen 5, the screen 5 has a lower voltage resistance strength, and thus is more likely to be damaged during extrusion, thereby forming white spots or other visible damages on the screen 5. Therefore, it is necessary to increase the sealing material 4 made of PET (polyethylene terephthalate), steel sheet or other harder materials, which can provide stronger support and protection, effectively absorb external impact and protect the screen 5 from direct damage.

[0040] For reference Figure 5 In one embodiment, when the screen 5 is not made of OLED material, the specific sealing process is to apply a layer of adhesive on the groove 6 of the front shell and the surface of the screen 5, and then adhere the PET through the adhesive.

[0041] It can be understood that although the PET film has high strength and heat resistance, it can be used to protect the screen 5 from mechanical damage during assembly. However, the PET may be deformed under the action of air flow (such as a hot air gun).

[0042] Therefore, a steel sheet with higher strength and stability can be used to prevent the sealing material 4 from deforming during the air flow process. Alternatively, a layer of foam can be reserved between the PET and the screen 5 to absorb external pressure and prevent the PET from deforming and directly pressing the screen 5 during the air flow process.

[0043] It can be understood that PET is a common plastic material as a thermoplastic polymer with moderate hardness, and its raw material cost is lower than that of a steel sheet, and its processing cost is also lower than that of a steel sheet. A person skilled in the art can select either of the two sealing materials 4 according to the actual situation. Further, in addition to the two materials described above, a person skilled in the art can also select a sealing material 4 made of different materials according to factors such as the air flow pressure in the front cavity channel, the external pressure that the equipment may suffer, the overall structural strength of the equipment and the preparation cost. For example: hardened steel and hard alloy.

[0044] The embodiment prevents airflow from directly damaging the screen 5 and prevents water vapor and dust from entering the gap between the screen 5 and the front shell of the mobile phone, thereby avoiding damage to the loudspeaker and improving the service life of the loudspeaker. In addition, by providing the groove 6 in the first front shell 1 and the second front shell 2, when the screen 5 is made of a material with high pressure resistance such as OLED, the groove 6 can be directly filled with foam for sealing. When the screen 5 is made of a material such as LCD, the groove 6 can be filled with foam, and a hard sealing material such as PET or steel sheet can be laid on the surface of the screen 5 to connect the foam in the groove 6 for sealing. It can be seen that the loudspeaker with the above structure can effectively seal the display screen and the front shell made of various materials.

[0045] In the embodiment, the sealing materials are adhered by adhesive, and the sealing materials, the back shell and the screen 5 are also adhered by adhesive. It can be understood that those skilled in the art can select different adhesion methods according to actual conditions.

[0046] In a specific embodiment, the size is calculated according to the height of a 1511 common 0.3mm amplitude loudspeaker. Under the condition of meeting the audio performance, the non-OLED screen 5 is stacked, and the thickness of the whole machine can be at least 8.22mm, which is 0.14mm thinner than before. The sealing method is to lay a steel sheet, PET or other harder material on the surface of the screen 5, and fill the foam in the groove 6, and connect the above sealing materials 4 with the screen 5 and the back shell by adhesive.

[0047] It can be understood that the electronic device with a wide audio channel disclosed in the embodiment can be a terminal device such as a mobile phone and a tablet computer.

[0048] Please refer to Figure 6 , Figure 6 The test result graph of the FR (frequency response) data detection of the four sample machines of the electronic device provided with the above wide audio channel is shown in the figure. As can be seen from the figure, when the audio frequency (Frequency) is about 1000HZ, the sound pressure level reference value (SPL) is about 95db; please refer to Figure 7 , Figure 7 The test result graph of the THD (total harmonic distortion) data detection of the four sample machines of the electronic device provided with the above wide audio channel is shown in the figure. As can be seen from the figure, the maximum total harmonic distortion is about 20%; please refer to Figure 8 , Figure 8 The test result graph of the R&B (rubbing noise and humming sound) data detection of the four sample machines of the electronic device provided with the above wide audio channel is shown in the figure. As can be seen from the figure, the maximum R&B value is about 0.5%; please refer to Figures 6-8It can be seen that the three test result graphs can prove that the performance of the prototype of the electronic device provided with the wide audio channel in Embodiment One meets the requirements.

[0049] Various modifications and changes can be made as would be obvious to one skilled in the art without departing from the spirit and scope of the application. It is intended that the application include all such modifications and changes as fall within the scope of the claims and their equivalents.
