As shown in Figures 1 to 4, a smart watch with directional sound transmission provided by the embodiment of the present invention includes a case 1 and a strap 4 connected to the case 1, and the side wall of the case 1 can be provided with Sound hole 2, a directional speaker 3 can be arranged at the sound hole 2, and the directional speaker 3 can face the sound hole 2, and the directional speaker 3 is used instead of the traditional speaker, so that the smart watch has a directional sound transmission function, and the speaker can be located at In the casing 1, it can be seen that the sound emitted by the directional speaker 3 is directionally transmitted to the outside of the casing 1 through the sound hole 2; The user is most likely to hear and will not affect the surrounding direction transmission, the structure is simple and compact, and the manufacturing process is simple. The embodiment of the utility model provides a smart watch capable of directional sound transmission, which can protect personal privacy when talking in public places, and at the same time, it will not cause noise interference when making sounds in public places. Wearing earphones, the user has a good sense of use and can really solve the problem.

As shown in FIG. 3 , optionally, an electronic component 8 , a PCB board 9 , a battery, etc. may also be arranged in the casing 1 .

As shown in Figure 1, optionally, the side wall of the housing 1 provided with the sound hole 2 can be inclined to the front of the housing 1, and the sound hole 2 can be arranged perpendicular to the side wall provided with the sound hole 2 , so that the sound emitted by the directional loudspeaker 3 in the casing 1 can be transmitted along the direction that the user can most easily hear without affecting the surroundings, the structure is simple and compact, and the manufacturing process is simple.

Or, as another implementation of the sound hole 2, the side wall of the casing 1 provided with the sound hole 2 can be arranged perpendicular to the front of the casing 1, and the sound hole 2 can be inclined to the side wall provided with the sound hole 2. Sidewall settings.

As shown in Figures 1 and 2, optionally, the sound outlet 2 may include an inner sound outlet 21, a sound outlet channel 23 and an outer sound outlet 22, and the inner sound outlet 21 and the outer sound outlet 22 may be respectively arranged on the outlet At both ends of the sound hole 23, the sound outlet 2 can be arranged on the inside of the side wall of the housing 1, and the outer sound outlet 22 can be arranged on the outside of the side wall of the housing 1, that is, the inner sound outlet 21 is connected to the inside of the housing 1. The sound outlet hole 23 and the outer sound outlet hole 22 are connected to the outside of the casing 1 and the sound outlet hole 23, and the sound outlet hole 23 can be connected to the inside and outside of the side wall of the casing 1;

An inclined angle α can be formed between the sound outlet channel 23 and the front of the housing 1 , and the angle range of the inclined angle α is 10°-75°. It is understandable that the traditional sound outlet is perpendicular to the horizontal plane of the shell. When the user needs to hear the sound from the speaker well, he needs to turn his wrist to a certain angle. After listening for a long time, the wrist will be tired; and this implementation In the example, the sound channel 23 of the smart watch forms an angle with the front of the housing 1. When the user needs to hear the sound from the directional speaker 3 clearly, he only needs to raise his hand and bring the smart watch close to his ear without turning his wrist. , and the angle of the inclined angle α can be set in different specifications according to the needs of different users, which can meet the requirements of different users.

In this embodiment, the side wall of the housing 1 inside the housing 1 is defined as the inside of the side wall of the housing 1; on the contrary, the side wall of the housing 1 outside the housing 1 is defined as the housing 1 outside of the side wall.

As shown in FIGS. 1 and 3 , optionally, the sound hole 2 may be located at the place where the side wall of the case 1 is connected to the strap 4 . It can be understood that if the smart watch has a pointer dial, the sound hole 2 is located on the side wall of the housing 1 and the pointer points to the position of 6 o'clock. Usually, this position is connected with the strap 4 and is close to the face when worn and used.

As shown in Figure 3 and Figure 4, optionally, the directional speaker 3 can be a miniature audio frequency directional speaker, which is often used in mobile phones, and provides local sound services for users in a hands-free manner to establish good privacy Sound space: the audible audio signal is modulated into the ultrasonic signal, and the nonlinear propagation effect of the ultrasonic wave in the signal is used to generate a series of virtual sound sources distributed along the propagation axis through the ultrasonic transducer array. Known as parametric arrays, they control the propagation of sound in a narrow and long area, and then form a highly directional audible sound beam 7, thereby realizing the directional propagation of sound when the smart watch is talking.

As shown in Figures 1 and 3, optionally, a display screen 5 may be provided on one side of the casing 1, and a rear cover 6 may be provided on the other side, that is, a display screen 5 is provided on the front of the casing 1, and a display screen 5 is provided on the front of the casing 1. There is a back cover 6 on the back; the inner sound hole 21 can be close to the back cover 6, and the outer sound hole 22 can be close to the display screen 5, that is, when wearing a smart watch and making a call, the sound hole 2 faces the face, which is good for the user to hear clearly sound. Of course, the inner sound hole 21 can also be close to the display screen 5, and the outer sound hole 22 can also be close to the rear cover 6, depending on different wearing and using methods of different users, the structure is simple and flexible.

As shown in Figure 1, optionally, the aperture of the inner sound outlet 21 can be larger than the aperture of the outer sound outlet 22, which is conducive to the concentrated transmission of the sound emitted by the directional speaker 3, which can further reduce the range of sound transmission and improve the smart watch. Confidentiality of Calls.

Optionally, the directional speaker 3 may have a front sound chamber 31 , and the front sound chamber 31 may face the sound outlet 2 , so that the sound is more concentrated and transmitted from the sound outlet 2 to the outside of the housing 1 more easily.

Optionally, the display screen 5 may be a touch display screen 5 .

The embodiment of the utility model provides a smart watch capable of directional sound transmission, which uses a directional speaker 3 instead of a traditional speaker, and utilizes the characteristics of directional sound transmission of the directional speaker 3 to allow the smart watch to transmit sound directionally during a call; and The sound hole 2 can be set obliquely upward. When the directional speaker 3 is working, an audible sound beam 7 will be generated through the sound hole 2. The user only needs to raise the wrist appropriately and align the sound hole 2 with the direction of the ear. It is very safe and convenient to complete normal calls or listen to songs, and can effectively solve the call privacy and noise pollution, and does not need to use headphones to solve the problem, and does not need to wear headphones at all times, bringing users a good call environment and experience. Really solve the problem.
